Defence Market Speculation: Boom and Bust in Aerospace Industry

Following piece is written by Rick Whittington, taken from Aerospace And Defense Picks For 2011 (17-12-10). Recently both UK and USA defence budgets were revised with further revision in defence policies. Recent retirement of RAF’s Harrier, and delays in F-35 has created a big gap within RAF inventory. Not only that Both BAe Systems and Rolls Royce has seen declines after recent Qanatas Incident. From civilian market, Seattle Time cites that as Boeing prepares to announce yet another delay for the 787 Dreamliner — at least three months, possibly six or more — the crucial jet program is in even worse shape than it appears. A top Federal Aviation Administration (FAA) official 10 days ago warned Boeing that without further proof of the plane’s reliability, it won’t be certified to fly the long intercontinental routes that airlines expect it to serve. Since then share prices are on continuous decline for Boeing. Among the 787’s lesser ongoing problems is “rain in the plane,” the term used for heavy condensation dripping inside the jet’s composite plastic fuselage. Yet that issue is piddling compared with the major flaws that have brought a wave of successive delays. Earlier this month, John Hickey, the FAA’s deputy associate administrator for aviation safety, visited Seattle and warned 787 executives that in the current state of the program, the jet cannot be certified for long-distance transocean and transpolar flights, according to a person familiar with the details.

A fiscally focused trend in U.S. politics means defense spending may drop in 2011. Which aerospace companies will bust and which will boom regardless? Secular change in the U.S. political landscape augurs poorly for defense fundamentals, with fiscal rectitude offsetting China’s brusque ascent on the world scene–an ascent that would otherwise dictate modernization to offset an increasingly sophisticated major power. Following a near decade of above-trend reports, earnings of military suppliers are set for several difficult years, as hard-won margin gains in the Bush years reverse, revenues reduce and backlogs diminish. Just how far the decline will carry remains largely out of public view, as long-range budget details are classified, but Washington circles are already abuzz with steep funding drops in weapons modernization and force structure.

The company's original internal target for its own development costs was $5 billion. But with yet another delay, several Wall Street analysts estimate that fixing the litany of manufacturing problems, plus paying penalties to suppliers and airlines, has piled on an additional $12 billion to $18 billion.

Ongoing budget review, which in Washington goes on all year, is already producing shock waves in contractor circles as word leaks out of the bad news ahead. Actually, many had figured out the deteriorating trend two years ago when a new administration was swept into power, but most held their breath hoping the worst case wouldn’t develop. Unfortunate for the bull case, however, the Republican tidal wave this past election is distinctly tinged with fiscal austerity, with national security taking a back seat. The deleterious impact on defense contractors has finally begun trickling into Wall Street views and the stocks are rolling over.

Pure-play suppliers that have most benefited from the longest conflict in American history–the Revolution’s eight-year employment of Washington’s Continentals has been surpassed by forces in the field in Iraq and Afghanistan–are highly vulnerable to the downsizing that lies ahead. The likes of Lockheed, Northrop-Grumman, Raytheon ( RTN – news – people ), L-3 and General Dynamics ( GD – news – people ) face big funding cuts that seriously compromise earnings integrity and could even create black holes necessitating serious corporate restructuring. Past periods like this have seen steep valuation discounts for the pure-plays.

On the other hand, commercial aviation and industrial infrastructure companies continue to guide up as the business cycle recovery of nearly two years ago gains steam. U.S. business confidence began improving as Congress promised to change hands, meaning additional unfriendly legislation was averted and commerce-centric policies were brought to center stage. Tax cuts will now be followed up with fiscal restraint, incenting hiring and fixed investment projects. Until money measurably tightens, a virtuous cycle encompassing developed world capital goods exporters and consumers will continue to fuel aggregate demand and push earnings higher.

Many think the best plays are in emerging markets, as their growth is much stronger than in far larger, developed economies. Our view, however, turns this consensus perspective on its head, seeing domestic U.S. equities as the preferred plays where they derive principal impetus from global growth. Our favorites include a host of commercial aviation and industrial suppliers that benefit from rising trade flows, demand for aircraft passenger travel and freight. Multi-industry aerospace and industrial companies bring the best of both worlds.

Delay-plagued Boeing ( BA – news – people ) will eventually right the 787 and surmount prior decade outsourcing and partnering decisions that have severely hampered program efficacy. As investors await word on when flight tests will resume and the extent to which deliveries are rescheduled, good news from other quarters is helping offset the latest disappointments. Increased production of other airliner models enjoying strong margins, notably the 777 but also 737 and a re-engineered 747, as well as price hikes combine with ongoing reports of airline profitability and upgraded air traffic forecasts.

Then, there’s also some good news unique to Boeing on the defense front. Overseas sales of fighter aircraft and helicopters to Saudi Arabia and possibly India combine with potentially quite consequential F-35 delays and new generation satellites for both government and commercial customers. As the Chinese build increasingly advanced twin-engine fighters, the U.S. and its Asian allies must confront single-engine, multi-mission F-35s without commensurate aerial superiority. With the F-22 now cancelled and its production base dismantled, there’s no ready response other than more Boeing F-18s. The Navy is already getting extras and we’d guess others will line up behind.

Tag along suppliers to Boeing and Airbus, as well as a handful of business and regional jet makers, include predominantly civil aviation oriented Goodrich ( GR – news – people ), BE Aerospace ( BEAV – news – people ) and Spirit AeroSystems. Spanning a broad gamut of advanced capital goods and industrial materials are diversified suppliers Precision Castparts ( PCP – news – people ), United Technologies ( UTX – news – people ), Honeywell ( HON – news – people ), Eaton and Parker-Hannifin, each a proxy for global infrastructure growth. United Tech and Honeywell just issued bullish 2011 initial views that will likely see upsides as the New Year rolls out.

Then there are companies with greater military exposure, such as electro-mechanical automation supplier Moog, advanced composites supplier Hexcel ( HXL – news – people ) and electronics-denominated navigation, communications and avionics specialist Rockwell-Collins. Each of these should see non-defense segments outweigh prospective cuts in military spending. Other mixed suppliers straddling the two worlds that will have a more difficult time in the years ahead include Esterline, FLIR Systems ( FLIR – news – people ) and AAR Corporation ( AIR – news – people ). These shares could face growing headwinds, especially as U.S. troops begin to draw down in Afghanistan.

X-37B: Robotic Orbital Spy

This artist's rendition shows the X-37B as it might look like orbiting Earth

Mid 2010 has seen US Air Force to Launch unmanned and reusable X-37B to orbit from Florida. The Boeing X-37 Orbital Test Vehicle is an American unmanned spacecraft. It is operated by the United States Air Force for orbital spaceflight missions intended to demonstrate reusable space technologies. The Air Force has fended off statements calling the X-37B a space weapon, or a space-based drone to be used for spying or delivering weapons from orbit.

X-37B is roughly one fourth the size of the space shuttle. It’s onboard batteries and solar arrays (pictured at left from its NASA days) can keep it operating for up to nine months according to the Air Force. It is similar to the shuttle with payload doors exposing a cargo area, and uses a similar reentry procedure before gliding to a runway. In the case of the X-37B, the vehicle will autonomously return to earth and land itself using an onboard autopilot. The primary landing spot is Vandenberg Air Force Base in California.

The program was transferred to the Department of Defense in 2004. Since that time the X-37 has become a classified program, raising questions as to whether or not it would become the first operational military space plane. During the 1960s, the Air Force and Boeing conducted research on the X-20 Dyna-Soar space plane.

On 17 November 2006 the U.S. Air Force announced it would develop the X-37B from the NASA X-37A. The Air Force version is designated X-37B Orbital Test Vehicle (OTV). The OTV program builds on industry and government investments by DARPA, NASA and the Air Force. The X-37B effort will be led by the Air Force Rapid Capabilities Office, and includes partnerships with NASA and the Air Force Research Laboratory. Boeing is the prime contractor for the OTV program. The X-37B was originally scheduled for launch in the payload bay of the Space Shuttle, but following the Columbia accident, it was transferred to a Delta II 7920. It was subsequently transferred to a shrouded configuration on the Atlas V following concerns over the unshrouded spacecraft’s aerodynamic properties during launch.

So, what makes this vehicle different fron conventional satellite? To NASA, the X-37 was projected to be an orbital experimental vehicle to be lifted to orbit by the Space Shuttle or a reusable launch vehicle and returned to Earth under its own power. But, Air Force argues that a vehicle such as the X-37 could be a valuable platform for intelligence gathering with the advantage of a satellite’s point of view, but the flexibility of an aircraft that can be launched relatively quickly and maneuvered in orbit much easier than a traditional satellite. The service directly supports the Defense Department’s technology risk-reduction efforts for new satellite systems. By providing an ‘on-orbit laboratory’ test environment, it will prove new technology and components before those technologies are committed to operational satellite programs.” The X-37 is expected to operate in a velocity range of up to Mach 25 on reentry. Among the technologies to be demonstrated with the X-37 are improved thermal protection systems, avionics, the autonomous guidance system and an advanced airframe. The X-37 has a payload bay available for experiments and other space payloads. It features thermal protection systems that are improved from previous generations of spacecraft.

Is this another ambitious NASA project or SR-71 replacement for intelligence gathering or robotic spy?

Boeing A160 – VTOL UAVs Comes to Age

FARNBOROUGH 2010: Boeing A160 Hummingbird

Farnborough 2010 (July.10) Boeing – A US aerospace company’s massive showing, included its own unmanned air vehicle pavilion. With an 11m (36ft) rotor diameter nearly as wide as the 10.7m autonomous helicopter is long, it is larger than other vertical take-off UAVs. But weighing in at 1,135kg (2,500lb), with its largely composite frame, it is also lighter, making up for the fact that it carries 45kg more than its weight in fuel. However, what makes the A160 unique is not something visible in its low-drag, reduced radar profile silhouette.

In conventional helicopters, the revolutions per minute of the rotors is normally locked in for a maximum forward speed, given weight and altitude considerations. At maximum forward speed, the tip of the advancing blade moves at speeds slightly under Mach 1, avoiding the drag and vibration seen at higher speeds. But being locked into a constant maximum rotor RPM also means that anything less that maximum forward speed – a hover, low-speed forward flight – the rotor is moving far faster than actually necessary, wasting fuel and creating drag, shortening the helicopter’s range. Humming Bird so far managed to fly at the speed of 165kt (305km/h) – with a service ceiling of between 20,000ft and 30,000ft and a range of around 2,500nm (4,620km). It is its blades that makes it unique, for range and speed compared to other in its class. For A160, the stiffness and cross-section of the rotor blades vary along their length. The low-loading hingeless design allows for changing RPMs to optimise efficiency at different speeds and altitudes. The Hummingbird has come a long way since the diesel-powered, variable-speed rotor experiment that was awarded a 30-month technology demonstration contract in March 1998. The first true Hummingbird prototype, a three-bladed design, debuted in December 2001 and had its first forward flight the following month at former US Air Force base at Victorville, California, using a Subaru engine.

In September 2003, DARPA awarded Frontier a $75 million contract for the design, development and testing of four A160s. By May 2004, Boeing had purchased Frontier from Karem. In August 2005, Frontier Systems – now a Boeing subsidiary – received a $50 million contract from the Naval Air Warfare Center Aircraft Division to examine the affordability of long-range VTOL UAVs for payload delivery. With no orders on the books, Boeing made the decision in late 2009 to put the helicopter into production, an unusual move in a business where manufacturers usually wait for a contract award or at least a military requirement before opening production. The A160 has already demonstrated its ISR capabilities to the US Army, as far back as 2008, at an annual C4ISR exercise at Fort Dix in New Jersey. Operating at the army’s Class IV UAV for the exercise, the Hummingbird integrated five different payloads for the event, Lavoranda says, including a 380mm (15in) Wescam electro-optical/infrared sensor ball and two mini tactical common datalink transceivers used to downlink full motion video from the EO/IR sensor Rover terminals to both mounted and dismounted troops with Rover terminals. The Hummingbird also proved its role as a communications relay, keeping two Humvees in contact when they moved out of the line of sight. In March, during six flights in two days, the A160 demonstrated its autonomous cargo delivery capabilities to the Marines, Wattam says, consistently delivering sling-loaded cargo within 1.2m of the target drop site. Furthermore, the A160’s proprietary, portable ground control system makes it possible to deliver cargo without a trained UAV pilot at the delivery site. After the UAV flies its pre-planned route, it stops and orbits until someone at the forward delivery location instructs it, with the touch of a button, to proceed to the inbound delivery point. Once there, another click tells it to hover over the delivery point. Adjustments can be made within a 1km range of the original delivery site before instructing the Hummingbird to lower its load, release the cable and head home on its predetermined path.

Unmanned Cargo Resupply Contract

K-MAX unmanned aircraft

According to the Sources Lockheed, together with manufacturer Kaman Aerospace, will get $45.8 million to operate the K-Max – who is copable of carrying 2721.6kg (6,000lbs) of cargo at sea level and more than 1,814.3kg (4,000lbs) at 10,000ft – while Boeing will receive $29.2 million to use its A160T Hummingbird to deliver cargo to Marines in Afghanistan. The Hummingbird, designated the YMQ-18A by the Pentagon, with its patented adjustable rotor speed technology, holds the record for endurance in its class, at 18.7h. In August 2010 the A160T Hummingbird underwent jungle test flights in Belize to test the ability of DARPA FORESTER foliage-penetrating radar to penetrate jungle cover. What makes this UAV unique is the incorporation of many new technologies – such as advance composite materials, Optimum Speed technology, ability to shift to another gear, and finally fthe uselage’s two large, stiff monocoque skins which help keep the frequency ranges of the structure outside the frequency ranges of the rotor as it changes its speeds.

E-Bomb – Direct Energy Warfare

6th Generation Aircraft - Airforces to End the Desire for Pilots

The rules of battle have changed over the entirety of military history. Tools such as technology, strategy, tactics and weapons have been the principal elements determining what kind of rules apply to the battlefield. What can consititute to a sixth generation fighter jets – Thats the question I am asking myself since past week. Although it might be too early to think of these questions, when even planes like JSf, PAK-FA or F-22 are not even fully opertional. The contemporary military rivalry is driven mostly by the ongoing military technical revolution. In particular, the weapons used on the future battlefield will play an important role in military affairs. Which weapons can play a key role in the future? I will try not to be too technical, such that the article is applicable to general public as well, however, I have included the research papers and appropriate links for those intending to explore more about E-Bombs or Electromagnetic Weapon Systems.

Sixth generation jet fighters are currently conceptual and expected to enter service in the United States Air Force and United States Navy in 2025-2030 timeframe. The technological characteristics may include the combination of fifth generation aircraft capabilities with unmanned capibility, unrefueled combat radius greater than 1000 nm and Direct Energy Weapon. It is latter which is a subject of this article. One form of this energy is Electronic Bomb (E-Bomb). This article aim to explore the technical aspects and potential capabilities of this type of bomb, target measurements and its comparison with other form of electromagnectic weaponry.

Research has shown that it is possible to develop such kind of device. Directed Energy research originated with research work done to determine the impact to important military systems operating in harsh electromagnetic environments. One of the most threatening and pervasive of all electromagnetic threats is that due to electromagnetic pulse.

These pulses can burst of electromagnetic radiation that results from an explosion (usually from the detonation of a nuclear weapon) and/or a suddenly fluctuating magnetic field. However, its not only the nuclear weapon who generates these pulses, Non-nuclear electromagnetic pulse (NNEMP) is an electromagnetic pulse generated without use of nuclear weapons. There are a number of devices that can achieve this objective, ranging from a large low-inductance capacitor bank discharged into a single-loop antenna or a microwave generator to an explosively pumped flux compression generator. To achieve the frequency characteristics of the pulse needed for optimal coupling into the target, wave-shaping circuits and/or microwave generators are added between the pulse source and the antenna. A vacuum tube particularly suitable for microwave conversion of high energy pulses is the vircator. These HEMP induced stresses can damage or severely disrupt some electronic systems, which are sensitive to transient disturbance. Significant potential damaging effects can occur at long ranges to virtually all systems located within line-of-sight of the detonation point. Thus it is feasible to say, that NNEMP generators can be carried as a payload of bombs and cruise missiles, allowing construction of electromagnetic bombs with diminished mechanical, thermal and ionizing radiation effects and without the political consequences of deploying nuclear weapons.

The fact that an electromagnetic pulse is produced by a nuclear explosion was known since the earliest days of nuclear weapons testing, but the magnitude of the EMP and the significance of its effects were not realized for some time. As a result of the test, a very short but extremely intense electromagnetic pulse was observed. This pulse propagated away from its source with a decreasing intensity, which is also to be expected according to the theory of electromagnetism.

According to the CBS reports dated March 2003 stated the application of experimental EM Pulse:

The U.S. Air Force hit Iraqi TV with an experimental electromagnetic pulse device called the “E-Bomb” in an attempt to knock it off the air and shut down Saddam Hussein’s propaganda machine. The highly classified bomb created a brief pulse of microwaves powerful enough to fry computers, blind radar, silence radios, trigger crippling power outages and disable the electronic ignitions in vehicles and aircraft. Officially, the Pentagon does not acknowledge the weapon’s existence.

Direct Energy Warfare

Military action involving the use of directed-energy weapons, devices, and countermeasures to either cause direct damage or destruction of enemy equipment, facilities, and personnel, or to determine, exploit, reduce, or prevent hostile use of the electromagnetic spectrum through damage, destruction, and disruption. The defensive part of Electronic Warfare includes the offensive actions such as preventing the enemy’s use of the electromagnetic spectrum through counter measures such as damaging, disrupting, or destructing the enemy’s electromagnetic capability. Such weaponry (DEW) is an evolving addition to the EW.

Characteristics of Direct Energy Weapons

The most common characteristics of the direct energy weapons is that they attack at the Speed of Light. This pose some advantage over conventional weaponry, This helps in defeating targets
such as theater and ballistic missiles before they can deploy defense-saturating sub-munitions. Another advantage of such weapons is that they can be used against multiple targets at the same time. The direct energy weapons are classified into four catagories; High Power Microwave (HPM), Charged Particle Beams (CPB), Neutral Particle Beams (NPB) and High Energy Laser (HEL). It is the latter which is highly potential for military applications (both stratagic and tactical missions). However, for E-Bomb it is HPM is a base. But offcourse when compared to Laser technology, the microwave technology lags in terms of research. HPM – use electromagnetic radiation to deliver heat, mechanical, or electrical energy to a target to cause various, sometimes very subtle, effects. When used against equipment, directed electromagnetic energy weapons can operate similarly to omnidirectional electromagnetic pulse (EMP) devices, by inducing destructive voltage within electronic wiring. The difference is that they are directional and can be focused on a specific target using a parabolic reflector. High-energy radio frequency weapons (HERF) or high-power radio frequency weapons (HPRF) use high intensity radio waves to disrupt electronics. However, High and low power, Pulsed Microwave devices use low-frequency microwave radiation which can be made to closely mimic and interact with normal human brain waves having similar frequencies. Although belong to the same family of technology, the E-Bomb deployment differes from that of HPM.

Potential for Aircraft Operations

Scleher, D. Curtis in Electronic warfare in the information age, has defined the potential of these kind of weapons for Aircraft Operations. DEWs have great potential for aircraft operations since crews can enhance their own survivability in the battlefield, where the aircrafts are susceptible and vulnerable to missile threats, by protecting themselves with electromagnetic shields. In such environment, DEW systems may prevent the aircraft from threats by decreasing the detection and targeting capability of enemy. They may also aid in hit avoidance by deflecting, blinding, or causing the incoming missile to break lock and finally, where necessary, to destroy the missile itself before it reaches its target. An additional approach might be to defeat the fusing system of the incoming missile. However, when deploying these bombs, getting the projectile successfully right is the key, such that useful damage can be produced. Further information about the deployment of these DEWs can be accessed from Electronic warfare in the information age. By this stage one difference between HPM and E-bomb is apparanet, despite belonging to same technological family, and this difference is their deployment. HEMP – High Altitude Electromagnetic Pulse is not a directed energy weapon. The reason why HEMP is defined as an electromagnetic weapon is that it produces similar effects in electromagnetic spectrum and can cause similar impacts on electronic devices. The potential effects of a designed HPM weapon strongly depends on the electromagnetic properties of the target. Since it is difficult to get the required intelligence, the complexity of real systems poses technical difficulties. A typical HPM weapon system basically includes a prime source that generates the intended power, an RF generator, a system that shapes and forms the wave into the intended form, a waveguide through which the generated wave travel, an antenna that propagated the wave, and the control unit that manages all the steps.

AGM-154 Joint Standoff Weapon l

Delivery system considerations for E-bombs are very important. The massed application of such electromagnetic weapons in the opening phase of an electronic battle delivered at the proper instant or location can quickly lead the superiority in the electromagnetic spectrum. This package might mean a major shift from physically lethal weaponry to electronically lethal attacks (via e-bombs) as a preferred mode of operation. Potential platforms for such weapons delivery systems are AGM-154 JSOW (Joint Stand Off Weapon) glidebomb (shown above) and the B-2 bomber (shown below). The attractiveness of glidebombs delivering HPM warheads is that the weapon can be released from outside the effective radius of target air defenses, minimizing the risk to the launch aircraft, which can stay clear of the bomb’s electromagnetic effects.

B2-Bomber refueling

Another delivery method of e-bomb may be the use of UAVs. The technology of UAVs is still developing and partly immature; however, improvements can be expected in the next decade.

The e-bomb targets mission essential electronic systems such as the computers used in data processing systems, communications systems, displays, industrial control applications, including road and rail signaling, and those embedded in military equipment, such as signal processors, electronic flight controls and digital engine control systems. I must point out that when e-bomb outputs are too weak to destroy these systems but strong enough to disrupt their operations, system performance can be degraded. The relation between the altitude (shown below) where the e-bomb is detonated and a representation of the lethality range. Target information (to include location and vulnerability) becomes an important issue.

E-Bomb – Science Fiction or a Fact?

Sor, can this hypothetical e-bomb be a significant weapon for the future battlefield? Theoratically, the military advantage obtainable with e-bombs is related mostly to their operational significance. Will future battlefields will be won by the countries that best manage the revolution in military affairs or technological revolution? If latter is the case, then one has to remind himself that technology is not a winner on its own, but it has been, and it will continue to be, a critical enabler. If everything else is equal, the side with better technology will win. Finally, can the country that first develops this new weapon have a significant and exploitable military advantage against other powers? Is is feasible for a nation to invest in this kind of bomb ? – The Debate Continues

As I have mentioned earlier, this piece is not research but infact just collection of some work, to explore the potential of EM technology in modern warfare as well as extending our previous discussion of Electronic Warfare For further reading about the subject I strongly suggest to read the following researches

Electronic Warfare Operations – Part I

O divine art of subtlety and secrecy! Through you we learn to be invisible, through you inaudible; and hence hold the enemy’s fate in our hands. – Sun Tzu (The Art of War)

Wedgetail Flares Test

The advant of technology and understanding the control of electronmagnetic specturm (EM) has taken the description of warfare to another level. Modern military forces rely heavily on a variety of complex, high technology, electronic offensive and defensive capabilities. EW is a specialized tool that enhances many air and space functions at multiple levels of conflict. Modern weapons and support systems employ radio, RADAR, infrared, laser, optical and electro-optical technologies. Modern military systems, such as the E-8C joint surveillance, target attack radar system (JSTARS), rely on access to the electromagnetic spectrum to accomplish their missions. So what exactly Electronic Warfare is?

EW is any military action involving the use of the EM spectrum to include directed energy (DE) to control the EM spectrum or to attack an enemy. This is not limited to radio or radar frequencies but includes IR, visible, ultraviolet, and other less used portions of the EM spectrum. As giving air and ground forces a superiority – the application of EW was seen in Operation Desert Storm (Gulf War) – Where self-protection, standoff, and escort jamming, and antiradiation attacks, significantly contributed to the Air Force’s success. Within the information operations (IO) construct, EW is an element of information warfare; more specifically, it is an element of offensive and defensive counterinformation. Electronic Warfare comprises of three main components: Electronic Attack – Electronic Protection – and finally Electronic Warfare Support, all includes the integrated Information Operations (IO).

Key to Electronic Warfare success is the control of Electromagnetic Spectrum Control. This is usually achieved by protecting friendly systems and attacking adversary systems. In reference to above mentioned three components of EW – Electronic Attack, limits adversary use of the electronic spectrum; – Electronic Protection – protects the use of the electronic spectrum for friendly forces, and Electronic Warfare Support – enables the commander’s accurate estimate of the situation in the operational area. All three must be carefully integrated to be effective. Friendly forces must prepare to operate in a nonpermissive EM environment and understand EW’s potential to increase force effectiveness.

Electronic Warfare for Air Forces

Air Force electronic warfare strategy embodies the art and science of employing military assets to improve operations through control of the EM spectrum. An effective EW strategy requires an integrated mix of passive, disruptive, and destructive systems to protect friendly weapon systems, components, and communications-electronics systems from the enemy’s threat systems. During the Gulf War, EF-111 RAVENS were used successfully against Iraqi radars and communications facilities. Conflicts in Vietnam and the Middle East provided deadly reminders of the necessity for effective EW against advanced threats and of the intense effort required to counter these threats. Current technology has given rise to new enemy capabilities, which includes the use of microwave and millimeter wave technologies, lasers, electro-optics, digital signal processing, and programmable and adaptable modes of operation.

Douglas B-66 Destroyer during Vietnam War

During the Vietnam War EB-66 was used against terminal threat radars, surface to air missiles (SAM) and anti aircraft artillery (AAA) as well as used as stand-off jamming platforms. EB-66 modified version of U.S light bomber B-66 Destroyer (shown above). The RB-66C was a specialized electronic reconnaissance and ECM aircraft with an expanded crew of seven, including additional electronics warfare experts. A total of 36 of these aircraft were built with the additional crew members housed in what was the camera/bomb bay of other variants. RB-66C aircraft had distinctive wingtip pods and were used in the vicinity of Cuba during the Cuban Missile Crisis and later over Vietnam. In 1966, these were redesignated EB-66C. After the retirement of B-66, General Dynamics/Grumman EF-111A (shown below) Raven came to play the role. EF-111A Raven was an electronic warfare aircraft designed to replace the obsolete B-66 Destroyer in the United States Air Force. Its crews and maintainers often called it the “Spark-Vark”, a play on the F-111’s “Aardvark” then nickname.

An EF-111A Raven aircraft supplies radar jamming support while enroute to Eglin Air Force Base during the multi-service Exercise SOLID SHIELD '87.

EF-111A achieved initial operational capability, in 1983 EF-111s first saw combat use with the 20th Tactical Fighter Wing at RAF Upper Heyford during Operation El Dorado Canyon in 1986 (retaliatory attack on Libya), Operation Just Cause in 1989. The EF-111A served in Operation Desert Storm in 1991. On 17 January 1991, a USAF EF-111 crew: Captain James Denton and Captain Brent Brandon (“Brandini”) archived an unofficial kill against an Iraqi Dassault Mirage F1, which they managed to maneuver into the ground, making it the only member of the F-111/FB-111/EF-111 family to achieve an aerial victory over another aircraft.

Operational Concepts

The effective application of electronic warfare in support of mission objectives is critical to the ability to find, fix, track, target, engage, and assess the adversary, while denying that adversary the same ability. Planners, operators, acquisition specialists, and others involved with Air Force EW must understand the technological advances and proliferation of threat systems in order to enable friendly use of the EM spectrum. To control is to dominate the EM spectrum, directly or indirectly, so that friendly forces may exploit or attack the adversary and protect themselves from exploitation or attack. Electronic warfare has offensive and defensive aspects that work in a “movecountermove” fashion. To exploit is to use the electromagnetic spectrum to the advantage of friendly forces. Friendly forces can use detection, denial, disruption, deception, and destruction in varying degrees to impede the adversary’s decision loop. For instance, one may use electromagnetic deception to convey misleading information to an enemy or use an enemy’s electromagnetic emissions to locate and identify the enemy. To enhance is to use EW as a force multiplier. Careful integration of EW into air and space operations will detect, deny, disrupt, deceive, or destroy enemy forces in varying degrees to enhance overall mission effectiveness. Through proper control and exploitation of the EM spectrum, EW functions as a force multiplier and improves the likelihood of mission success.

Billion Dollar Market For Electronic Warfare

Forecast International’s “The Market for Electronic Warfare Systems” projects an estimated $28.4 billion will be spent over the next 10 years on the development and production of the major EW systems. Some 44,807 units of leading Electronic Countermeasures (ECM), Radar Warning Receivers (RWRs), Electronic Support Measures (ESM), and other EW systems that make up this analysis will be produced. The top-ranked EW producers cited in the analysis (out of a total of 22 companies considered) are Northrop Grumman, BAE Systems, Raytheon, ITT, and Lockheed Martin. While production of leading missile countermeasures systems has helped position some of these companies at the top of the ranking, others are leading the development of all-important, next-generation technology. It is important to add that today’s EW market leaders are firmly established because of their ability to provide much-needed EW systems for immediate deployment to the battlefield. To cite just one example, despite some defense budget tightening, the Pentagon is expected to spend over $560 million through FY13 on procurement of Northrop Grumman’s Large Aircraft Infrared Countermeasures (LAIRCM) system for various Air Force aircraft. The service has declared that its long-range desire is to equip a total of 444 aircraft with the system. The market for systems to defeat improvised explosive devices (IEDs) will also warrant close monitoring in the years ahead. With the recent surge of U.S. troops into Afghanistan, there has also been an increase in the occurrence of IED attacks. To counter these attacks, a competition is currently under way for development of a Counter Radio-Controlled Improvised Explosive Device (RCIED) Electronic Warfare (CREW) 3.3 system of systems. The U.S. Naval Sea Systems Command in October 2009 awarded firm-fixed-price contracts to two companies for CREW 3.3 System of Systems development. ITT Force Protection Systems was awarded $16 million, while Northrop Grumman Space and Mission Systems, Network Communication Systems was awarded $24.3 million. International ventures will also have a significant impact on the EW market through the new decade. The primary platform for ITT’s ALQ-214 Radio Frequency Countermeasures (RFCM) system is the U.S. Navy’s F/A-18E/F Super Hornet. Through its association with the jet fighter, a potentially growing export market for the ALQ-214 has begun to emerge. For example, the system will equip the F/A-18Fs purchased by Australia a stopgap measure until its F-35 fleet is ready for service.

I will continue the implementation and integration of three major components of Electronic Warfare in my next post. Please do check back

Pakistan International Airlines – Losses Continue to Flow

Pakistan International Airlines (PIA)’s public relations team seemed to be very active this month. A month started with Russian airspace closure to PIA’s flights – The restriction came at a time when Russia had liberalised its airspace through historic relaxation of its airspace regulations. According to the sources, this was resulted due to PIA’s late move to airspace renewal on-time. Since, Russia is a quickest way to get to Europe, this move offcourse have serious implictaions on ill-fated PIA, who is already suffering badly when it comes to figures. The move will result in 15 to 20 minutes of extra flying time for most of the flights from Pakistan to Europe, the United States and Canada and back and increase the cost of flights. About 80 flights a week using Russian airspace for overflight will be affected.

Getting Figures Right

The state-run airline currently services domestic and international routes with a fleet of Boeing 777, Boeing 747, Airbus A310, Boeing 737 and ATR-42 aircraft. PIA suffered a loss of 135.8 million dollars in the first nine months of the year, according to its third-quarter financial report posted on the airline’s website. Accumulated losses stood at 88 billion rupees (one billion dollars). The national flag-carrier plans to induct 16 new aircrafts, lay off over 4,000 non-essential employees and double its revenue though aggressive marketing in the next five years. Ailing state carrier Pakistan International Airlines (PIA) is asking the government, saddled with its own mounting debt, to write off losses of 1.7 billion dollars to save it from looming bankruptcy – Now this is like putting an extra burden on billion dollar debt government.

Violation of airline safety conduct

PIA was created out of private airline Orient Airways in 1955, just eight years after Pakistan came into existence, and today has a fleet of 40 planes, a combination of Boeing 747s, 777s, 737s, Airbuses and ATR aircraft. Performing well until the 1970s when corruption and overstaffing hit company fortunes, PIA’s reputation was further battered in the 1980s as it failed to maintain its fleet. The airline recently imposed new rules to force pilots to fly on its terms, after a row over working hours and pension benefits led pilots to adopt an unofficial “go slow” protest leading to flight delays. Pilots said they were routinely forced to fly 12 hours per day, two hours more than the civil aviation rules allow, and occasionally for as long as 18 hours. Violation of airline safety conduct is something of a norm to PIA, but its not just PIA, the recent accident of Airblue also rasied the issue to retiring age of Captain and number of flights. To my knowledge of travelling with national flag, PIA operates B777, from New York to Karachi/Lahore – the route in past was operated by B747, who was used to make regular stops at Manchester to pick/drop passengers. This has not only reduced the operating life of the aircraft but also, cabin environemnt was no less than an attraction to newly board passengers like me, who see half of the cabin full of dead bodies. Excessive operation of used jumbos, resulted in 747 ban to European airspace, which finally resulted in grounding these plans. Now same routine is being adapted by B777. Worse of all, I have also travelled in PIA’s A310-300 who marginally meets the distance requirements of 3500 nautical miles distance between Manchester and Lahore.With 9 Boeing 777 in service (both long and extended range) why I had to travel on A310, I simply don’t know, may B777 were busy somewhere else. So far most of the planes operational in PIA including new 777 is active on conventional manual controls – some not even incorportaing the Glass Cockpit technology. Almost any new highly automated aircraft is brought down technologically by PIA engineers. Its not that PIA’s pilots aren’t interested in new technology, its PIA who is not bother to spend on training.

Enterprise Resources Planning (ERP) system

The national flag-carrier plans to induct 16 new aircrafts, lay off over 4,000 non-essential employees and double its revenue though aggressive marketing in the next five years. Under a five-year strategic programme, the PIA plans to acquire an Enterprise Resources Planning (ERP) system and implement it across the organisation to streamline business processes, strengthen controls and introduce financial discipline. An ERP is an integrated computer-based application used to manage internal and external resources including tangible assets, financial resources, materials and human resources. Under the programme, a sound system of internal controls will be established. The management is set to have a zero-tolerance policy for fraud and irregularities. A set of strategies will be implemented to turn around operations and make PIA a sustainable and profitable entity.Growth in revenue will be achieved through induction of new aircraft and expansion of the existing network. The airline also plans to pass on the increase in fuel prices to customers as it believes that the rapid escalation of airline expenditure in the recent past is mainly due to an unprecedented increase in fuel prices. Realising that retention of ageing 747 aircraft means continued increase in maintenance cost, the old aircraft will be phased out. Replacing the ageing 737 aircraft is a priority while the A310 aircraft will be replaced as and when financial resources allow investment. The 737NG or A320 are being considered as replacement. ATRs (short-haul European aircraft) will be acquired to increase frequency and capacity on socio-economic routes. It is planned to retain all types of 777 and ATRs in the fleet beyond 2014. During Haj season one 777 will be acquired on wet lease in each year from 2012 to 2014 when an A310 is also planned to be inducted into the fleet. Operational restructuring and human resource rationalisation is also part of the survival and turnaround plan as overstaffing is one of the PIA’s main problems which involves significant costs, clogs communications channels, diverts management’s attention from key airline issues and makes job responsibilities more obscure.

Enterprise Resources Planning (ERP) – if implemented it may serve the purpose, but I must point out that success of ERP implementation highly relies on investment in training (for IT personnel) as well as the coporate policy protection of the data, as well as controlling the way it is been used under ERP. I see this as a big transition, so big that I fear of the PIA implementation and data protection under ERP system. The blurring of company boundaries can cause problems in accountability, lines of responsibility, and employee morale. Furthermore, Once a system is established, switching costs are very high for any partner (reducing flexibility and strategic control at the corporate level).

Many have blamed privatisition and years of bad planning for the fate of PIA, it is actually the years of corruption, nepotism, bad management and poor planning, that is truely responsible for the loss the airline is suffering today.

The Buzz on China’s Drones

Chinease Ajain - Dark Sword

Since UAV (or Drones, as known to Asia Pacific) are very much in main-stream these days. So, I had to dedicate some more space within my blog to these unmannes vehicles. In an ongoing Chinease 8th International Airshow – Zhuhai 2010, Chinese commercial and defense aviation companies are exhibiting more than 25 UAV models. That is a record number of UAVs, according to show officials, and continuing evidence of China’s growing interest in unmanned technology. So Chinease are not only competing western industry for civilian or military jets, but UAVs also, as the show reveals. Some of the UAVs will serve as combat and battlefield reconnaissance roles. In one video, a UAV locates a U.S. aircraft carrier and relays the information for a follow-on attack by Chinese anti-ship missiles. Three Chinese companies – ASN Technology Group, China Aerospace Science and Industry Corp. (CASIC), and China Aerospace Science and Technology Corp. (CASC) produced most of the UAVs on display.

ASN Technology is the largest UAV production company in China, with a history of developing unmanned aerial platforms, including drones, since 1958, said a company press release. The primary customer is the Chinese military and the company controls more than 90 percent of the UAV market in China. ASN showed off 10 different UAVs, including the new ASN-211 Flapping Wing Aircraft System, which simulates a bird in flight. The prototype on display has a take-off weight of only 220 grams with a maximum speed of six-to-10 meters a second and an altitude ranging from 20-200 meters, primarily for low-altitude reconnaissance missions.

The largest UAV on display by the company was the ASN-229A Reconnaissance and Precise Attack UAV. Equipped with a satellite data link, it can perform aerial reconnaissance, battlefield surveys, target location and artillery fire adjustment during the day or night. It has a take-off weight of 800 kilograms and a cruising speed of 160-180 kilometers per hour with an endurance of 20 hours. Weighing in at 800 kg, ASN’s largest system was the armed ASN-229A Reconnaissance and Precise Attack UAV, which is still under development. Able to cruise at 180 km/h, the 5.5 m-long ASN-229A can perform reconnaissance, target location or artillery observation missions via a satellite data-link. Also among the 600 exhibitors were China Aerospace Science and Industry Corporation (CASIC) and China Aerospace Science and Technology Corporation (CASC). Both state-owned companies showcased sophisticated missile-armed UAVs. CASC displayed the CH-3 carrying two air-to-ground missiles akin to the AGM-114 Hellfire. This 640 kg medium-range craft with 220 km/h cruising speed is optimised for reconnaissance, intelligence gathering, artillery fire adjustment and electronic warfare, as well as the depicted attack platform.

CASC displayed the CH-3 multipurpose medium-range UAV system suitable for battlefield reconnaissance, artillery fire adjustment, data relay and electronic warfare. A company official said the CH-3 could be modified as an attack platform carrying small precision-guided weapons. Weapons outfitted on the display included two air-to-ground missiles similar in configuration to the U.S.-built Hellfire. CASIC took the prize for UAVs capable of intimidating the U.S. military. These included the jet-powered WJ-600. Aerospace Science and Industry Group, according to the material, WJ-600 can be mounted opto-electronic reconnaissance, synthetic aperture radar, electronic surveillance and other mission equipment, with fast response, and strong penetration ability, and can all-time effect of all-weather reconnaissance and damage assessmenttask, you can also load other types of equipment to achieve the task of ground attack, electronic warfare, information relay, and target simulation and other military tasks. Moreover, this means that WJ-600 drone is capable of trabelling faster than both U.S Predator and Reaper, currently opnerational in Afghanistan and Pakistan. The general speed of the UAV flying only about 30 m/s (58.3 knots), while the WJ-600 can be up to 200 m/s (389 knots – about 100knots greater than U.S MQ-9 Reaper who is equipped with turboprop engine), better on the flight altitude, up to ten thousand meters altitude – thanks to its jet engine. At this stage the project look rather ambitious

Other UAVs displays included a little-known company called Zhuhai X.Y. Aviation, which exhibited two new reconnaissance platforms, the 200-kilogram Blue Arrow (UR-J1-001) and 40 kilogram Sky Eyes (UR-C2-008). A company spokesperson said there were three prototypes of the Blue Arrow now being test-flown and that the prop-driven engine was from an unidentified “German company.”

Closing the UAV Gap

The recent display of 25 UAVs at the Zhuhai was not only the surprise for westeran but also flet by Japan, North and South Korea, and the Taiwanese officials.Drone technology, thus far, has been led by the U.S. and Israel. China now has UAVs that are comparable, although not equal, to the American Predator and Global Hawk. most of the ASN models in use by the Chinese military are older, more like the 1990s technology found in the U.S. Army Shadow 200 (now being replaced by the Predator-like, 1.2 ton Gray Eagle). One of the most numerous Chinese army models, the ASN-206/207, is a 222 kg (488 pound) aircraft, with a 50 kg (110 pound) payload. The 207 model has a max endurance of eight hours, but more common is an endurance of four hours. Max range from the control van is 150 kilometers and cruising speed is about 180 kilometers an hour. A UAV unit consists of one control van and 6-10 trucks, each carrying a UAV and its catapult launch equipment. The UAV lands via parachute, so the aircraft get banged up a lot. A UAV battalion, with ten aircraft, would not be able to provide round the clock surveillance for more than a week, at best. But Chinese planners believe this is adequate.

Sources suggests that many of the Chinese UAVs demonstrate an American influence, some appear to be using Israeli technology. That’s no accident, as four years ago, Israeli UAV manufacturer EMIT got busted after it was caught shipping UAV technology to China. EMIT was not a major player in the UAV industry, having only three models; the 450 kg Butterfly, 182 kg (400 pound) Blue Horizon, the 48 kg (hundred pound) Sparrow. The twenty year old firm has been scrambling to stay in business. The Chinese helped set up a phony cooperative deal in a Southeast Asian country, to provide cover for the transfer of EMIT UAV technology to China. Most of EMIT’s production is for export, but Israel has agreed to consult with the United States about transfers of technology to China. This is because Israel has been caught exporting military equipment, containing American technology, to China (in violation of agreements with the United States.) China tends to get technology wherever, and whenever, it can.

Chinease Xianglong

Two years ago, China revealed that it was developing a new UAV, similar to the U.S. RQ-4 Global Hawk. Called Xianglong (Soaring Dragon – shown above), it is about half the size of the Global Hawk (shown below), at 7.5 tons, with a 14.5 meter (45 foot) wingspan and a .65 ton payload. Max altitude will be 18.4 kilometers (57,000 feet) and range will be 7,000 kilometers. It has a faster cruising speed (750 kilometers an hour) than the RQ-4. The Chinese Xianglong is intended for maritime patrol, as is a U.S. Navy model of the RQ-4. The shorter range of the Xianglong is apparently attributable to the lower capabilities of the Chinese aircraft engine industry.

U.S Global Hawk

Interestingly, This year’s models in Zhuhai included several designed to fire missiles, and one powered by a jet engine, meaning it could in theory fly faster than the propeller-powered Predator and Reaper drones that the U.S. has used in Iraq, Afghanistan, and Pakistan. The large number of UAVs on display illustrates clearly that China is investing considerable time and money to develop drone technology, not only that the equation is equally balanced by promoting these products to international market. The implications of this is not only China’s internal security, also this is also an opportunity for nations alike China or Pakistan who have sought in vain to acquire drones either for military purposes or for police surveillance and antiterrorist operations. However, this is of particular concern to the U.S. and Israel, whose drones are unrivalled in the world today, and could worry China’s neighbors. A further details about Chinease buzz on drone technology can be read at the Wall Street Journal who has recently published a detailed resarch about the Chinease catch-up to U.S and Israel.
