The AWE&C phased array radar replaces the conventional rotodome radar. It is mounted either on the aircraft fuselage or on top of the aircraft inside a stationary dome, providing full 360° coverage. This electronically steered beam radar delivers a tremendous advantage over mechanical rotating antenna, as it supports the tracking a high maneuvering targets. The radar can detect even low flying objects from distances of hundreds of kilometers, day and night, under all weather conditions. Verification beams sent at specific, individual, newly detected targets eliminate false alarms. Moreover, track initiation is achieved in 2 to 4 seconds as compared to 20 to 40 seconds with a rotodome radar The IFF system employs solid state phased array technology to perform interrogation, decoding, target detection and tracking. A monopulse technique is used to implement azimuth measurement. The IFF data is automatically correlated with the phased array radar. The ESM/ELINT system receives, analyzes and locates radar signals, covering 360o. It combines high sensitivity with high probability of intercept, and achieves excellent accuracy in bearing measurement. The system uses narrow-band super-heterodyne receivers and wide-band instantaneous frequency measurement (IFM) techniques to provide very high accuracy and probability of intercept of airborne and surface emitters. Very high bearing accuracy for all received signals is achieved through Differential Time of Arrival (DTOA) measurements. The system also collects and analyzes ELINT data. The PHALCON's CSM/COMINT receives in UHF, VHF and HF, rapidly searching for airborne, shipborne or ground communications signals of interest. Selected radio nets can be monitored for signal activity. A DF capability locates targets. Detected signals can be assigned to monitoring receivers instantaneously. The system makes extensive use of computers to reduce the load on operators.

IAI, EADS discuss adapting A320 for airborne early warning

By Stephen Trimble

Israel Aerospace Industries and EADS are in advanced discussions on teaming up to offer an airborne early warning system installed on a member of the Airbus A320 family, an IAI official says.

The discussions come after a series of overtures by IAI to adapt Elta Systems' conformal AEW technology to the A320 family.

EADS's Military Aircraft division previously rejected the concept, says Baruch Reshef, deputy director of Elta's group marketing and sales division. But its attitude has recently changed. "They are in favour of co-operation if we can find solutions that fit their platforms," he says.

IAI and EADS officials see a huge market opportunity for AEW technology, Reshef says, amounting to more than $10 billion over the next five years. IAI expects that an A320-based system could capture 30-40% of the market share, he says.

The first such A320 AEW platform could be available for service entry within three to four years of a contract award, Reshef says. The installation process "would be quite short in comparison to other programmes", he adds.

If both sides agree, IAI would help expand Airbus's portfolio of military offerings, which include the A330-based multirole tanker transport, A400M airlifter and a previous offer to provide adapted A320s for NATO's alliance ground surveillance programme - a capability which has subsequently been narrowed to include only unmanned aircraft. IAI would also gain a new platform for its conformal AEW technology, already installed on the Gulfstream G550 business jet for Israel and Singapore.

EADS declined to comment on the report, following a request from Flight International.

An A320-based system would join other Western market offerings in the airborne early warning and control segment, which include the Boeing 737, Northrop Grumman E-2D Advanced Hawkeye and Saab Microwave Systems' Erieye radar, which has so far been integrated with the Embraer ERJ-145 regional jet and Saab 340 and Saab 2000 turboprops.

IAI's Phalcon series of AEW radars began with the EL/M-2075 L-band electronically scanned array, first installed on the Boeing 707 for Israel and Chile. India has also acquired the radar for installation on the Ilyushin Il-76 transport.

Lockheed EC-130V Hercules


The Lockheed Martin EC-130V Hercules AEW&C aircraft was first developed for the United States Coast Guard as a proof of concept aircraft in 1992 by the General Dynamics company. As with the P-3 AEW, the EC-130V combined a C-130H airframe with the APS-125 Radar and Mission System of the US Navy Hawkeye. This aircraft was for counter-narcotics missions requiring greater endurance than the E-2 could provide, but has also been evaluated for Search and Rescue, Fisheries Patrols, EEZ enforcement and as a support aircraft for NASA Space Shuttle launches. Externally the EC-130 differs from a standard Coast Guard C-130 with the fitting of a large rotodome housing the APS-125 radar. Internally the mission system is palletized and was rolled into the C-130 cargo bay to complete the conversion (right). Due to budget cuts the Coast Guard, the EC-130V program was terminated and the EC-130V was transferred to the USAF as the NC-130H for further development including upgrading to the latest APS-145 Radar.
Lockheed Martin and the USAF have taken the concept further and are now considering a version based on the latest C-130J Hercules II for Foreign Military Sales.
The C-130J-30 AEW&C is based on the stretched variant of the Lockheed C-130J Hercules II, which features a new engine and propeller combination and digital flight station for two pilots. The C-130J-30 AEW&C is fitted with the AN/APS-145 on pylons above the rear fuselage of the aircraft. A tactical command centre and crew rest module is fitted into the cargo compartment to contain seven operator consoles and the Northrop Grumman (ESID) Group II+ mission system derived from the E-2C Hawkeye. Lockheed Martin have teamed with Northrop Grumman (ESID) and Transfield Defence Systems of Australia for the C-130J AEW&C.

Lockheed Martin Awarded $171 Million For Advanced Hawkeye Airborne Early Warning Radars

SYRACUSE, NY, March 4th, 2010 -- Lockheed Martin [NYSE: LMT] received a low-rate initial production contract valued at $171.8 million from Northrop Grumman Aerospace Systems in Bethpage, NY, for four AN/APY-9 Airborne Early Warning (AEW) radar systems and spare parts. The radar systems will be integrated into the U.S. Navy’s new E-2D Advanced Hawkeye aircraft.

“The APY-9 radar will provide unprecedented capability to the U.S. Navy and allied forces operating in the littorals to detect and track airborne and cruise missile threats,” said Carl Bannar, vice president and general manager of Lockheed Martin’s Radar Systems business, headquartered in Syracuse, NY. “This radar represents a two-generation leap in AEW capability.”

Designed and developed by Lockheed Martin, the AN/APY-9 radar features both a solid-state transmitter with higher power than its predecessor for extended range, as well as digital receivers to increase sensitivity. The UHF radar can “see” smaller targets -- and more of them -- at a greater range, particularly in coastal regions and over land. Its electronically scanned array provides critically important, continuous 360-degree coverage. As a new capability, flight operators also can now focus the radar on select areas of interest.

Two engineering-development models and four pre-production radar systems are currently in flight and qualification testing. Over the last several months, the Navy/Industry integrated test team has flown more than 230 radar flights, performing multiple hours of over-water, near-land and over-land radar operations. Mission system and radar-related testing are currently ahead of schedule.

“We are pleased with the radar’s detection performance,” said Dr. Doug Reep, Lockheed Martin’s program management director for AEW Radar. “Software updates are being released as scheduled and, with each release, the radar has demonstrated improved stability and performance during flight tests. We are confident we will meet the challenges of the Initial Operational Test and Evaluation scheduled to begin at the first quarter fiscal year 2012.”

Lockheed Martin will produce AN/APY-9 radars to equip all 75 planned U.S. Navy E-2D Advanced Hawkeye aircraft. Lockheed Martin has produced several generations of AEW radars for the aircraft over four decades. Lockheed Martin’s AN/APS-145 airborne radar is currently aboard in-service E-2C Hawkeyes and Hawkeye 2000 aircraft.

Israeli air force showcases G550 surveillance fleet
By Arie Egozi

The Israeli air force has for the first time discussed the activities of a new surveillance squadron that operates a fleet of heavily modified Gulfstream G550s from Nevatim air base in the south of the country.

Now acting as the "eyes and ears" of the Israeli defence forces on an almost daily basis, the "Nachshon" squadron operates under a heavy security blanket, but Flight International correspondent Arie Egozi was recently invited to visit the unit.

Over the years, the air force has used versions of transports including the Douglas DC-3, Israel Aerospace Industries Arava and Boeing 707 for missions such as airborne early warning and electronic intelligence-gathering. But faced with more sophisticated threats, the service several years ago decided to upgrade its capabilities.

It wanted something smaller and cheaper, but with much more capability than legacy systems. With the understanding that some equipment cannot be purchased on the open market, Israel's own advanced technology and determined people were called upon to deliver a cutting-edge surveillance capability.



Air force commanders held a series of long meetings with engineers from IAI, before hearing the phrase that they had waited for: "This can be done." The result was a programme to develop two special-mission variants from the G550: a business jet designed for people that have money but not time.

A visit in the passenger cabin of such an aircraft leaves a smell of fine leather in the nose and an impression of super luxury, but it was the model's other advantages of long range and high speed that formed the basis for its selection for military use.

The G550's transformation into an air force asset was not a simple task, but today Israel is operating the type in two adapted versions: the "Eitam" AEW aircraft and the "Shavit" ELINT platform. Both are equipped with technologies developed and manufactured by IAI's radar and electronic warfare subsidiary Elta Systems.

MULTI-SENSOR SUITE

For the AEW mission, the Eitam carries the company's EL/W-2085 multi-sensor suite, which comprises four conformal L- and S-band radars, plus communication and electronic support measures, communications intelligence and ELINT capabilities and identification friend-or-foe equipment, plus various other antennas mounted on the fuselage.

Surveillance data gathered by these on-board sensors is fused and continuously cross-correlated, enabling the suite to be automatically cued to search for specific targets, up to full 360° coverage.

The AEW radar uses four main active electronically scanned array antennas for wide-area coverage and to allow an instantaneous focus to be made on selected targets of interest. Elta says the radar can be pointed at any direction at any time, with the parameters of its arrays controlled by computer. As a result, surveillance can be limited to a battle zone and other areas of interest using a much higher scan rate.

A special mode for manoeuvring and high-value targets also employs a high scan rate, with beam shapes optimised to ensure tracking performance and extended detection range. Verification beams are sent towards specific, individual and newly detected targets, eliminating false alarms, says Elta. Track initiation is achieved in 2-4s.

Visiting such a highly classified air force squadron creates a big problem for a journalist, as it is obvious that it has already been involved in all sorts of operations that will stay under security wraps for years to come.

Questions about the Nachshon unit's operations to date were met with a polite smile, but its commander, a Lt Col, eventually commented: "We can operate at any range needed to defend the security of Israel."

The data sheet for the G550 lists the business jet as having a range of 12,500km (6,750nm) and an endurance of 11h, and IAI has previously said that the Eitam can fly for over 9h above 41,000ft (12,500m).

Asked whether the squadron has performed missions across such an envelope, the commander's smile appeared again, but no details followed.

The international media has claimed that Israel launched air strikes last year to destroy a secret nuclear reactor in Syria and convoys carrying arms in Sudan before they reached Hamas militants in the Gaza strip. Asked whether his unit was involved, not even the smile remained.

Climbing aboard one of the air force's G550s inside a brand new hangar at Nevatim delivers a sharp contrast to memories of business jets and champagne. Now equipped with its radar equipment and conformal antennas on each side of its fuselage, the modified Eitam is a windowless aircraft.

Asked whether a sense of claustrophobia or suffocation can be felt during long missions, Maj G - one of the aircraft's on-board mission commanders - says it was considered a potential problem before the aircraft entered operational use. But the need to fully concentrate on the images being shown on the mission system's large screens very quickly becomes the only dominant sensation, he says.

Squadron personnel worked very closely with Elta's engineers and technicians to design a system that would provide the best performance, and the aircraft's six air controllers sit in the aft section, behind a small galley in the centre of the cabin.

And while all signs of the luxury normally associated with the civil G550 have been eliminated, one special comfort has been provided. The controllers' seats have been covered with a special fabric, which gives them "a more fresh and easy felling", another squadron officer says.

Although the AEW aircraft attracts the highest profile attention, the air force's ELINT-configured Shavit also delivers outstanding capabilities. Going inside the aircraft, which has also been packed with sensors, was not allowed, but sources say the new asset has "completely changed the way in which Israel is able to build the threat picture from far away".

In common with the Eitam, the ELINT aircraft carries a comprehensive self-protection system that is operated according to the known threats that it may encounter on operations. "We are very well protected," the squadron commander notes.

Now fully operational, the air force's Nachshon squadron is delivering strategic capabilities that in the past were only on Israel's wishlist. IAI has already delivered its first AEW-configured G550 to launch export customer Singapore, and views India as another near-term sales opportunity for the type.

Y a comme un air de ressemblance entre le Shavit et le AML de L.M.

China’s Eyes in the Skies

The recent deployment of China's first four indigenous KJ-2000 AWACS aircraft marks an important milestone in the PLA Air Force’s long march from being a ‘numbers intensive’ low technology force, to a much more modern high technology one.

More fundamentally, though, the AWACS (Airborne Warning and Control System) extends China's deep and broad network of air defence Command Control Communications Intelligence Surveillance Reconnaissance (C3ISR) systems into a key airborne area. In doing so, China is now acquiring the radar and passive early warning and air defence command, control and communications it needs to counter foreign fighters and cruise missiles.

Yet despite the fact that this system employs radar technology two generations ahead of that used by the US Air Force’s E-3C AWACS—generally seen as a benchmark by the rest of the world—the deployment of China’s new aircraft elicited almost no response from Washington.

Airborne C3ISR systems such as AWACS aircraft typically operate as extensions to ground-based networks of air defence radar systems and defensive Surface to Air Missile (SAM) batteries, providing forward coverage against targets that are hidden from ground-based sensors by ‘terrain shadowing’ or the earth’s curvature. Such targets can be low-flying combat aircraft, but in an increasing number of cases are likely to be low-flying cruise missiles.

So, how important a step is this new system for China? To better understand the implications, it’s useful to look at the evolution of China's air defence capabilities more generally.

During the 1950s, the Soviets exported a range of air defence equipment to China, much of which reflected what was then state-of-the-art Soviet radar technology. But the Khrushchev-era tensions put an end to that, and over time China proceeded to reverse engineer all of these Soviet designs.

By the 1970s, China was producing clones or derivatives of most of this equipment, especially ‘acquisition’ radars designed to search for aircraft that could then be targeted by SAM batteries or interceptor aircraft. This area of military technology was so valued by the PLA that in 1969 it had initiated development of an indigenous AWACS—the KJ-1. This radar design was built into a 1950s Tupolev Tu-4 Bull aircraft which itself was a reverse engineered Boeing B-29 Superfortress. This project was repeatedly disrupted by the unstable political environment, and never produced an operational capability. Still, the efforts highlight the PLA’s long-standing interest in having credible airborne C3ISR.

Airbus Military C295 AWACS: Will It Take Off?



Airbus Military as early as next month could be flying a C295 prototype modified for use as an airborne early warning and control system following a self-funded technology assessment effort.

Three months of flight testing are planned, says Miguel-Angel Morrell Fuentes, Airbus Military Head of Engineering.

It is a crowded market, but Airbus hopes that the operating cost benefits for the C295 will help it secure customers.

The feasibility study was launched in the second half of last year and concluded around year end, before a decision was taken to build the prototype.

The dummy rotodome was installed on the C295 on May 17. It measures around 6 meters in diameter. Airbus Military has opted for a rotodome because it provides better performance with 360 deg. coverage, Morrell says.

Flight testing will look at the drag effects of the radar.

No specific radar has been selected at this point. Those decisions would not be made until the company decides to actually launch a program. The engineering assessment of flight testing first needs to be completed.

First Airbus Military C295 with AEW&C rotodome completes maiden flight


The first Airbus Military C295 development aircraft fitted with an Airbone Early Warning sand Command (AEW&C) rotodome has successfully completed its first flight on 7th June 2011 at Airbus Military’s site in Seville (Spain).

The flight follows extensive research and development work, including wind tunnel testing, leading to the conversion of a C295 to be fitted with the in-house developed rotodome.

The aircraft took off at 17h16 local time (15h16 UTC) and landed at 20h04 local time (18h04 UTC), after a flight lasting 2h48 (wheels off – wheels down). The experimental test pilot Alejandro Madurga captained the flight together with co-pilot Alfonso de Castro, the Flight Test Engineer Juan José Baeza, and the Test Flight Engineer Antonio Ojeda.

The objective of the trials is to verify the aerodynamic and structural impact of the rotodome on the aircraft’s overall structure, handling qualities and performance. The six metre diameter rotodome fitted for the initial trials is a fixed dummy structure. On production aircraft the rotodome would be a fast-rotating device housing a state-of-the-art radar providing full 360 degree and continuous coverage of a selected area.

“This first flight confirmed to us that the C295 is an excellent platform to support such a rotodome”, said Alejandro Maurga after the flight. The behavior of the aircraft and its flying characteristics were very satisfactory and as expected”.

Flight testing will continue during the next three months to complete the feasibility study and fully validate the concept.

Airbus Military’s C295 is an ideal platform for Airborne Early Warning and Control (AEW&C) missions. The C295 is currently used for other Intelligence, Surveillance & Reconnaissance applications such as maritime patrol, anti-submarine warfare or environmental protection missions, to list just a few. The C295 is a simple but robust platform with proven reliability, used in conflict operations for defence and homeland security missions. It is adaptable to the AEW&C role thanks to its versatility and the largest cabin in its class. The in-house developed Fully Integrated Tactical System (FITS) enables the integration of on-board sensors, including operation and monitoring of the future radar system and display of the
aerial picture.

The current AEW&C trials are to demonstrate the C295’s capability in this sector and thereby expand its range of applications. With the C295, Airbus Military has the tool to open up a new market segment for affordable high-performance AEW&C systems

The C295

The new generation C295 is the ideal aircraft for military transport and civic missions such as humanitarian aid, homeland security, maritime patrol, and environmental surveillance. Thanks to its robustness and reliability, and with simple systems, this medium sized tactical airlifter provides the wide versatility and flexibility required for personnel, troop and bulky/palletized cargo transportation, casualty evacuation, communication and logistic duties, or certified air-dropping capabilities. It is fitted with both civil and military technology equipment which ensures success on demanding tactical missions, as well as growth potential for future equipment installation, and compatibility with the latest civil airspace environment. The 295 is part of Airbus Military’s family of light and medium airlifters which also includes the smaller C212 and CN235 platforms.

Russia to develop new AWACS plane


Russia hopes to develop a new airborne warning and control system (AWACS) plane by 2016, Air Force chief Col. Gen Alexander Zelin said on Tuesday.

“We are expecting to receive the A-100 aircraft built on the basis of the Il-476 transport plane with the PS-90 engine and extended flight range,” Zelin told reporters in Moscow.

The new AWACS plane will have an advanced active phase array capable of detecting and tracking airborne and land-based targets.

“We will have the carrier [Il-476] by 2013-2014 and should be able to build this plane by 2016,” Zelin said.

The Russian Air Force has around 20 A-50 Mainstay AWACS planes, based on the Ilyushin Il-76 transport.

The A-50 is equipped with the large Liana surveillance radar with its antenna in an over-fuselage rotodome and can control up to ten fighter aircraft for either air-to-air intercept or air-to-ground attack missions.
