Northrop Grumman's Scalable Agile Beam Radar (SABR) Successfully Demonstrated Aboard U.S. Air Force F-16

January 25, 2010: 04:36 PM ET


LINTHICUM, Md., Jan. 25, 2010 (GLOBE NEWSWIRE) -- Northrop Grumman Corporation (NYSE:NOC), in conjunction with the U.S. Air Force, has successfully completed a series of demonstration flights of its Scalable Agile Beam Radar (SABR) installed in an F-16 fighter aircraft at Edwards Air Force Base, Calif. The demonstration was in support of a U.S. Air Force F-16 Active Electronically Scanned Array (AESA) feasibility study.Â
"Almost two years ago Northrop Grumman said that air forces of the future will necessarily gravitate toward using AESA technology – especially through scalable retrofit technology. Our team has worked diligently to make that possible and today we've made it a reality. This officially marks the first time a retrofit AESA has ever flown in a legacy F-16," said Arlene Camp, director of Advanced F-16 Radar Programs at Northrop Grumman's Electronic Systems sector.Â
"This demonstration validated our goal of developing an AESA that can be easily installed on the flight line and integrated with existing power and cooling provisions of currently fielded F-16s," Camp added. "With regard to installed performance, SABR's air-to-air and air-to-ground detection and tracking and Synthetic Aperture Radar (SAR) mapping performance met or exceeded our predictions."  Â
SABR is an affordable and scalable AESA radar designed for retrofit in current F-16s and other legacy fighter, attack, and training aircraft. Compared to mechanically-scanned array radars, SABR will provide the increased performance, multi-functionality, and greater reliability inherent in AESA radars. In terms of combat capability, SABR provides improved situational awareness, greater detection, high-resolution SAR maps, interleaved air-to-air and air-to-surface mode operations, and an all-environment precision strike capability.
Northrop Grumman has been the sole provider of radars for the F-16 and for over 30 years has continually improved the F-16 radar's performance and reliability. More than 5,000 F-16 radars have been produced for the U.S. Air Force and 24 nations worldwide.Â
Because of this extensive foundation and rich F-16 heritage and platform intimacy, Northrop Grumman is the first to design, develop, integrate, test and successfully demonstrate retrofit AESA capability in flight on a legacy F-16. Â SABR is part of Northrop Grumman's robust product family of multi-function sensors and capabilities.

Elta buoyed by new aerostat-radar contract
By Arie Egozi

Israel Aerospace Industries' Elta Systems division has received a $57 million contract from an undisclosed foreign customer to supply aerostat-housed EL/M-2083 long-range airborne early warning radars.

Surface-based radars have limited line of sight to detect low-flying threats, such as manned and unmanned aircraft and cruise missiles, and the tethered aerostat-carried systems are used to "fill the gap".

In recent years, Elta has supplied its balloon-carried radar systems to several countries, including India.

Once deployed at an altitude of up to 13,000ft (3,960m), the EL/M-2083 is capable of providing 3D coverage over a radius of 500-600km (270-325nm).

Elta's EL/M-2083 is derived from the company's L-band EL/M-2080 "Green Pine" ground-based fire-control radar, which forms part of Israel's Arrow ballistic missile defence system.

Northrop Grumman expects USAF decision on F-16 radar upgrade soon
By Stephen Trimble

Northrop Grumman expects the final word from the US Air Force on a possible radar upgrade for its Lockheed Martin F-16s within a few months.

Northrop has developed and tested the scaleable agile beam radar (SABR) to compete with the Raytheon advanced combat radar (RACR) for the contract.

Both companies invested in active electronically scanned array technology for the F-16 with the expectation of USAF orders, but the service has not yet confirmed an approved need or funding to upgrade the mechanically scanned Northrop APG-68.

"We have been anticipating something out of these guys for the last couple of months and it's still right on the edge of their tongue," says Dave Wallace, Northrop manager for F-16 sensor programme development. "We'd be expecting to see something early next year, if not sooner."

SABR scaleable agile beam radar

Northrop installed SABR on an F-16 Block 50 last year. Flight tests demonstrated the air-to-air mode and a range of broad and narrow modes within the air-to-ground synthetic aperture radar mode, says Wallace.

USAF officials recommended making changes to the pilot vehicle interface, which Northrop has done, he adds.

Raytheon disclosed recently that it had completed tests on the same F-16 in July and August, and expects to submit its findings to the USAF this month.

Both companies have invested heavily in the F-16 radar retrofit programme ahead of a customer commitment. The USAF has been conducting a service life assessment programme on the F-16 fleet to determine how long the aircraft will remain viable.

"I think the air force is looking to extend the capability and life of its airplanes," says Wallace.

While Raytheon touts the RACR's links to the APG-79 AESA installed on the Boeing F/A-18E/F Super Hornet, Northrop traces the SABR architecture to the APG-80 agile beam radar on the F-16 Block 60 and the APG-81 on Lockheed's F-35 Joint Strike Fighter.

"We will update SABR with everything the F-35 gets," says Wallace. "If you update the F-35, and [if] the F-16 needs an update as well, essentially all you do is host it on the F-16 architecture and test it, and we are arranging for that to work."

The USAF decision could also influence the foreign market. Northrop and Raytheon have received US export licences to market the F-16 AESA products to foreign militaries. Wallace adds: "It's tough to determine whether or not they would go before a US Air Force decision has been made. If I had to handicap, at best it's simultaneous."

Raytheon Flies New Advanced Combat Radar on F-16

EL SEGUNDO, Calif., Dec. 2, 2010 /PRNewswire/ -- Raytheon Company's (NYSE: RTN) Advanced Combat Radar, the latest Active Electronically Scanned Array radar, has successfully completed a series of flight trials on a U.S. Air Force F-16 at Edwards Air Force Base, Calif.

The radar demonstration flights were conducted in partnership with the U.S. Air Force and Lockheed Martin. The RACR team highlighted the multirole capabilities RACR could bring to the F-16 Fighting Falcon, which included executing a range of air-to-air and air-to-ground modes.

RACR is the product of company-funded development, leveraging Raytheon's proven capability in providing active electronically scanned array radar technology for multiple platforms. The RACR team completed development in a record 24 months.

"AESA radar technology has become a 'must have' for customers around the world who need to keep their aircraft relevant in the swiftly evolving battlespace," said Jim Hvizd, vice president, international business development, Raytheon Space and Airborne Systems. "Successfully flying RACR on an F-16 is another critical step in demonstrating how we've optimized our AESA technology for F-16 customers, delivering the advanced radar capabilities they need to maintain an operational edge.

"Raytheon's AESA technology also lowers operation and support costs by an order of magnitude compared with those of mechanically scanned radars, resulting in significant customer savings over the life of a program," added Hvizd.

RACR is part of a family of Raytheon AESA radar systems designed to equip multiple aircraft with a low-risk, high-performance, affordable solution. The radar supports a rapid transition to production, leveraging Raytheon's existing full-rate AESA production lines, providing significant cost and schedule advantages for customers.

"Raytheon's AESA technology brings unparalleled capability and reliability to the F-16 at an acquisition cost comparable to the old mechanically scanned radars," said Brian MacDonald, RACR program manager, Raytheon's Tactical Airborne Systems. "RACR is now available as an option for domestic and international customers. We have designed, built and matured RACR from concept through to F-16 flight demonstration to ensure we can support any customer delivery time frames for new or retrofit aircraft requirements."

Raytheon, Northrop Grumman take opposite paths on F-16 AESA sales
By Stephen Trimble

As rivals in a race to open an international market for retrofitting active electronically scanned array (AESA) radars on Lockheed Martin F-16s, Raytheon and Northrop Grumman are looking for customers in opposite locations.

The first customer for the Raytheon Advanced Combat Radar (RACR), which shares 90% commonality with the APG-79 AESA aboard the Boeing F/A-18E/F Super Hornet, may come from abroad, says Ken Murphy, a member of Raytheon's capture team.

"The international side realises they need to get out in front of the US [Air Force]," Murphy says. "We're hoping to see a [request for proposals] next year."

Murphy declines to cite specific countries, but Raytheon is known to have received export licenses to market RACR to Greece and South Korea.

Northrop Grumman, meanwhile, has predicted the US Air Force could move first. Last month, Dave Wallace, the company's manager for F-16 sensor programme development, said a USAF decision to launch an AESA-retrofit programme is "right on the edge of their tongue".

Northrop offers the Scaleable Agile Beam Radar (SABR), which is derived from the APG-81 on the Lockheed F-35 and APG-80 on the F-16 Block 60.

Both companies have now integrated their AESA candidates on an F-16.

Most recently, Raytheon completed six flights with the RACR installed on a USAF F-16. Murphy acknowledges the RACR schedule was accelerated for a demonstration programme. Raytheon skipped the traditional step of installing the radar on a testbed aircraft, with Northrop having previously tested its SABR on a company-owned business jet.

But, Murphy explains, RACR could be integrated quickly because of its commonality with the APG-79 and Raytheon's experience with retrofitting an AESA on F/A-18E/Fs.

In only six flights, Raytheon tested several modes on RACR, including aerial search and track, synthetic aperture radar and ground moving target indicator. The flights also showed that RACR could be integrated into the F-16's joint helmet mounted cueing system, allowing the pilot to cue the sensor with a head turn.

Murphy notes that such a system would prove ideal in a combat scenario on the Korean peninsula as a counter-artillery system.

"The capability that RACR brings would definitely help," he says. "Any type of AESA would be greatly needed and the capability it brings would be significant."

Cost of the RACR retrofit is comparable to that of upgrading the F-16C/D’s Northrop APG-68 mechanically scanned radar to the SAR-capable (V)9 standard, but the AESA offers a tenfold increase in reliability, Murphy says

Raytheon close to revealing first customer for upgraded AESA radar

Thursday, 23 June, 2011

Gareth Jennings Jane's Aviation Desk Editor
Le Bourget, Paris

Raytheon is poised to announce the first customer for its active electronically scanned array (AESA) radar upgrade for the Lockheed Martin F-16 Fighting Falcon and Boeing F/A-18C/D Hornet combat aircraft, a senior programme official told Jane's at the Paris Air Show.

Speaking on 22 June, Mark Kula, Vice President for Tactical Airborne Systems at Raytheon, said: "Within the year we hope to have some sort of go ahead on a production contract for RACR [Raytheon Advanced Combat Radar]."

Kula declined to specify which operators the company expected to sign up, except to say that "the most likely" first recipients of both the F-16 and F/A-18 radars would be Foreign Military Sales (FMS) customers. "We have active campaigns on both [aircraft types]," he said.

Jane's understands that the first customer may be either Taiwan or South Korea as they look to modernise their F-16 fleets, although Kula would not comment on this. He did, however, say that Raytheon is "not actively pursuing" offering the RACR as a radar solution for the Korean Aerospace Industries (KAI) FA-50 light attack aircraft.

In addition to potential FMS customers, Kula confirmed that the US Air Force (USAF) and US Navy (USN) are in discussions with the company regarding possible RACR upgrades to their F-16 and F/A-18C/D fleets respectively. Neither service has yet decided how they wish to proceed with their service-life extension programmes, however.

Derived from the AN/APG-79 AESA radar fitted to the Boeing F/A-18E/F Super Hornet and EA-18G Growler, the RACR is the only AESA system cleared for export by the US government.

Raytheon has identified a global market of about 2,000 legacy F-16 and F/A-18 aircraft that could benefit from a RACR retrofit.

un projet lié serait en carton pour le Ka-52K (navalisé),qui equipera les "Mistralski"(premier attendu en 2014)

ce Ka-52K devrait voir a 200km pour pouvoir utiliser les missiles Kh-31/kh-35,mais la problematique typiquement russe de miniaturisation presente un challenge pour le radar.

les radars Arbalet ont completé leur tests et rejoindront donc les chaines d eproduction des Ka-52 pour l´armée russe.

et ca pousse..et ca pousse..

DUBAI: Northrop eyes Mideast F-16 AESA market
By: Greg Waldron Dubai

Northrop Grumman sees significant opportunities for Active Electronic Scanned Array (AESA) radar upgrades for Lockheed Martin F-16 aircraft in both the UAE and the broader Middle East.

The US government is in discussions with the UAE to upgrade the APG-80 AESA radars installed in the country's fleet of about 80 F-16 Block 60s, said Skip Wagner, director of business development for global sensor solutions. He added that the USA has also discussed the possibility of providing APG-80s for a potential follow-on order of F-16 Block 60s.

Speaking with Flight Daily News at the Northrop Grumman chalet, Wagner estimated that there is a broader market to upgrade the radars of 400-500 F-16s operated by regional air forces in countries such as Egypt, Oman, Pakistan, and Jordan.

The market is not yet ripe, however. The US air force has yet to announce an AESA upgrade for its F-16s. Either South Korea or Taiwan could be the first movers in the F-16 AESA upgrade segment. In both countries, Northrop is pitching its Scalable Agile Beam Radar (SABR) and rival Raytheon its Raytheon Advanced Combat Radar (RACR).

The APG-80 operated by the UAE bears great similarity to the SABR. "Both are produced by the same people in the same factory," said Wagner.

je pense que le SABR n'a pas encore eu sa licence export
la concurrence sera serré avec Raytheon qui propose un produit je dirai plus ingénieux et qui résoud un peu les problèmes de scan latéral dont souffrent les Aesa en général, le RACR pourra être couplé au JHMCS le pilote pourra diriger le flux radar rien qu'en tournant la tête
