F-35 radar makes showing at electronic attack exercise

July 3, 2009 (by Eric L. Palmer) - Northrop Grumman Corporation has announced that it successfully demonstrated key electronic protection capabilities of the F-35 Lightning II's AN/APG-81 radar during the recent Northern Edge 2009 (NE09) joint military exercise.

The Northrop Grumman AN/APG-81 active electronically scanned array (AESA) radar was flown on board the company's BAC 1-11 test aircraft and was integrated into what is considered the United States' largest and most complex airborne electronic warfare (EW) exercise to date. Northrop Grumman demonstrated the electronic protection (EP) capabilities of the AN/APG-81, by successfully countering advanced electronic attacks (EA), which are intended to degrade, neutralize, or destroy friendly combat capability.

"This event represents a major milestone in electronic protection testing for the AN/APG-81 in an operationally representative environment. We have been able to prove a number of EP capabilities years ahead of normal development timelines," said Teri Marconi, vice president of Combat Avionics for Northrop Grumman Electronic Systems sector. "The AN/APG-81 is the world's most advanced fighter fire control radar. It has extremely robust electronic warfare capabilities, and these tests validate years of laboratory testing versus a wide array of threat systems."

"The radar was subjected to a scale of scenarios that far exceeded typical developmental or operational test program requirements," said Pete Bartos, a former U.S. Navy F/A-18 operational test director and currently Northrop Grumman program manager for fifth-generation fighter requirements, improvements and derivatives. "In the past, typical EP testing consisted of a few sorties versus a single or maybe two jammers at once. This test was unique in that it included flights versus multiple types of advanced jammers on several aircraft formations at once."

The AN/APG-81 radar is currently undergoing integrated avionics flight testing aboard the Lockheed Martin Cooperative Avionics Test Bed (CATBird) aircraft, and is being installed in production F-35s on the aircraft assembly line in Fort Worth, Texas. The AN/APG-81 is designed and produced by Northrop Grumman's Electronic Systems sector.

Northern Edge 2009 is a joint field training exercise incorporating over 9,000 warfighters supervised by the Joint Electronic Protection for Air Combat (JEPAC). NE09 provided an operationally representative training environment that integrated over a dozen types of U.S. fighter and bomber aircraft as well as an entire U.S. Navy carrier strike group. Large force air, land, and sea combat scenarios along with airborne interdiction of maritime target scenarios provided unparalleled opportunities for warfighters to 'train-as-they-fight' in a complex radio frequency environment.

Team members from JEPAC collaborated with the U.S. Air Force and Naval Warfare Centers as well as the military service research laboratories to present and integrate a realistic twenty-first century threat capabilities in NE09, effectively exposing over 700 aircrew service members to an unprecedented level of advanced electronic attack scenarios. This environment presented a rare and valuable opportunity to observe the performance of the F-35 Joint Strike Fighter's APG-81 radar.

The JEPAC is one of ten test projects under the Office of the Secretary of Defense-sponsored Joint Test and Evaluation (JT&E) Program that develops joint tactics techniques and procedures to improve combat effectiveness through the use of electronic protection via timely integration of specific target track generating capabilities with tactical shooters during combat employment through the use of enhanced testing methodologies such as Northern Edge. The NE09 exercise is approved by the Chairman, Joint Chiefs of Staff (CJCS); scheduled by the Commander, United States Pacific Command (USPACOM); and sponsored by the Alaskan Command (ALCOM).

Sounds good. I hope they have ways to make these things safe from other nations trying to take them apart and copying them?

They dont know about other's state of development and doesn't show anything more than what is feasable with a good AESA and a system like SPECTRA.

Really need the US cityzen dosh don't they?...

LOL.. Because Rafale's future AESA will be massively inferior





Posted in F-16 NET sometime ago..You must know who are you dealing with...






ý am new here and i just wanted to warn you:

Sampaix/fonck/gegene/thunder is the same guy and he is famous for trolling this kind of forums. He has been banned from ALL the forum he has posted. (even french forums). pprune, keypublishing, world's armed forces,eurofightertyphoonstarstreak.net , air défense.net...

he is always looking for places where he can argue that the rafale is the best...etc etc... I am french and i also love the rafale but i am an air enthousiast above all. sampaix/fonck/gegene/thunder is the kind of person who follows an endless war against all other competiting aircrafts. This behaviour is pretty puerile and i always wonder whether what is he doing of his life exept polluting forums like this one.

he tries to defend the rafale he is rafale worst threat on forum. even people who liked this aircraft before (with its qualities and flaws) tend to hate it.

Good way to describe him. I did like Rafale until he showed up.

SOURCE:Flight InternationalF-22 stealth coatings face legal scrutiny
By Stephen Trimble

A pending lawsuit by a Lockheed Martin-trained stealth expert may provide new perspective on concerns about the F-22's low observable, or stealth, systems.

Although no complaints about the F-22's ability to achieve its promised radar signature have surfaced in the public domain, there have been repeated issues with the safety and maintainability of the coatings that provide dissipate and absorb radar energy.

A recently unsealed, three-year-old legal case filed by Darrol Olsen, a former F-22 engineer, accuses Lockheed of knowingly using defective coatings for the F-22 in the mid-1990s, and covering up the problem by applying 272kg (600lb) worth of extra layers.

The Department of Justice declined an opportunity under the Fair Claims Act to pursue Olsen's case on the government's behalf. Olsen now plans to file an amended version of the unsealed complaint to the US District Court in California's central division.

In response to Olsen's allegations, Lockheed replied: "While we are aware of the Olsen lawsuit, the corporation has not yet been served in this matter. We deny Mr Olsen's allegations and will vigorously defend this matter if and when it is served."

Lockheed's use of coatings on the F-22 could come under court scrutiny


Olsen wants to be reinstated with back-pay plus interest since being fired by Lockheed more than a decade ago, says Samuel Boyd, Olsen's attorney.

Olsen is also asking the court to order Lockheed to pay the US government $50 million for each of the 183 F-22s currently ordered, says Boyd. That amount equates roughly to the cost of the allegedly compromised stealth technology on each jet.

Olsen began his Lockheed career in 1979 at Skunk Works, where he worked on developing new composite materials for the F-117, according to court documents. Olsen bounced between the F-117 and Northrop's B-2 programme during the 1980s, finally returning to support Northrop's B-2 flight test programme in 1990.

In 1995, Olsen finally joined Lockheed's materials and processes engineering group in Marietta, Georgia, to work on the low observables system for the F-22.

In 1998, Olsen claims he refused to participate in an award ceremony that falsely honoured his team for solving problems he knew still persisted.

Although Olsen was fired for "failure to follow instructions" in 1999, the lawsuit says, he believes the problems have never been fully addressed.

In March 2008, an F-22 sustained major damage after a small strip of stealth coating inside the engine nacelle peeled off and was ingested by the fan blades of the Pratt & Whitney F119 engine.

In November, John Young, who stepped down in May as undersecretary of defence for acquisition, technology and logistics, told reporters he was concerned about the F-22's stealth, or low observable, maintenance requirements.

"I would highlight in general the maintenance on the airplane is too high," Young said. "They're struggling with some of the LO and other issues, and there's clearly work that needs to be done there to make that airplane both capable and affordable to operate."

LOL!

NO wonder the US needs Europe to finance the F-35 programe, so what exactly do we have to ENVY to the US?

LOL are you serious? You shouldn't talk for Europe when it's clear other Europeans on this forum don't like/agree with you. If we are 'superioricists' then you must be a French demi-god? LOL

The fact that you really believe your own rhetoric is amazing no matter how many times you've been owned.

----------------------------------------------------------------------------------------

Keep you head where the sun never shines, it's NOT Europe which needs the US for technologic over-rated "Achievements" and developements it is the US.

US problems are well known starting with design and this habit to rush unfinished products in service while supporting them with solid gold and hiding their defects with tons of technico-commercial crap for trolls like yourself to read.

Obviously you CANT and WONT read the counter commercial stuff even so it is coming from the most serious sources including the US manufacturers themself.

Europe isn't the US, over here we make do with a fraction of the US R&D budget while aligning more performant materials simply because the effect of scale works with skills just as well, the US is in a skill crisis of an unknown amplitude in europe.

The crisis in the US side is a lot more acute but he, not everyone have the guts to reconise this expecially not Johny walker-W-E Keyboard warriors like yourself who have litte comprehension of what they write.

F-16.com? LOL!

The forum where "god-himself" pretended for years that 1.200 mph was an aerospacial measurement and was equivalent to M 1.8?

The place where they pretend that US aircrafts doesn't obbey to the same aerodynamic laws than everywhere else and that a structuraly milited 7.0g aircraft out-turns a 11 g one?

The one where they keep feeding boys like you with the false impression that 6 AAMs will cost 0.4 Mach to a Eurofighter Gripen or Rafale when they supercruise at M 1.2 with 4 of them plus a 1.250 l tank in the case opf a Rafale?

Oh yeah i forgot, the place where F-35 is out-performing a "clean" F-16 which were never "clean" because "they" changed the definition of the word by "with external tanks only".

Give us a break.

The fact that the local idiots chose to keep themself ignorant of Europe's reality doesn't make it desapear, nor is yours as rosy as you like to make it up.

Now read the article on US "superior" stealth technology and come back in 2012 when SNECMA will sell a 90 kN M88.

RBE2 is totaly capable of rivaling the US radars and the US aircraft manufacturers knows this too well already and BTW, France's ECMs and IR sensors technology impresses the US top brasses, NOT the opposite.

ROFL!!! DON'T start making sh*t up little kid k?

TELL me which technologies did the U.S NEED from europe after world war 2 up to this day? That's right, more like EUROPE needed from the U.S, we practically built your fvcking countries moron.

TELL me WHERE did France go for AESA tech? USA

TELL me where did France go to develope nuclear tech? USA

TELL me WHO helped build the major countries in EUROPE after WW2? USA

TELL me WHERE did France go to for advanced missile technologies? USA

TELL me who leads the world in science and technology STILL as of 2009? USA

I tried to ignore your ignorant and rampant trolling, i really don't see why you're even posting all you ever did for contribution to WAFF is TROLL. Go troll somewhere else retard.

Instead of thanking us for saving your asses 3 times in the past century, you to decide to act like the 8 yr old child you are.
