Pero el F16 no lo fabricaba General Dynamics? O se lo han vendido a LM?

“Eurofighter Slays'Em!
I remember reading around two years ago about the prowess of Eurofighter over other aircraft. Well, this anecdote will probably ‘get out' one day and concerns the visit to these shores in July of Indian Air Force Su-30s. The MoD said that it would not be putting Typhoons up against them as a one-on-one fight. This is general knowledge. However '' it did happen and there is Head Up Display video to prove it. I don't know how it came about - probably during some exercise.
Anyway, two relatively inexperienced Typhoon pilots returned with big grins on their faces. The Sukhois were ‘toasted'. All the Su-30's air display antics came to nought - the Typhoons proved too nimble and too powerful for the Russian aircraft. The Typhoons were not ‘clean' either. You can check with the MoD, but you probably already know the kind of answer you'll get! (We did, and they wouldn't '' Editor).
The original article resulted in several letters of response about Typhoon versus the F-22. This cannot be confirmed or admitted officially, but during Typhoon's visit to the USA in 2005, both aircraft were pitted against each other (unofficially, you understand). The F-22 could not be seen by the Typhoon pilot, but his electronic counter measures showed him that it was being ‘painted' by his opponent. The Typhoon took appropriate ‘measures' using self-defensive aids. But when it came to one-on-one combat, the Typhoon did the same kind of job as it did with the Sukhois. The F-22s could not ‘handle' Typhoon close in and the Yanks were shocked!
It did not all go Typhoon's way on this occasion but it was a sobering encounter for the Americans. Remember, on the F-22 much was sacrificed in terms of ‘fighter performance' for stealth.
The first part of this letter, regarding the Sukhois, I have from first-hand experience, through the second part - about the F-22s - has come to me through the Typhoon grapevine. Fascinating, isn't it? The Typhoon does appear to be a truly formidable machine '' a machine feared by ‘other' operators.

Through still a relatively immature platform, Typhoon has already proved to be a hard opponent to beat, so that when a two-seat trainer was bounced by two F-15s during an operational conversion sortie, the Typhoon pilot was easily able to outmanoeuvre his assailants and position himself for a simulated ‘kill' against both. More recently, there have been repeated reports that two RAF Typhoons deployed to the US for OEU trials work have been flying against the F-22 at NAS China Lake, and have performed better than was expected. There was little surprise that Typhoon, with its world-class agility and high off-boresight missile capability was able to dominate the ‘Within Visual Range' fight, but the aircraft did cause a surprise by getting a radar lock on the F-22 at a surprisingly long range. The F-22s reportedly cried off, claiming that they were ‘unstealthed' anyway, although the next day's scheduled two versus two BVR engagement was cancelled, and “the USAF decided that they didn't want to play anymoreâ€. When this incident was reported on a website frequented by front-line RAF aircrew a senior RAF officer urged an end to the conversation on security grounds.

DASS
The Defensive Aids Sub-System (DASS) is a highly modular system, based around five Radstone Technology PLC processors. It combines and integrates a suite of advanced broad-spectrum threat-warning systems, together with a state of the art active countermeasures suite. The initial austere ECM system will be replaced from Block 5. The later system is fully automated, automatically detecting, locating, identifying and prioritising threats, and then deploying the most appropriate countermeasures, in sequence or concurrently, according to the nature of the threat.
The DASS includes a fully integrated wideband radar warning receiver and electronic support measures (RWR / ESM) system, with a comprehensive (and rapidly upgradeable) threat library. The system uses antennas in the port wingtip fairing and in the fuselage to give 3600 (spherical) coverage around the aircraft, and covers a frequency range from less than 100 MHz to 10 GHz, and can categorise radars from their operating wavelength, pulse repetition, frequencies and patterns, and scan patterns.
The RWR / ESM systems share common processing with other elements and are capable of making quick searches for electromagnetic emitters, with a range in excess of 100 km (62 miles), locating them through sequential triangulation, giving angular accuracies of better than one degree. The ESM sub-system analyses any detected signals, identifying the emitters, categorising them before prioritising any threats, warning the pilot and cueing the ECM, (while also feeding data for sensor fusion). Emitters can be displayed on the moving map display, or on other multifunction display formats.
The ECM system is also fully integrated with the ESM, with the same 3600 coverage around the aircraft and with the same frequency coverage. The system employs on-board and off-board jamming, and incorporates chaff and flare dispensers. The active jamming element of the ECM system is accommodated in the port wingtip pod, with RWR / ESM antennas on front and back, while the starboard pod accommodates an Elettronica-developed deception jammer module called ‘Cross Eye' in the Italian aircraft, and two expendable towed radar decoys (based on the Marconi Ariel) in the RAF aircraft. There is an RWR / ESM antenna on the front of the right wingtip pod.
Towed Decoys
The Decoys are towed on the end of a 100-m (328-ft) Kevlar cable which includes a fibre-optic link to the onboard signal generator, and can be deployed and towed at supersonic speeds. The starboard wingtip pod can be configured to carry Cross Eye and a single towed radar decoy.
A set of missile approach warning system (MAWS) sensors (based on the GEC-Plessey PVS2000 MAWS and using pulse Doppler millimetre-wave radar technology), are mounted on the wing leading edges and tailcone. A passive missile warning system is reportedly under study. From Block 5, RAF Eurofighters also have a laser-warning sensor, developed by Selex Sensors and Airborne Systems Ltd. Three sensors will be fitted, one on each side of the front fuselage.
Typhoon is fitted with two Elettronica Aster SpA chaff / flare dispensers in the inboard actuator fairings. These each carry 16 55-mm IR decoy-flares. Two Saab-Tech AB BOL 180-round chaff / flare dispensers are mounted on the outboard underwing missile launch rails. These countermeasures are deployed automatically by the DASS system, using one of many pre-programmed sequences, and chaff can be illuminated by the active-jamming system to increase its effectiveness, when it is colloquially knows as ‘jaff'.
