No they don’t read my full post, was not done

May i suggest you to ask Vianney Riller Jr? you can find him on facebook or twitter, he will answer you.
We are talking about two pieces of equipment who on their own cannot ID a target (type, track, etc) but through the close cooperation (this is why the fiber connection is required) can provide the appropriate ID/Track.
Which is exactly SPECTRA’s job…

Here, red symbol means highest pririty. Next target will be the mirage 2000 RDI situated 8 NMs behind. (in fact the shot was performed 20 NMs behind btw)
Oh, will publish soon fully legended SITAC of Rafale (including this one), both in french and in english 😉
What is new and unique was mentioned earlier in the discussion about DAS, targets are passed off from one sensor to another seamlessly on F-35 (theoretically). They are classified, given a symbol for pilots ID and tracked throughout battlespace. Pilot is aware of where friendlies and bogeys are in a potentially chaotic situation where a moments hesitation can kill you or at least limit your response time.
Which is exactly SPECTRA’s job…
Again, that is BASIC sensor fusion where each piece of equipment delivers a “track” to the central unit and that unit then merges tracks that it thinks are the same thing.
I am talking about where a piece of equipment (radar or ESM) does not have enough info, on it’s own, to identify or develop it’s own track and only through the very close & combined efforts of both the radar and ESM is a valid ID & track developed.
The exact way this happens is obviously classified, but that is the basic definition of the feature.
Which is not new and ot specific to F35. See Tragedac program for ex, raw data from sensors will be fused in a patrol (and not only tactical situations). I agree it is new in a US context as compared to “legacy” planes.
Dunno if these values from Crhis Yeoh test of Rafale with 3x2000L + 2 Scalp missiles + 4 AAM will bring something to chew for experts (‘im not). This is at 25000 feet
At a typical cruise speed of M0.82/347kt, the aircraft could sustain a 60º banked turn at maximum dry power. Slamming the throttle to maximum reheat and rolling quickly into a full stick-back hard turn to simulate a break away from a threat gave a rapid response, automatically limited initially to 18.8º alpha and 4g. As the turn progressed, the FCS allowed the incidence to increase to 19.2¼ alpha as the airspeed decayed. Again, I was impressed with how easy it was to extract the maximum performance from this heavily loaded aircraft.
Rolling back to wings-level flight, I re-engaged reheat for a level acceleration from M0.6 to M0.9 in 35s.
still genuinely asking about “pulse for pulse”, sry i’m not english born 😉
Lets be honest, F35 will be a great plane, within its originally intended role.
Without knowing the “exact” capabilities of the -239 I cannot say, only speculate based on its heritage.
However, I think it is the first ESM to work with the radar on a “pulse-for-pulse” basis.
Define pulse for pulse plz? Because i’m dubious
Key points:
“The importance of high aerodynamic performance in BVR combat, especially persistent supersonic cruise, appears least well understood in the West. It provides more kinetic energy to BVR missiles at launch, improving range, but also allows a fighter under attack to more easily escape from an opponent’s missile engagement envelope, no differently than in WVR combat. The latter underscores what Australian analyst Peter Goon terms the “BVR paradox”—the reality that modern BVR combat imposes higher performance demands on fighters than WVR combat does.”Amen
Very well understood by RAF, and one o the few points i’d give an edge for typhoon over RAfale (ouch, it hurts!)
Capes = Capabilities
The info that was “hacked” was non-classified info.
Wondering how ASQ-139 capes are exclusive? Genuinely interested.
Thanx .
Is there any possibility in India for Private companies both Foreign & Domestic to win Defense contracts given the fact that traditionally the Government of India has shown a bias towards Indian Government owned Defense companies ?
HAL leadership as integrator was stated in MMRCA RFP (NOT provider responsability). DAssault is only securing a second supply chain for subsystems
If it is ASQ-239 that he’s talking about, then he is right as long as the threat has 1980s technology (analog RWR, no modern IRST, no networking) and is actively participating in its own demise through profligate use of radar. ALR-94 and ASQ-239 capes are real, but get less exclusive every year.
Capes? Confused (english) could you explain please?
L1 bid is calculated based on lifecycle costs.
In fact it was calculated on life cycle + upgrades costs.
What could be described as dragging costs high is the cost ot ToT (training etc.) and industrialization costs (factories dont come for free)
ASQ-239 is only an enigma to those without the initiative to learn about its capabilities and why it costs more than all the other sensors.
Nothing more than what is already present on some eurocanard and will be present on Gripen NG… Discovering interferometry? :applause:
(half kidding)
there’s been a misunderstanding, but nvm 😉
Btw, quoting a pilot that flew at least 2 of involved types, sensor fusion is much more advanced on Rafale than on E/F. NG would be a different beast with irst etc.
I was just meaning that the so called gap between 4th and 5th gen is much larger between legacy US planes and new planes than Euro planes and F22/F35
