Wondering how ASQ-139 capes are exclusive? Genuinely interested.

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.

It does not have 360 as the plane body block the view from below and somewhat to the front and sides.

Being only two sensors on the tail means that the plane creates a large blind spot to the front and beneath the fighter.

[I]* The F35 will have its DAS operational in 2018, Gripen E will have PAWS-2 at the same time (EF2000 will likely have that, Pak FA will just a few years later also have a similar sensor suite and possibly Rafale as well).

PAWS-2: It is nowhere near DAS functionality. It only does missile launch and approach functions. No nav, no video, no ground fire, no arty, no BDA, no sync to SAR, no missile guidance, no wingman or other airborne tracking, etc .

btw, PAWS-2 is already on Israili F-16I fighters.

Rafale is working on a system that only has 2 cameras on the tail which means HUGE blind-spots beneath the airframe and will likely have less visual acuity.

Nothing has been told of EF2000 development in this area as they are still stuck with an active radar based MAWS.

Nothing in known about the new systems on the PakFa other than their locations.

First, the scan rates of an IRST vs a radar, especially an AESA or PESA are not at all comparable.

Second, saying that most shots come from 10-2 is pure supposition on your part.

I was speaking of the F-22’s use of radar without EVER letting the target know it’s coming. So many of the post-action interviews talk about the target not knowing the F-22’s is even in the area until it zooms past or the controller radios to say you are dead.

On the IRST issue, it does not work that way. IRST would have to be looking directly towards the launch aircraft at the moment of launch in order to see it. Maybe you are thinking about an IR MAWS, which most aircraft do not have and will become less relevant as newer and longer ranged missiles come online.

IIRC the larger exercise areas like Red Flag and Norther Edge do simulate the RWR and MAWS functionality of their respective aggressor planes.

Sorry sorry? Umm, try to google 101KS-O, or do you really believe that “oh it’s a backward facing IRST” nonsense

So you are guessing that it is a DIRCM?
