The combination of indignation, whining, and general butthurt exhibited by many of our British posters here is rather unbecoming, but certainly amusing.

There are plenty of other forums for talking about bottoms if you’re that way inclined. Why would one be ‘butt hurt’ over a victory?

Great, tie up the entire GB armed forces in defense of FI,
but you won’t be wasting space for me no more

What would you suggest? Bending over and complaining about the symptoms alluded to by Rii above?

Integrated versus federated systems were a BFD in the 1990s. My old scanner and printer that were run from dedicated cards in my CPU were integrated because you could not put a computer and memory in the peripherals. My phone, camera, laptop, iPad, desktop and all-in-one are federated. As long as my WiFi is working…

Megapixel? The then-supplier (Cincinnati Electronics, now L-3) blabbed that years ago. The problem is the element size, that was constant for a long time – this is not a visual-light device. There are smaller elements (more pixels for same size) in the labs.

So no source, thought so. When I type “F-35 DAS megapixel” into google all it gives me is one page containing the word ‘megapixel’ and it’s an advert for a camera on the same page as the main article.

A megapixel staring IR that covers one-sixth of a sphere – you’ll find the resolution in there if you do the math. An IR telescope with a scanning mirror is a different kettle of fish.

As for seeker range: The radar range equation is not your friend because seekers are not intended as long-range devices. Received energy at the transmitter varies with the fourth power of range, and stealth gets very, very difficult to do as the range closes in. And don’t be surprised to see more dual-mode seekers coming along with more compact IR systems and GaN AESAs.

Source for “megapixel”?

I doubt it. The resolution is not there and I doubt that kind of accuracy is there either. Also you have to remember that what you get at long distance if you do not narrow your FOV is a cluster of dots.

So now you have access to DAS resolution specifications? Radar bearing accuracy is typically ~1 microradian and IRST is at least an order of magnitude better.

(Reuters) – Lockheed Martin Corp (LMT.N) and U.S. defense officials have reached agreement on the terms of a contract worth about $4 billion for an eighth batch of 43 F-35 fighter jets, sources familiar with the deal said on Thursday.

The UK would be better off allowing their kit or someone they can influence’s kit in the Saab. Even limited control is some control which is better than no control. The nightmare scenario would be facing Gripen NG sweep over The Falklands that carried both ELTA radar and ECM/eccm gear as well as Python V/U Darter that has a working datalink. That would be bad.

Not really and what are Argentinians going to buy these Gripens with? Sand?

Except that the earliest we are looking at is ten years from now and then maybe. Soooo these Gripen NG will be facing hordes of FCAS and T3bplus Typhoon:D

It would certainly be facing GaN Captor-E equipped Typhoons and 80+ F-35Bs, all with Meteor and CAMM(A) by then, not to mention SPEAR, Storm Shadow + MLU and maybe even Perseus. And last time they couldn’t even get a single kill on a Harrier with Mirages. Then there’s a matter that they won’t have anywhere to take off from because all their airbases will have been wiped out by TLAM-Es or MdCNs, from either of 7 Astute SSNs or 13 Type 26s, and all their ships sunk by Astute class SSNs with the latest upgrade of the Spearfish torpedo. They’re also unlikely to have much luck getting anything past several hundred Aster 30s, CAMM(M)s and Artisan and Smart-L Mk2 radars.

It would be a really, really bad 24 hours for them.

Plenty. And for the same reason that Argentina MIGHT pose a threat to FI

Domestic politics.

Providing decent living accommodation or PTSD counselling does not win votes but standing up to the ‘evil argies’ for not actually tax paying but still British citizens of FI does win votes

Exactly! There’d be no political dissent whatsoever and the MoD would have a blank cheque to open up an account on them with, backed by unwavering support from voters.

Does that mean a single F-35 can triangulate between DAS and EOTS?

How in the name of elementary school geometry do you think that might happen?

By making a triangle with 2 angles and a known separation. At least you know they’re separate systems now, so you are learning.

I think the F-35 can be taken by surprise but at somewhat longer range, maybe 15-30 km if the enemy is using an good IRST or AESA radar with LPI modes ( depending also on the angle ), but it will be warned of enemy planes approaching in WVR.

I can be wrong on that, data on the sensors ranges are classified but that sounds logical.

What might happen also is that the EOTS can continue to track enemy planes in BVR once the F-35 has crossed them. I don’t think the DAS is necessarily needed if the EOTS knows where the enemy plane is approximately ( but continuously tracking it after the planes have crossed ).

Seems EOTS has IRST capability too, so presumably it would be similar or better than conventional IRST.
