Many russian sources even old ones claims than KS-O is IRST capable. LMFS picture says exactly that.

I think, combination of UV and IR is used because UV sensors has wide angle lenses and IR is narrow zoom like lenses for better detection range. So UV are used as reliable way detect launches and initial vectors and IR is for tracking and DIRCM.

how many R-37’s will the MiG-35 be able to carry? :confused:

Looks like four is wouldn’t be a problem.

I did not know that India were looking at buying the Su-57 after cancelling the FGFA program, It’s weird.

You, at first, need to start something to be able cancel that later. FGFA have failed even to pass a preliminary design stage.

Here is some interesting actual information about Antonov, unfortunately in russian:

The whole story about the prices is simple. Russia do not buys the jets, Russia produces them. So for internal customers costs of acquiring are equal to costs of production with little if any profit to production companies. So foreign contracts are not relevant here.

well people still surprised when i told them that reliability is the only principal advantage of AESA compared to PESA.

Indeed, but, it seems, ROFAR will have a significant advantage in power efficiency over AESA and hybrid PESA.

R-77 with folded steering surfaces are 30×30 cm in size, so it looks possible to fit 6 missile per bay.

Thus make it what was described in Stimson back in 1998 Introduction to airborne radar book. But somehow people keep thinking of it being something otherworldly.

Exactly the same way people are thinking about an AESA.

MFI did start in 1986. After dissolution of USSR (even earlier, in fact) funds was cut. The program struggled since early 90’s. 1.42 prototype was built in 1994 but 1.44 flew only in 2000. Russia inherits MIF from USSR as many other programs like NK-93, but didn’t able to afford them. They were developed mostly by designer’s will, rather government’s interest.

It’s a wired logic, to claim a connections between two different programs from different decades, different design beurs and different countries. In fact, ATF has much more connections with ATF, than PAK-FA with MIF or C-37. C-37 is not even a program, just a technology demonstrator that Sukhoi built on their own will.

Similar programs or not it’s not an issue. Blaming SU-57 for small small orders or for not being ready in 2018 is an issue. Is such kind of a statements are valid?
