India's First Stealth Fighter To Fly In 4 Months

xmpcray writes "Less than four months from now, India's first stealth fighter will fly for the first time. It is called the Fifth Generation Fighter Aircraft, or FGFA, and is being developed in Russia by Sukhoi. Several of the technologies being developed for the stealth fighter have evolved from those used in the Sukhoi 30 MKI. Considered the most maneuverable fighter in the world, the Sukhoi 30 MKI uses thrust vectored engines, which deflect the exhaust from its engines to extreme angles, enabling the jet to pull off violent maneuvers like a flat spin — where the jet literally spins around on its axis."

Interesting stuff

The end of last year, a couple videos came out with an American F-15 pilot talking about what it was like going up against the Indian Air Force Su-30MKI. It was quite interesting, as the vectored thrust did offer additional maneuverability but it came at a cost. That isn't to say that this new jet and training wont overcome that advantage, but it was a glimpse into the world of air to air combat I don't think makes it out into the civilian world all that often. The clips were put up on youtube - I'll link to both.

Basically if I understand it correctly the vectored thrust allowed them to turn, but they would lose airspeed and altitude in the process. As the fighter types say - speed is life - and once it happened they were apparently easy pickings. This FlightGlobal writeup about it may do a better job of explaining.

But I wonder is how much longer this will matter. The Lockheed video on their DAS for the F-35 pretty much asserts that the system makes maneuverability irrelevant. I realize that it's a vendor sales presentation, but at the same time I know off-bore-sight missiles are pretty much a done deal. Stealthiness helps some, but I doubt it would be enough as these systems keep improving. It seems soon the primary factor in air to air combat will be the quality of radar and missiles that are available.
 
When I bring this up with current military folks, they say they think rules of engagement will keep it from going that far. I can see that in situations where one side has complete air superiority - but if it comes to evenly matched sides, I think ROE will be out the window when sticking to it means losing. The whole thing is rather disconcerting as we seem to be developing better ways to kill just as quickly as all our other tech is advancing but I don't see leaps in our ability to live peacefully or get along keeping up with it all.

Stealthy?

Am I the only one that looked at the thing and thought "it doesn't look very stealthy." No, I'm not talking about the paint. Just the fact that the intakes and some other features look like they are going to be big scatterers and contribute significantly to RCS. My understanding is that vectored thrust also has a significant thermal and radar signature... This sort of seems like Russia trying maintain prestige and credibility against F-22 with someone else conveniently picking up a big chunk of the tab. Then again, India is probably buying them to neutralize Pakastani F-16's, so it may be worth the investment in their minds. I'd have a hard time believing that these would give even F-15E's or Super Hornets a tough time.

I'm not so sure about the Australian Over THe Horizon radar being unable to be used by SAM's for targeting.

My uncle used to be SAM commander (or whatever it's called) and he said there were plenty of times when they would lock on and fire at aircraft way over the horizon, when engaging in war games with the US. This was despite AWACS and similar.

Though he did say that most of these were with active radar, however when they (the US) started running stealth fighters in the games, they weren't able to track them. However, almost straight away all of the SAM sites were quickly sent down to the DSTO for upgrades, and each one came back with a special little switch which they would flick when ever certain conditions were met. He surmised that this allowed them to track and lock on aircraft using stealth technology using the OTH system.

They get taught about every single switch, how it works and what it does, so that they can fully understand the system, and ensure that it operates no matter what, or can recognize when somethings wrong. However, when this new switch was installed, it was kept quiet, they weren't told anything but "When this happens. Flick this.", and so they did, and from then on it was able to track and lock on any of these stealth fighters.

I could have my information wrong, but it sounds valid to me. I'd be interested to hear if anyone knows any details or has any other information on this system.
