The article says ‘such as the AMRAAM’. A larger missile would be a lot bigger so it would be even less likely it would carry 100 missiles, maybe 20 or something.
Perhaps it could be used to defend an base against cruise missiles, that’s about it. And I doubt they could mount 100 missiles per B-52.
That’s the worst idea since communism. Not only are they going to lose the B-52, but they’re going to lose 100 good missiles with it.
Because it is cheaper. An IRST costs about 1/3 of a radar and a pod can be switched quickly from an aircraft to another. So they could get like 50-100 pods for 300 planes. Perhaps it could launch AMRAAMs with data from the IRST and off board data.
Of course a radar would be better, depends on how much you’re willing to spend.
Perhaps an homeland security fighter with AiM9X II (ER) for the ones that are truely supersonic.
Thanks for the link b/w.
With a podded IRST maybe.
Another urban myth floating around is the claim that the IRST housing compromises stealth
“The IRST housing is turned backwards when not in use, and its rear is treated with radar-absorbent material (RAM) to reduce its radar return. “
If they are trying to hide the IRST seeker, that means that the frontal RCS of the plane is probably of the same order of magnitude or less than a standard IRST seeker. Otherwise why bother doing that? So what it the RCS of IRST seekers usually? Probably still quite low. That could mean that the PAK-FA RCS from the front is lower than some would assume.
The chart literally only mentioned skin temperature
But the increase in skin temperature is not that much. It is increasing slowly in fact, the increase seems to be independent of the transsonic regime per se.
So what causes that sudden increase in detection range around mach 1? Is it the compression of air molecules in the shock wave that produces heat or what?
F-35 wont face stealth aircraft all the time either
Non stealth aircraft have IRSTs so they can detect the stealth planes if the detection range increases that much.
They extended the acceleration time because they had no choice.
An aircraft at mach 1.0 is detected twice as far away as an aircraft at mach 0.8, Mach 1.4 is 2.7 times, Mach 2.0 is 3.4.
If you are going to go supersonic, you shouldn’t be low supersonic. 1.8 is actually pretty decent, still not worth the increased detection range, design compromises and fuel burn though, imo; the F-22 is short legged enough as it is.
What causes this peak in transsonic? Wouldn’t that involve the use of AB in transsonic by chance?
The F-35 would also probably go supersonic to launch. The ability to be capable of mach 1.6 and the focus on transsonic acceleration is not there for nothing.
Artists impression don’t necessarily become reality as history has shown.
If you truly want speed to improve capability, then you need to aim above M5.0, not above M2.0.
I disagree, going superfast will indeed result in a very high IR signature, flying at about mach 1.4 would not, while providing a good speed above the TS regime and the ability to give more energy to the missiles.
The problem is not to have a performance disadvantage that is too high against the opponent. 20-25% less speed might be acceptable if the F-35 is more stealthy, but more than that, the disadvantage would be too great. For a multirole plane the tradeoff would be acceptable, for a pure fighter it would not.
And the F-117 has existed since 1983, so the argument does hold valid.
Well it isn’t an interceptor, that much is true, but trends in air combat studies have shown that higher speed increases detectability. There’s little point in taking measures to improve IR stealth and then flying at such a speed that it makes them almost irrelevant.
I don’t see the point you’re trying to make with the F-117, the F-117 is not a fighter.
Why did the USAF want more than the 187 F-22 if that kind of performances is not needed? Clearly the ability to supercruise is an advantage for a pure fighter.
Also how does the friction increase the IR signature? I would argue that if the plane flies faster, it can fight higher where there is less friction, so that would partially reduce the problem. Also the enemy sensor will have a detection range proportional to the square root of IR signature.
I am not sure the level of speed of the F-22 would be needed ( around mach 1.75 supercruise), but enough supercruise capability to stay above the transsonic regime would be an advantage. Drag decreases at mach 1.1-1.25 or so, so if say the F-35 had 10% less drag, that could be enough to go beyond that transsonic range and get substantial supercruise capability.
Thanks for the link, good read.
The paragraph on lead laser is interesting I had never heard about that. So the pilot would have to try to do it manually to have a good pk, what a PITA.
The drawings look static to me.
Even when the drawing looks kinda similar to the YF-23? i.e. the LM drawing.
To cover ground for intercepts quicker. At the time stealth vs stealth wasn’t such a consideration because no enemy had anything similar on the horizon.
The Flanker and the Fulcrum have had IRSTs since the mid 80’s, so that argument doesn’t hold.
The JSF was designed for subsonic range and no more than F-16/F-18 speed because it was meant to be multirole, not because supercruise was considered useless or almost useless.
Mmh not too convinced… Check the drawings for the 6th gens, they look damn fast. I think you simplify things too much. In some cases fighters have to go supersonic. That’s when the SHTFs for your IR sig and fuel reserves. But it some cases using slow tactics could work ( that’s what I said btw in the rafale thread ) .
