Lockheed Martin F-35 Lightning and F-22 'Raptor' : News & Discussion

IRST is relatively short range and the range information it provides can be dubious, by then the Rafale will already be shot down. And you think OSF can outrange that huge pod F-18Es can carry?

The amraam's can far easily be dodged. And the OSF has public range of 75-100km. So Rafale can very well go without being detected provided spectra is as good as claimed. Most of teen fighters won't be carrying the podded irst that's the argument. The AAS-42 irst has a range of 185km so most probably the irst pods would have 200+ km range. Noone has procured the irst pods. It's just a marketing gimmick for now. There's a reason the super-hornet has been an export failure.
 
The EUM agreement is for the protection of American IP, it has nothing to do with how a weapon system can be used.
End-user monitoring is part of the end-user agreement. The agreement most certainly spells out how and what limitations, a weapon system can be used.

Why do you think the UAE is having a dummy spit?

That's UAE/F-35 specific. It's for the UAE to deal with.

With India, it's simple. Follow our rules or don't bother participating. It's pretty much why the Americans withdrew from the AESA radar tender for the LCA Mk1A.

When it comes to protecting American IP, we accept that. But we don't accept restrictions on who we can use American weapons. AFAIK, the only thing we have that's American and has such a constraint is the USS Trenton that was transferred to the IN. We can't use it to invade other countries, which is fine, 'cause we use it for training. In any case, it doesn't matter since our standards for going to war are higher than in America.

There's detection range and targeting range, two different things. In all tests of 'SPECTRA' the Rafale has always used an active system for ranging. The radar won't work against APG-79(V)4/5 EA at 100km and a laser is limited to about 20km, at which point you don't really need it.

Wrong. The IRST probes have been procured.

AMRAAMs aren't that easy to dodge.
 
That looks the same size as the OLS or any IRST located on the nose.



That's not how it works. Rather it depends on how the array is choreographed. A fighter array performs just one or two functions at a time, so a regular EW antenna is enough, whereas large radars can perform multiple functions at once, since its greater number of T/R modules can be divided many more times.

I mean, if your ground radar has a 3mx3m antenna, then you can divide it into 9 1mx1m antennas to create 9 main beams. So then your fighter radar has enough T/R resources to create 9 beams for EA whereas your dedicated EW suite can only generate a much smaller number of beams at a time.

Whether the Meteor becomes useless or not depends far more on the quality of the hardware and software rather than the size of the antenna. Stuff like this can only be discovered during evaluations, exercises or war. It's outside the realms of speculation.
100km vs 200km. Far more powerful optics.

It's a much larger radar than the Rafales with GaN modules and jamming power is proportional to 1/R^2, radar range is proportional to 1/R^4. The tiny GaAs Rafale radar had zero chance, even in a straight range for range test.

No one's gonna know the actual range of IRSTs. Anyway you want your IRST on the airframe, not on a drop tank.

600mm to 700mm is not too much of a difference. GaN changes the game though.

The real question is if the SH will be upgraded with GaN for new sales, like in Germany, India etc. Rafale will likely come with GaN on Spectra, but the SH should gain a significant advantage if it gets it on both.
 
185km vs 100km. The French one isn't even very good.
Well my eyes can see a satellite turning around the earth at more than 500 km or the sun at million kilometers from the earth. Does this mean that my eyes are better than EODAS or that you don't even understand what you're speaking of ?
 
And sorry but optics have no superpower. You can speak of fields of view, aperture, magnification ...
Magnification and processing.

We're obviously discussing seeing fighters.

If you're always carrying drop tanks, as the SH, Rafale and Typhoon always are, you can make a fair argument for putting on the tanks since it doesn't increase the overall RCS or Cd.

1368 vs 840 modules.

Point is GaN is in-service right now on APG-79V4, for Rafale it's years off, by then AIM-260 will be available. And for ground missions the Rafale does not have AARGM capability, nor any close equivalent.

There're nothing obvious if you don't use the same reference. To be clear speaking of range with passive systems is a joke, you have to speak of angular resolution and nothing else. You can also use total fiel of view if you want.
Even a 4*4 CCD can have a better FoV if the optics are made for or a better angular resolution if the optics are made for... To conclude If you don't know the resolution of the captor and if you don't know how the optics are made, comparing rafale DDM and EODAS is just a joke.

It's useful until the time it needs to be dropped. That's a huge no-no.

It's fine for the Growler, or if an SH is on an ISR mission. But during combat, it's not gonna be lugging it around inside enemy territory. That's a pretty ridiculous drawback.

Makes sense that one's exaggerated and the other is underestated.

Being available today doesn't really apply to future users. First, it needs to become available on the SH. Then it needs to be as good as, if not better than, what the Typhoon and Rafale will get after 2025.

Dunno why you think the AIM-260 requires special mention. By the time Typhoon and Rafale get a GaN upgrade, the Meteor would get an upgrade as well.

And the ARM's not a problem, if Dassault fails to get one of their own, the DRDO's NGARM can be made available for Rafale customers.

Drop tanks are hardly ever discarded these days, and the central one doesn't affect performance much.

Nah, that's just the size of them, the Rafale's radar is probably the smallest of all the modern fighters.

If it's in-service it's available.

The only potential upgrade for the Meteor on the horizon is an AESA radar and that's a UK-Japanese project.

NGARM isn't available right now and it would surprise me if AARGM wasn't better , and AARGM-ER will be better still.

Captor is a Typhoon radar, nothing to do with IRST.

This conversation was also done on keypubs. EODAS has 6 apertures, all with higher resolution than either of the DDM-NG sensors. But we were discussing SH and Rafale IRST.

:rolleyes:

'Cause no one's fighting peer or near-peer adversaries, only desert donkeys with no air force, so no one chasing them around.

Even though it is the smallest, it still has excellent range performance. System design matters a lot. Particularly the antenna and the cooling system.

Not necessarily.

Even that can be an option.

NGARM isn't available right now

Merely next year.

and it would surprise me if AARGM wasn't better , and AARGM-ER will be better still.

Subjective.
