You don’t think that 16-and-a-half ‘S’ ducts will put the PAK-FA in the F-22 RCS ball-palk?……you’re right it must be that IRST with its B-52 signature.
Speaking of which, did they cannibalise the B-52 for the F-22’s tail-fins? :confused:overG, dooo sooomething!!!
I’m afraid I don’t think anything involving the intakes will make the difference needed to get into that ball park. We’ll have to wait and see what the production models look like, but the prototypes aren’t there yet with the fit and finish, planform alignment, the conventionally shaped IRST, the bulbous engines, etc…
Erm……the PAK-FA’s frontal RCS will at least have to equal the F-22 as a survivability pre-requisite.
…but the good news is T-50-03 will have 16 ‘S’-ducts per engine!!!!!:eek: (;)).
That doesn’t mean that it is though, and from the looks of it I suspect that it’s not(especially considering the Russians are even conceding that).
You are not being conservative though if you assume 41 minutes at the Raptor’s maximum supercruise Mach number of 1.7 to 1.8. It’s design point for supersonic cruise is around Mach 1.5, so that range is where it will achieve its best efficiency and endurance.
It may very well be M1.5, but that wasn’t specified. The thing to bear in mind though is that M1.5 was only ever given as a minimum specification. We now know that the F-22’s supercruise speed is higher than that. Now if we’re going to use the term cruise, in the normally understood meaning, then I don’t think you can automatically come to the conclusion that M1.5 is what they’re talking about.
That was a special event during a point to point flight in general. In that story no details were given except the names and time. So nothing about the climb-out and landing back profile and the related height of the transit.
It did say in the anti-cruise missile role, when mentioning that duration though. In any event, if it travels M1.5-1.8 for 41 minutes, that puts its range much higher than many here are willing to give credit for.
Yes there are Technical means like what you have mentioned and non technical ( information gathering as thats more effective ) that both sides have at their disposal.
Please note that the Chief Designer mentions that RCS is very close to F-22 and not identical or better , its an acknowledgment that PAK-FA RCS will not be as good as F-22 but very close to it , that is probably because what I think is Sukhoi approach on achieving super maneuverability something that they do not want to give up after Su-35 , so its a trade off based on each countries requirement.
The point many are making though in their critiques of the comparison, is that they were stating an RCS of .3-.5m^2 for the PAK FA, and saying that’s comparable to the F-22. Either they’re being really really conservative with that estimate, or……….they’re simply full of it. I suspect the truth lies somewhere in the middle, with ample helpings of each.
The trend is towards low frequency OTH radars and proliferation of BAMS-style UAVs in the next 20 years. Remember, the systems you purchase today have to deal with tomorrow’s threats too.
I’m just not so sure what sort of resolution those radars would have against sea clutter, and widely spaced ships though. At $30-55 million per unit, I’m not sure how many nations could afford a large fleet of these though.
IMO, the USN needs an unrefueled combat radius of 1600+ km. Any adversary who can deploy a sophisticated IADS can also has an ability to locate a CVBG within 600-800 km of its coastline. This means the CVBG must operate from farther away to stay “lost in the big blue sea”. If it fails to do so, it becomes an anti-shipping missile magnet and cannot perform its primary role of projecting power inland. The amount of internal fuel required to fly 1600 km forces the airplane across the “light attack” threshold and solidly into the arena of “medium attack”. F-35 was forever constrained to be “light attack” by the requirement to fit on the elevator of an LHD.
I’m not so sure that having a good IADS means that a country can easily locate a CVBG at 600-800km off shore. Unless they have a pretty sizeable Maritime surveillance capability, there’s no way they can search that volume of ocean.
I thought the F-35C will have a pretty decent range…?
What combat radius would the Navy really want then?
~768nm radius on internal, and ~927nm w/ 2 EFTs.
Ideally, they’d probably like a striker with a radius ~1000nm or greater on internal fuel.
Well I have already for some time been convinced that the F-35 will be fantastic fighter, I think it will be able to wipe the floor with any 4.5 gen fighter out there. And more importantly it will be much more difficult to hit from the ground as well.
The questions that remains are:
1. Will it be able to deliver on technical capabilities? I think the answer will be yes.
2. Will it be “affordable” and with acceptable delays? I think this is where the main uncertainty is at the moment.
And pfcem has not yet conviced me w.r.t. item 2 above… 🙂
Well it won’t be as cheap as hoped for, but if folks don’t start backing out of the program, there’s hope to keep the price from an endless upward spiral.
My question is: what can the evil russkies learn about the RCS of F-22 when F-22 are on a patrol up in alaska ?
Well, with RCS enhancers, and external fuel tanks, probably not a whole lot.

Critics: Time to bail on Navy JSF

😀
How many of those “observers/critics” are in the Navy or Naval aviation?
NONE of those parameters have been made public for the F-35A so you have no clue what you are talking about.
What we DO have is public statments from pilots who have flown the F-35A & the USAF/DOD/F-35 Program Office. From that it is known the acceleration & turning performance of a COMBAT LOADED F-35A “almost exactly match a clean Block 50 F-16”.
A F-16 will stall at a lower AoA than a F-35A.
BS. The F-35A was designed to replace the F-16, not the F-105.
I challenge you to find ANYONE who has flown (or flown against) the F/A-18 who would dare desribe it as a “sh*tbox of an airframe”.
***
Nice try. But 240-3 is a PRE WEIGHT REDUCTION standard AND those numbers are for a COMBAT LOADED F-35A – thats ~23,000 lbs of weapons & fuel. And just were do you get that a F-16 can accelerate from Mach 0.8 to Mach 1.2 @ 30,000′ in 30 secs?
Comments from those who have actually flown the F-35 state that it OUT ACCELERATES the F-16.
***
No we do not have to wait that long. PLENT of pilots will have flow the F-35 & commented on how WELL it flys before then, in fact some ALREADY HAVE.
No it is a muti-role FIGHTER. Just like the F-16, the F/A-18, the Mirage 2000, The Rafale, the Eurorighter Typhoon, the Fuclrum, the Flanker… It IS in fact intended (& will be) THE primary air-to-air platform for MANY services around the world.
The F-35A OEW is 26,664 lbs. That is ‘just” ~2400 lbs heavier than the Eurofighter Typhoon. Remarkable consider all that is ‘crammed’ INSIDE an airframe similar size.
The F135 won’t fit in an F-16. In fact the F135 has almost as much DRY thrust as a F100-PW-229 &/or F110-GE-110 in FULL AFTERBURNER!
***
I suggest you join the 21st century. The F-22 was designed to do things differently.
That is a typical PEACETIME mission.
Wrong. THe F-22s out of Alaska carry drops tanks to hide their true radar signature. The combat radius/range of a F-22 with ‘just’ internal fuel is comparable to that of a F-15C with two drop tanks. The combat radius/range of a F-35 with ‘just’ internal fuel is GREATER than that of a F-16 with two drop tanks.
***
F-22’s don’t supercruise at full military power, they do it at 80% military power. Yes that is still a lot of fuel being burned every minute but A LOT less than any prefious fighter flying at the same speed/altitude.
F-22 supercruise VERY OFTEN & for significant periods of time.
***
No it is not.
Here’s a chart showing how F-35s compare with F-16s and F-18s in terms of instantaneous and sustained Gs, as well as acceleration. You’ll notice that the F-35(all 3 variants), exceed the F-16 and F-18 in all 3 categories.

Understand the difference between radius and range?
If you fly away from your base… your going to have to fly back again, unless you fancy landing your $200 million dollar aeroplane on a desert somewhere…
At a fuel fraction of only 0.24… I’d be quite surprised if the F-22 could supercruise for 30 mins.
Here, you believe LM press releases are gospel:
I was being conservative. There’ve been a number of stories on this including in Aviation Week, where the figure 41 minutes of supercruise was given.
I doubt DAS will have that all around coverage in all conditions. For one thing, it certainly cannot see behind objects, such as in mountainous terrain. Furthermore, LM’s wishful thinking describes situations like F-35 vs legacy 4th gen fighters, not vs other fifth gen fighters such as… another group of F-35s, let alone PAK-FAs. The element of surprise will always be there, F-35 is not going to change that.
How is this plane flying below and around mountains tracking the F-35, to sneak up exactly? It doesn’t matter if it’s a 4th or 5th Gen aircraft, as the DAS is IR, not radar, and forms a 360 degree bubble around, above, and below the F-35. Any heat source getting within 10-20nm(and that figure may be higher) is going to be detected(granted there may be unusual climactic conditions degrading the performance, but you still need to explain satisfactorily how the plane found the F-35).
No, the context was A2A, that’s why he mentioned the 4 AIM-7s on F-15s and 6 AIM-120s on F-22s. Then he realised what a stupid thing he said and changed the subject. You may go back and see for yourself.
Exhibit A- Post #687
Six is more than enough. The F-15s got 4 AIM-7s and the F-22A got 6 AIM-120s for good reasons, when F-35A is back to 4 AIM-120s.
If the threat approaches from a direction not expected, or stays where he isn’t visible, then the F-35 will simply not have 6-8 seconds of early warning.
The DAS has a longer range than 6-8 seconds of notification, and 360 degree coverage.
Yes, he is. He explicitly stated “…there are good reasons the F-35 is armed with only 2 AAMs” and then you come stating “No, it can be armed with more”, spoiling his fantasies.
And in the context he was referring to was on a strike configured load out.
