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

Low bypass ratio engines have greater advantages in the supersonic stage.
1. The core engine thrust accounts for a higher proportion. The core engine (internal duct) airflow of the low bypass ratio engine is ejected at high speed after combustion, which is more suitable for the high exhaust speed requirements during supersonic flight.
2. The external duct of the low bypass ratio engine is smaller or even has no external duct (such as turbojet engine), so the engine diameter is smaller, which reduces the shock wave resistance during supersonic flight.
3. The core engine of the low bypass ratio engine has more extreme working conditions (high temperature and high pressure), and has higher thermal efficiency in the supersonic state.

Although I do not agree that the Rafale fighter is suitable for supersonic cruise, I think the M88 engine is not a factor. The more important thing is that the aerodynamic design of the aircraft is more inclined to subsonic speed.

Rafale is not designed as a peak ASF in terms of performance, it loses some perfomance for low altitude agility and penetration at 200 feet. Typhoon is much more of an ASF, but loses out to the Rafale at low altitudes.

But F-22, Typhoon, and Rafale can supercruise at higher altitudes, and the engines can sustain those speeds. The only difference is the F-22's engine is a more modern design with counterrotating turbines. And of course its airframe is more suitable for high altitude.

All three are multirole.

The problem is that
if we are facing a country like Somalia or Houthi that lacks a modern air force and only has some modern air defense missiles, then it is feasible to penetrate at ultra-low altitudes below 200 feet.
But facing countries like Pakistan or China that have a large number of early warning aircraft, is this tactic still useful? In this conflict, the Rafale was shot down at an altitude of less than 100 meters. This proves that this tactic is useless.

Terrain-following is an evergreen tactic. It has the greatest chances of success. It was proven to be very successful against Pakistan.

No Rafales were shot down.


No military assets were lost to enemy fire during the entire operation.
 
Then the Rafale didn't even shoot down a JF-17,😂
Don't you see how small the Rafale radar is? Its diameter is 580mm. My god, it's not even as big as the JF-17.
I already admitted that small-nose cone is Rafale's only limitation as an ASF, here:

1000017763.jpg
But that doesn't make it a bad air-to-air fighter. If you design your plane for too many complex missions in more or less similar package/design then there will be some compromises here and there.

But the fact that Rafale is a superlative ASF fighter, Carrier-Borne fighter along with a great strike-jet "all at once" speak volumes about its versatility.

you're almost there RandomRadio!!
I am thinking we are perhaps 3 to 4 pages away from Randomradio finally posting "well yes the Rafale doesn't supercruise like the F-22, but the Rafale is still an ASF because it relies on agility and other tactics and advantages to win"

(bonus points he will respond to this exact section promising us I will be wrong and he would never change his incorrect position)

Hint: I even gave you an out with the Chip Berke video! but instead you decided to talk about Block 4 rather than lock onto "hey he says you don't need super speed!! You can win with sensors and avionics!!" The Rafale may not supercruise but it can win with sensors and avionics!!

its not too late!!

But F-22, Typhoon, and Rafale can supercruise at higher altitudes,

What are the altitudes exactly? Hard numbers please.

and the engines can sustain those speeds.
how? what is the data? We have gobs of information on the F-22 and an airshow pamphlet for the Rafale. "sustaining" is not going to happen for the Rafale and the lack of evidence should make that abundently clear. We never get data or numbers, we get descriptions.

"High altitude"

really? how high exactly

"very high!"

"Sustain those speeds"

really for how long?

"goodly long!"

we literally hear more about the CAD software used to design the Rafale than we do this supposed Supercruise capability. everyone and their mother knows the F-22 supercruises its mentioned almost synonymously with the F-22. We never hear such things with Rafale. We have 2 ever-recycled examples one of which is coming on 20 years old, and looks suspiciously like a test flight.

lets compare mentions of Supercruise in some of the obvious places:

USAF F-22 Datasheet mentions: 6
P&W F119 datasheet: 1

Mentions by Dassault on their website: 0
Mentions in 1987 development paper of Rafale by Program Manager: 0
Mentions by Snecma on M88: 0
A search on the official website of France Air and Space force: 0
French Navy Website: 0

supercruise is such a game changing feature they don't bother to mention it at all. Theyre still publishing papers on the F-22's supercruise over 25 years after the First F-22 did it over Edwards in 1999.
The only difference is the F-22's engine is a more modern design with counterrotating turbines.

HAHAHAHA

How so?!

You guys have been discussing this for quite some time, but no one has looked up the data on the bypass ratio of M88?
Of course we are not going to look up data on the Rafale, it would harpoon his entire world view.


Something I have previously said. The Rafale doesn't even match the FA-18, let alone the F-35.
For as smart as Randomradio thinks he is he fell for a very obvious trap. not his fault in a way Dassault fell for it, and Randomradio believes everything France says so no surprise

what we keep hearing is that Rafale has made a tremendous splash, but not only did we not see the Splash, we don't even see the ripples. We see no impact and no evidence of impact.
When the F-22 showed up it completely changed the way the USAF conducted air warfare. The F-15 which had ruled the roost for decades was suddenly 2nd place. That is pretty jarring. from predator to prey nearly overnight. The stories that began to be reported and passed on anecdotally from RedFlags in both Alaska and Nevada where nothing short of spellbinding. When the F-22 uses supercruise to humilate friends and foe alike, we hear about it. When the Rafale "uses supercruise" we get to see it as a wikipedia footnote and no one who operates the Rafale mentions it at all.
it makes no sense. its like saying you found a dollar on the ground and also invented time travel.

If the Rafale could supercruise in a meaningful way, you would have heard about it as a meaningful thing.

Where is the impact of the supercruising "almost an F-22!!" ASF Rafale? What impact did it have on the SU-30MKI or the rest of the Indian Air force? Has anyone seen any reports on that? The Rafale is a dud in that sense. its a good multirole fighter but its not an F-22, its not even a Flanker MKI and if it was suddenly better than the MKI to say that would be a "Shake up" of the IAF would be an understatement.
what we get instead are blathering fanboys trying to take the most scant evidence from the most far flung sources and conjecture that is extremely light on any kind of detail. We have had the details of the ATF programs "Mission 1" for decades. its completely explicit and heavy on actual numbers to include the entire expected mission profile.

The Rafale is so amazing, so impactful with its supercruise, its not being mentioned at all by any of its users, there are no tactics or doctrines that incorporate its use. We hear nothing of Flankers or Mirage 2000s having to completely reimagine how to survive and fight against it. We hear far more conversations about the F-35 in that sense and how it changes the old ways overnight, but lets not talk about that for the moment.

Here is where Dassault and others completely messed up. (Take note Randomradio-- this is your ticket out of your untenable position!) When The F-22 was supercruising and making it famous, Dassault rather than fall for the "trick" that was "you either have it or your dead!" promoted by the USAF, LM, et al was simply to say:

"so what? we don't need supercruise to win in the air."


that is all they needed to say. instead they fell for the trick. Random fell for it too. He dutifully told us you need Supercruise. that is the defining charecteritic. But oops!! Rafale doesn't supercruise like an F-22. It supercruises like everything else including examples he gave us going back to the 1950s.

an F-15 can "Supercruise" in the style of Rafale. in fact Randomradio lists all kinds of aircraft that can do this gimmick of F-22 Supercruise. Guess why the USAF never mentioned SC for the F-15? because they know its basically useless. do they mention supercruise for the F-22?
Yes. every time.
I still have yet to see how as Randomradio plays this "yes everything can supercruise as a novelty even an attack aircraft!" but the Rafale's gimmick is not a gimmick!

I see no difference, I see no evidence, I see nothing other than Random claiming so, that Rafale gimmick fake SC is any different than everyone else Fake Gimmick SC. he just says its different! The Rafale SC is like the F-22!

How? never explained
what are the differences using data? Files never found.

Dassault fell right into the trap of trying to measure up to something they can't possibly measure up to. The only way to make a Rafale compete with the F-22 on its level is to make a completely different aircraft, and this goes for the engine too. How do you make Snecma M88 capable of SC? use a different engine.
please note, that never ever in the history of ever did Boeing every try to convince anyone that the Super Hornet was a supercruiser. that was fools gambit and they promoted their aircraft without it. Something the Eurocanards failed to understand.

Rafale was never designed to fight and win in the air like an F-22, but they fell for the trick that in order to do so, they had to play by the rules of the USAF and F-22 consortium. if gifted to the USAF the Rafale would be classified as basically a sophisticated F-16. Multirole fighter, good avionics, not an ASF, no supercruise, no Stealth at the level of acceptability. "special, just like everyone else"

Why hasn't anyone asked "why?" why would the French AF and Navy demand supercruise for the Rafale? when did the French armed forces of Dassault come to the conclusion that the MCX Program that became Rafale had to have a capability no one asked for?
Where are the studies that were used? where was the research? What specific aspects of the Rafale design and development were used to create sustainable supercruise for something like Mission 1 of the ATF? What is the supercruise profile of the MCX/Rafale? where?

searching the 1987 document we get not just explanations for the design studies, but we have the Program manager "showing his work" and giving us the studies and indicative's that LEAD to those design decisions. thats really helpful stuff. "here is how we built the Rafale, here is the study that lead us to this design feature" There is no such thing mentioned at all any where in France about supercruise at all. or sustained supersonic flight. no requirements, nothing. zero evidence in any phase.
zero acknowledge from the designers or users, no operational impacts. we see no impact, no ripples, no consequences.


Randomradio keeps trying to convince us that a 747 and a concorde are the same thing because they both have 4 engines, carry passengers, and fly high. All those things are true, and the 747 is an impressive feat of engineering, but come on now; not a concorde. really obvious for anyone who is not completely and willfully blinded:

The only difference is the F-22's engine is a more modern design with counterrotating turbines.

the F-22 supercruises because it actually supercruises, and the Rafale "supercruises" because an airshow pamphlets says it does.

Supercruise is more effective in a 5th gen because it carries all its weapons internally. Supercruise with weapons and EFTs might be detrimental for fuel-efficiency. So it's indeed more of a 5th gen thing than 4th or 4+ gen thing.

Anyways, the point remains that Rafale is a very good dogfighter and a good ASF. Who cares whether it can supercruise like Raptor or not!

you have hit the proverbial nail on the head and this is where the Rafale is "stuck" for Randomradio. He declared point blank that in order to be an ASF supercruise is a requirement HAHA I'm sorry he actually said (twice) anything less is suicide, but the Rafale doesn't supercruise.

There are 2 Rafales now:
1. the actual Rafale as it exists in the real world.
2. The fictional Rafale that Randomradio desires.

number 1 option was not enough apparently, so we had to invent Number 2. Not a ringing endorsement for the Rafale!

I have no idea why so many people decided the Rafale had to be a poor imitation of the F-22 instead of a perfectly fine version of the Rafale.

When did "omnirole" become a regrettable hindrance?

remember a smart person would say "Rafale doesn't need to supercruise to do Air superiority, it can win without it" and simply dismiss supercruise as an unnecessary ingredient. watch a smart person do exactly that:

Who cares whether it can supercruise like Raptor or not!
Done! you did it mate! congratulations! its just that easy. what is that 9 words? 10? Dassault should mail you some money. please get in touch with the paid Dassault posters on this forum via PM.

but Randomradio made a silly declaration and can't find his way out. he is having to redefine entire words and working far far too hard to dig a hole deeper and deeper.
what has happened is that randomradio is terrified that if someone look at the Rafale objectively we will find a multirole fighter that relies on stealth and sensors along with solid kinematics to replace multiple aircraft for multiple air arms-- in other words an F-35. but of course the F-35 shares more DNA with the F-22, so its even harder to accept. The F-35 and the Rafale are very comparable. The F-35 just has to be big poopie and the Rafale is so amazing it is actually metaphysical. Sure there is no evidence of operationally useful supercruise, but who needs any when you "just know"

a very sad position as we are explained that the F-35 can't fly high, even though it has the exact same ceiling as the Rafale. 50,000 feet is listed for both. But we must remember that when the F-35 flies at 50,000ft that is not good enough. But when the Rafale does the same thing, it is good enough because 50,000 ft is close to the F-22, and of course the F-22 ceiling is 70,000 feet, but that RAfale falling short by nearly 4 miles is "close enough" (unless you are an F-35)
IF you want to see bias, please note that Randomradio has spent more time explaining F-35 Block 4 in massive sections and paragraphs and multiple links and explanations than he has about Rafales supercruise.

Imagine if Random looked into Rafale Supercruise with the same tenacity and respect for "the pentagon says" nature of the F-35's block 4. All the world wonders

Make no mistake Randomradio will come around, he simply has no other option. its really hard to find evidence of things that have not happened. That is why he is not providing any of the source material I have asked for. once he figures out he is trapped he will have no choice but to change his opinion. no worries! it will not dent his ego one bit and he will forget the whole thing happened, and tell us how Supercruise is a frivolous waste!

All aircraft are "Trade offs" in order to get to where the F-22 is they had to compromise in some areas, and one of the larger areas was simply cost. In order to do all these amazing things the F-22 cost a lot of money to develop, build, buy and now maintain. its very expensive aircraft and there are fewer than 200 of them in the world.

Rafale does a lot of jobs and for relatively low cost, Dassault and the French understand that is an extremely difficult undertaking and are far more proud of that then the idea that the Rafale was ASF that they threw some bomb capability onto. in the 1987 paper I read they explain how the Rafale intakes were picked to facilite the loading of weapons aft of the front undercarriage. None of this was done "on accident" and without forethought. there are a full 4 reasons the intakes on the Rafale "Are the way they are", and that is just one of them. There is a reason the Rafale has one fin as opposed to two, etc.

it is not "it supercruises because that is what ASF do, and the Rafale is an ASF aircraft so it probably was designed that way" you don't "luck" into F-22 level supercruise the entire machine from nose to tail and especially the engines had to be designed to facilitate Mach 1.5+ for long durations and it took many years of development and engineering and testing to pull it off.

its ignorance to think that these aircraft are not all impressive triumphs in their own unique ways, yes even the F-35.
 
I already admitted that small-nose cone is Rafale's only limitation as an ASF, here:

Relative to a much larger radar using the same TRMs, yes. But the Rafale's TRMs are more advanced.

At 580 mm, the area of the radar is 2642 cm2, and it has an est 1050 TRMs. So each TRM uses up 2.5 cm2 of space.
The F-35 at 800 mm, the area of the radar is 5027 cm2, and it has 1670 TRMs. So each TRM uses up 3 cm2.

Since the RBE2 AESA is more densely packed, the radar has better sidelobe suppression capabilities due to superior tapering precision. It means better ECCM.

The lower spacing also gives it a much wider scanning angle, at least 25% more. Meaning the RBE2 can see 25% more of the airspace than the F-35's radar.

Then, given the Rafale's TRM is already more advanced given its smaller size, it should have better antenna characteristics too. So if the antenna uses slightly higher peak power, has a higher bandwidth, and uses pulse compression, we can match or get more range and range resolution, while already possessing better steering and ECCM.

And with the F-35 struggling with cooling issues, even with a smaller radar, the Rafale's radar will outperform it.

So don't get fooled by such silly one-dimensional statements. The real metric is not the size of the aperture but the quality of the TRMs and cooling capabilities. With denser TRM packing, quality cooling, and excellent TRM characteristics, even though it has a smaller size, the radar can perform to the same level as radars twice its size.

Once GaN-on-diamond is implemented, if the element area is just 1.5 cm2, then the same radar will have 1760 TRMs, matching the F-35. If the XG comes with 1760 TRMs, with pulse compression it will even surpass the abilities of Virupaksha.

The only real disadvantage of a small radar is lower angular resolution due to its higher beamwidth. But that's managed by using multiple radars, advanced beamforming techniques using DoA, and running super-resolution algorithms. So Rafale's radar will be more than competitive with most other large aperture radars in the market.

:ROFLMAO:

The discussion was about whether Rafale is an ASF or not,

you successfully proved to us that Rafale is not an ASF, so thank you for that.

but it changed into Oh, the Rafale is not as good of a supercruiser as the F-22.

:ROFLMAO:
I wonder who decided to make Supercruise the key factor between success and a suicide?
oh wait I remember:
I'll repeat the statement as my previous post here again.

"No high altitude, no supercruise, no AS missions for you. If anyone assigns you one, then you're on a suicide mission."
but also:
don't get fooled by such silly one-dimensional statements.


:ROFLMAO:

and who continues to try and convince us the Rafale can supercruise in such a way?

But F-22, Typhoon, and Rafale can supercruise at higher altitudes, and the engines can sustain those speeds. The only difference is the F-22's engine is a more modern design with counterrotating turbines. And of course its airframe is more suitable for high altitude.

:ROFLMAO:

Rafale is not an ASF, source:

Low bypass ratio engines have greater advantages in the supersonic stage.
1. The core engine thrust accounts for a higher proportion. The core engine (internal duct) airflow of the low bypass ratio engine is ejected at high speed after combustion, which is more suitable for the high exhaust speed requirements during supersonic flight.
2. The external duct of the low bypass ratio engine is smaller or even has no external duct (such as turbojet engine), so the engine diameter is smaller, which reduces the shock wave resistance during supersonic flight.
3. The core engine of the low bypass ratio engine has more extreme working conditions (high temperature and high pressure), and has higher thermal efficiency in the supersonic state.

Although I do not agree that the Rafale fighter is suitable for supersonic cruise, I think the M88 engine is not a factor. The more important thing is that the aerodynamic design of the aircraft is more inclined to subsonic speed.

The engines are a very large factor. Heat is serious not just the exhaust or the engine core

The Gripen NG supercruise test was a pure PR mission. It was meant to generate headlines and trick fanboys. I have no idea why Randomradio is using the propotype, (no black boxes, no radio, etc) Rafale demonstrator for "supercruise proof" especailly when only 1 of these engines according to his link was even an M88!! What does this prove? a non production example of the Rafale, with a non standard engine is proof that the current Rafale can supercruise?

The rafale Supercruise that we hear about (that one time remember...) seems to indicate a test profile. They have achieved 9.9G on the F-35A in test. Does that mean F-35 pilots fling it all over the sky at 9.9 g on the reg? of course not but we have Rafale fans who genuiuely think the Rafale does this thing, and does it so commonly that we are continuing to use the same single source for decades. Its the kind of everyday thing that happens once in test 25 years ago!

in 1963 the US Navy landed a C-130 on the USS Forestal as a feasability study. Does the USN operate C-130s? yes. Can a C-130 Land on an aircraft carrier? yes. Does that mean C-130s operate from Carriers? Absolutely not. But if we use the Rafale supercruise standard there are C-130s operating from carriers, because they did that back in 1963.

Where there is smoke, there is fire the saying goes. but with the Rafale there is no smoke and can see where they might have been a small fire decades ago. F-22 was built as supercruiser, is employed as Supercruiser and that is because it supercruises in a useful sustainable fashion.

the F414 can probably deliver close to its pressure corrected Mil power thrust. an F-16 with no weapons or tanks and the PW229 engine can do the same kind of "supercruise" that a gripen NG can in the test in the same conditions.
but at Mach 1.5 at 40,000 feet and higher, your inlet temperature is up to around100 degree Farenhiet, and if you get up to Mach 1.7 , the inlet temperature is above 150 degrees F. It is at these high inlet temperature conditions that the Mil power thrust is dropping way off as the engine runs against its turbine temperature and rotor speed limits.

The Rafale can "supercruise" in a very limited manner before the limits get reached and the entire thing begins to overheat the pilot will then need to either back off and go back to the drudgery of subsonic which is what the Rafale was designed for of course, or he can just keep going and either degrade the engines lifespan or TBO. F119 was optimized knowing that temperatures are going to be a factor The F-22 intake is very cleverly designed even though it looks simple. Remember the F-22 and F119 were DESIGNED from the start to Supercruise so it had to be hardened and optimized for such temperatures and conditions

The Rafale and M88 are not optimized or designed for sustained supercruise. Taking a Rafale and trying to sustain Supercruise while basically redlining the engine to 100 percent, "but at least its not afterburner!!" while the temperatures climb is simply not a viable option in terms of not only sustainable flight in that moment, but in terms of maintaining squadron readiness after all the pilots burn out the engines attempting to do this other than a brief test flight.

This is why we don't have a revolution in French or Indian Air Force tactics. without a single doubt the Mirage 2000 could do the same tricks as the Rafale *but better* and we never had Mirage 2000 operators trying to convince they were sustaining supercruise in any meaningful way. worth wondering why

primary concern regarding speed was making sure the Ralafe could go SLOW so that it could land on a ship. The intake can go up to mach 2, but with an emphasis on keeping it simple and good airflow at high AOA.

one of the reasons I know the Rafale is not being used for sustained supercruise is that half the Rafale fleet is not grounded waiting on engines with Dassault in full panic
 
you successfully proved to us that Rafale is not an ASF, so thank you for that.


I wonder who decided to make Supercruise the key factor between success and a suicide?
oh wait I remember:

but also:



:ROFLMAO:

and who continues to try and convince us the Rafale can supercruise in such a way?

We will discuss again in 2030, when the F-35 actually becomes fully operational.

Rafale above 18 km, 60000 feet.

Above 62000 feet is called the Armstrong limit. Beyond this altitude, you need a pressure suit or space suit 'cause your blood boils at regular body temperature due to low atmospheric pressure. Of course, the Rafale itself can maintain pressure inside the cabin, the suit is necessary when the pilot has to eject during emergencies.

Can the Rafale go beyond the Armstrong limit and operate up to 70000 feet? Yep.
Can the F-15C go beyond the Armstrong limit and operate up to 70000 feet? Yep. Almost the same climb rate.

Is it used in most operational settings? No. Is the same used on the F-22? No.

Pressure suits are heavy and limit the G performance of the pilot, so during AS missions, pilots only wear G-suits and stay well below the Armstrong limit in order to be ready for dogfights. So pretty much all ASFs maintain a 60000 feet altitude limit. A pilot can risk flying higher during emergencies, but that almost never happens.

All ASFs can operate above 18 km altitude, they just don't go beyond that outside of non-combat related missions or special missions.

PS: You cannot see the curvature of the Earth at 18 km. This curve is due to the camera's fisheye lens.

You know the difference between combat ceiling and trying some altitude test with half the fuel and being as light as possible?

So no one has answered me yet, will the US allow Brahmos to be integrated with F35 in case India goes for F35 ( hypothetically). Or the IAF will face crisis of source codes similar like integration of stand off munition into Rafales?
 
Nah, the Rafale has a better climb rate than the F-15C and comes with better aerodynamics for sustained climb rate, and even the F-15C can climb to 70000 feet. So it's a pretty normal altitude for ASFs.
Under what conditions can Rafail who is 0-1 possibly 0-3 in air combat reach 70k? Can it do it with missiles and tanks? How long does it stay at 70k?

If it's pretty normal how many times has Rafal gone 70k?

In the image I posted, you can see the Rafale carrying its signature 3 fuel tanks.

As for how long... let me put it this way, the F-22 will do worse at such altitudes than the Rafale 'cause its wings and control surfaces are smaller than the Rafale's, so the Rafale is going to be a lot more stable at such altitudes. That's also why it performs better than aircraft like the F-22 in the thin air of the Himalayas. It's also why the IAF like fighter jets with massive wings, like LCA and AMCA. The F-22 will have to use more thrust and TVC to fly stably, but that consumes more fuel than the Rafale, whereas the Rafale's flying up there with 3 tanks.

The fact that it could reach that altitude with tanks is testament to the fact that it can perform at the red line of human limits.

If it's pretty normal how many times has Rafal gone 70k?

Every pilot must have gone up at least once to the highest altitude they can during their training period. Pilot physical limits are the real constraint.

To understand this you first need the facts around it.

Operationally, there's no point in crossing the 50000 limit for long periods of time. Pilots experience immense strain at such altitudes. The reason why most aircraft list 50000 feet as the service ceiling is 'cause beyond that it gets difficult to breathe. As per USAF flight safety protocols, pilots have to wear a pressure suit if they are operating above 50000 feet. F-22 pilots are allowed to go up to 60000 feet with a pressure breathing system and a pressure vest. So even they need a pressure suit for altitudes beyond that. The same altitude the Rafale's at in the pic.

What’s perhaps less well-known about the F-22 is that getting it to its high-altitude perch of 60,000 feet — giving a 10,000-foot advantage over most other fighters — requires an ensemble of special g-suit and inflatable pressure vest, as well as mask and helmet modifications to ensure oxygen flow even if the canopy is jettisoned.

So JB's bragging about a 60000 feet ceiling. And it's due to the special modifications to the G-suit and oxygen system (OBOGS) versus others who are stuck at 50000 feet (USAF regulations) with regular G-suits and oxygen cylinders. But Rafale pilots too wear such special G-suits and have pressure berathing systems (OBOGS) for use at 60000 feet, like the F-22. Any aircraft with OBOGS can safely operate up to 60000 feet with only a G-suit for short durations. This applies to the F-22 as well.

ASFs typically zoom climb from a standard 12 km (40000 feet) to 18+ km during interception missions, fire their missiles, and then drop back down to 12 km, ready to repeat in case of a miss or are ready to dodge any incoming missiles instead of staying high up in the air like an idiot waiting for decompression sickness to set in. This applies to the F-22 as well.

Breathing is difficult at 60000 feet because you are not breathing normally, the OBOGS is giving you CPR and you are fighting back against that pressure as the system pushes air into your lungs with a lot of force. Pilots can sustain this only for a few minutes at a time before fatigue sets in, 5-15 minutes depending on what you are doing. Pilots' words: "Feels like breathing through a straw while someone squeezes your chest." And the mask fits tightly to your face, so when pressure increases, it feels like someone's grabbing your mouth with force while funneling air down your throat. So pilots do what needs to be done at high altitude and then quickly descend to below 40000 feet, or even 30000 feet, where you can finally breathe normally.

So the only way to operate comfortably at altitudes above 50000 feet with oxygen cylinder and 60000 feet with OBOGS is by using pressure suits and space suits, but that prevents you from getting into dogfights. That's why the Russians use a separate interceptor type (Mig-25/31/41) where the pilot flies with a space suit and the jet is incapable of dogfighting. This is one of the main limitations of human pilots in favor of UCAVs.

Btw, IAF jets like MKI and Mig-29 can zoom climb to 70000 feet, and they are inferior in performance to the Rafale. So the Rafale can easily match that.
