That depends on the price tag you put on your pilots' lives and ultimate outcome.
There is a level of acceptable risk and there is unacceptable risk. The EF was never designed for supercruise. It just flies fast, that's all.
Well, EF is more than just a little faster.
Anyway, for the plane of its size, it's more than a serious threat to long range fighters.
And I'm not quite sure if Flanker can make 25 minutes on full AB @40k ft and M1+.
Theoretical limit at @40k ft and M1+ would be ~14 min.
In reality it's something like 8-10 min, so you see a speed difference of M.3+ is a very useful thing to have.
I got my info from pilots, but this time includes merge and a dog fight with full AB. Let's not forget the fact that MKI carries twice the fuel EF can and the engine is not twice as powerful. At full AB, the MKIs fuel fraction is greater than most other fighters, or at least the F-100-220. There is no theoretical limit on AB time. It all depends on engine life and fuel load. Bombers manage more as well.
The F-15C manages a 10 minute AB time I guess.
Yes, Mig31 is even more useful in that sense.
Anyway, vast majority of air combats begins with interception, to the point that you can count on it.
However, I'm talking about same class of airplane here, EF and Rafale and Mig31/Su30 are something else.
Yes. Even if we remove the Russian and American aircraft from our discussion, the difference between Rafale and EF is very small in most parameters. Rafale's engine is powerful enough to manage supercruise at half fuel and air to air loads. Supercruise was never really a selling point. I mean to say no pilot will buy a EF/Rafale because it can supercruise at Mach 1.2. It is not a design advantage. Any aircraft with powerful engines will do Mach 1.2 and this includes Rafale, Gripen, LCA, EF and Su-35. Stick the 117S into MKI and there won't be much of a difference. Ultimately all these aircraft will still fly at subsonic speeds because once you add bombs supersonic will be moot.
Currently only PAKFA is being designed to release bombs at supersonic speeds. Other aircraft won't even manage above Mach 1 on a decent day. Tell me that EF can do Mach 1.5+ with 2 JDAMs then I will buy the claim. Mach 1.2 with 4 AAMs isn't supercruise. There are limits to supercruise when the design does not allow it. Only F-22 and SR-71 are supercruise capable. The F-22 has a modified engine nozzle while the SR-71 had modified air inlets. EF and Rafale have neither except for powerful engines.
Although this isn't addressed to me, I still think it's worth noting.
There are no fighters built against bombers or fighters...fighter plane is a fighter plane.
I believe you're thinking of multirole and singlerole fighters.
However, don't forget that it was Mig25 that scored a kill on US F18 in Iraqi war and overall posed most troubles for Americans.
Not Mig29s, or Mirages.
We can't use Iraq war as as reasonable justification to determine the quality of Soviet equipment of the time. Other than the fact that export models were downgraded, the Iraqis never gave a fight.
When the Mig-25 was first revealed to American planners. They thought the Soviets had one upped them on the fighter front. So, they assumed that will be SU's primary air superiority fighter. The basic design suggested the Mig-25 would have awesome maneuverability. Then they found the Flanker a little while later. Satellite pictures revealed a much superior fighter. Pretty soon they realized that the Mig-25 was actually an interceptor which is incapable of high G maneuvers. The Mig-25 was designed only for two purposes, interception of high speed bombers and recce. The very concept for interception is to fly fast and kill bombers before they launch nuclear devices. The F-14 was very much the same. Once the design outlived the need, they were replaced by more capable strike fighters(F-18s), which is the current mantra for air combat, strike capability.
During the cold war, each aircraft built had a task cut out for it. Air superiority fighters engaged interceptors, strike and other air superiority aircraft. Interceptors engaged bombers. Strikers engaged ground targets and ships while recce aircraft like U-2 were used for intel.
Americans had the F-15 for air superiority, F-14 for interception and F-16 for strike. F-18 replaced F-14s later on. The Soviets had Mig-25/31 for interception, Su-27/Mig-29 for air superiority and a number of older strike aircraft. In the days of satellites, Interceptors have always been used against bombers and, presently, cruise missiles.
