He's a defense author, pretty much made the same case you did, and with the exact same two-pronged explanation. Although it is something obvious enough for several people to come up with of course. Took a shot and missed.

The problem with just going for the above number is that they came from a 90s DERA analysis, with unknown assumptions, but it is not hard to see that the Typhoon's advantages are less robust than the F-22.
The specifications for the F-22 roots back in the 70s.

Might also remember that 2-2.5 times poorer kill ratio means 2-2.5 times more planes that won't ever fly again, regardless of the maintenance time you dump on them.
But the F-22 makes any oplane lost more hurting , since it costs more and the enemy can buy more polanes for the same money. A power depending on maximum-priced platforms obviously suffers greater damage from the same ammount of numerical losses than a power using less precious sytems. the first needs to achieve a higher kill ratio therefore, to compensate for that. But as I said, the redcued time-in-air also plays into the - admitted: abstract and academic - comparison.

Not too mention that those kill ratios found in that SU-35 simulation are, like any military exercise and analysis, not beyond disucssion.

There are also the problems of SAM penetration when facing a first-rate power, and here the difference is one of being engagable versus unengagable (at least with current tech). The Eurofighter IIRC has a cruise missile class RCS or something similar, which in the modern SAM world might as well mean it wasn't stealthed at all.
As you said: against a first-rate power. the argument is that a conflict against a first rate power is extremely unlikely, and the kind of wars we have seen since WWII and in the present and will see in the forseeable future are no conflicts against firtst rate powers. The F-22 is a overpriced system for a type of war that will not be.

Indeed the Obama admisnitration plans a slight increase if defemnce spendings over the medium and long range. to say they just cut spendings, is nonsense. Instead they try to cut what is not really needed but still costs a lot of money - and still increase spendings. And this with 12 trillions in debt, a bad budget and trade totally off balance. I think that system tries to declare insanity a virtue and tries to cure the disease by redefining sickness as a state of relative health.

350 million plane a piece?

Soon enough the US Air force could only afford to deploy ONE plane to war!
That must have been a hell of a plane!:rotfl:

300 million $ including R&D costs.
Really the airplane costs "only" 130 million $ I think, still a lot more money than any previous aircraft.

Yea but it looks cool. If there is no war it will be nice to look at it in air shows etc.

To be exact:

Over the four-year period, the F-22's average maintenance time per hour of flight grew from 20 hours to 34, with skin repairs accounting for more than half of that time -- and more than half the hourly flying costs -- last year, according to the test and evaluation office.
The positive way to look at this is that if they gave up skin repairs, they can cut the time by half. Obviously, if the stealth skin deteroriates, stealth would suffer, but materials are only half of stealth (around 20dB) worth with the rest being shaping.
Thus a wartime expedient might be to just give up maintaining the stealth coating. The F-22's "total stealth" is somewhere in the -30 to -40 region. Even if its effectiveness thus falls to zero, it would only be a 20dB deteoriation and it'll be a -10 to -20dBSM aircraft, which still makes it stealthier than a "prime condition" Typhoon.
The stealth skin would seem to be materials not living up to its promise, and thus it is doubtful a permanent fix can be found. As for the rest of the problems, they don't seem to be problems that can't be solved ... eventually.

See above.

Don't know what you are trying to say here. What I was trying to say is that tech has advanced since the mid-1990s, and not in a way particularly friendly to stealth aircraft, which means even if we assume DERA was 100% accurate in its estimate in 1990s, by now the estimate would have slewed to a much lesser advantage. It is not hard to guess where the advantage was for the EF and F-22, and not hard to see that the F-22 has broader (more multidimensional) and deeper (more superiority margin), which means it would have lost less of its estimated edge.

Of course, but frankly, I don't see a whole lot of possible arguments that would make things chummier for the Typhoon relative to the F-22 or the Su-35 int erms of performance.

I don't disagree that the United States will do well to reduce its total military budget. GIVEN a particular budget, however, I don't see cutting the F-22 program as the way to go despite its travails, especially since the JSF program isn't going so swimmily itself.
As for retaining optimal ability for dealing with first-rate powers ... the average citizen and politician (and even some politically motivated general) might want to optimize their military so they can use it to kick ass against weak countries more often and get some "Return on Investment", even if it means sacrificing some ability on the high end. It must not be forgotten, however, that the military is ultimately an insurance policy against the unlikely, but dangerous threat of the "high-end war". Intervening against weak nation might be nice and probable but probably isn't quite vital to the nation's interest. A strong nation is much more likely to actually hold a vital interest. Is it wise to gamble away the ability to prevail here, however unlikely, to improve ability to kick ass in more probable but ultimately less dangerous "Low intensity" conflicts?
Less than optimal arrangements for LIC means some extra blood. Less than optimal arrangements for HIC might mean losing the war. America's choice...
