Well you're free to believe what you like if it makes you feel better when attacking the Euro products but I need not go any futher with this as Scorpion said it all.

Europe didn't want a 5th gen fighter (or perhaps more precisely the cost of one, even if the EF-2000 isn't much cheaper in the end), that's what it comes down to.

They couldn't have made one in the EF program time frame if they'd wanted to.

That is oversimplified nonsense and if you would be intellectually honest you would know this and deal with the true requirements knowns for these aircraft, rather than reducing everything to a single factor to draw a wrong conclusion which suits your mind.

The ATF was designed to replace a single type in a single role with a single customer, or in other words to replace the F-15A-D in the airsuperiority role with the USAF.
The ATF was required to be able to kill enemy aircraft over their own territory long before they would reach allied territory. This meant that the aircraft had to be able to operate over the densest most sophisticated IADS at that time. Stealth and supercruise were crucial to achieve that goal and the direct result of very specific requirements.

The Typhoon on the other side was designed to replace a number of types in different roles with different services. The aircraft had to fulfill a secondary AG role, it had to be cheap enough to be procured in adequate numbers and as an air defence air superiority platform the Typhoon was not required to deeply penetrate the enemy airspace. The budget was smaller as well and there was less overspending at the end with a significantly lower per unit programme cost.

So no the requirements weren't the same.


You preach to Shep about intellectual honesty aND then you got the nerve to make a statement like that about the cost of the EF? There is nothing even remotely cheap or significantly lower cost per unit about the EF. Regardless of how good or bad the EF may be, it most certainly is not cheap!

Here is the the link to a comprehensive report about the T-50.

Thursday, June 10, 2010
AFA members, Congressional staffers, Civic Leaders, and DOCA members, back in January I told you about the first reported flight of the Russian Federation's fifth-generation fighter, the PAK-FA. The attached 74 page briefing, dated 2 Mar 10, by David Markov and Andrew Hull is full of interesting pictorials, facts and figures. It's a large file (over 5 MB). And … all should know that it is gleaned from unclassified sources. I again repeat what I said last January. Do you think the Russians will stop at building 187? How many do you think they will sell to their customers? You can find the piece at:

The Euros will always fall back on justifying all of their projects as jobs programs. The fact is the F-15 would have been a more cost effective solution but wouldn't have preserved their design and industrial capabilities for wars they are never going to fight anyway. The US has actually recognized the F-22 is unsuited for the 21st century wars we're likely to fight while the EF partners are obligated to buy something they don't need or in some cases even want because of the agreement they signed.

The Europeans could have an affordable multimission aircraft if they all agree to what that means.

Better read more carefully before hitting the reply button in anger. The programme cost spread over the number of airframes is actually much lower for the EF in comparison to that of the F-22 and even if you are just comparing the fly-away prices the EF is still a fair margin cheaper. The only thing which made the EF more expensive in the US centric view was the currency exchange rate between € & $.
That doesn't mean that the EF is cheap at all and I didn't said so either. What I said is that from the requirements the aircraft had to be cheap enough to be procured in adequate numbers.

Which we all know it wasn't. You've only got to look at the gimped RAF force to see that and add to that it was four and half years late! Also we were so desperate to make some money back on the over spending that we had to sell some to Saudi Arabia because the program costs ran so high.
The costs doubled and now the MOD are so embarrassed by the financial fiasco that was Typhoon they won't even release any figures!

The officical story is slightly different from how you tell it...

This is a huge misconception. As an example the F-117 was considered to be a waste of money for a cold war that never turned hot. Then Gulf war 1991 happened and look what they said about the plane from then on.

The truth is that you never know what kind of conflights the 21 st century will see. Every body wants to go to the doctor only when their sick. Wrong. Smile
Be prepared.

The reason why some contries fulfill contracts that they want no more is because due to the fact that, at the time of accpetance of the hardware, the goverment has to include the financial deficit and publish those results, and that does not bode well for the votes in these times. Simple as that.

Rest assure the same military expenditure critics will come about criticizing why the country failed to respond properly to any crisis.

It's easy to judge about things afterwards, back in the 1980s no one could have predicted how things would run. At that time the Cold War was a reality, that it would be over in just a few years was not foreseen during the planning phase. The bulk of the delays is in fact owed to politics and its politicians who now complain about the delays. And delays lead to cost increasings about which they complain as well. That's not to say that there weren't other reasons for delays and cost increases, such as technical difficulties, changing requirements etc.
Defence budgets are getting smaller and smaller, at the same time there are military commitments which cost a lot of money so you have to start cutting. The aircraft is certainly expensive and it's more expensive than it should have been, but you have to take the reasons for that into account as well. Your beloved F-35 is neither on time nor on cost either, total estimated programme costs are now about twice of what has been projected and average fly-away is 2.5 - 3 times higher and that's not the end of the story. The same is true for the F-22. That doesn't make the situation better for the Eurofighter, but puts things into a perspective. Criticising one project for being late and over budget, but ignoring the fact that others share the very same fate is somewhat one sided.

According to http://en.rian.ru/russia/20100617/159462165.html Sukhoi T-50 will be superior to F-22 in maneuverability, weapons and range. Also in ... morale (people, please don't laugh).

These would appear to be the least challenging/costly capabilities to achieve. So they could just as well be describing a SU-35, albeit with internal weapons carriage. I wonder how the laatest Flanker and PAK-FA would match up with one another?

That, and it's not even a given that the Su-35 is more agile than the F-22.
I have no doubt that the T-50 will have impressive kinematic performance, but it's silly at that this point of testing to speak in such absolute terms.

Not more silly than assessing the aircraft's RCS. You can at least assess what is visible. With its second stage engine the PAK FA will likely offer greater kinetic performance than the Raptor, at least in terms of afterburner speed due its smaller control surfaces and higher sweep angles. Whether the supercruise performance will be comparable or better will much depend on the engine thrust output on dry thrust at high speeds and altitudes. A higher manoeuvrability is likely as well given the lifting fuselage design, LEX and possibly higher degree of instability.
