@ww,
the F-35 won’t fly with M 1.6 on a regular basis either. The point is to be able to reach moderate supersonic speeds in a short enough time frame.

Cola, JJ was trying to say that if it takes 2xF414s ($8.6mil) to equal the thrust of 1xF135 ($13.6mil FY2011). Therefore the F414 (2x at 44k lb thrust) cost is $195/lb vs the F135 (1x at 43k thrust) at $316/lb, a 61.7% increase in cost per lb over the F414.

Now the fun part. The F135 will continue to drop in price (the above mentioned 250th F135 will be in 2015).

And lastly, the F135 will likely have a lower SFC (.886 dry) than the F414 (.840 dry, double this for two engines = 1.680). This will lead to much lower fuel costs over the life of the engine for the F135.

Well the SFC is in fact higher according your data and the engine is less economical by that than the F414 or other contemporary designs.

13061 kg * 0.886 = 11572 kg of fuel per hour on max dry at SL
2×6300 * 0.840 = 10584 kg of fuel per hour on max dry at SL

In other words your single F135 consumes 988 kg more fuel, while providing 461 kg more thrust than two F414!

@jj,
well I have listed the supposed fly-away prices a couple of times now:
T1 = 53 mln € (German price without VAT)
T2 = 55 mln € (according the contract value for 236 aircraft)
T3A = 58-59 mln € (according Eurofighter)

Up to date there isn’t much out about how T3A aircraft will be configured. It’s also not said that the T1 & T2 examples will be upgraded to T3A, just that they will be upgraded. Anyway this is the wrong place. If you want to know more, I’ll post in an appropriate thread.

yes the t2 was wrong, it was the t3 he said was 58-59m, i guessed he was talking pounds and not euro’s as we were talking UK and said ~60m pound, it obviously wasnt the 67m pound contract price
~ = about
ok, all you need to do is a NETMA link to your claim of 42m

And why do you guess that I meant pound when I wrote Euro (€)? The 58-59 mln € figure per T3A aircraft was reported by Jon Lake and the source quoted was Enzo Casolini, CO of the Eurofighter GmbH.
The 9.1 bln € T3A contract figure includes 2.5 bln € for upgrading T1 & T2 examples as well.
59 mln € * 112 = 6.6 bln € + 2.5 bln € = 9.1 bln € the quoted contract price!

I thought that GB paid almost 70 mln £ for the Eurofighter.

This is not the fly-away figure. When the T2 contract for 236 aircraft was signed on 14th december 2004 it was valued at 13 bln which makes an average 55 mln € per airframe. A German government request asked for the price of the “current” Luftwaffe Eurofighters and the answer was 57 mln € with VAT and 53 mln € excluding VAT. The T3A price has been quoted with 58-59 mln € according Enzo Casolini the Eurofighter GmbH CO. It’s important to take into account what is included in the price. Dunno whether the F-15SE price tag includes anything else bare the aircraft with its systems.

@Pioneer,
the original LFI programme was cancelled in 1992, but a new programme was launched in 1994 this was dubbed LMFS, but got cancelled as well in favour for the PAK FA programme in 2001. The Russians didn’t have the funds to pay for both projects, PAK FA replaced the MFI programme which was ceased in 1997.

The designation MiG-33 has been used two times now and MiG attempted another reuse of this designation. I’m sceptical that they would use this designation once again, especially for a new type after the MiG-35. But the Russians will have enough to do anyway to develop and field the PAK FA, so don’t hold your breath. It has been stated that there will be a hi/lo mix comprising PAK FAs and Su-35s as well as MiG-35s (though the latter isn’t yet on order).
