Citat:CRS: Alt-Engine Could Reduce U.S. F-35 Buy

Continued funding for the F136 alternate engine for the F-35 Lightning II fighter jet is likely to reduce the number of jets the Pentagon can buy unless the program receives more money, according to a March 22 report by the Congressional Research Service.

"If alternate engine funds are allocated within the existing F-35 budget lines, other F-35 activities must be curtailed in favor of the alternate engine program," says the report, titled "F-35 Alternative Engine Programs: Background and Issues for Congress."

The report cites U.S. Marine Corps Maj. Gen. David Heinz, a former manager of the Joint Strike Fighter program, as saying that keeping the alternative engine program alive could force the Pentagon to cut 80 jets from the planned U.S. order of 2,443.

The report also warns against simply increasing the amount of money in the JSF program in order to buy the General Electric-Rolls Royce F136.

"Increasing the F-35 top line to account for the effects of increased alternate engine funding without" a similar increase in the Pentagon's total budget "would force the transfer for funds from other defense programs to the F-35," it says.

The Pentagon zeroed funding for the F136 in its 2011 budget request, but lawmakers continue to fight for the production of the second engine, arguing that the competition will improve contractor performance and provide a safety net against problems with the Pratt & Whitney F135 engine.

Pentagon officials have said numerous times that the second engine would be a distraction to a program already beset with delays and cost overruns. They say there is no financial justification for buying a second engine

"JSF has present serious shortfalls in engine performance and incomplete sensor-fusion capability," the DSTO said.

"The aircraft lacks engine thrust in the baseline configuration due to the high weight, affecting the use of manoeuvrability to defeat missile attack."

It also warned of hi-tech risks in the program because of tight schedule and cost targets, but it gave the plane strong marks for its stealth, range, payload and its "all weather, 24-hour lethality".

It said the JSF would not be cheaper to acquire than other fighters, but would be cheaper to maintain and service.

Despite these criticisms, the study recommended narrowing Australia's choice of a new fighter jet to only three: the JSF, the American F-15E and the French Rafale.

Znaci, i Australija je malo poljuljana sto se tice nabavke F-35
Nadam se da ce se ta poljuljanost pretvoriti u pravi "razorni zemljotres" pa da ga uopste i ne uzmu!

Rafale-u zelim svu srecu!

To je studija jos iz 2000. Naucnici su dosli do zakljucka da je Tajfun nepouzdan i da nema adekvatne V-Z mogucnosti. Jasno je da je dosta uradjeno na tom planu od tada. Takodje su radrski odrazi 4+ generacije aviona umanjeni. Daleko od toga da su stelt. Posto su Gripena onako odbacili kao ne-stelt.

kako ameri misle da plate ovih 2000 komada.

Mozda je 2000 komada ukupna proizvodnja za sve zemlje koje ce ga kupiti , ne samo za SAD ?

Ako sam dobro zapamtio samo SAD-u treba da bude isporuceno oko 2300 i nesto komada, to je bez ostalih narucilaca.
