Fighter plane program may see cuts to pay for backup engine

The number of fighters may be lowered by 50 to 100, out of about 2,500, to pay for a second engine.

Lockheed Martin Corp.'s F-35 Joint Strike Fighter program might be cut by as many as 100 aircraft if the Pentagon is forced to restore a backup engine made by General Electric Co. and Rolls-Royce Group Plc, according to the Air Force general who manages the program.

"If the money comes out of JSF, we'll trade airplanes to pay for it,'' Air Force Brig. Gen. Charles Davis told Bloomberg News in an interview this week. "That's our only source of dollars."

Davis said the number of fighters may be lowered by 50 to 100, out of about 2,500, to pay for a second engine. The House and Senate fiscal 2007 Defense appropriations bills would restore the F-136 backup engine -- which the Pentagon wanted to terminate to save about $1.8 billion through 2011.

The purchase of the first plane, dubbed the F-35 Lightning II, already may be pushed back by more than a year to allow for additional testing after the Senate Defense Appropriations Subcommittee, responding to concerns from the Government Accountability Office about the adequacy of the initial test schedule, cut $1.2 billion from the procurement budget.

Davis said the cuts, if sustained, will lead to a delay of about 20 months, likely driving up costs. The first flight, originally scheduled for this month, will not take place until November because of "frustrating" technical issues, he said.

Lockheed, the largest U.S. defense contractor, is leading the program while United Technologies Corp.'s Pratt & Whitney unit is the primary engine supplier. The Pentagon was told by Congress in 1995 to develop a second engine to maintain competition, lower costs and have an alternative should technical problems arise.

The Joint Strike Fighter, estimated to cost $250 billion to $276 billion, is the Pentagon's most costly weapons program.
