Well, the Senate Appropriations Committee cut funding for the F136 alternate engine for the JSF, though the committee chair, Daniel Inouye (D-HI) has made it clear that he wants it back when the conference report comes out.
In any case, it’s clear that the White House’s opposition to continuing work on an alternate engine is soft, as the discussions between the Pentagon and GE/Rolls on a firm fixed price for the engine, are continuing, and GE is promising a, “formal unsolicited Fixed Price offer,” in the next week or so.
I’m not sure if the DoD is seriously looking at proposals, of if they are just trying to browbeat Pratt & Whitney though.
