1995 Supporters contend that the F-22 can also be used in an air-to-ground role. However, the Congressional Budget Office concluded in a February 1995 report that the F-22's utility in this role would be far less than that of an aircraft designed specifically for that mission.
The Congressional Budget Office report entitled "Reducing the Deficit" concluded in February 1995 that cancellation of the F-22 program would result in a five-year savings of $14.5 billion dollars. The CBO's primary reason for the cancellation option is that the F-22's additional capability is both unnecessary and too expensive.
The Critical Design Review (CDR) of the F-22 and the Initial Production Readiness Review (IPRR) of the F119 engine were completed in February 1995. The Air Force confirmed that the program was ready to proceed to fabrication and assembly of EMD aircraft.

Supporters of the F-22 are expected to try and add $200 million to the military budget in fiscal year 1996 to avoid delays in the F-22 program. The Air Force originally requested $2.3 billion for fiscal year 1996 for the F-22 program, but the Pentagon reduced that to $2.1 billion. This follows a $110 million cut by Congress in the 1995 budget request, and $163 million in the FY 1994 budget plan.
