B-1 STRATEGIC BOMBER

Funding

Fiscal Year 1975 and Prior Years:

 $2.027 billion

Fiscal Year 1976:

$  661 million

Cost Data

In the absence of inflation, B-1 costs have changed very little since the program went on contract in 1970. The initial program estimate of $9.9 billion is now $11.1 billion - an 11 percent increase or about 2 percent a year. Inflation through calendar year 1976 has added $5.7 billion to the total program costs, making it $16.8 billion in 1976 dollars. If inflation is forecasted through program completion in the mid-1980s, total program cost is estimated to reach $21.6 billion in "then year" dollars.

The following tables show current program cost estimates in "no-inflation" 1970 dollars, current 1976 dollars, and in forecasted "then-year" dollars. (Procurement unit cost is the average cost to produce an aircraft (airframe, engines, avionics and other government-furnished equipment), the peculiar cost to deploy one aircraft (ground support equipment, training equipment, etc.) and the cost of initial spares. Program unit cost includes the development cost amortized over the total number of aircraft (244) to be built.)

The bulk of increases to the Air Force B-1 cost estimate (some 89 percent) has been due to the effects of economic inflation. Forty-nine percent of the total program cost estimate is inflation.
