My answer to Who in the government decides what weapons to buy for the military?
Answer by Ken Larson:
The Defense Systems Acquisition Review Council (DSARC) overseas a rigidly controlled level of review from initial development through production.
U.S. Government Accountability Office (GAO)
“The Defense Systems Acquisition Review Council (DSARC) advises the Secretary of Defense on the acquisition of major defense systems, reviews the status of individual programs, and formulates recommendations to the Secretary of Defense. It has conducted over 178 reviews since it began in 1969, and some programs have required successive reviews.”
Congress incrementally approves funding for all weapons on a fiscal year basis. If weapons systems do not receive ongoing funding they are not acquired. The picture below is an example of some systems and programs that are now seriously under review in terms of a funds vs. benefits trade offs:
