Buying defense weapon systems under multiyear contracts rather than a series of single-year contracts can save costs because contractors can buy materials in more economic quantities, schedule workers and facilities more efficiently, and reduce the burden of preparing multiple proposals. The U.S. Air Force is in the process of awarding multiyear contracts for 60 F-22A aircraft over three years. Congress wants to assure itself that the proposed contract will yield the promised savings and asked RAND for an independent review of the estimated savings. Researchers found that a multiyear procurement of three lots of F-22A fighters would save an estimated $411 million-about 4.5 percent of the total contract value. They were able to trace 70 percent of the $411 million to substantiated savings estimates identified by the contractors. Examining the issue of multiyear savings using several approaches produces a consistent range of results, indicating that the savings attributed to the multiyear contract by the contractors appear to be reasonable.

This report examines how well DoD is planning and executing its weapon acquisition programs. The report includes: (1) an analysis of the overall performance of DoD's 2008 portfolio of 96 major defense acquisition programs and a comparison to the portfolio performance at two other points in time -- 5 years ago and 1 year ago; (2) an analysis of current cost and schedule outcomes and knowledge attained by key junctures in the acquisition process for a subset of 47 weapon programs -- primarily in development -- from the 2008 portfolio; (3) data on other factors that could impact program stability; and (4) an update on changes in DoD's acquisition policies. Includes a one- or two-page assessment of 67 weapon programs. Illustrations.
