Assessments of Selected Weapon Programs

March 29, 2012

The total estimated cost of the Department of Defense's (DOD) 2011 portfolio of 96 major defense acquisition programs stands at $1.58 trillion. In the past year, the total acquisition cost of these programs has grown by over $74.4 billion or 5 percent, of which about $31.1 billion can be attributed to factors such as inefficiencies in production, $29.6 billion to quantity changes, and $13.7 billion to research and development cost growth. DOD's portfolio is dominated by a small number of programs, with the Joint Strike Fighter accounting for the most cost growth in the last year, and the largest projected future funding needs. The majority of the programs in the portfolio have lost buying power in the last year as their program acquisition unit costs have increased. The number of programs in the portfolio has decreased from 98 to 96 in the past year and, looking forward, is projected to decrease again next fiscal year to its lowest level since 2004.

In the past 3 years, GAO has reported that newer programs are demonstrating higher levels of knowledge at key decision points. However, most of the 37 programs GAO assessed this year are still not fully adhering to a knowledge-based acquisition approach. Of the eight programs from this group that passed through one of three key decision points in the acquisition process in the past year, only one—Excalibur Increment Ib—implemented all of the applicable knowledge-based practices. As a result, most of these programs will carry technology, design, and production risks into subsequent phases of the acquisition process that could result in cost growth or schedule delays.
