Defense Acquisitions: Department of Defense Needs a Unified Strategy for Balancing Investments in Tactical Wheeled Vehicles

Correspondence issued by the Government Accountability Office with an abstract that begins "Ground-based military operations generally make use of two broad categories of vehicles: combat vehicles designed for a specific fighting function and tactical vehicles designed primarily for use by forces in the field in connection with or in support of tactical operations. Combat vehicles generally move on tracks versus wheels and include the Abrams tank, Bradley Fighting vehicle, and the Paladin self-propelled howitzer. Tactical vehicles generally move on wheels and include the High Mobility Multi-purpose Wheeled Vehicle (HMMWV), the Mine Resistant Ambush Protected (MRAP) vehicle, and families of trucks and trailers. For fiscal years 2009 and 2010, the Department of Defense (DOD) has requested an estimated $16 billion for the procurement of those tactical wheeled vehicles described in this report, including an estimated $6 billion for MRAP variants. In June 2007, Congress requested that we assess (1) the extent to which DOD had developed an overall tactical wheeled vehicle (TWV) investment strategy that considers timing, affordability, and sustainability; (2) the extent that the programs in the strategy fill identified gaps or provide duplicative capabilities; (3) the current status of selected tactical wheeled vehicle systems that are a part of this strategy; and (4) whether DOD is pursuing a knowledge-based acquisition1 approach as a part of this strategy. On the basis of discussions with your staff, we initially focused on gathering and analyzing data related to the MRAP program. We provided the members of your staffs with a series of briefings between September 2007 and March 2008, and summarized the results of our MRAP work in a July 2008 report. Shortly thereafter, and on the basis of additional discussions with your staffs, we resumed the work related to our overall assessment of tactical wheeled vehicles and provided an interim briefing on the results of our work on April 30, 2009. For our assessment of the current status of selected tactical wheeled vehicle systems, we included the following systems: MRAP; MRAP-All Terrain Vehicle (M-ATV) variant; HMMWV Expanded Capability Vehicle (ECV) variant; HMMWV ECV2 variant; Joint Light Tactical Vehicle (JLTV); Armored Security Vehicle (ASV); Family of Medium Tactical Vehicles (FMTV); and, Heavy Expanded Mobility Tactical Truck (HEMTT).
