Additionally, for the short term, a number of commercially available materials and technologies can be used for Army trucks, including high-strength and stainless steels, aluminum and magnesium alloys, and MMCs. Manufacturing processes available today include superplastic forming, castings of aluminum and magnesium alloys, and the use of tailor welded stamping/forging blanks.

. FUTURE TACTICAL TRUCK STRATEGY The Army truck fleet continues to degrade faster than it can be upgraded through new acquisitions, forcing the Army to use recapitalization techniques simply to maintain the fleet size and effectiveness ratio.t While this approach permits the possible introduction of improved components such as the engine, it renders almost impossible advances in overall vehicle configuration and structural architecture or the introduction of new lightweight materials.

In order to reduce the technology development cost burden typically placed on an individual vehicle program, the strategy should also establish a broad technology development program plan. Atechnology development program should be based on a budget process that prioritizes new technology development.

RECOMMENDATION. THE ARMY SHOULD MODIFY ITS BID SOLICITATION AND PROCUREMENT PROCESSES TO STIMULATE AND REINFORCE DESIRED REACTIONS, INCLUDING: · The Army should clearly define the performance attributes that are important in its use of trucks.

The emphasis of participants from the commercial automotive industry on the affordability of new materials, such as titanium, magnesium, and polymer matrix composites, should greatly facilitate prudent investment decisions by the Army. By working more closely with university centers of excellence, the Army can identify new enabling technologies in lightweight materials and in sensing and health monitoring, and it can also fund demonstration projects.

The cradle-to-grave research and development for processing, assembly, service, remanufacturing, and operator training, which is currently done primarily within the Army, should be shifted to establish a more collaborative approach with these material and component suppliers. SYSTEM FOR TRACKING VEHICLE AGE AND CONDITION Army trucks are kept in service far beyond their economically useful life, resulting in increased operations and support costs and decreased performance.

TRACKING NEW MATERIALS FOR REPAIR AND DISPOSAL The majority of material used in Army trucks today is plain carbon steel. The corrosive galvanic current between two plain carbon steel parts placed in contact will be small and may not cause serious corrosion.
