US Marine Corps Logistics Vehicle System (LVS) Mk-48 Front Power Unit (FPU)

The Mk-48 Front Power Unit is an all-metal, fully enclosed, diesel powered, automatic transmission, 4x4 tactical truck that provides all automotive and hydraulic power for the LVS combinations. The MK48's low-profile,cab-forward configuration permits loading aboard military aircraft with no preparation. The front power unit and rear body units are joined by a hydraulically powered articulated joint that assists in steering the vehicle and allows a degree of independent movement between the front and rear units for more mobility. The articulated joint transfers automotive power to the RBU axles and hydraulic power for any hydraulically operated equipment. The completed units form an integral, dual body, fully articulated,8x8 vehicle with cross-country mobility. The MK-48A1 variant has minor improvements to the design.

The full nomenclature of the Mk48 FPU is Power Unit, Front, 12-1/2 Ton, 4x4, MK48, MOD O, NSN 2320-01-177-5167.
