The Maritime Prepositioning Force (MPF) Utility Boat (MPFUB) is a commercially designed utility craft used primarily to move personnel and light equipment during MPF offload operations. The 41 foot long, high-speed landing craft are replacing the Navy’s existing LCM-8 craft as part of the United States Navy's Improved Navy Lighterage System (INLS) in support of pre-positioned Marine Amphibious assault missions. Additional missions include supporting waterborne force protection, transportation of personnel and materials, medical evacuation, salvage, damage control, and repair operations.
