Navistar Defense, LLC has received an award for $18.9 million from the Naval Facilities Engineering Command (NAVFAC) for 38 International 5000-MV heavy truck tractors (HTTs), including spare parts and training services, to support Navy Seabee transportation needs. The company’s first contract with the U.S. Navy includes three option periods for additional vehicle orders. The vehicles incorporate armoring solutions derived from the International MaxxPro Mine Resistant Ambush Protected (MRAP) vehicle. Units include a manual 18-speed transmission and a MaxxForce D 13-L engine. Similar 5000-MV HTT variants were used by the U.S. Army during two Persian Gulf Wars to transport tanks across the Northern Saudi Arabian Desert. Nearly 600 HTT units are currently in service with KBR and the Iraqi Ministry of Defense to support security and rebuilding efforts. Production of HTT vehicles are expected to begin in early 2012.
