Oshkosh Defense Awarded $346.4 Million to Modernize U.S. Army/Army Reserve FHTV Vehicle Fleet

Oshkosh Defense announced that it has been awarded delivery orders totaling $346.4 million from the U.S. Army Contracting Command – Warren to modernize the U.S. Army and U.S. Army Reserve fleet of Family of Heavy Tactical Vehicles (FHTV).

Under the delivery orders, Oshkosh will recapitalize Heavy Expanded Mobility Tactical Trucks (HEMTT) and Palletized Load System (PLS) trucks as well as manufacture new PLS trailers.

The Army FHTV fleet is designed to accommodate many mission packages, allowing it to support multi-domain operations as the battlefield continues to evolve.

“Whether they’re hauling rocket launchers and missile defense systems, or transporting mission-critical equipment, the HEMTT and the PLS will continue to be an integral part of the U.S. Army and U.S. Army Reserve heavy vehicle fleets for years to come,” said Pat Williams, vice president and general manager of U.S. Army and Marine Corps Programs for Oshkosh Defense. “As the military pivots its focus to near-peer adversaries, they can be confident that the FHTV fleet will continue to serve as a key enabler for combat missions,” Williams continued. “We look forward to supporting the Army’s modernization priorities now and well into the future.”

Since 1995, Oshkosh Defense has recapitalized over 13,700 HEMTTs and 3,400 PLS vehicles. According to Oshkosh, the recapitalized vehicles are rebuilt with the latest technology and safety upgrades and quickly returned to field operations with the same warranty and life cycle cost advantages of a new vehicle.

The U.S. Army’s FHTV fleet includes Heavy Expanded Mobility Tactical Truck (HEMTT), Palletized Load System (PLS) trucks and the Heavy Equipment Transport System (HETS) tank transporter tractor unit. Oshkosh Truck was awarded the FHTV contract in March 2001.

Heavy Expanded Mobility Tactical Truck (HEMTT)

The Heavy Expanded Mobility Tactical Truck (HEMTT) is the workhorse of U.S. Army combat divisions. It is the key combat service support enabler for all brigade combat teams. The 11-ton, eight-wheel-drive vehicle family is designed to operate in any climatic condition.

There are several basic configurations of the HEMTT-series trucks: the M977 cargo truck with light materiel-handling crane; M985 cargo truck with medium materiel-handling crane; the M978 2,500-gallon fuel tanker; the M983 tractor; the M984 wrecker; and the M1120 Load-Handling System (LHS) and the M983 Light Equipment Transporter (LET), used in Stryker recovery operations and movement of heavy engineer equipment. The M1977 Common Bridge Transporter (CBT) is a modified M977 HEMTT equipped with an LHS to support the Engineer Corps in transporting all bridging assets.

M1075A1 Armored Palletized Load System (PLS)

The Palletized Load System (PLS) is the primary component of the maneuver-oriented ammunition distribution system. It also performs local-haul, line-haul, unit resupply and other transportation missions in the tactical environment. In addition, the PLS is the prime mover for the M7 Forward Repair System and various engineer mission modules (M4 Bituminous Distributor Module, M5 Concrete Mobile Mixer Module and M6 Dump Body Module). The PLS is the host chassis for the dry support bridge launcher vehicle (M1975).

The PLS consists of a 16.5-ton payload tactical truck with a flatrack. It is a five-axle, 10-wheel drive vehicle with a 500-hp Detroit Diesel engine, an Allison automatic transmission and a CTIS.

The PLS comes in two mission-oriented configurations: the M1074 and the M1075. The M1074 is equipped with a variable reach materiel-handling crane (MHC) to support forward-deployed field artillery units. The M1075, without MHC, is used in conjunction with the M1076 trailer to support transportation line-haul missions.

M1076 PLS Trailer

The M1076 PLS trailer is a three-axle, wagon-style trailer with a 16.5-ton payload capacity that is equipped with a flatrack that is interchangeable between truck and trailer. The combination of truck and trailer provides a combined payload capacity of 33 tons.
