The Product Director Light Tactical Vehicles (PdD LTV), is responsible for the Army’s High Mobility, Multipurpose Wheeled Vehicle (HMMWV, pronounced “Humvee”) family of vehicles, the Light Tactical Trailer (LTT), the M200A1 2.5-ton Flatbed Trailer, the M1061A1 5-ton Flatbed Trailer, and the Light Engineer Utility Trailer (LEUT).;The Army's requirement for Light Tactical Vehicles is currently 124,461, with unit authorizations expected to decrease over the coming years. A total of more than 250,000 HMMWVs have been built over nearly 30 years of production and are in service world-wide with the Army, other United States armed services, and foreign military sales customers.
The versatile HMMWV is the Army’s ubiquitous vehicle, providing a common, light tactical wheeled capability. The HMMWV is the Army’s (and other Services’) primary light wheeled vehicle for combat, combat support and combat service support missions. HMMWVs of all variants (but mostly up-armored versions) are currently deployed in support of operations in Afghanistan.
The HMMWV family of vehicles consists of multiple configurations built on a common chassis to support weapon systems, command-and-control systems and field ambulances, and to provide ammunition, troop and general cargo transport. It is currently equipped with a high-performance 6.5-liter turbo-charged diesel engine, electronic automatic transmission and four-wheel drive. It is air transportable and low-velocity airdrop (LVAD) certified (except for the maxi ambulance variants). The HMMWV can be equipped with a self-recovery hydraulic winch and can support payloads from 2,500 to 5,100 pounds (including crew and pintle loads), depending on the model.
Current production HMMWVs are built on the expanded capacity vehicle (ECV) chassis. The ECV variants were first introduced in 1995 as the M1113 Shelter Carrier, providing up to 5,100 pounds of payload, and the M1114 Up-armor HMMWV (UAH), to provide crew protection from small-arms fire, overhead fragmentation from artillery and mortar shells, and underbody from antipersonnel/antitank mines. Current production variants of the HMMWV family include the M1151A1 ECV Armament Carrier, M1152A1 ECV Cargo/Troop/Shelter Carrier, M1165A1 ECV Command and Control Carrier and the M1167 ECV TOW Missile Carrier vehicles. Like the M1114, the M1151 has a rooftop weapon station that can accommodate an M249 machine gun, M240/M60 machine guns, M2 machine gun, or Mk 19 grenade launcher. Unlike earlier models, these latest versions are also designed for the application of additional armor packages over their base protection levels, as the mission profile dictates.
HMMWV new production for the Army ended in February 2011; production for the other services and foreign military sales customers continued into 2013. A new M997A3 ambulance configuration, built on the ECV chassis and planned specifically for the Army National Guard to meet its homeland security and natural disaster relief missions is currently in production at Rock Island Arsenal. Because of the large numbers of HMMWV variants found throughout the Army and the continued need for their service into the foreseeable future, the Army has been conducting an extensive depot recapitalization program for older model and war-weary HMMWVs which has produced almost 50,000 recapped trucks.
The Light Tactical Trailer (LTT) is the HMMWV trailer. It has been tested and approved (materiel released) for use per the HMMWV mission profile. The LTT comes in three variants: M1101 (LTT-L), M1102 (LTT-H) and heavy chassis (LTT-HC). The Army has met the LTT requirement of 41,613 trailers, but is continuing LTT production to meet the needs of customers.
In addition to the LTT, PdD LTV manages three other trailer programs, which meet specific customer needs--the M200A1 Chassis trailer and M1061A1 flatbed trailer, which transport tactical generator sets, and the LEUT which is intended to improve mobility for combat engineer equipment. However, the HMMWV is not the prime mover for these trailer systems.
