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 (FoV). The versatile HMMWV is the Army’s universal vehicle providing a common, light tactical wheeled capability. The HMMWV is a key part of the light tactical wheeled fleet, comprised of HMMWVs, Joint Light Tactical Vehicles (JLTVs) and Infantry Squad Vehicles (ISVs), and continues to provide a critical capability across combat, combat support, and combat service support missions of the United States military.

HMMWV with trailer

Current production HMMWVs are built on the Expanded Capacity Vehicle (ECV) chassis. The ECV variants were first introduced in 1995. 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. M1151A1 variants have 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. The Cargo/Troop/Shelter Carrier provides up to 5,100 pounds of payload. The new M997A3 ambulance configuration is built on the ECV chassis and carries up to four litter patients. The M997A3 Ambulance is currently in production at the U.S. Army's Rock Island Arsenal, IL.

Mutiple HMMWV Variants

A total of more than 250,000 HMMWVs have been built over more than 30 years of production. HMMWVs remain in service world-wide with the Army, other United States armed services, and Foreign Military Sales (FMS) customers. The Army's enduring requirement for Light Tactical Vehicles is currently 105,563. Of these, 56,464 are HMMWVs. Unit authorizations are expected to decrease over the coming years as Joint Light Tactical Vehicles (JLTVs) are fielded.

The HMMWV FoV is comprised of the Up-Armored HMMWV (UAH) fleet, the Non-Armored HMMWV (NAH) fleet, and M997A3 Ambulance. PdD LTV is also responsible for the following trailer systems: Light Tactical Trailer (LTT), M200A1 2.5-ton Flatbed Trailer, M1061A1 5-ton Flatbed Trailer, and the Light Engineer Utility Trailer (LEUT).

The HMMWV FoV consists of multiple configurations built on a common chassis to support weapon systems, command-and-control systems, and ambulatory systems. The HMMWV also provides 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 ambulance variant). 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.

The Army met its desired acquisition objective for the HMMWV in February 2011, however as the older model unarmored HMMWVs meet their economic useful life, and are divested, the Army continues to produce new HMMWVs and recapitalize older models at the Army depots to ensure the fleet remains modernized and incorporates critical safety technologies such as ABS/ESC. This approach ensures alignment with the Army’s modernization strategy and balances capabilities across the HMMWV, JLTV and ISV fleets.

PD LTV also manages the Army’s light tactical trailer fleets. This includes the M1101 and M1102 light tactical trailers (LTT), which have trailer boxes to haul various payloads, and the Light Tactical Trailer Heavy Chassis (LTT-HC) which is a frame-only trailer used to haul payloads such as generators. The Army has fielded 41,613 of these trailers, but is continuing production to meet the needs of customers. In addition to the LTT and LTT-HC, PdD LTV manages three other trailer programs to meet specific customer needs. These include the M200A1 Chassis trailer, M1061A1 flatbed trailer, and the Light Engineer Utility Trailer (LEUT). The M200A1 and the M1061A1 trailers transport tactical generator sets. The LEUT is intended to improve mobility for combat engineer equipment.
