HMMWV Expanded Capacity Vehicle

The first of the Expanded Capability Vehicle HMMWVs, the M1113, was introduced in 1994. The ECV HMMWVs also went into series production in 1995. The payload of these vehicle was 5,100 lb, including the crew. The introduction of the M1113 was followed shortly thereafter by the M1114, a so-called Up-Armored HMMWV, with enhanced ballistic protection. Previous prototypes had been constructed using the A1 series chassis, resulting in the XM1109. This vehicle's performance suffered due to the additional weight. The ECV chassis of the M1113 was combined with the armor kit of the XM1109 to form the M1114. These vehicles went on to serve most notably in Bosnia. The M1113 supplemented the M1097A2 with hopes of eventually supplanting the latter vehicle.

In 2000, 2 additional variants were added to the ECV family. The US Air Force acquired a variant of the M1114 for its Security Forces, designated the M1116. This vehicle featured a visible configuration more similar to the A1-based XM1109. It would later go on to be utilized by the US Navy for similar security duties. A variant for Tactical Air Control Parties, the M1145, was also acquired to replace standard HMMWVs in this role. The added payload of the ECV chassis allowed the new vehicle to better carry the specialized equipment required, as well as allowing for the installation of the enhanced ballastic protection of the M1114. A TOW missile carrier variant of the M1114, designated the M1115 was also developed, but it was unclear how many vehicles, if any, were fielded.

Providing armored vehicles to the Armed Forces deployed in contingency operations was issue of great concern following issues immediately experienced after the invasion of Iraq in 2003. While there were problems in rapidly supplying Up-Armored HMMWVs and add-on armor for Army and Marine Corps tactical wheeled vehicles when the insurgency began in Iraq in the fall of 2003, the Department of Defense took aggressive steps to satisfy the evolving force protection requirements of US Central Command (CENTCOM).

The Congress also responded quickly to the force protection requirements of CENTCOM. From FY03 to FY05, the Congress added $1.9 billion to the President's requests to increase Up-Armored HMMWV production and almost $1.6 billion to increase the production of add-on armor protection for tactical wheeled vehicles for the Army and Marine Corps. In the Emergency Supplemental Appropriations Act for Defense, the Global War on Terror, and Tsunami Relief Act, 2005 (H.R. 1268, as adopted by the House of Representatives on 5 May 2005 and the Senate on 10 May 2005), the Congress added $150.0 million for Up-Armored HMMWVs and $610.9 million for add-on armor for tactical wheeled vehicles. With this funding, the CENTCOM Up-Armor HMMWVs and add-on armor requirements at the time were to be fully addressed.

AM General, LLC, of South Bend, Indiana, was awarded on 1 March 2005, a $59,963,442 modification to a firm fixed price contract by the US Army Tank-Automotive and Armaments Command for 814 M1152 High Mobility Multipurpose Wheeled Vehicles and 31 M1151 High Mobility Multipurpose Wheeled Vehicles. Work would be performed at South Bend, Indiana, and was expected to be completed by 31 March 2006. This was a sole source contract initiated on 17 July 2000.

AM General, LLC, of South Bend, Indiana, was awarded on 23 June 2005, a $19,617,847 modification to a firm-fixed-price contract by US Army Tank-Automotive and Armaments Command for purchase and installation of armor kits for the M1151 High Mobility Multi-Purpose Wheeled Vehicles. Work would be performed in South Bend, Indiana, and was expected to be completed by 31 January 2006. This was a sole source contract initiated on 17 July 17, 2000.

The FY06 and FY07 budgets procured 5,307 HMMWV's of which 720 were the M1114 Up-Armored vehicle. The balance of the funding procured 180 M1151's with armor and 4,407 Armor Ready M1152's. The standard M1151 armament carrier had basic armor, while the M1152 cargo/troop was unarmored. Both vehicles were designed to readily accept armor packages as part of the US Army's Long Term Armor Strategy. These vehicles represented an expansion of the basic and unarmored components of the Expanded Capability Vehicle series. An unarmored general purpose/command vehicle variant, the M1165 was also developed. This was followed by the development of an up-armored TOW/ITAS missile carrier, the M1167, rounding out the standard models in the ECV family by 2009.
