The U.S. Army awarded AM General LLC a contract valued $733 million to produce Humvee Expanded Capacity Vehicle (ECV) variants.
This modification contract has an estimated completion date of Dec. 31, 2024.
BAE Systems has also won $50 million to produce Bradley Fighting Vehicles for the Army.
The M1097A2 is the basis for the Humvee M1113 ECV. The ECV provided the payload capacity allowing for larger and heavier communications shelters, improved armor protection level for scouts, military police, security police, and explosive ordnance disposal platforms.
Since the 1990s, the Army has built a number of ECV variants: M1113 Shelter Carrier, M1114 Up-Armored Armament Carrier, M1115 TOW Carrier (no evidence of fielding), M1116 U.S. Air Force Up-Armored Armament Carrier, M1121 TOW Carrier, M1145 U.S.A.F. FAC, M1151 Enhanced Armament Carrier (Up-Armored Capable), M1152 Enhanced Troop/Cargo/Shelter Carrier (Up-Armored Capable), M1165 Up-Armored HMMWV, M1167 Up-Armored TOW Carrier and Composite HMMWV.
A prototype XM1124 Hybrid-Electric Humvee on an M1113 Humvee chassis powered by a diesel-series hybrid featuring an all-electric drive train has been developed by RDECOM/TARDEC. The vehicle has a 9.7 km full-electric range for silent operations. It may have less emissions, save fuel in the battlefield, and can increase the survival rate in emergencies such as if one of the engines is destroyed or fails.
NXT 360 Humvee variant is available as an independent vehicle or upgrades for the M1100 Humvee series since June 2018.
