M1165 HMMWV Expanded Capacity General Purpose Vehicle
M1165A1 HMMWV Expanded Capacity General Purpose Vehicle IAP/Armor Ready
The M1165 was a command and control/general purpose vehicle in the Expanded Capacity Vehicle HMMMWV family, based on the M1113, and was used to transport personnel. The M1165 vehicles were capable of transporting a 2-man or 4-man crew and 8 passengers. For higher payload capacity, the M1165 is equipped with a reinforced frame, crossmembers, lifting shackles, heavy-duty variable rate rear springs, shock absorbers, reinforced control arms, heavy-duty tires and rims, and a transfer case and differential with a modified gear ratio. The optional front self-recovery winch permited recovery operations of similar vehicles.
Fully loaded M1165s could climb road grades as steep as 40 percent (22 degrees) and traverse a side slope of up to 30 percent (13.5 degrees). The vehicle could ford hard bottom water crossings up to 30 inches (76 centimeters) without a deep water fording kit and 60 inches (152 centimeters) with the kit.
While the M1165 was designed to be able to integrate the Perimeter Armor of the M1114 and the various Fragmentary Armor Kits (Frag Kits) developed for the HMMWV family, it was not supplied with any armor as standard. A variant with the Integrated Armor Protection (IAP) package installed at the factory, including underbody armor, rocker armor, lower windscreen deflector armor and energy absorbing seats was developed, designated the M1165A1. These vehicles reflected the US Army's Long Term Armor Strategy of developing vehicles with adaptable armor packages. These vehicles could be fitted with a default A-Kit armor package, with the option of addition B-Kit packages offering added protection. The B-Kit for 4-door general purpose vehicle HMMWVs, known as the B3 kit, included perimeter armor, overhead armor, and rear ballistic bulkhead, bringing the vehicle up to a similar level of protection as the M1114. The B3 kit required an aluminum roof/rear panel. Frag Kits could also be installed. The added weight reduced the crew capacity to 4.
