General Dynamics XM-966 HMMWV Configurations

The three primary configurations of the HMMWV vehicle system are the combat support/utility vehicle, the weapons carrier and the combat ambulance. Each of the primary configurations may be deployed in numerous variations depending on the application of many kits.

Utility Vehicle

The combat support/utility HMMWV with limited armor protection operates in range of enemy indirect fire. This configuration is used selectively in all divisions for utility, MANPADS, engineer, ground surveillance radar, electronic warfare intelligence, NBC reconnaissance, and forward deployed maintenance contact teams. In light infantry divisions the combat support utility HMMWV performs mortar transport, Tactical Operations Center (TOC), Fire Support Elements (FSE), Fire Direction Center (FDC), and Forward Air Controller (FAC) roles. The kits available to support these roles include:

  • Winch — 8000 lbs. capacity
  • Soft tops — crew cab, rear crew, cargo
  • Troop Seats — stowable for full cargo
  • Communications
  • Basic issue Items Stowage
  • Arctic
  • Deep Water Fording — up to 60 inches
  • Explosion-proof fuel tank
  • 100 Ampere Alternator
  • Mortar Transport
  • S250 Electrical Equipment Shelter

Weapons Carrier

The weapons carrier configuration consists of a weapons firing station and a lightly armored enclosure of the cargo area with stowage provisions for the selected weapon. This configuration participates with light divisions in anti armor battle with the TOW missile as the primary weapon system. The weapons carrier also provides a standard weapon mount for small caliber weapons changeability for the light infantry scout and military police application in the Rear Area Combat Operation (RACO) role. The kits which support these various combat roles include:

  • Basic and Supplemental Armor
  • TOW Component Carrier & Mounting
  • TO & E/CTA Stowage
  • Armament Mounting Kit — mounts the MK19 40mm grenade launcher, the M2 50 caliber machine gun. or the M60 7.62mm machine gun
  • Winch — 8000 lbs. capacity
  • Personal Gear Stowage
  • Deep Water Fording
  • Arctic
  • Communications
  • 100 Ampere Alternator
  • Explosion Proof Fuel Tank

Combat Ambulance

The mini and maxi combat ambulances support the airborne/air assault and infantry divisions. Although the mini and maxi ambulances carry the basic armor protection level, there is a soft top ambulance version responsive to the U.S. Marine Corps requirements. The mini ambulance maneuvers with the infantry companies and evacuates to the maxi ambulance which serves as the battalion level aid station.

Air Transportability

A critical aspect of the basic configuration is air transportability. HMMWV’s must be moved throughout a theater by C-130 aircraft and CH-47, CH-53, or UH-60A helicopters. Movement by heli­copter includes internal carrying (such as the weapons carrier entering the CH-47 shown), or external slinging. Quick reaction movement of HMMWV’s by air includes air drop and Low Altitude Parachute Extraction System (LAPES).

Future Roles

The versatile configuration of the basic HMMWV is adjustable to many battlefield systems of the future. HMMWV variants are likely to be associated with advanced weapons systems similar to the proposed Platoon Coordination Center shown on the right.
