US Navy & USMC Medium Tactical Vehicle Replacement (MTVR) 7 ton 6x6

Beginning in 2001, the U.S. Navy and Marine Corps Medium Tactical Vehicle Replacement (MTVR) program superseded the M-939 and M-809 5-ton trucks with a fleet of state-of-the art, commercially based, medium trucks with greater mobility, lift, and reliability. The MTVR has an increased payload of 7.1 tons cross-country and 15 tons on hard surface roads and can simultaneously tow an 11 ton load. The MTVR has a 70 percent off road and 30 percent on road mission profile and is capable of sustained speeds of 30 mph cross-country.

The USMC Medium Tactical Vehicle Replacement (MTVR) Cargo Trailer (MK105) and Water Trailer (MK149) are matched to the MTVR truck.

Commercial components include:

  • 425 horse power electronically controlled engine
  • seven speed, continuous power, automatic transmission
  • 6-wheel independent suspension
  • anti-lock brakes
  • engine retarder (“jake brake”)
  • automatic traction control
  • central tire inflation system

MTVR Series of Vehicles

The self-recovery winch is rated at 20,000 lbs. for all MTVR models.

Experience in Iraq generated the need to armor the MTVR vehicles. The MTVR Armor System (MAS) is designed specifically for the Medium Tactical Vehicle Replacement (MTVR) vehicles and was developed through the Engineering Change Proposal (ECP) process. The kit provides complete 360-degree protection as well as overhead and underbody protection for the crew compartment utilizing Mil-A-46100 High Hard Steel and Metal Composite. The MAS is intended as a permanent modification to the vehicle, and includes an upgraded front suspension and cab rebuild. The kit includes a removable personnel carrier (with ballistic glass), air conditioning system, and machine gun mount. Each MAS kit for sn MTVR variant is specific to that vehicle. MAS is also produced in reducible or non-reducible models to meet all mission requirements. The MTVR Dump Truck and MTVR Tractor MAS Variants began fielding in December 2006.

To accept the armor kit, the standard MVTR requires modifications. After such modifications, the suffix "A1" is added to the model number, e.g. MK31A1. Modified vehicles are referred to as “ready to accept armor” (RTAA).

When armored, the prefix "A" is added to the model number, e.g. AMK31 Tractor.
