Oshkosh Defense Keeps
MTVR Production Rolling
The Medium Tactical Vehicle
Replacement (MTVR) is the standard medium truck of the Marine
Corps and Navy Seabees. It
replaced the M809/M939-series’ 5-
ton trucks and gave the services a
15-ton on-road and 7-ton off-road
capability. The MTVR is built in 13
different versions, including various cargo, dump, tractor and
wrecker vehicles. The MTVR also
is a resupply component of the
High-Mobility Artillery Rocket
Wisconsin-based Oshkosh Defense has received orders for
11,320 MTVRs: 9,440 for the
Marine Corps and 1,880 for the
Seabees. As of June, 11,009 had
been delivered: 9,189 for the
Marine Corps and 1,820 for the
Seabees. Oshkosh also has delivered more than 350 6x6 MTVR
tractors and tanker trailers to the
U.K. Ministry of Defence for its
Wheeled Tanker program. The
total value of the U.S. MTVR program exceeds $1 billion.
The Medium Tactical Vehicle Replacement’s TAK- 4 independent suspension
allows it to travel at high speeds across difficult terrain while maintaining ride
quality for vehicle occupants.
Oshkosh was awarded a contract
for the MTVR in 1998 and began
full-rate production in 2000.
Deliveries under a $67 million
September order for 267 MTVRs
are ongoing, and a $7.9 million
order of 32 MTVRs was awarded

The MTVR is the medium fleet workhorse for the Marine Corps. In
the late ’90s, the Marine Corps was seeking to replace its medium
tactical vehicle fleet with a much more robust off-road severe-terrain capability. They wanted a vehicle that could handle a mission profile that was
70 percent off-road and only 30 percent on-road. Additionally, the Marine
Corps wanted a 7-ton off-road cargo capacity.
Previous tactical wheeled vehicles had to go slow across difficult terrain
and were limited in their off-road capabilities just by the ride quality at speeds
across country. The MTVR features the TAK- 4 independent suspension, the
key to the MTVR’s off-road mobility. The 16 inches of independent wheel
travel allows high speeds across very challenging and difficult terrain while
still maintaining an excellent ride quality for the occupants of the vehicle.
The MTVR also provides automatic traction control and a central tire inflation system, and the Command Zone electronic suite allows control and diagnostics of the MTVR. It allows the crew to more easily repair and troubleshoot vehicles and allows real-time observation of performance data.
During Operation Iraqi Freedom, Oshkosh designed, produced and
fielded a number of protection upgrades for the MTVR, in essence adding
[Mine Resistant Ambush Protected] MRAP-level protection to the platform for operation in those theaters.
We’ve fully matured and provided for the MTVR our ProPulse diesel-electric hybrid kit technology, an onboard vehicle power system that provides 120 kilowatts of export power. That essentially turns a medium tactical vehicle into a very capable generator. It eliminates the need to tow generators and reduces the footprint that generators take up in addition
to the vehicles as they are being spotted in amphibious shipping.
