Oshkosh Defense will provide the US Marines with more than 5,750 upgrade kits for the medium tactical vehicle replacement (MTVR).

Under the $44m contract, the company will deliver more than 950 weapons-mount kits for the installation of motorised marine corps transparent armour gun shields (MCTAGS), which are designed to replace the gunner protection kits on up-armoured vehicles.

Oshkosh will also supply 2,000 door-upgrade kits, which will make the doors common with those on MTVRs by using the reducible-height armour kits.

In addition, the company will deliver MTVR troop carrier upgrades, which include 800 dual-ladder kits, more than 1,000 seatbelt kits to support the carrier’s crew and more than 1,000 lift-point kits for enhanced transportability.

The contract has options that, if exercised, could bring the value of the contract up to $89m.

The contract has been awarded by the US Marine Corps Systems Command, for which the production work and deliveries are expected to be complete in September 2010.

The Oshkosh MTVR is an all-terrain, multipurpose tactical vehicle with an Oshkosh-patented TAK-4 independent suspension system and features an off-road 7.1t payload capacity.
