BAE Systems said last week it has received four delivery orders totaling $226 million from the Marine Corps for engineering changes and spare parts to support Mine Resistant Ambush Protected (MRAP) vehicles.

“These changes provide improved mobility and survivability capabilities that take the performance of the RG33 platform to a whole new level,” Matt Riddle, vice president for Wheeled Vehicle Programs at BAE, said in a statement. “These enhancements significantly extend the mission envelope and improve the war fighting capabilities of the vehicle,” he added.

BAE manufactures three of the five MRAP variants: the Caiman, the RG31 and the RG33.

The RG33 is manufactured in several configurations including the Category I 4×4, Category II 6×6, the Heavy Armored Ground Ambulance (HAGA) and the Special Operations Command (SOCOM) vehicle.

The first order is for engineering changes to 51 HAGA and 393 Category II 6×6 vehicles. This contract was awarded in March 2008 and is worth $162 million.
