This triad of capabilities EFV – MPC – JLTV comprises the USMC ground mobility portfolio and the means by which expeditionary, scalable, and networked armored protected seats will be provided to the Marine Air-Ground Task Force in the future.

The two-year investment period allowed for the maturation of Government Furnished Equipment and armoring technologies the Marine Corps plans to integrate onto the vehicles once produced.

In addition, an MPC Technology Demonstrator vehicle effort will be initiated to inform CDD development on achievable capabilities and integration risks at the Nevada Automotive Test Center.

Winners each received $3.5 million contracts for a demonstration and study vehicle for water performance evaluation, survivability testing, and an analysis of human factors and stowage capacity starting in fall 2012.

The Havoc demonstrated its resistance to water penetration and ability to negotiate all surf and wave conditions while accommodating a full complement of Marine Corps battle gear for the crew.

The General Dynamics MPC entry is based on their LAV III APC with a Double V-hull, making it the first vehicle with the hull design to have swim capabilities.

The human factors evaluation demonstrated the spacious interior by accommodating the specified number of combat-equipped Marines and enabling rapid tactical and emergency egress through a quick-release hatch.

The vehicle completed all threshold and objective protection system testing, with instrumentation indicating that no disabling injuries would have resulted to any of the three crew members and nine dismounted Marines.

Lockheed also delivered a report demonstrating the high degree of commonality between the Havoc and other Marine Corps vehicles, aimed at reducing cost, training requirements, and logistics needs.

[8] In June 2013, days after General Dynamics completed water performance swim and human factors testing, the Marine Corps officially put the MPC program on hold.

Marine officials promised to maintain contact with interested vehicle manufacturers so that if the decision was made to restart the MPC program, it could be done in an expeditious and cost-efficient manner.

Given technological advancements as well as emerging threat weapons systems and the constantly changing geo-strategic environment, the MPC developmental requirements may not have been valid or relevant over the next five to ten years.

When budgets tightened, the ACV was taken as the priority and funding was removed from the MPC, with the service figuring they could buy an off-the-shelf wheeled troop transport later when money was available.

Technical challenges to the proposed ACV continued to mount as funds kept getting constrained, so the decision was made that wheeled APC advancements were significant enough to address needs quicker.

Marines still want a high-speed fully amphibious vehicle to move troops from the ocean to a beach with enough armor, mobility, and firepower to fight while on land, so a phased approach was decided for the ACV.

There was some suggestion of incorporating the MPC into ACV Phase 1, and combining it with a high-speed watercraft that can bring it to the landing area, or close enough that it can use its own limited amphibious capabilities.
