On January 6, 2011, after spending approximately 3 billion in developmental funding, the Marine Corps cancelled the Expeditionary Fighting Vehicle EFV program due to poor reliability demonstrated during operational testing and excessive cost growth. Because the EFV was intended to replace the 40-year-old Amphibious Assault Vehicle AAV, the Pentagon pledged to move quickly to develop a more affordable and sustainable vehicle to replace the EFV. The Amphibious Combat Vehicle ACV is intended to replace the AAV, incorporating some EFV capabilities but in a more practical and cost-efficient manner. In concert with the ACV, the Marines were developing the Marine Personnel Carrier MPC to serve as a survivable and mobile platform to transport Marines when ashore. The MPC was not intended to be amphibious like an AAV, EFV, or the ACV but instead would be required to have a swim capability for inland waterways such as rivers, lakes, and other water obstacles such as shore-to-shore operations in the littorals. Both vehicles are intended to play central roles in future Marine amphibious operations. On June 14, 2013, Marine leadership put the MPC program on ice due to budgetary pressures but suggested the program might be resurrected some 10 years down the road when budgetary resources might be more favorable. In what was described as a drastic shift, the Marines decided to resurrect the MPC in March 2014. The Marines designated the MPC as ACV Increment 1.1 and planned to acquire about 200 vehicles. The Marines also plan to develop ACV Increment 1.2, a tracked, fully amphibious version, and to acquire about 470 vehicles and fund an ongoing high water speed study. Although ACV Increment 1.1 is to have a swim capability, another mode of transport ship or aircraft would be required to get the vehicles from ship to shore. On November 5, 2014, it was reported the Marines released a draft Request for Proposal RFP for ACV Increment 1.1.
