 General Amos received an analysis of ACV alternatives in November 2013, so it was unlikely he could make a decision on whether to develop or buy a vehicle in the Marine's FY 2015 budget request, due February 2014.Despite the Marine's ship-to-shore amphibious landing role and the ACV being declared the service's number-one priority, there are factors that put its future in doubt.Options for vehicle capabilities were to create a high-speed platform that meets desired goals which may come out to be too expensive like the previous EFV program, create a low-speed platform with reduced performance for affordability which may not be enough of an improvement over the AAV it is replacing, or delay the effort for more research and development time to refine requirements and wait for budget problems to pass.
