The Assault Amphibian Vehicle Reliability, Availability, Maintainability/Rebuild to Standard (AAV RAM/RS) Program was approved in 1997. It encompassed all AAV systems and components to return the AAV to the original vehicle's performance specifications and ensure acceptable readiness until the EFV should become operational. The program replaced both the AAV engine and suspension with US Army M2 Bradley Fighting Vehicle (BFV) components modified for the AAV. Ground clearance returned to and the horsepower to ton ratio increased from 13 to 1 to its original 17 to 1. The introduction of the BFV components and the rebuild to standard effort was expected to reduce maintenance costs for the expected remaining life of the AAV through the year 2013.
