Number: RS22947 Title: The Marines' Expeditionary Fighting Vehicle (EFV): Background and Issues for Congress Authors: Andrew Feickert, Foreign Affairs, Defense, and Trade Division Abstract: The Expeditionary Fighting Vehicle (EFV) is an armored amphibious vehicle program that originated two decades ago to replace the 1970s-era Amphibious Assault Vehicle (AAV). The EFV has experienced a variety of developmental difficulties, resulting in significant program delays and cost growth.
