Marines: Last Chance For The EFV

Archives

June 9,2008: The U.S. Marine Corps has a procurement disaster on their hands. It's all about their new EFV (Expeditionary Fighting Vehicle). Congress is refusing to provide money for mass production until reliability and protection (against roadside bombs) issues are taken care of. So far, prototype EFVs have had one failure, on average, for every 4.5 hours of operations. The marines insist they have fixed the reliability and protection issues, and Congress has provided money to build seven of the modified EFVs to confirm that. The seven new EFVs will be used to test reliability and roadside bomb protection. If the tests are successful, Congress will allow development to continue.

Two years ago, it was decided that, instead of buying 1,013 EFVs, the order would be cut 44 percent, to 565 vehicles. High development expenses have resulted in per vehicle cost of over $12 million. Costs have continued to climb, and each EVF will not only cost over $22 million, but the vehicles won't be ready for service until 2015. The EFVs were originally supposed to start entering service in 2008.

The marines ordered the first 15 production models of its EFV in late 2005. Tests with these vehicles did not go well. While the high-speed water-jet propulsion system feature (the cause of most of the problems) is still there, it may have to go if the marines are ever to get their new armored vehicle.

The EFV is an amphibious armored vehicle, was previously called the AAAV (Advanced Amphibious Assault Vehicle). Weighing nearly 36 tons, the EFV is 10.5 feet tall, 12 feet wide and just under 30 feet long. It's armed with a 30mm automatic cannon (MK34 Bushmaster) and a 7.62 mm co-axial machine gun. The EFV also has better armor protection and electronics than the AAV7 is replaces.

The EFV has been in development for over a decade, and has been delayed largely because of a complex water-jet propulsion system which allows it to travel at 60 kilometers an hour while in the water. This capability was specified to reduce the danger (from enemy fire) when the EFVs were moving from their transports to shore, a distance of 30-50 kilometers. The additional gear required for the water jet system made the vehicle less robust and reliable, and fixing those problems has taken a lot of time. Otherwise, the EFV is basically a truly amphibious Infantry Fighting Vehicle (IFV), similar to the army's smaller M-2 Bradley. The EFV has a crew of three, and carries 18 passengers.

The current force of 1,057 AAV7s entered service three decades ago and are falling apart. Moreover, some two thirds of the AAV7s saw service in Iraq, where they got as much use in two months as they normally did in two years of peacetime operations. In response to this, most of the AAV7s are being refurbished, so they can still be used until the end of the decade, when enough EFVs will be entering service to replace the older vehicles.

The EFV is about 25 percent heavier than the AAV7, and somewhat larger. It now costs nearly ten times as much as the $2.5 million AAV7 (taking inflation into account). The marines apparently feel they can get by with half as many amphibious armored vehicles because future wars are likely to be more dependent on delivering troops by air, or moving them around in armored hummers.
