The Expeditionary Fighting Vehicle (EFV) (formerly known as the Advanced Amphibious Assault Vehicle AAAV) was an amphibious assault vehicle that was under development for the U.S. Marine Corps. It was intended to be launched at sea, from an amphibious assault ship beyond the horizon, able to transport a full Marine rifle squad to shore. It would maneuver cross country with an agility and mobility equal to or greater than the M1 Abrams.

The EFV was designed to replace the aging AAV-7A1 Assault Amphibious Vehicle (AAV), which entered service in 1972, and was the Marine Corps’ number one priority ground weapon system acquisition. It has three times the speed in water and about twice the armor of the AAV, as well as superior firepower. The vehicle was planned to be deployed in 2015; however, on 6 January 2011, Secretary of Defense Robert Gates announced that he recommends the EFV program be canceled. The program, which is projected to cost $15 billion, has already cost $3 billion.

The Marines have asked for the EFV to be canceled in favor of the Assault Amphibian Vehicle Service Life Extension Program, the Marine Personnel Carrier and the Amphibious Combat Vehicle.

See AAAV.com for some more background and amphibious development information.

The AAAV will join the MV-22 and LCAC as an integral component of the amphibious triad required to execute OMFTS. The AAAV will allow naval expeditionary forces to eliminate the battlefield mobility gap and, for the first time in the history of Naval warfare, maneuver ashore in a single, seamless stroke giving both the ships and landing forces sufficient sea space for maneuver, surprise, and protection. The AAAV's unique combination of offensive firepower, armor, and Nuclear, Biological, and Chemical (NBC) protection, and high-speed mobility on land and sea represent major breakthroughs in the ability of naval expeditionary forces to avoid an enemy's strengths and exploit its weaknesses. The AAAV remains the Marine Corps number one ground acquisition priority.

A7597 – TETS – AN/USM-657v3

TETS is a portable, automated test unit that is controlled by a Common Hardware Laptop computer. It is a modular design configuration using mature and proven Non-developmental Item components and modules to accommodate 3 configurations: Radio Frequency (RF), Electro-Optical (EO), and a combined RF/EO. The RF configuration will consist of the basic configuration plus additional test capability to screen RF Modules and Circuit Cards. The EO configuration will consist of the basic configuration plus additional test capability to screen EO Modules and Circuit Assemblies. The combined configuration will have both RF and EO testing capabilities. TETS will also have the capability of discrete component diagnostics. Primary power input is 28VDC, provided via the standard NATO slave receptacle on a HMMWV and other vehicles. Secondary input power is 108-220 VAC, 40-400 Hz.

TETS tested the following equipment (utilizing application program set (APS)):
MRC-142 (AN/PSM-107)
TRC-170 (AN/PSM-105)
TPS-63 (AN/PSM-100)
TPS-59 (AN/PSM-106)
TPQ-46A (AN/PSM-109)
TOW (AN/PSM-111)
TAS-4C (AN/PSM-108)
