   The Mobile Electronic Warfare Support System (MEWSS) is in service with the US Marine Corps. The US Marines ordered 12 of these vehicles in 1987, which were delivered in 1989.

   The MEWSS is based on the LAV 8x8 platform. The main missions of this mobile electronic warfare center are data collection, locating and positioning of enemy force, intercepting and jamming enemy communications. It is also capable of conducting electronic attacks against designated targets and might be operated in the forward area of operations. It is capable of operating in a variety of tactical situations.

   The LAV-MEWSS uses the same subsystems, as the US Army's mobile electronic warfare assets. It can also network with the US Army's platforms and airborne units. This vehicle has a crew of five, including commander, supervisor, two electronic system operators and driver.

   The MEWSS is armed only with a single 7.62-mm machine gun, which is used for self-defense. There are 1 000 rounds of ammunition for this MG. Vehicle also has eight smoke grenade dischargers. Also there are NBC protection and automatic fire suppression systems.

   This armored vehicle provides protection against 12.7-mm rounds at the front arc. All-round protection is against 7.62-mm rounds and artillery shell splinters.

   The LAV-MEWSS is powered by a Detroit Diesel 6V53T turbocharged diesel engine, developing 275 hp. Vehicle has 8x4 configuration, which can be switched to 8x8, depending on terrain conditions. After a short preparation vehicle is fully amphibious. On water it is propelled by two propellers, mounted at the hull rear.

   This armored vehicle can be airlifted by the C-130 Hercules and larger military transport aircraft. It can be also carried underslung by the CH-53E Super Stallion helicopter.

   Reportedly the US Marine Corps upgraded their MEWSS systems to the MEWSS PIP or Product Improvement Program standard. These carry upgraded sensor suite. The MEWSS PIP has a 9 m high extendible mast, which contains system antennas.
