The LOSAT is a 6 & 1/2 inch dia., 10 ft. long, 150 lb laser beam riding missile with impact energy of 60 mega joules. [Compare that with the 12 MJ muzzle energy of a 120mm/44 cal NATO gun.] A test program is providing a company of them to the 18th Corps. Each launcher has four missiles packed on a Hummer chassis.
There have been a number of LOSAT tests. One, on a M-48 target tank, pushed the hull back 10 feet during impact, ignited a _stripped_ tank hull and exited the engine grill substantially intact. Another, on an empty-of- ammunition T-72, decapitated the turret. These test films are available, though tightly held.
