Here's one:

LOSAT (lit; Line Of Sight Anti-Tank] was the first hypervelocity, hyperkinetic energy anti-tank system to be developed. It was prototyped by LTV after studies of earlier hypervelocity rockets showed promise. The guidance trials showed that the missiles guidance system, which relied on receiving trajectory-correction signals through the missiles exhaust plume, was not up to the task.

LOSAT.
That's ours.
Russia is way behind in that arena.
Unless we get stupid and sell it to people.

October 21, 2003: The U.S. Army has not given up on using very high speed (5,000 feet per second, twice the speed of a rifle bullet) missiles to take out tanks. The Compact Kinetic Energy Missile (CKEM), which will weigh about 90 pounds and be five feet long, is under development. CKEM is this about half the size and weight of the older, and now cancelled, Line-Of-Sight Anti-Tank (LOSAT) missile. CKEM will use the same guidance system and other LOSAT technology. The only problem is that the smaller warhead may have trouble doing what LOSAT promised to do; waste any tank in the world. A new design for the warhead (which in LOSAT was just plain old rod of hard metal--as is used in tank gun shells) might do it. Time will tell, and tests for CKEM are at least a year away.

LOSAT is still around and is being improved...
