"The M412 kinetic penetrator was a military-grade kinetic penetrator dart developed and used by the Royal Manticoran Marine Corps. It was a 650 kilogram dart-shapped projectile fitted with a short-lived but powerful impeller drive, a capacitor ring for onboard power, and a guidance package. The Navy's Mark 87 \"Damocles\" Kinetic Strike Package could be equipped with up to six of these projectiles. (HH14)"@en . "M412 kinetic penetrator"@en . .
