回答: Yes, it is a bigger gun than the current Navy guns, but with 由 008 于 2008-02-04, 17:13:04:

in Arizona, was created by a 50 meter-cross nickel-iron meteor at the speed of 20km/s. The crater is 1200m in diameter, and some 170 m deep. The impact was about 2.5 mega-tone, 150 time bigger then the Hiroshima atomic bomb. That is caused by kinetic energy alone. Rethink about your statement of kinetic energy penetrator. Currently the most lethal anti-tank weapon is nothing but a deplete uranium core. If a tank got hit by this sucker, everyone in the tank will died.
