Mk 8

The Mk 8 was an early earth-penetrating bomb or bunker buster, intended to dig in deep and then detonate. It was the first tactical bomb ever deployed by the United States. Developed by the Navy, the Mk8 was a simple design based on the Mk 1 Little Boy bomb and could be carried externally or internally by aircraft. It was for use against hardened or underground targets, such as bunkers, command centers and submarine pens.
