Mk 7 and Mods Bomb Dispenser
The cargo section of the Mk 7 bomb dispenser is
the main structure of the weapon and contains the
bombs/bomblets. A nose fairing is attached to the
forward end of the cargo section for aerodynamics and
fuze installation. It has an observation window for
viewing the safe/arm indicator on the installed fuze.
The dispenser has two linear-shaped charges secured
longitudinally inside the walls. When initiated, these
shaped charges cut the dispenser in half, from front to
rear, and the bombs/bomblets spread in free-fall
trajectories.
