Description
The 2.5-inch sub-ealiber rocket, consisting of the 1.25-inch Motor Mk 1 and 2.5-inch Head Mk 1, is a miniature of the regular rocket and is used in practice. The motor contains a single tubular powder grain, an igniter, and lead wires. The tail fins, supported by a shroud, are offset five degrees to impart some rotation to the round, to improve underwater travel. The Head Mk 1 has a cavity for a shotgun shell; the Head Mod 2 Mk 1 is solid.
