The after portion of the body is internally threaded to receive a spigot, by which the shell is attached to the shell ring of the rocket motor. In the spigot are carried a gun-powder thermal initiator and a base fuze, beneath which is located a C.E. booster pellet. The shell is painted dark green over-all, with a 1/2-in- white and a 1/2-in. red band near the nose.

| Use: |
|---|
| This is an aircraft rocket weapon, the designed primarily for u«e against submarines and merchant shipping, although more recently wide use of the rocket has been made against land targets of an unarmored or lightly armored nature. The round consists of a 3-in. aircraft rocket motor and one of the five following heads: Shell. H.E., 60-lb., F., No, 1 Mk I; Shell, H.E., 60-lb., S.A.P., No. 1 Mk J (with delay); Shell, H.E. 60-lb., S.A.P., No. 2 Mk 1 (without delay ); Shot, 25-lb-, S.A.F., Mk I; Shot, 25-lb., A.P., Mk I; and Shot, 25-lb., A.P., Mk II. In addition, two concrete practice heads are also used, one: weighing 25 lb. the other 60 lb. |
| Functioning: |
|---|
| The Head No. 1 Mk I employs the Fuze No. 865 Mk 1 (with delay) and the No. 2 Mk I uses the Fuze No. K7H Mk I (without delay). This is the only difference in the two shells. Shot, 25-lb., S.A.P., Mk Ithis is a solid steel shot. The nose portion of the shot is ogival, while the after portion terminates in a threaded spigot of reduced diameter, which screws into the shell ring of the rocket motor. The shot is painted black over-all, except for the nose end, which is painted white for a distance of one inch. Shot, 25-lb., A.P., Mk Iexternally this shot appears identical to the S.A.P. shot. The nose portion is ogival, and the after body consists of a threaded spigot of reduced diameter, which screws into the shell ring of the motor. This spigot, in the case of the A.P. shot, is a separate component screwing into the internally threaded base portion of the shot. The spigot is held in place by a locking pin or a set-screw, which pierces the spigot and engages the shell body. The shot is painted black over-all, but carries a 1/2-m. white band in addition to the 1-in. white tip on the nose. |
