Description: The projectile casing is of forged steel. The nose screws onto the main body at a point just behind the bourrelet. The main body is joined to the base with a press-fit held by four screw shear pins. The propellant base housing which screws onto the shell base is similar in construction and operation to that of the H.E. shell. The smoke mixture is held in a brass can inside the main body and has attached to it by a short cord a steel retarder cup to slow its descent. |
|
Operation: When the fuze gaine fires, it ruptures the thin plate in the base of the gaine, ignited the smoke mixture, and expels the smoke candle from the shell casing. |
