Description
The illuminating projectile is a thin case with a very small expelling charge just behind the fuze and an interior assembly of a star or candle with a parachute and a very lightly held base plug. Explosion of the expelling charge forces out the base and the interior assembly.
The Mod 2 projectile, used in the 5"/25 gun, is identical to the Mod 1, except for modification of the rotating band. When these projectiles are used in the 5"/51 bag gun, the Primer Mk 15 Mod 1 is used, and the Nose Fuzes Mk 50 and Mk 63 may be employed. Use of the Nose Fuzes Mk 50 and Mk 63 is not authorized with rounds used in the 5"/25 and 5"/51 case guns. The Illuminating Contents Mk 3 are used with projectiles Mods 1 through 4: projectiles Mods 5 and 6 are assembled with Illuminating Contents Mk 4 Mod 5 when used in the 5"/51 bag gun. Illuminating Contents Mk 3 when used in the 51"/51 case gun.
