The outputs of the Mark 1A were the same (gun bearing and elevation), except fuze time was added. The fuze time was needed because the ideal of directly hitting the fast moving aircraft with the projectile was impractical. With fuze time set into the shell, it was hoped that it would explode near enough to the target to destroy it with the ...

A British clockwork Time fuze for an artillery shell using the Thiel mechanism, circa 1936 British aluminium No. 25 Mk IV time fuze, using a burning gunpowder timer, circa 1914, used for star shells. Artillery Time fuzes detonate after a set period of time. Early time fuzes were igniferous (i.e. combustible) using a powder train.
The Mod 1 probably featured an improved type fuze, moving away from the simple wick lighter design. The Mod 2 featured a simplified overall design, while the Mod 3 replaced the single-piece steel body with a two-piece plastic shell.
The missile contains a 1.4-kilogram (3.1 lb) warhead with a contact fuze and a single-stage solid-rocket motor that accelerates the missile to about 650 metres per second (2,100 ft/s), about Mach 2. Engagement time to the maximum effective range is about 13 seconds.
The MK 1 is a time-fused fragmentation grenade and has 32 serrations on it. To start the fuse, the user has to pull the safety pin, then push off the cap on top of the grenade. Right before throwing, the user has to move the switch on the lever away from the grenade in order to start the fuse.
The Mk 7 Mods 3, 4, and 6 bomb dispensers have the Mk 339 Mod 1 fuze, which provides the pilot with in-flight selection of the fuze function time. The Mk 7 Mod 4 bomb dispenser differs from the Mk 7 Mod 3 by modifying the dispenser and giving interface capabilities with a wider range of military aircraft.
