Description: Point Detonating Fuze Mk 26 Mod 0 consists essentially of the following parts: The nose or body unit (into which is fitted the rear disc or air channel) and the closing unit, which contains the detonator.

The Point Detonating Fuzes Mk 26 Mods 1 and 2 consist essentially of two pieces: (1) the nose or main body and (2) the magazine, which contains the same detonator used in the Point Detonating Fuze Mk 26 Mod 0 and an additional booster of tetryl below the lead azide detonator.

Operation: The fuze has no safety features in its design, but it will withstand a 40-foot drop onto armor plate without detonation. In the Mk 26 Mod 0, the nose cap is crushed on impact, causing the air in the air channel to be compressed and forced through the hole in the concave disc. This action generates sufficient pressure and heat to set off the very sensitive lead azide detonator beneath the disc. In the Mod 1 and Mod 2, there is nor air channel of disc, and the fuze is fired entirely by the shock of im-pact. The very sensitive detonator will be set off by the shock of impact; and it, in turn, will set off the magazine of tetryl beneath it.

Remarks: These fuzes will not detonate on water impact, but they will detonate on 1/8-inch mild-steel. The Mods 1 and 2 are more sensitive than the Mod 0 to both impact and heat. No more Point Detonating Fuzes Mk 26 Mod 2 are being made.
