| Description: |
|---|
| The cartridge has a cylindrical case designed for electrical firing from an aircraft multi-barrel ejector. Successive round fire control is by an intervalometer to time flashes with camera exposure requirements. The case contains an inner aluminum cylinder housing the photoflash charge and a delay fuse. The black powder propelling charge is contained at the base of the photoflash cartridge case. A gas check wad separates these components. The delay fuse is assembled with a detonator and extends into the center of the photoflash charge. An M59 electric primer is fitted into the base of the cartridge case. The cartridge is stored and shipped with a metal shunting clip over the base to protect the primer from accidental firing. Three time delay options are available: 2, 4, or 6 seconds. |

| Functioning: |
|---|
| The primer is fired by an electric current timed by the intervalometer in the aircraft. The primer ignites the propelling charge. The propelling charge ejects the inner photoflash charge case out of the cartridge case and ignites the delay fuse. At the end of the delay time, the delay fuse ignites the detonator and the detonator ignites the photoflash charge. The resultant explosion produces a flash brilliant enough for photography of the terrain. |
