Use: This Photoflash Bomb AN-M46 was developed so that planes engaged in night photography reconnaissance need not be limited to low altitudes.

Description: In appearance it resambles a conventional light-case bomb. Uses a Fuze M111A2 in the nose, but it is issued unfuzed. It also has two suspension bands for rack and shackle suspension.

Operation: When the bomb is dropped, the arming wire is pulled, starting the mecha-nical time fuze. When the time set on the fuze has elapsed, the flashlight powder is igni-ted by the fuze booster.

Remarks: Because of the brilliance of the flash, it is detrimental to the vision to watch the explosion of photoflash bombs. Extreme care should be exercised in handling these bombs, because the charge is very sensitive to friction, shock, and temperature. These bombs should not be jettisoned over friendly territory, as they may function on impact.
