Use: This is a distress signal from grounded planes.

Projection: The Pyrotechnic Pistol AN-M8 or Hand Projector M9 is used for firing the flare.

Description: The cylindrical, aluminum outer case has an extraction groove at the end containing the primer. A press-fit identification top is cemented to the end opposite the primer and has the ambossed letters "R.P." for night identifiaction. This cartridge is classified by the Army as the rimless type.

Operation: The firing pin of the pistol sets off the primer; igniting the propelling char-ge. The propelling charge ignites the delay fuse and propels the inner case outward. The delay fuse burns for 2.5 seconds and ignites the candle and expels the candle and para-chute from the inner case.

Remarks: The Army has other parachute signals which are similar to the M11. These are obsolete or limited standard items:
