Abstract:

The U.S. Marine Corps USMC Floating Smoke Pot FSP MK 7 MOD 0 Program was established to redesign the previously fielded M4A2 Hexachloroethane HC FSP. Although the HC pots were extremely effective as an obscurant, there were safety concerns from manufacturing and operational perspectives. Red phosphorous RP has been widely used in screening applications and was chosen as a replacement for the smoke payload. The smoke payload approximately 8 kg contained within the FSP MK 7 KM03 pot is a specific formulation developed by Diehl BGT Defence Uberlingen, Germany. One compound of particular concern with RP is the potential generation of phosphine gas during long-term storage. The phosphine concentration inside the storage hobbock was evaluated following 3 years of storage under ambient conditions. The smoke pots were then functioned to determine reliability following long-term storage.
