recoil of the gun assembly; analysis indicates the recoil will be a max- 

 imum of 15 feet (4.6 m) . The firing assembly is a mechanical system that 

 triggers the embedment sequence (Figure 4). A solid steel rod, which 

 can be stowed with the probe above the end of the fluke, serves as the 

 touchdown probe. When the rod is pulled down, spring- loaded pins lock 

 the rod to the firing ring. Upon probe contact with the seafloor, the 

 firing ring is moved upward, engaging the trigger arm of the S/A and 

 releasing the firing pin. The S/A has a hydrostatic lock that prevents 

 firing above a water depth of 10 to 12 feet (3 to 4m). The cartridge 

 assembly consists of an aluminum or steel cartridge base that is epoxied 

 to a phenolic cartridge case to form the propellant container. The ord- 

 nance consists of 5 -inch (1-27 mm)/38 caliber gun propellant (M6) and 

 a shortened M58 primer (Figure 5).
