Product Improvement Program 1-84-09-7133 25 mm Metal PA 125 Container.

摘要

The initiation of the PA125 metal container program was to alleviate the deficiencies of the current plastic 25 mm M621 container in the areas of seal capability, structural integrity and flammability problems. The PAl 25 was designed to meet the current military packaging requirements including the ability to maintain a 3 psi seal after rough handling throughout the temperature extremes of -650 to 1600 F. In addition, the container was designed to interface with the stowage system of the Bradley fighting vehicle system. The design effort for the PA125 consisted of the redesigning of the internal system and the metal container with a removable cover. Because of the vehicle interface requirement, the internal support has to house two 15-round belts of ammunition in a very tight configuration. Extensive engineering evaluation was conducted throughout the program to insure the most efficient nesting configuration for conserving space while still providing excellent protection for each cartridge during rough handling. The container demonstrated excellent performance during the qualification test program managed by TECOM and evaluated by AMSAA. The program objectives have been accomplished successfully and the container is well received by the Army. Implementation of the PA125 has been initiated for the the M91 0, M791 and M793 buys starting in FY93 to phase into the 25 mm ammunition while the M621 container will be gradually phased out of the system.
