REDUCED LAT and FAT TESTING PLAN

A reduced test program has been developed to reduce the cost of LAT and FAT for the M772 & M776 fuzes, and to more accurately reflect the maturity of the MTSQ fuze design. Input from JUNGHANS MicroTech and CCDC-AC Quality Assurance were used to create the reduced testing and sampling plan.

The proposed LAT for the M772 and M776 fuzes are listed below in Tables 1 and 2, respectively.
