Development, Test and Evaluation of the Rocket Launcher Safety and Arming Device (MLU-53/B)

Abstract : The Rocket Launcher Safety and Arming Device (S+A), MLU-53/B, was developed for use in the ZAP weapon system. The S+A program fell into four production/test and evaluation phases. Testing in each of these phases revealed weaknesses which were corrected in the next production phase. Because of tight schedules, weaknesses found in Phase III hardware, could not all be corrected in Phase IV production. These changes were approximated by the U. S. Naval Ordnance Laboratory, White Oak, on the Phase IV hardware. The limited Phase IV (OPEVAL) testing done indicated that the MLU-53/B S+A device was a workable item which represented a quantum step toward a safer air launched weapon system.
