explosive, NOL has recently developed what is believed to be the most sicnificant electric time fuze in the country. Experimental models of the hich accurate ‘RUE'LMAN time circuit have been furnished the Sindia Corporation. Buéer has co= . operated with BuOrd on the fuzing for the Mark 6 and TX-11 and developed the . MC=215. ' FULING SYSTEMS - Mechanical - BuCrd and its principal fuzing laboratory, NOL, have considerable ex~ @rerieree in this field. Capabdilities exist for developing fuzes actuated by clockwork, mechanical extrusion, inertia deeny, soluble plur, capillarity, resist condensor, magnetic decoy, and thermo-conduction. It is of special imnortance that BuOrd works on complete systems, including detection, acquisition, desienati fire control, and computing equipment, weapcns, ammunition, handling fuzing, and recording, and evaluation devices. FUZIG SYSTES - Inertial Inertial or integrating fuzes are 2 possibility for which compstence ¢,, should exist at NOL, NRL, and other Navzl Laboratories. FUZING SYSTEUS = Impact BuOrd has vast experience in this field, one manifestation being the Mark & fuzee NOTS has done some work in connection with shape charged fuzes for rockets, but most fuzing has been done by NOL which pioncered in the fast as well sates as the slower impact fuzes, including the cryst2l type which requires ne battery, FUZING SYSTEMS ~ Hydrostatic Hydrostatic fuzcs are a standard problem of NOL and BuOrd. These activities have also developed actuating devices for mines which utilize a wide variety of physical phcnomena. POWER SUPPLY - Batterics 4 BuCrd and its stations are experienced in battery development, particu larly for mines and other underwater ordnance, VP fuzes and guided missiles. Two representative developments are the silver cel] battery for METSOR and the NOL Thermo-cell for fuzes which is activites by a pyrotechnic. with the ARC in battery work.
