Abstract : Initial tests are reported of the XB-44A fuze to determine its functioning ability and delay after steel plate impacts. Dual primers, detonated upon impact by firing pins, initiate a pyrotechnic delay train which provides about a 0.25-sec delay before detonation of the fuze. A 3/25-in. rocket motor Mk 7 was unsatisfactory as a retro force when used with a 3-motor carriage on a 500-ft launcher; sufficient separation of the round before impact may have been obtained with a longer launcher. A 5-in. HVAR motor was suitable. A 3.25 in. retro motor was satisfactory for separation when a single 5-in. HVAR motor was used for propulsion. Six of 10 fuzes functioned after target impact with delay times of 0.29 to 0.75 sec. The sensitivity of the fuze could not be established because functioning on the mild steel and STS targets was not consistent.
