Open-ended Terms T369 fuzes, 105mm, T388 projectiles, Muzzle burst, M2 howitzers, Beehive. Tests were conducted on the muzzle burst feature of the MT T369 fuze. Twenty-five inert T388 shell were equipped with the MT T369 fuze and tested for direct fire, zero time performance. welve rounds were fired at Zone 10 charge and satisfactory muzzle burst fuze functioning was evidenced somewhere between 11.5 and 17 feet from the muzzle on six of the twelve tests. The other six rounds functioned at impact. Four rounds were fired at a charge to give 115 of rated pressure. Each of these performed satisfactorily giving bursts 14 to 17 feet from the muzzle. Five rounds were fired at Zone 10 charge conditioned at 140 F. Each of these functioned properly between 10 and 13 feet from the muzzle. Two rounds at Zone 9 charge and two rounds at Zone 7 charge functioned normally at 6 to 7.5 feet from the muzzle. No definite reasons for the failures were ascertained from the recovered parts of this test. Author
