Specifications
The M114 was similar to a pipe bomb: it had a 530-millimetre (21 in) tube with a diameter of 41 mm (1+5⁄8 in).[1] 108 M114s were clustered into the M33 cluster bomb;[1] each had its own detonator and was ejected from the M33 while the bomb was still aloft.[4] Each M114 held 320 milliliters of Brucella suis.[1]
