These are general-purpose (GP) high-explosive (HE) bombs which may use proximity, mechanical, or electric nose and tail fuzes. When used as an M117D (destructor), the M117 bomb has a fuzing system actuated by magnetic/seismic influence. Both fragmentation and blast effect are produced by these bombs.
Method of Operation
The M117-series bombs may be fitted with either a conical or retarded (Snakeye) fin assembly. All bombs may have an arming wire assembly, lanyard, or an electrical charging receptacle installed, depending on the fuzing employed. The charging well between the suspension lugs may be fitted with either an electrical charging receptacle with an arming safety switch installed or a lanyard, or closed by a plug to provide watertight integrity. The suspension lugs are 356 millimeters (14.00 inches) apart. The conical fin assemblies for the bombs have access doors, secured by quick-release fasteners, to give access to the tail fuze cavity. The arming/drive assembly for a mechanical fuze extends through the side of the fin assembly. The nose fuze cavity may contain either a fuze, a proximity sensing element, or a nose plug (with or without fuze).
The bombs are painted olive drab and have yellow markings which include the type of explosive charge, the national stock number (NSN), the average weight, and the year loaded.
