M117 GP 750lb BOMB

The M117 is an air-dropped demolition bomb used by United States military forces. The weapon dates back to the Korean War of the early 1950s. Although it has a nominal weight of 750 pounds (340 kg) its actual weight, depending on fuze and retardation options, can be around 820 pounds (372 kg). The bomb's explosive content is typically 386 pounds (175 kg) of Tritonal or 377 pounds (171 kg) of Minol in the case of the M117A1E2 due to their higher density and detonation velocity compared to TNT. Demolition bombs rely on time delayed fuzes which allow the bomb to burrow into a building or other structure before detonating.  From the 1950s through the early 1970s the M117 was a standard aircraft weapon, carried by the F-100 Super Sabre, F-104 Starfighter, F-105 Thunderchief, B-57 Canberra, F-111, F-5, A-1 Skyraider, A-4 Skyhawk and F-4 Phantom. The M117 series was used extensively during the Vietnam War, and B-52G Stratofortress aircraft dropped 44,600 M117 and M117R bombs during Operation Desert Storm.
