"well its that Hercules aircraft, but then some smelly drunk gunners got their hands on it, cut a hole in the side and put a 105mm M102 howitzer on it. Flying gunners? Im not sure about this one boss"

The AC-130 gunship is a heavily-armed ground attack airplane. The basic airframe is manufactured by Lockheed, and Boeing is responsible for the conversion into a gunship and for aircraft support. It is a variant of the C-130 Hercules transport plane. The AC-130 Gunship II superseded the AC-47 Gunship I in Vietnam.

The gunship's sole user is the United States Air Force, which uses AC-130H Spectre and AC-130U Spooky variants. The AC-130 is powered by four turboprops and has an armament ranging from 20 mm Gatling guns to 105 mm howitzers. It has a standard crew of twelve to thirteen Airmen, including five officers (two pilots, a navigator, an electronic warfare officer and a fire control officer) and enlisted personnel (flight engineer, electronics operators and aerial gunners).

The US Air Force uses the AC-130 gunships for close air support, air interdiction, and force protection. Close air support roles include supporting ground troops, escorting convoys, and flying urban operations. Air interdiction missions are conducted against planned targets and targets of opportunity. Force protection missions include defending air bases and other military facilities. The gunship squadrons are part of the Air Force Special Operations Command.

Upgrades

A new program has been initiated to upgrade the armament of existing AC-130s still in service. The 25 mm GAU-12/U and 40 mm Bofors are to be replaced with two Mk 44 Bushmaster II 30 mm cannons.[11] The first aircraft is completed, with three more to join the fleet by December 2007, and fleetwide modifications complete by 2010. There are also plans to look into replacing the M102 howitzer with a breech-loading 120 mm mortar, and to give the AC-130 a standoff capability using either the AGM-114 Hellfire missile, the Advanced Precision Kill Weapon System (based on the Hydra 70 rocket), or the Viper Strike glide bomb.

The Air Force has decided to use the Bushmaster for two reasons. First, the 40 mm Bofors gun is becoming progressively more difficult to maintain, with spare parts becoming more difficult to locate. Second, the 25 mm cannon, while a useful weapon, lacks ammunition with an air-burst capability and suffers from too much scatter; procuring the most desirable types of ammunition for the 30 mm Bushmaster is much easier.


Ammunition

The PGM-38/U Enhanced 25mm High Explosive Incendiary (HEI) round was created to expand the AC-130U gunships' mission in standoff range and survivablility for its GAU-12/U 25mm gun system. This round a combination of the existing PGU-25 HEI and a M758 fuse designated as FMU-151/B to meet the MIL-STD-1316. The FMU-151 has an improved arming delay with multi-sensitive range.
