The historic, lethal and combat-tested AC-130 gunship — known for attacking ISIS and Taliban fighters during close-air support high-risk combat missions — is getting a massive technological upgrade with newer weapons and avionics to increase the effectiveness of the attack platform and extend its service life into future decades, service officials said.

“AC-130 gunship work involves upgrading the plane with weapons, targeting systems and sensor packages,” Col. Robert Toth, Chief of Tactical Aircraft, Special Operations and Combat Search and Rescue Division, told Scout Warrior in an interview.

Early variants of the AC-130 gunship first entered combat in the late 1960s during the Vietnam war. Later variants served in the Gulf War, War on Terror and war in Afghanistan, among other missions.

The gunships, operated by both the Air Force and Special Operations Command, are often used to support Special Operations fighters on the ground engaged in combat.

The aircraft is known for its 105mm side-firing cannons which enable it fire from a side-axis position during close-in combat supporting ground troops. The AC-130 Gunship also has a 25mm Gatling gun and a 40mm weapon, according to Air Force statements.

The Lockheed-Boeing built aircraft uses four Allison T56-A-15 turboprop engines, each with 4,300 shaft horsepower; the 155,000-pound aircraft has a 132-foot wingspan and hits speeds of 300 miles per hour. Its crew consists of a pilot, co-pilot, navigator, fire control officer, electronic warfare officers, flight engineer, TV operator, infrared detection operator, loadmaster and four aerial gunners.
