This is an original Metering Bomb R Orifice Assembly for the AC-130H Spectre Gunship, listed under Part Number 64D13176-7 and NSN 1095-00-911-8758. This highly specialized component is part of the precision ordnance delivery and bomb release control system used aboard the iconic AC-130H—one of the most heavily armed and versatile aircraft in U.S. Air Force history.

This assembly is new old stock U.S. military surplus. It remains in good unused condition and is an essential part for restorers, collectors of aviation ordnance hardware, or anyone maintaining documentation-quality accuracy in AC-130H system exhibits.

Historical Significance – The AC-130H Spectre Gunship

The Lockheed AC-130H Spectre was introduced in the early 1970s as a dedicated gunship variant of the C-130 Hercules, designed for close air support, armed reconnaissance, and interdiction missions. Operated primarily by the U.S. Air Force Special Operations Command (AFSOC), the AC-130H was fitted with a formidable array of weapons—including 20mm, 40mm, and 105mm guns—and an advanced fire control system.

Integral to its mission effectiveness was its internal bomb release and ordnance control system, which relied on components like the Metering Bomb R Orifice Assembly to precisely regulate the release of explosive ordnance. These systems were vital in ensuring controlled, accurate delivery during low-altitude night missions and coordinated strikes.

Retired in 2015 after decades of combat service across Vietnam, Grenada, Panama, Iraq, Afghanistan, and more, the AC-130H remains one of the most celebrated gunship platforms in military aviation history.
