This 20mm SUU-23 Gear Clutch is an original military-pattern component associated with the SUU-23/A 20mm gun pod, one of the best-known external gun pods of the Vietnam and Cold War era. Identified by Part Number 11699908 and FSN 1005-948-5320, this is a correctly identified U.S. aircraft armament part tied to the gun-pod family built around the 20mm Vulcan system.
The SUU-23/A was developed as an improved external gun pod for aircraft lacking an internal cannon, most notably early gunless F-4 Phantom II variants. Unlike the earlier SUU-16/A, which used a ram-air turbine to power the gun, the SUU-23/A used a self-powered gun installation based on the GAU-4/A/M61A1 Vulcan family, allowing it to operate without the drag and airflow limitations of the SUU-16 system. The pod carried 1,200 rounds of 20x102mm ammunition and became one of the defining U.S. gun-pod systems of the Vietnam era.
Because the SUU-23/A was built around the Vulcan family, its internal drive and operating hardware are specialized. Parts like this gear clutch belong to the internal mechanical group that helped the pod’s gun system operate correctly. These are the kinds of components that are often lost, separated, or discarded long before the larger pod assemblies disappear, which is exactly why originally identified examples are useful for restorers and collectors today.
Product Specifications:
Condition: Original surplus part
Part Number: 11699908
Federal Stock Number: 1005-948-5320
Compatibility: 20mm SUU-23/A gun pod / Vulcan-family gun system
Application: Original gear / clutch-related internal component for the SUU-23 system
Historical Significance:
The SUU-23/A represents an important stage in U.S. combat aviation armament. It was the improved answer to the lack of an internal gun on early missile-era fighters and saw combat use during the Vietnam War. Because it was based on the Vulcan system, SUU-23 components also belong to the broader history of one of the most recognizable American 20mm aircraft gun families ever fielded. Properly marked internal parts like this are useful not only as spare parts, but also as documentation of how those podded gun systems were built and supported.
Why This Part Matters:
Small internal pod and gun components are often harder to find than the major visible assemblies. A part like this is especially useful for:
Ideal For:
SUU-23/A gun pod restoration and reference projects
Aviation museums and static display restoration
Collectors of U.S. military aircraft armament
Technical parts-reference collections
Educational displays on Vietnam- and Cold War-era gun pods
