Which gun is installed on the HH-60 aircraft and can be reloaded midair?

• A. M61 Vulcan
• B. M134
• C. GAU-18
• D. GAU-12

Answer: (C)

The capability being tested is knowing which gun on the HH-60 can be reloaded in flight. The HH-60 commonly uses a door-mounted GAU-18 .50 caliber machine gun, which is belt-fed from a removable ammunition drum. This feed system is designed to allow quick in-flight ammunition changes, so crews can swap drums or belts without landing, a crucial feature for long-range or rescue missions where staying airborne matters. The other options aren’t configured as the HH-60’s door gun in this role or don’t have the in-flight reloading arrangement: the M61 Vulcan is a 20mm cannon used on different aircraft and not standard on the HH-60; the M134 minigun is widely used but isn’t typically described as reloadable midair in this context; and the GAU-12 is a larger 25mm system not used on this helicopter. Thus, the GAU-18 best fits both the installation and the midair reload capability.
