Which statement correctly matches a gun system to its aircraft?

• A. GAU-21 on CV-22
• B. GAU-18 on F-35
• C. GAU-23 on HH-60
• D. M61A1/A2 on 25 mm

Answer: (A)

The gun systems are matched to aircraft by what each platform actually uses in service. The CV-22 Osprey is armed with a GAU-21, a .50-caliber machine gun, which is a known defensive/close-support gun for that aircraft. The other pairings don’t fit real configurations: the F-35’s internal cannon is a 25 mm GAU-22/A, not a GAU-18; the HH-60 typically uses other rotorcraft weapons rather than a GAU-23 on that platform; and the M61A1/A2 is a 20 mm Vulcan, not a 25 mm gun. So the only correct match among the options is the GAU-21 on the CV-22 Osprey.
