What is the designation of the Harrier II?

• A. AV-8B
• B. F-16
• C. A-10
• D. F-35B

Answer: (A)

The Harrier II carries the designation AV-8B. In this system, the letters spell out the aircraft’s role and capabilities: A for Attack, V for vertical/short takeoff and landing, and the 8 indicates the model series within that family, with B signifying a specific variant. The Harrier II is the upgraded version of the original Harrier, designed to meet Marine Corps needs with a larger airframe, a redesigned wing, and a more powerful engine for true V/STOL close air support.

For context, this designation distinguishes it from other aircraft listed: the F-16 is a conventional fighter, the A-10 Thunderbolt II is a dedicated close air support aircraft with a different designation, and the F-35B is a newer stealth STOVL fighter.
