Which aircraft is the E-3A Sentry?

• A. Gulfstream
• B. Boeing 777
• C. B1 Lancer
• D. E-3A Sentry

Answer: (D)

This question tests your ability to recognize an AWACS (Airborne Warning and Control System) aircraft. The E-3A Sentry is the airborne warning and control aircraft, built on a Boeing 707 airframe, and it’s instantly recognizable by its large rotating radar dome mounted above the fuselage. That radar system provides 360-degree airborne surveillance and vectoring for fighters and other aircraft, which is what sets it apart from ordinary transport or bomber aircraft. The other options are not AWACS: Gulfstream is a small business jet, Boeing 777 is a civilian wide‐body airliner, and B-1 Lancer is a bomber without the distinctive radar dome.
