What does the designator B indicate in military aircraft?

• A. Cargo/Passenger
• B. Bomber
• C. Attack
• D. Electronic

Answer: (B)

In military aircraft designation systems, the first letter shows the aircraft’s primary mission. The letter B designates Bomber, meaning the airframe is built to deliver bombs against targets, typically in bombing roles from strategic to tactical. This is why you see aircraft like the B-52 or B-2 identified as bombers. It’s different from other mission prefixes: a designator for cargo would point to transport roles, a designator for attack would cover air-to-ground fighting with a broader fighting mission, and a designator for electronic would indicate electronic warfare or reconnaissance capabilities. So the B prefix specifically signals the bomber role.
