In a U.S. military aircraft designator, which letter denotes Cargo Transport?

• A. T - Tanker
• B. E - Experimental
• C. C - Cargo Transport
• D. R - Research

Answer: (C)

In U.S. military aircraft designators, the mission letter after the hyphen shows the primary role of the aircraft. Cargo Transport is indicated by the letter C, which you can see in examples like C-130 and C-17, both well-known cargo transports. The other letters map to different roles: T stands for Tanker, E for Experimental, and R for Research. So the letter C uniquely signifies cargo transport in the designation system.
