Reconnaissance Attack (Heavy) Squadron 11 (RVAH-11), known as the "Checkertails," was a United States Navy squadron established in 1951 as VC-11 and later redesignated RVAH-11 in 1966. Initially flying the AJ Savage, the squadron transitioned to the A3D Skywarrior, and ultimately to the RA-5C Vigilante for high-speed, high-altitude reconnaissance missions. RVAH-11 played a significant role during the Vietnam War, conducting vital photo-reconnaissance missions over hostile territory from aircraft carriers. The squadron was disestablished on June 1, 1975, as the Navy phased out the Vigilante and reorganized its reconnaissance assets.
