VAH-123, known as the "Professionals," was a U.S. Navy Heavy Attack Squadron established in June 1957 at NAS Whidbey Island, Washington. Its primary mission was to serve as a Fleet Replacement Squadron, training aircrews and maintenance personnel for the A-3 Skywarrior aircraft. Throughout its service, VAH-123 played a crucial role in preparing crews for heavy attack operations during the Cold War era. The squadron was disestablished on February 1, 1971, with its training responsibilities transferred to other units.
