The Crusader became the ultimate "day fighter" operating off the aircraft carriers. At the time, U.S. Navy carrier air wings had gone through a series of day and night fighter aircraft due to rapid advances in engine and avionics. Some squadrons operated aircraft for very short periods before being equipped with a newer higher performance aircraft. The Crusader was the first post-Korean War aircraft to have a relatively long tenure with the fleet and like the USAF F-105, a contemporary design, might have stayed in service longer if not for the Vietnam war and resulting attrition from combat and operational losses.
