As the Korean War focused attention on advances in Russian aircraft technology, especially the MiG-15, the Navy sought a carrier fighter with better performance. The F-86 Sabre, which had developed from the original Fury, could easily defeat the MiG-15, and converting the Sabre into a carrier fighter led to the Fury family of jet aircraft. The FJ-4B, the last and definitive version, had a strengthened wing for the Martin Bullpup missile system, a Wright J65-W-1 6A Sapphire turbojet, the Low Altitude Bombing System from the Air Force F-86H for tactical nuclear weapon delivery, and an added second set of speed brakes to improve attack capability. Some 222 FJ-4Bs were produced from 1956 through 1958, and the aircraft was known for a roomy cockpit and excellent maneuvering, earning the nickname "Cadillac" from pilots, many of whom considered it a better attack platform than the A4D Skyhawk that replaced it. One FJ-4B, manufactured by North American Aviation in Columbus, Ohio, and delivered to the Navy in 1957, was assigned to Attack Squadron VA-116 Roadrunners, redesignated VA-144 Roadrunners during deployment on the USS Ranger in 1959, then deployed with VA-144 and VA-146 Blue Diamonds aboard the USS Oriskany in 1960 and aboard the USS Lexington from 1961 to 1962 before transfer to VA-216 Black Diamonds, later serving at various stateside stations and being surplused in 1965.
