The Grumman F9F/F-9 Cougar was a carrier-based fighter aircraft for the United States Navy and United States Marine Corps. Based on Grumman's earlier F9F Panther, the Cougar replaced the Panther's straight wing with a more modern swept wing. Thrust was also increased with the installation of a newer, more powerful engine. The Navy considered the Cougar an updated version of the Panther, despite having a different official name, and thus Cougars started off from F9F-6.

The U.S. Navy's flight demonstration team, the Blue Angels flew four different variants of F9Fs from the F9F-2 Panther to the F9F-8. The Blue Angels replaced their six F9F-5 Panthers with six F9F-6s in 1953. This was short lived however and the Navy subsequently took them for fleet use without using the planes in an air show. The F9F-6s were then replaced with overhauled F9F-5s until 1954 when the Blue Angels switched to the F9F-8. The Blue Angels used the F9F-8 until 1957 they were replaced by the Grumman F11F-1 Tiger, although one two-seat F9F-8T was retained for press and VIP flights.

The Diamond, in tight formation and usually at lower speeds (400 mph), performs maneuvers such as formation loops, rolls, and transitions from one formation to another. The Solos showcase the high performance capabilities of their individual aircraft through the execution of high-speed passes, slow passes, fast rolls, slow rolls, and very tight turns.
