The Grumman F11F-1F Super Tiger (company designation G-98J) is a single-seat fighter aircraft originally developed for the United States Navy (USN).

[citation needed] As an improvement to the F11F-1 (F-11A) fighter, Grumman proposed a more advanced version of the airframe known as the F11F-1F Super Tiger.

[citation needed] For varying reasons, this campaign was unsuccessful, including the fact that the Super Tiger had not been accepted by the US government for any of the US services.

In a tender to equip the Swiss Air Force, the Super Tiger competed with the Saab Draken, Lockheed F-104 Starfighter, Dassault Mirage III, and Fiat G.91.

[citation needed] With an eye to the possibility of an order from West Germany in particular, Grumman offered to build a variant with the proven and more powerful 10,500 lbf (47 kN) Rolls-Royce Avon, instead of the J79.
