The Grumman F11F Super Tiger (company designation G-98J) was a single-seat fighter aircraft originally developed for the [Vous devez être inscrit et connecté pour voir ce lien] (USN).

Based on the USN's [Vous devez être inscrit et connecté pour voir ce lien], the F11F did not proceed beyond the two F11F-1F prototypes.

Design and development


In addition to the F-11A (F11F-1) fighter, Grumman also proposed a more advanced version of the airframe known as the F11F-1F Super Tiger.

This was the result of a 1955 study to fit the new [Vous devez être inscrit et connecté pour voir ce lien] engine into the F-11 airframe.

The aircraft first flew on 25 May 1956, reaching Mach 1.44 in one of the flights.

After addition of 60° wing root fillets, a 13.5 in (35 cm) fuselage extension, and an uprated J79 engine, the F11F-1F reached an impressive Mach 2.04.

This was a surprise even to Grumman, which had expected a top speed of only Mach 1.4 at altitude.

The Mirage III was finally chosen as a cheaper and more secure alternative, yet a close second in terms of performance.

The German [Vous devez être inscrit et connecté pour voir ce lien], [Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien] showed considerable interest but eventually the Lockheed F-104 Starfighter was chosen.

This outcome, however, was marred by the [Vous devez être inscrit et connecté pour voir ce lien], in which huge sums were paid by Lockheed to influential politicians in those countries to ensure the adoption of the Starfighter.
