Grumman F11F-1F Super Tiger
prototype fighter aircraft
The Grumman F11F-1F Super Tiger (company designation G-98J) is a single-seat fighter aircraft originally developed for the United States Navy (USN). Based on the USN's F-11 Tiger, the F11F-1F did not proceed beyond the two F11F-1F prototypes.
Design and development
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. This was the result of a 1955 study to fit the new General Electric J79 engine into the F11F airframe. The Navy was sufficiently interested to authorize modification of two production F11F-1s with enlarged air intakes and YJ79-GE-3 turbojets, with the result being designated the F11F-1F, indicating a production F11F-1 with a special engine fit.
The aircraft first flew on 25 May 1956, reaching Mach 1.44 in one of the flights. After the 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 in 1957, thus becoming the first naval aircraft in the world to exceed Mach 2 (two years before the F4H, F8U-3, and A3J). This was a surprise even to Grumman, which had expected a top speed of only Mach 1.4 at altitude. By comparison, the F11F-1 with the Wright J65 had had difficulty exceeding Mach 1.1. However, the U.S. Navy did not order the Super Tiger into production.
The public source identifies “Grumman F11F-1F Super Tiger” as prototype fighter aircraft. This brief keeps that definition visible, then builds a research path around Grumman, F11F-1F and Super.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Grumman F11F-1F Super Tiger”, the useful work is to connect “prototype fighter aircraft” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Nov 21, 2025. The linked authority identifier is Q5217660. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1955, 1956 and 1957.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
