F-9 Cougar

The Grumman F9F/F-9 Cougar was developed by the Grumman Aerospace Corporation one-beam fighter-bomber of the United States Navy. It was developed from the F9F Panther.


After the commissioning of the F9F Panther you started to develop a swept-wing variant of this airplane. Although the designation F9F shows the relationship with the Panthers, but actually the Cougar was a completely new aircraft. The main differences to the Panthers were the swept-wing, but it was also the engine replaced and due to the new wing and structural changes were necessary. The wing had a sweepback angle of 35 °, instead of spoiler ailerons, larger flaps, slats and stall fences. In November 1952, the first machine was put into service. The TF - 9J pattern flew many missions in the Vietnam War. The Cougar was used after they are decommissioned as Drohnenleitflugzeug. In addition, both the Panthers and the Cougar was used in the 1950s by the Blue Angels for their aerobatics.
