....air-conditioned, and pressurized. Armament on the fighter version of the F9F consisted of four 20-mm cannons and two Sidewinder missiles. For ground-attack missions, the aircraft could carry up to four 500pound bombs.
A glance at the data in table V indicates that the maximum speed of the Cougar was nearly the same as that of the F-86 at an altitude of 35 000 feet; near sea level, the F-86 was about 30 miles per hour faster than the Cougar. Data in reference 200 show that the Cougar was 40-plus miles per hour faster than its straight-wing cousin the Panther. The higher performance of the swept-wing Cougar was achieved with about the same thrust as the straight-wing Panther in spite of a drag-producing increase of 35 percent in wing area. Together with the highlift devices on the Cougar, the larger wing area resulted in a stall speed of about 140 miles per hour for both aircraft (ref. 200).
