Due to lowered wing loading its low and medium speed turn rate was improved with the exception of stall speed which is higher, 217 km/h IAS with landing flaps. The Cougar wings' shape was changed a lot, the wing area was also increased. The other aspect that has been slightly improved over the F9F-5 is climb rate, now can reach 29 m/s at sea level with full fuel tanks and increases to ~38 m/s with 20 minutes of fuel, it will not be able to out climb most of jet fighters from other nations at similar battle rating.įlying at full power is limited to 30 minutes of operation until the engine overheats and can fly at 95% of power indefinitely. The level acceleration is almost the same compared to previous versions, but since it is faster it gets better above 850 km/h. Its speed limit is also higher: 1127 km/h IAS.
It increased the level speed to 1041 km/h and when the plane carries four AIM-9B missiles it is 991 km/h at sea level, which is still slower than a MiG-15 or F-86. The F9F Cougar is a further improvement of the F9F series with the main changes that are changed wings, now being swept and a new more powerful engine, the Pratt & Whitney J48-P-8A.
