General Dynamics F-111The General Dynamics F-111 "Aardvark" was the first variable geometry type of aircraft to reach a "quantity" production. The prototype F-111A first flew on December 21st, 1964. After many changes the F-111A entered service in 1967. It used two 82.3 kN (18,500 lbs. st.) Pratt & Whitney TF30-P-1 / 3 engines. Despite it's "F" designation, these were not used as fighters, rather all weather precision bombers. The F-111C used long span wings and strengthened landing gear. 24 of these were supplied to the RAAF (Royal Australian Air Force.) The F-111D included advanced Mark II Avionics, which increased the cost and maintenance. The F-111E is similar to the "A" model with enlarged engine intakes to be used in conjunction with the more powerful TF30 engine, which was never fitted. The F-111F is an improved tactical version of the aircraft, with two 111.5 kN (25,100 lbs. st.) TF30-P-100 engines and simplified avionics. There was an extended study on an improved model FB-111H to be fitted with General Electric F 101 engines, advanced avionics, and enlarged weapons bay, however this version also did not reach production. An intersting feature to look for on the F-111's are the inlet vortex generators hinged on the forewing just above the engine intakes. Specifications; Wing Span; (maximum sweep) 9.74 m.
