F-14 Tomcat






F-14 Tomcat is one of the most famous American hunters of the end of the 20th
century, made popular by many novels and films, of which memorable Top Gun. This imposing two-seater was designed at the end of the years 1960 for the defense of the fleets of aircraft carrier, the project of a navalized version of F-111 Aardvark not having given satisfactory results. The aerofoil with variable arrow of Tomcat facilitates takeoff and the landing, while allowing a high dash speed for the missions of interception. One of the principal assets of this apparatus resides in its radar at long range: F-14 can urge a aggressor before itself to be located, thanks to a radar Hughes AWG-9 who can follow 24 targets and attack of them 6 simultaneously very continuously to sweep space on 3 dimensions. F-14 is armed with a Vulcan gun of 20 mm and can carry an offensive load of 5900 kg, composed of air-to-air missiles of all the ranges as well as smooth and guided bombs. The privileged air-to-air weapon of Tomcat is remarkable missile AIM-54 Phoenix, of a range of 160 km. Even at the time of the Cold war, little country could be allowed to acquire this very expensive hunter (approx. 38 M$), although very powerful. Tomcat was thus only exported with 80 specimens towards Iran, which wished to stop the frequent Soviet incursions into its airspace. Three principal versions were developed. The F-14A is the first generation, been driven by engines Pratt & Whitney TF-30. Those posed some problems and were replaced by of General Electric F110 on the following versions. The F-14B was either a F-14A remanufacturé or a new apparatus. In addition to new engines, certain improvements were made to its avionics. Lastly, since 1990, the version D was born, with an entirely new radar and a avionics. In order to replace A-6 Intruder, a version of named attack Super Tomcat was also studied, but the program was finally cancelled with the profit of the F/A-18E/F Super Hornet. The F-14 last should remain in service until 2008 in US Navy.
