The F-111B was not ordered into production and the F-111B prototypes were used for testing before being retired. The planned F-111B was replaced by the smaller and lighter Grumman F-14 Tomcat, which carried over the AWG-9 radar/Phoenix missile system, engines, and a similar swing-wing configuration.
The swing-wing configuration, TF-30 engines, AIM-54 Phoenix air-to-air missiles and AWG-9 radar developed for the F-111B were used on its replacement, the Grumman F-14 Tomcat. The Tomcat was large enough to carry the AWG-9 and Phoenix missiles while exceeding both the F-111's and the F-4's maneuverability.
The AIM-54 Phoenix, developed for the F-111B fleet air defense fighter, had an airframe with four cruciform fins that was a scaled-up version of the AIM-47. One characteristic of the Missileer ancestry was that the radar sent it mid-course corrections , which allowed the fire control system to " loft " the missile up over the target into ...
The General Dynamics–Grumman EF-111A Raven is a retired electronic-warfare aircraft designed to replace the EB-66 Destroyer in the United States Air Force. Its crews and maintainers often called it the "Spark-Vark", a play on the F-111's "Aardvark" nickname.
Grumman's first jet aircraft was the F9F Panther; it was followed by the upgraded F9F/F-9 Cougar, and the F-11 Tiger in the 1950s. The company's big postwar successes came in the 1960s with the A-6 Intruder and E-2 Hawkeye and in the 1970s with the Grumman EA-6B Prowler and F-14 Tomcat .
However, due to reliability issues with the intended Pratt & Whitney F401 engines and the intent to incorporate as many of the systems of the failed Navy version of the F-111, the F-111B, into the project, it was deemed that the initial production run of F-14s utilize the F-111B's powerplant. The F-14A's thrust-to-weight ratio was similar to ...
As F-111 development continued, stall issues arose in certain parts of the flight regime; these were addressed by modifying the engine inlet in 1965–66, ending with the "Triple Plow I" and "Triple Plow II" designs. [12] The F-111B was cancelled by the Navy in 1968 due to weight and performance deficiencies. [13]
The Grumman F-14 Tomcat is an American carrier-capable supersonic, twin-engine, two-seat, twin-tail, all-weather-capable variable-sweep wing fighter aircraft.The Tomcat was developed for the United States Navy's Naval Fighter Experimental (VFX) program after the collapse of the General Dynamics-Grumman F-111B project.
