21 December 1970: At the Grumman Aerospace Corporation plant, Calverton, Long Island, New York, Chief Test Pilot Robert Kenneth Smyth and Project Test Pilot William Howard Miller took off on the very first flight of the F-14A-1-GR Tomcat, Bu. No. 157980.

The F-14 is a long-range fleet defense interceptor designed to operate from the United States Navy’s aircraft carriers. It is a two-place, twin-engine Mach 2+ fighter. The most notable feature are its variable geometry wings (“swing wings”), similar to those of the General Dynamics F-111.

The Grumman F-14A Tomcat (Grumman has a long history of naming its fighter aircraft after various cats, e.g., Wildcat, Hellcat, Tigercat, Panther, Cougar, Tiger) is 62 feet, 8 inches (19.101 meters) long with its wingspan varying from 33 feet, 3 inches (10.135 meters) when swept fully aft (overswept), and 64 feet, 1 inches (19.510 meters) when fully extended. The airplane has an overall height of 16 feet, 0 inches (4.879 meters). It has an empty weight of 38,188 pounds (17,322 kilograms) and maximum takeoff weight of 72,566 pounds (32,915 kilograms).

The fighter was initially powered by two Pratt & Whitney JTF10A (TF30-P-412A) afterburning turbofan engines. The JTF10A is a two-spool axial-flow engine.  It has a 3-stage fan section, 13-stage compressor section (6 low- and 7 high-pressure stages) and 4-stage turbine (1 high- and 3 low-pressure stages). The engine has a Maximum Continuous Power rating of 10,800 pounds of thrust (48.041 kilonewtons) at 14,300 r.p.m. (N2); Intermediate Power, 12,350 pounds (54.936 kilonewtons) at 14,800 r.p.m. (45-minute limit); and a Maximum Power of 20,900 pounds (92.968 kilonewtons) at 14,780 r.p.m., with afterburner (45-minute limit). The engine is 18 feet, 7.59 inches (5.679 meters) long, 4 feet, 2.5 inches (1.283 meters) in diameter, and weighs 3,971 pounds (1,801 kilograms).
