The F-14A was the initial two-seat, twin-engine, all-weather interceptor fighter variant for the U.S. Navy. It first flew on 21 December 1970. The first 12 F-14As were prototype versions[162] (sometimes called YF-14As). Modifications late in its service life added precision strike munitions to its armament. The U.S. Navy received 558 F-14A aircraft and 79 were received by Iran.
