One of the world's most technologically advanced tactical missiles, the AIM-54 Phoenix was the first operational radar-guided air-to-air missile that could be launched in multiple numbers against different targets from an aircraft, making the Phoenix the Navy's main fleet air defense long-range weapon.
“The heart of the F-14 Tomcat (soon also to retire) weapons system is the Hughes AWG-9 fire control system, capable of tracking 24 targets and firing six AIM-54 Phoenix air-to-air missiles engaging six different targets,” said Capt. Scott Stewart, the Navy's program manager for Air-to-Air Missile Systems. “With a range of over 100 miles, the AIM-54 gave the F-14 the greatest stand-off engagement capability of any fighter in the world. For years, Soviet air crews flying Badger, Bear and Backfire bombers feared the unprecedented capabilities of the Phoenix Missile."
