The AIM-174 is a long-range air-to-air missile (AAM) developed by U.S. defense contractor Raytheon and used by the United States Navy (USN). The AIM-174 is a derivative of the RIM-174 Standard Extended Range Active Missile (ERAM, Standard Missile-6, or SM-6) surface-to-air missile, a member of the extended Standard Missile family, with the USN describing the AIM-174 as the "Air-Launched Configuration"[10] of the SM-6. The AIM-174's existence was first confirmed to the public in July 2024 at RIMPAC 2024. The operational variant, the AIM-174B, is only known to be capable of being carried and launched by the Boeing F/A-18E/F Super Hornet as of July 2024.[11]

Since the 2004 retirement of the AIM-54 Phoenix AAM, the USN has not fielded a dedicated long-range air-to-air missile.[12] The AIM-174's existence had been speculated about since at least 2021, with photos of SM-6s carried by Super Hornets making their way online.[13] The publication Naval News reports that they were following developments of an "air-launched SM-6" since 2015,[14] while The Aviationist reports that photos of Super Hornets carrying "an SM-6 variant" appeared in 2018.[15]

Little is known about the missile as it is speculated that it was developed as a special access program,[16] similar to the AIM-260 Joint Advanced Tactical Missile[17] (of which little is officially known).[18] As the AIM-260 is similarly a very long-range air-to-air missile, it is unclear what the relationship between the AIM-174 and AIM-260 will be, as the USN has co-operated with the United States Air Force (USAF) in developing the latter for use by both services. Both missiles are designed to counter the extreme-range air-to-air missiles being fielded or under-development by the United States' peer and near-peer potential adversaries, such as the Russian Vympel R-37M or the Chinese PL-21.[19] Both the AIM-174 and -260 are separate from the currently under-development Long-Range Engagement Weapon of the USAF.

In essence, this new missile fills the gap left by the retirement of the AIM-54 Phoenix. The AIM-54 was a long-range air-to-air missile used by the U.S. Navy's F-14 Tomcat and retired in 2004 alongside the F-14. Known for its impressive range of over 100 nautical miles and multiple-target engagement capability, the AIM-54 left a significant void in long-range engagement capabilities.
