The AIM-174B Gunslinger is a very long-range air-to-air missile (AAM) developed by U.S. defense contractor Raytheon and used by the United States Navy (USN). The AIM-174B is a derivative of the RIM-174B 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-174B as the "Air-Launched Configuration" of the SM-6. The AIM-174B's existence was first revealed publicly in July 2024 at RIMPAC 2024 and has been confirmed to be capable of being carried and launched only by the Boeing F/A-18E/F Super Hornet.

Described as a "massive" AAM, the Gunslinger has a confirmed range of 150 miles (130 nautical miles or 240 kilometers), though it is widely speculated that the range may be much greater.

In addition to the AIM-174's air-to-air role, the Gunslinger is believed capable of engaging other missiles (including ballistic missiles and hypersonic weapons), and may also serve as an air-to-ground and anti-ship missile.
