Also known as
  • M299 AUL
  • M299 All Up Launcher
  • M299 smart launcher
  • M299/M310 Longbow Missile Launcher
  • M310 launcher

The M299 Launcher is a U.S. reusable missile launcher family that provides the aircraft interface for AGM-114 Hellfire and AGM-179 JAGM-class weapons. Lockheed Martin and Marvin Engineering describe four-rail M299 and two-rail M310 configurations for rotary-wing, unmanned, fixed-wing, and surface integrations, with direct public conflict-use support limited to U.S. Apache use in Iraq.
