The Mark 26 Guided Missile Launching System (GMLS) was a United States Navy fully automated system that stows, handles, and launches a variety of missiles. The system supported RIM-66 Standard, RUR-5 ASROC, and potentially other weapons. The Mark 26 had the shortest reaction time and the fastest firing rate of any comparable dual arm shipboard launching system at the time. With only one man at the control console, a weapon can be selected, hoisted to the guide arm, and launched. Several mods (0 to 5) provided magazine capabilities of 24 to 64 missiles.
