Mk 11 missile launcher

The Mk-11 guided missile launching system (GMLS) is a twin-arm missile launcher designed for use on frigates and other military vessels.

The launcher could use the RIM-24 Tartar or RIM-66 Standard missile. Used on Albany class cruisers and the first thirteen Charles F. Adams class destroyers. The destroyers had one launcher at the rear of the ship while the cruisers had 2 launchers mounted amidships on either side of the ship. New Threat Upgrade added the ability to launch RGM-84 Harpoon anti-ship missiles.
