The TARTAR Missile
The Tartar was born of a need for a more lightweight system for smaller ships, and something that could engage targets at very close range. Essentially, the Tartar was simply a RIM-2C Terrier without the secondary booster. The Tartar was never given a SAM-N-x designation, and was simply referred to as Missile Mk 15 until the unified Army-Navy designation system was introduced in 1963.
The Tartar was used on a number of ships, of a variety of sizes. Initially the Mk 11 twin-arm launcher was used, later ships used the Mk 13 and Mk 22 single-arm launchers. Early versions proved to be unreliable. The Improved Tartar retrofit program upgraded the earlier missiles to the much improved RIM-24C standard. Further development was canceled and a new missile, the RIM-66 Standard, was designed to replace it. Even after the upgrade to a new missile, ships were still said to be Tartar ships because they carried the Tartar Guided Missile Fire Control System.
