 The Tartar Guided Missile Fire Control System, or Mk 74 Guided Missile Fire Control System, or just "Tartar", is a US-built medium-range anti-aircraft missile system.The French version used on Cassard class frigates is composed of a vertical rotating magazine holding 40 missiles, a Mk 13 launcher, two AN/SPG-51C fire-control radars and one DRBJ11 three-dimensional air search radar.Though the entire weapon system is commonly called Tartar, tracing back to its original linkage to the RIM-24 Tartar missile, it utilizes medium-ranged RIM-66 Standard missiles.
