RIM-24 Tartar

Part of the "triple T series" with the RIM-2 Terrier and RIM-8 Talos, the RIM-24 Tartar was an evolution of the Terrier, intended to be used on smaller ships, deployed by the U.S. Navy in the early 1960s. The entire triple-T series has been replaced by the Standard SM missile series. The Tartar, specifically, was replaced by the RIM-66 SM-1.

Essentially, the Tartar was a Terrier with improved electronics, weight reductions, and a better engine, but the booster engine removed to reduce its size. It could use a high explosive or nuclear warhead. It had shorter range than the Terrier, but more capability within that range, including an improved anti-shipping missile capability. It used semi-active radar homing, more effective than the Terrier against low-altitude targets. Tartars also improved anti-shipping missile capability. The final variant could engage targets at 20000 m (65000 ft) and 30 km (16 nm)

It was never used in combat.
