Part of the "triple T series" with the RIM-8 Talos and RIM-24 Tartar, the RIM-2 Terrier was the first operational short-to-medium range surface-to-air missile, developed by the U.S. Navy in the 1950s. The entire triple-T series has been replaced by the Standard SM missile series. Originally, that series, growing out of Navy Project Bumblebee, had the Talos as its focus, but delays in deploying the Talos led to developing the Terrier from a guidance test vehicle. It was replaced, to some extent, by the Tartar, and then the RIM-67 Standard SM-1, or the RIM-67 NTU versions for non-AEGIS ships.
Powered by a booster and a sustainer solid rocket engine, the first versions could engage only subsonic targets at altitudes up to 12 km/40,000 feet. It could use a high explosive or nuclear warhead. The first versions were beam riders, but semi-active radar homing was on the later versions, which also added anti-shipping missile capability. The final version had 40 nmi/75 km range.
It was never used in combat.
