The Convair RIM-2 Terrier was a two-stage medium-range naval surface-to-air missile (SAM), among the earliest SAMs to equip United States Navy ships. It underwent significant upgrades while in service, starting with beam-riding guidance with a 10-nautical-mile (19 km) range at a speed of Mach 1.8 and ending as a semi-active radar homing (SARH) system with a range of 40 nmi (74 km) at speeds as high as Mach 3. It was replaced in service by the RIM-67 Standard ER (SM-1ER).
Terrier has also been used as the base stage for a family of sounding rockets, beginning with the Terrier Malemute.
