The Convair RIM-2 Terrier was a two-stage medium-range naval surface-to-air missile (SAM), and was among the earliest surface-to-air missiles to equip United States Navy ships. It underwent significant upgrades while in service, starting with a beam-riding system with 10 nautical miles (19 km) range at a speed of Mach 1.8, and ending as a semi-active radar homing system with a range of 40 nautical miles (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 a sounding rocket.
The Terrier was a development of the Bumblebee Project, the Navy's effort to develop a surface-to-air missile to provide a middle layer of defense against air attack (between carrier fighters and antiaircraft guns). It was test launched from USS Mississippi (AG-128) ex (BB-41) on January 28, 1953, and first deployed operationally on the Boston-class cruisers, USS Boston (CAG-1) and USS Canberra (CAG-2) in the mid-1950s, with Canberra being the first to achieve operational status June 15, 1956. Its US Navy designation was SAM-N-7 until 1963 when it was re-designated RIM-2.
For a brief time during the mid-1950s the USMC had two Terrier battalions equipped with specially modified twin sea launchers for land use that fired the SAM-N-7. The Terrier was the first surface-to-air missile operational with the USMC. The launchers were reloaded by a special vehicle that carried two Terrier reloads.
Initially, the Terrier used radar beam-riding guidance, forward aerodynamic controls, and a conventional warhead. It had a top speed of only Mach 1.8, a range of only 10 nautical miles (19 km), and was only useful against subsonic targets. Originally, the Terrier had a launch thrust of 23 kN (5,200 lbf), and weight of 1,392 kilograms (3,069 lb). Its original dimensions were a diameter of 340 mm, a length of 8.08 m, and a fin span of 1.59 m. Cost per missile in 1957 was an estimated $60,000.
