Definition
The RIM-2 Terrier was a medium-range surface-to-air missile (SAM) developed by the United States Navy during the 1950s for fleet air defense.
Overview
The RIM-2 Terrier was designed and deployed as part of the U.S. Navy's efforts to provide effective anti-aircraft defense against high-speed aircraft and incoming threats during the Cold War era. It entered service in 1956 and served as a key component of naval air defense systems through several modernized variants. The missile was primarily launched from cruiser and destroyer platforms equipped with the Terrier missile system, typically using twin-arm launchers.
Developed by Convair (later General Dynamics), the RIM-2 evolved from earlier experimental missile projects, notably the Bumblebee program, which aimed to create a viable shipborne missile system capable of intercepting enemy aircraft before they could threaten naval vessels. Over time, the Terrier system was upgraded to improve guidance, range, and reliability, with variants including the Terrier BT-3 (Basic Terrier), AT (Advanced Terrier), and later NT (Nuclear-Terrier) versions.
The system employed beam-riding guidance in its early versions, where the missile followed a radar beam directed at the target. Later models incorporated semi-active radar homing (SARH), allowing for greater engagement flexibility and accuracy. The RIM-2 Terrier was eventually phased out in the 1980s, superseded by the RIM-67 Standard missile (Extended Range Standard), which offered improved performance and compatibility with the Aegis combat system.
Etymology/Origin
The name "Terrier" follows the U.S. Navy's tradition of naming missile systems after dogs. It does not carry a technical acronym but is a continuation of a naming convention also seen in systems like the Talos, Tartar, and later Standard missiles.
Characteristics
- Launch Platform: Naval surface combatants (cruisers and destroyers)
- Propulsion: Solid-fuel rocket booster with a sustainer motor
- Range: Initially approximately 10 nautical miles (19 km); later versions extended to 20–25 nautical miles (37–46 km)
- Speed: Supersonic (Mach 3+ in later variants)
- Guidance: Early versions used beam-riding; later versions used semi-active radar homing
- Warhead: High-explosive fragmentation, with some variants equipped with a nuclear warhead (W45, yield ~1–5 kilotons)
- Service Period: 1956–1980s
