The RIM-66 Standard MR (SM-1MR/SM-2MR) is a medium-range surface-to-air missile (SAM), with a secondary role as anti-ship missile, originally developed for the United States Navy (USN). The SM-1 was developed as a replacement for the RIM-2 Terrier and RIM-24 Tartar that were deployed in the 1950s on a variety of USN ships. The RIM-67 Standard (SM-1ER/SM-2ER) is an extended range version of this missile with a solid rocket booster stage.

The Standard missile program was started in 1963 to produce a family of missiles to replace existing guided missiles used by the Terrier, Talos, and Tartar guided missile launch systems. The intention was to produce a new generation of guided missiles that could be retrofit to existing guided missile systems.

The RIM-66A is the medium ranged version of the Standard missile and was initially developed as a replacement for the earlier RIM-24C as part of the Mk74 "Tartar" Guided Missile Fire Control System. It used the same fuselage as the earlier Tartar missile, for easier use with existing launchers and magazines for that system. The RIM-66A/B while looking like the earlier RIM-24C on the exterior is a different missile internally with redesigned electronics and a more reliable homing system and fuse that make it more capable than its predecessor. The RIM-66A/B Standard MR, (SM-1MR Block I to V) was used during the Vietnam War. The only remaining version of the Standard missile 1 in service is the RIM-66E (SM-1MR Block VI). While no longer in service with the USN, the RIM-66E is still in service with many navies globally and is expected to remain in service until 2020.

The RIM-66C/D Standard MR (SM-2MR Block I) was developed in the 1970s and was a key part of the Aegis combat system and New Threat Upgrade (NTU). The SM-2MR introduced inertial and command mid-course guidance. The missile's autopilot is programmed to fly the most efficient path to the target and can receive course corrections from the ground. Target illumination for semi-active homing is needed only for a few seconds in the terminal phase of the interception. This capability enables the Aegis combat system and New Threat Upgrade equipped vessels to time share illumination radars, greatly increasing the number of targets that can be engaged in quick succession. Mk 41 VLS adopts modular design concept, which result in different versions that vary in size and weight. There are three lengths: 209 in (530 cm) for the self-defense version, 266 in (680 cm) for the tactical version, and 303 in (770 cm) for the strike version. The empty weight for an 8-cell module is 26,800 lb (12,200 kg) for the self-defense version, 29,800 lb (13,500 kg) for the tactical version, and 32,000 lb (15,000 kg) for the strike version.
