The RIM-66 Standard MR (SM-1MR/SM-2MR) is a medium range surface-to-air missile (SAM) 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 deployed in the 1950s on a variety of USN ships. It is similar to the RIM-67 Standard (SM-1ER/SM-2ER), but has no rocket booster.

[edit] Description

The RIM-66A/B Standard MR, (SM-1MR Block I to V) was used during the Vietnam War. It used the same fuselage as the earlier Tartar, for easier use with existing launchers and magazines. 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). In the early 1980s, the missile was deployed via Mk-41 Vertical Launch System (VLS) aboard the USS Bunker Hill, the first U.S. Navy ship to deploy a vertical launcher. VLS is now the predominant launcher used with the Standard missile in the U.S. Navy aboard Ticonderoga-class cruisers and Arleigh Burke-class destroyers. The SM-1 and SM-2 were continuously upgraded through Blocks (see below).

The Standard can also be used against ships, either at line-of-sight range using its semi-active homing mode, or over the horizon using inertial guidance and terminal infrared homing.^[2]

[edit] Contractors

Standard missiles were constructed by General Dynamics Pomona Division until 1992, when it became part of the Hughes Missile Systems Company. Hughes formed a joint venture with Raytheon called Standard Missile Company (SMCo). Hughes Missile Systems was eventually sold to Raytheon making it the sole contractor.^[3]

[edit] Operational History

On July 3, 1988, USS Vincennes (CG-49) shot down Iran Air Flight 655, an Airbus A300B2, using two SM-2MR missiles from her forward launcher,^[4] killing 290 people. The aircraft was mistaken for an Iranian F-14.

[edit] Deployment History

The Standard missile is designated by blocks depending upon their technological package.

[edit] SM-1 Medium Range Block I/II/III/IIII, RIM-66A

The First Standard missiles entered service in the USN in 1967. Blocks I, II, and III were preliminary versions. Block IIII was the production version. This missile was a replacement for the earlier RIM-24C Tartar missile.

[edit] SM-1 Medium Range Block V, RIM-66B

The RIM-66B introduced a new autopilot, rocket motor, and warhead.

[edit] SM-1 Medium Range Block VI, RIM-66E

The RIM-66E was the last version of the standard missile one medium range. This version entered service in 1983 ^[5]with the United States Navy and export customers. The RIM-66E armed the Oliver Hazard Perry class frigates, and was controlled by the Mk92 fire control system. The missile was withdrawn from USN service in 2003, but is still used by several other navies with the Digital Tartar Guided Missile Fire Control System. The RIM-66E is expected to remain viable until 2020.^[6]

[edit] SM-2 Medium Range Block I, RIM-66C/D

The RIM-66C was the first version of the Standard missile two. The missile became operational in 1978 with the Aegis combat system fitted to the Ticonderoga class cruiser. The RIM-66D was the SM-2 medium range block I version for the New Threat Upgrade. The SM-2 incorporates a new autopilot giving it inertial guidance in all phases of flight except for the terminal intercept where semi-active radar homing is still used. This version is no longer in service, remaining missiles have either been remanufactured into later models or have been put in storage.

[edit] SM-2 Medium Range Block II, RIM-66G/H/J

The Block II missile introduced in 1983 with a new rocket motor for longer range and a new warhead. The RIM-66G is for the Aegis combat system and the Mk26 missile launcher. The RIM-66H is for Aegis and the Mk41 vertical launcher. The RIM-66J is the version for the New Threat Upgrade.

[edit] SM-2 Medium Range Block III/IIIA/IIIB, RIM-66K/L/M

The RIM-66M is the version of the Standard missile two medium range (SM-2MR) currently in service with the USN aboard Ticonderoga class cruisers, and Arleigh Burke class destroyers. The missile is specifically designed for the Aegis Combat System and the Mk41 Vertical launch system. The Block III missiles differ from earlier blocks by the addition of the MK 45 MOD 9 target detecting device, for improved performance against low altitude targets. The Block IIIB missile additionally has a dual semi-active/infrared seeker for terminal homing. The dual seeker is intended for use in high-ECM environments, against targets over the horizon or with a small radar cross section.^[7] All USN Block III and IIIA missiles are to be upgraded to Block IIIB. Block IIIA missiles are operated by the Japanese Maritime Self-Defense Force on its Kongo class and Atago class Aegis destroyers, and is also by the Dutch and German Navies with the APAR air defense system. Block III variants for Aegis and arm launchers are designated RIM-66L. Block III missiles for New Threat Upgrade systems is designated RIM-66K. Block IIIB missiles were not produced for the New Threat Upgrade.

[edit] Deployment

RIM-66 Standard was deployed on ships of the following classes, replacing RIM-24 Tartar in some cases:

Charles F. Adams class destroyer (Mk74 Missile Fire Control)
Oliver Hazard Perry class frigate (Mk92 Missile Fire Control)
Kidd class destroyer (Mk74 Missile Fire Control SM-1/later New Threat Upgrade for SM-2)
California class cruiser (Mk74 Missile Fire Control SM-1/later New Threat Upgrade for SM-2)
Virginia class cruiser (Mk74 Missile Fire Control SM-1/later New Threat Upgrade for SM-2)
Ticonderoga class cruiser (Aegis Combat System/Mk99 Missile Fire Control)
Arleigh Burke class destroyer (Aegis Combat System/Mk99 Missile Fire Control)
RIM-66 has also been in service in other navies worldwide, mostly in ships of classes similar to those listed above.
