The RIM-67 Standard ER (SM-1ER/SM-2ER) is an extended range surface-to-air missile (SAM) and anti ship missile originally developed for the United States Navy (USN). The RIM-67 was developed as a replacement for the RIM-8 Talos and systems deployed in the 1950s on a variety of USN ships.

RIM-67 SM-1 Extended Range

The RIM-67 SM-1ER was the Navy's replacement for RIM-8 Talos missile. The RIM-67 was reduced to the size of the earlier RIM-2 Terrier because of improved technology, and Terrier armed ships were adapted to employ the new missile. Ships carrying the SM-1ER were often still called Terrier ships even after the SM-1ER.

RIM-67 and RIM-156 SM-2 Extended Range

With the development of the SM-2MR a SM-2ER with a booster stage was developed. Because the RIM-67's first stage booster was very long, it could not fit into the Mk 41 VLS system, and thus could not be used with the Aegis weapon system, instead the SM-2ER was employed with the New Threat Upgrade equipped Terrier ships.

The RIM-156 Standard SM-2ER Block IV with the Mk 72 booster was developed to compensate for the lack of a long range SM for the Ticonderoga-class of Aegis cruisers. This configuration can also be used for Terminal phase Ballistic Missile Defense.[1]

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]

There was a plan to build a nuclear armed standard missile mounting a W81 nuclear warhead as a replacement for the earlier Nuclear Terrier missile (RIM-2D). The USN, having lost interest in such a weapon, rescinded the requirement in the 1980s and the project was canceled.[3]

A new generation of Standard extended range missiles is expected to become operational in 2011. This missile is covered in a separate article. Please see RIM-174 Standard ERAM for details.

Operational history

During the Iran–Iraq War (1980-1988) the United States had deployed Standard missiles to protect its navy as well as other ships in the Persian Gulf from Iranian attacks. According to the Iranian Air Force, its F-4 Phantom IIs were engaged by SM-2ERs but managed to evade them, with one aircraft sustaining non-fatal damage due to shrapnel.[4]

On April 18, 1988, during Operation Praying Mantis, the USS Simpson (FFG-56) fired four RIM-66 Standard missiles and the USS Wainwright (CG-28) fired two RIM-67 Standard missiles at Joshan, an Iranian (Combattante II) Kaman-class fast attack craft. The attacks destroyed the Iranian ship's superstructure but did not immediately sink it. (It went down later.)

Deployment

RIM-67 Standard was deployed on ships of the following classes, replacing the RIM-2 Terrier, and it never was VLS-capable. All of the ships used the AN/SPG-55 for guidance and the Mk-10 guided missile launching system for the launcher. Later, SM-2ER missiles needed illumination of the target from the AN/SPG-55 only for terminal intercept, using inertial guidance for the rest of the interception.

The RIM-156 Standard Block IV, uses the Mk-41 VLS, the AN/SPY-1 radar for uplink and mid-course guidance, and the AN/SPG-62 for terminal guidance.

The last vessel to operate the RIM-67 was the Italian cruiser Vittorio Veneto (550) which was retired in 2003.
