The RIM-67 Standard ER (SM-1ER/SM-2ER) is an extended range surface-to-air missile (SAM) 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.
[edit] RIM-67 SM-1 Extended RangeThe 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. [edit] RIM-67 and RIM-156 SM-2 Extended RangeWith 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. 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.[1] 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 The USN, having lost interest in such a weapon, rescinded the requirement in the 1980s and the project was canceled.[2] [edit] Operational historyDuring the Iran–Iraq War the United States had deployed Standard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.[3] 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.) [edit] DeploymentRIM-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. [edit] Surface to air variants
