Standard Missile (SM-1) fired from USS ''Nicholas'' against a supersonic target near Puerto Rico
The 'Standard Missile' is a type of 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 systems deployed in the 1950s on a variety of USN ships. 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 Vertical Launching 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 standard missile was designed and integrated by the Standard Missile Company (SMCo), jointly owned by Hughes Missile Systems Company and Raytheon Company. SMCo is the prime contractor for Standard Missile.[1] The SM-1 and SM-2 were continuously upgraded through Blocks (see below).

Versions of the Standard missile were used as the basis for the Aegis Ballistic Missile Defense System. Two were initially developed, the "Navy Area" and "Navy Theater-Wide". The "Navy Area" system was canceled by the United States Department of Defense due to delays in its development and cost-growth. "Navy Theater-Wide" continues under another name as part of the Missile Defense Agency's family of systems. The Navy has tested the RIM-156 Standard SM-2ER Block IV and RIM-161 Standard SM-3 for ballistic missile defense usage.
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] At one time it was planned to mount a W81 nuclear warhead, but this development was later shelved. The air launched AGM-78 Standard ARM and the ship launched RGM-66 Standard ARM were variants used as anti-radiation missiles in the 1970s.

RIM-67 SM-2 Extended Range
The RIM-67 SM-2ER was the Navy's replacement for RIM-2 Terrier missile. Ships carrying the SM-2 ER were often still called Terrier ships even after the SM-2ER. 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. The SM-2 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.

SM-6 ERAM, the future Standard Missile
The SM-6 ERAM (Extended Range Active Missile) is an under development upgraded version of the SM-2 designed to hit both aircraft and high performance cruise missiles. The missile combines the proven SM-2 airframe with a seeker from an AIM-120 AMRAAM missile. By utilizing the seeker from the AIM-120 AMRAAM missile, the SM-6 can offer the capability to hit targets outside the ships radar horizon, and therefore offer increased range as well as accuracy. The missile also takes advantage of both the SM-2 and AIM-120 AMRAAM's datalinking capability, and because it requires very little development is expected to be inexpensive to procure.
