RIM-67 Standard
extended range surface-to-air missile
The RIM-67 Standard ER (SM-1ER/SM-2ER) is an extended range surface-to-air missile (SAM) with a secondary anti-ship capability, developed for the United States Navy (USN) by Raytheon. The RIM-67 was developed from the RIM-66 Standard as replacement for the RIM-8 Talos long-range and RIM-2 Terrier medium-range missiles, which were 1950s systems deployed on a variety of USN ships. The RIM-66 Standard MR was essentially the same missile without a booster stage designed to replace the RIM-24 Tartar, another early medium-range missile. The RIM-66/67 series thus became the US Navy's universal SAM system, hence the designation "Standard Missile".
RIM-67A SM-1 Extended Range
The RIM-67A (SM-1ER Block I) was the Navy's replacement for RIM-8 Talos missile. Improved technology allowed the RIM-67 to be reduced to the size of the earlier RIM-2 Terrier missile. Existing ships with the Mk86 guided missile fire control system, or "Terrier" were adapted to employ the new missile in place of the older RIM-2 Terrier missile. Ships that switched from the RIM-2 Terrier to the RIM-67A were still referred to as Terrier ships even though they were equipped with the newer missile.
RIM-67B and RIM-156 SM-2 Extended Range
The second generation of Standard missile, the Standard Missile 2, was developed for the Aegis Combat System and for the New Threat Upgrade (NTU) program for existing Terrier and Tartar ships. It is the primary anti-air weapon of the US Navy.

Why this record matters
The phrase “extended range surface-to-air missile” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 23, 2026. The linked authority identifier is Q1136147. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
