Source-derived summary

The AGM-84H/K SLAM-ER (Standoff Land Attack Missile-Expanded Response) is an advanced stand off precision-guided, air-launched cruise missile produced by Boeing Defense, Space & Security for the United States Armed Forces and their allies. Developed from the AGM-84E SLAM (Standoff Land Attack Missile, itself developed by Boeing Integrated Defense Systems from the McDonnell Douglas Harpoon anti-ship missile), the SLAM-ER is capable of attacking land and sea targets medium to long range (over 155 nautical miles/270 km maximum). The SLAM-ER relies on the Global Positioning System (GPS) and infrared imaging for its navigation and control, and it can strike both moving and stationary targets.

The SLAM-ER can be remotely controlled while in flight, and it can be redirected to another target after launch if the original target has already been destroyed, or is no longer considered to be dangerous (command guidance). The SLAM-ER is a very accurate weapon; as of 2009 it had the best circular error probable (CEP) of any missile used by the U.S. Navy.

History

In 1999, Boeing and the U.S. Navy conducted a live fire of a SLAM-ER from an F/A-18 Hornet on the decommissioned USS Dale (CG-19) off the coast of Puerto Rico.

The SLAM-ER obtained initial operating capability in June 2000. A total of three SLAM-ER missiles were fired by the U.S. Navy during the Iraq War, and the missile was also used during Operation Enduring Freedom in Afghanistan.

The General Electric Company provides an Automatic Target Recognition Unit (ATRU) for the SLAM-ER that processes prelaunch and postlaunch targeting data, allows high speed video comparison (DSMAC), and enables the SLAM-ER to be used in a true "fire and forget" manner. It also includes a "man-in-the-loop" mode, where the pilot or weapons system officer can designate the point of impact precisely, even if the target has no distinguishing infrared signature.

Editorial summary

Begin with the source’s own compact description: “AGM-84H/K SLAM-ER” is air-launched cruise missile. The dossier treats that line as a proposition to test through AGM-84H, SLAM-ER and air-launched, not as a finished interpretation.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—2009, 1999, 2000—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, AGM-84H, SLAM-ER and air-launched is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “air-launched cruise 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.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 11, 2026. The linked authority identifier is Q15725781. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2009, 1999 and 2000.

Critical limits

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.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
