American surface-to-air missile. Extended-range surface-to-air missile for use by AEGIS naval vessels. A version with lower tier anti-missile capability against tactical ballistic missiles was tested but not put into production.

The requirement for the Standard Missile SM-2ER Block IV was to provide an extended-range surface-to-air missiles that could be launched from Navy AEGIS ships equipped with the new MK 41 Vertical Launch System. The original Standard ER missile could only be launched from the rail-type launchers that equipped older US vessels. In order to fit into the VLS launch tubes, the SM-2ER Block IV used a new, shorter but fatter MK 72 booster motor, and dispensed with the control fins on the original missile. Instead the missile used thrust-vector control. The missile was upgraded to include the MK 45 MOD 10 Target Detection Device, for improved performance against high-performance, stealthy targets even under severe jamming environments. The Block IV eventually evolved into the Block IVA Navy Area Theater Ballistic Missile Defense missile.

Problems with MK 72 booster delayed the program. The first launch in December 1992 was 18 months behind schedule. Priority given to development of the anti-missile version further delayed the program, and Initial Operational Capability for the Block IV was only certified in August 1999.

The Block IVA retained all anti-air warfare capabilities of the A model but added an anti-missile capability through use of a dual-mode RF/IIR seeker, an upgraded MK 125 warhead package, and an enhanced autopilot. Flight tests began in 1994, and in January 1997, a Lance tactical missile was shot down for the first time. The missile was to have been part of a two-tier ABM system, with the more capable Standard SM-3 as the upper tier. However the decision was taken to proceed with the SM-3 alone in December 2001 and the Block IVA program was cancelled.

Associated Launch Sites
  • White Sands White Sands Missile Range occupies an area 160 x 65 km in the Tularosa Basin of southern New Mexico, across the Sacramento Mountain range from Roswell. In the 1930's, Robert Goddard, after surveying weather conditions and population densities, had selected Roswell for his pioneering rocket tests. White Sands, a true desert area, was even more unpopulated than Roswell. German advances in rocketry during World War II impelled the US Army to begin programs to exploit this technology. The White Sands Proving Ground was established for testing German and American long-range rockets on 9 July 1945. Seven days later the first atomic bomb was exploded at Trinity Site, near the north boundary of the range. The first launch of a Tiny Tim rocket was on 26 September 1945. On 11 October a Tiny Tim boosted a WAC Corporal rocket from the tower. This was the first use of Launch Complex 33, later to be used for V-2, Nike, Viking, Corporal, Lance and Multiple Launch Rocket System testing. More...
  • Barking Sands Military missile test and sounding rocket launch site. In use from 1962 to present. Sandia National Laboratories operates the Kauai Test Facility for the Department of Energy and, through inter-Service Support Agreements provides the Barking Sands Pacific Missile Range Facility with rocket launch services for target systems and upper atmosphere measurements. PMRF/KTF is recognized in the INF Treaty as an authorized site from which launches of the STARS missile can be conducted. The site was recently involved in anti-ballistic missile tests. Known to have been used for 2320 launches from 1962 to 2007, reaching up to 1000 kilometers altitude. More...
  • White Sands LC35 Standard-ER, Black Brant, Aerobee launch complex. Work on LC-35 was begun by the US Navy in 1946. Although no specific requirement had been identified, Captain Robert McLaughlin of the Bureau of Naval Ordnance realized the Navy would need an instrumented range to test the surface-to-air missiles planned for Navy ships. The first facilities built were a blockhouse and two launch towers for Aerobee sounding rockets. From 1947 a total of 675 Aerobees were launched from White Sands, most of these from LC-35. More...
