LIM-49 Spartan : ウィキペディア英語版 | LIM-49 Spartan
The LIM-49A Spartan was a United States Army anti-ballistic missile, designed to intercept attacking nuclear warheads from Intercontinental ballistic missiles at long range and while still outside the atmosphere. For deployment, a defensive five-megaton atomic warhead was planned to destroy the incoming ICBM.〔http://nuclearweaponarchive.org/Usa/Weapons/Allbombs.html〕 It was part of the Safeguard Program. Spartan was the ultimate development in a long series of missile designs from the team of Bell Laboratories and Douglas Aircraft Company that started in the 1940s with the Nike. Spartan was developed directly from the preceding LIM-49 Nike Zeus, retaining the same tri-service identifier, but growing larger and longer ranged, from the Zeus' to about . Spartan was initially developed as part of the Nike-X project, later becoming the Sentinel Program. This was eventually cancelled and replaced with the much smaller Safeguard Program. Spartans were deployed as part of the Safeguard system from October 1975 to early 1976. ==History==
