Polaris missile submarine program The Polaris missile was a submarine-launched, two-stage solid-fuel nuclear-armed ballistic missile (SLBM) built during the Cold War by Lockheed for the United States Navy. Known as a Fleet Ballistic Missile (FBM), it first flew from Cape Canaveral on January 7, 1960. The Polaris program started development in 1956. The USS " George Washington ", the first US missile submarine, successfully launched the first Polaris missile from a submerged submarine on July 20, 1960. 北极星（POLARIS）是美国第一代潜射弹道核导弹，采用两级固体发动机，代号VGM-27，1957年研制，1960年装备，先后发展了A1/A2/A3三种型号，分别装备华盛顿级、伊桑艾伦级、拉菲特级核潜艇，现已退役。各型号性能：长8.69-9.8米，直径1.37米，射程2200-4600千米，起飞重量12.9-16.4吨，命中精度927-1850米，核弹头重339-500千克，当量60-80万吨。A3型采用3弹头，当量为20X3万吨。除美国外，还有64枚A3型供4艘英国核潜艇使用. 参考文献： https://www.usna.com/SSLPage.aspx?pid=659srcid=502%201946:1 Richard Moore.

五角大楼周二表示他们不知道是什么制造了北卡海岸上空的被猜想是导弹发射留下的尾状气柱， http://www.washingtonpost.com/wp-dyn/content/article/2010/11/09/AR2010110907033.html The Pentagon said Tuesday it did not know what created a vapor trail that crossed the skies off the Southern California coast and resembled a missile launch. http://www.cbsnews.com/stories/2010/11/09/national/main7036716.shtml 该链接可观看视频。 A mysterious missile launch off the southern California coast was caught by CBS affiliate KCBS's cameras Monday night, and officials are staying tight-lipped over the nature of the projectile. CBS station KFMB put in calls to the Navy and Air Force Monday night about the striking launch off the coast of Los Angeles, which was easily visible from the coast, but the military has said nothing about the launch. KFMB showed video of the apparent missile to former U.S. Ambassador to NATO Robert Ellsworth, who is also a former Deputy Secretary of Defense, to get his thoughts. Scroll down for KFMB video showing the launch . It's spectacular It takes people's breath away, said Ellsworth, calling the projectile, a big missile. Magnificent images were captured by the KCBS news helicopter in L.A. around sunset Monday evening. The location of the missile was about 35 miles out to sea, west of L.A. and north of Catalina Island. A Navy spokesperson told KFMB it wasn't their missile. He said there was no Navy activity reported in the area Monday evening. On Friday night, Vandenberg Air Force Base, in California, launched a Delta II rocket, carrying an Italian satellite into orbit, but a sergeant at the base told KFMB there had been no launches since then. Ellsworth urged American to wait for definitive answers to come from the military. When asked, however, what he thought it might be, the former ambassador said it could possibly have been a missile test timed as a demonstration of American military might as President Obama tours Asia. It could be a test-firing of an intercontinental ballistic missile from a submarine to demonstrate, mainly to Asia, that we can do that, speculated Ellsworth. Ellsworth said such tests were carried out in the Atlantic to demonstrate America's power to the Soviets, when there was a Soviet Union, but he doesn't believe an ICBM has previously been tested by the U.S. over the Pacific. Officially, at least, the projectile remains a mystery missile.
