The LGM-118 Peacekeeper, originally known as the MX for "Missile, Experimental", was a MIRV-capable intercontinental ballistic missile (ICBM) produced and deployed by the United States from 1986 to 2005.

2020年10月20日 · The MX or Peacekeeper Intercontinental Ballistic Missile (ICBM) was the last type of ICBM deployed by the U.S. Air Force in the Twentieth Century. Several innovations made the Peacekeeper one of the most lethal nuclear weapons in history.

LGM-118弹道导弹（英文：LGM-118 Blastic Missile，绰号：Peacekeeper，译文：和平卫士；又称：Missile-eXperimental，译文：MX弹道导弹；亦曾称为：LGM-118A/MGM-118A弹道导弹，原名：先进洲际弹道导弹（AICBM）），是20世纪70年代美国研制的一型固体燃料洲际弹道导弹。

2024年4月23日 · The LGM-118 Peacekeeper (MX) was a solid-fueled intercontinental ballistic missile built by the United States designed to attack hardened military targets.

In 1979 the United States Air Force announced plans for a new intercontinental ballistic missile system that would be deployed on a circular railroad track so that more than 200 missiles could be moved into 4,600 shelters to be constructed along the track.

On Sept. 19, the United States retired the most powerful and, arguably, the most controversial ICBM in the U.S. arsenal, the MX, after nearly two decades of service. But the missile’s various components could see a return to duty as the Pentagon …

喷管是火箭发动机中最为复杂的机械结构件，MX的喷管由于需要整体摆动的同时，承受来自燃烧室的高温高压燃气和高速固体颗粒的冲刷，设计方也是各种豪华材料一起上，从收敛段的高强度高耐温的三向编织的T-300碳-碳，到酚醛-碳的内衬，再到扩散段外层的玻璃纤维环氧。

Peacekeeper missile, intercontinental ballistic missile that was part of the United States’ strategic nuclear arsenal from 1986 to 2005. The MX (for “missile experimental”) was the most-sophisticated ICBM fielded by the United States during the Cold War against the Soviet Union .

1972年4月，美国战略空军司令部正式宣布展开新一代ICBM的研制工程，工程代号“导弹-X”（Missile-X），简称即为MX导弹。 按照要求，这种新型的洲际弹道导弹应当具备摧毁敌方多个加固地面目标，且自身在核战条件下射前生存能力很强的基本指标。

The Peacekeeper served as the U.S. Air Force’s most powerful, accurate and technologically advanced Intercontinental Ballistic Missile (ICBM) deterrent from 1986 to 2005. Conceived to replace the Minuteman ICBMs, its development began in the early 1970s under the name “Missile, Experimental,” or MX.
