ABSTRACT

The Nuclear Notebook is researched and written by Hans M. Kristensen, director of the Nuclear Information Project with the Federation of American Scientists, and Matt Korda, a research associate with the project. The Nuclear Notebook column has been published in the Bulletin of the Atomic Scientists since 1987. This issue examines the status of the US nuclear arsenal. The US nuclear arsenal remained roughly unchanged in the last year, with the Defense Department maintaining an estimated stockpile of approximately 3,800 warheads. Of these, only 1,800 warheads are deployed, while approximately 2,000 are held in reserve. Additionally, approximately 1,750 retired warheads are awaiting dismantlement, giving a total inventory of approximately 5,550 nuclear warheads. Of the approximately 1,800 warheads that are deployed, 400 are on land-based intercontinental ballistic missiles, roughly 1,000 are on submarine-launched ballistic missiles, 300 are at bomber bases in the United States, and 100 tactical bombs are at European bases.

摘要

核笔记本由美国科学家联合会核信息项目主任汉斯·克里斯滕森（Hans M. Kristensen）和该项目的研究助理马特·科达（Matt Korda）研究和编写。《核笔记本》专栏已发表在《原子科学家公报》上自1987年以来。此问题研究了美国核武库的状况。去年，美国核武库大致保持不变，国防部估计库存约3,800枚弹头。其中只有1800枚弹头被部署，而大约2,000枚被保留。此外，大约有1,750枚退役的弹头正在等待拆除，总库存量约为5,550枚核弹头。在部署的大约1800枚弹头中，有400枚是陆基洲际弹道导弹，大约1000枚是海底发射弹道导弹，300枚在美国的轰炸机基地，100枚战术炸弹在欧洲的基地。
