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’s column examines the United Kingdom’s nuclear arsenal, which includes a stockpile of approximately 225 warheads. Of these, up to 120 are operationally available for deployment on four ballistic missile submarines. In 2021, however, the government announced the UK would increase its stockpile ceiling to up to 260 warheads.

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。自1987年以来，《核笔记本》专栏已发表在《原子科学家公报》上。本期专栏研究了英国的核武库，其中包括大约225枚弹头的储存。其中，多达120枚可用于4枚弹道导弹潜艇的作战部署。然而，在2021年，政府宣布英国将其库存上限提高至260个弹头。要查看以前的所有《核笔记本》专栏，请访问https://thebulletin.org/nuclear-risk/nuclear-weapons/nuclear-notebook/。
