联合王国自制核弹头,但根据一项长期协定使用美国制造的导弹。 The UK makes its own nuclear warheads but uses US-built missiles under a long-standing agreement.

联合王国在AWE Berkshire为三叉戟导弹系统生产自己的核弹头,同时根据1963年《北极销售协定》获得美国制造的三叉戟二型D5型导弹。 The UK produces its own nuclear warheads for the Trident missile system at AWE Berkshire, while acquiring US-built Trident II D5 missiles under the 1963 Polaris Sales Agreement. 这些导弹储存在格鲁吉亚金斯湾潜艇基地,并在装上联合王国潜艇之前加以维护。 The missiles are stored and maintained at Kings Bay Submarine Base in Georgia before being loaded onto UK submarines. 然后将弹头安装在苏格兰皇家海军基地克莱德。 Warheads are then fitted at HM Naval Base Clyde in Scotland. 联合王国的核威慑依靠这种伙伴关系,美国提供导弹维护和支持,尽管核弹头是独立开发和在联合王国生产的。 The UK’s nuclear deterrent relies on this partnership, with the US providing missile maintenance and support, though warheads are independently developed and produced in the UK.
