Does a programme already exist to replace the Royal Navy's Trident missiles?
Short answerNo separate missile successor is envisaged here. Continued Trident use is linked to the cost of an alternative and existing shared support arrangements.
NotesA separate British successor to the Trident missile is not envisaged in this discussion. Continued use of Trident is linked to the expense of developing an alternative. Britain shares elements of nuclear-warhead maintenance work with France and missile procurement through a common pool with the United States. These arrangements are presented as ways to share costs, with replacing them expected to require substantial spending.
