UK nuclear sub

Royal Navy Dreadnought SSBN program

We’ve published several commentaries in recent issues of CNR about the Royal Navy and the United Kingdom’s nuclear deterrent. In particular the commentaries have discussed how it is important to remember the conventional elements that are necessary for deterrence. But there is concern that the RN capability (and capacity) is eroding. Thus, it is interesting to read a new British parliamentary briefing entitled “Replacing the UK’s Strategic Nuclear Deterrent: Progress of the Dreadnought Class.” This report discusses the plan to maintain the British nuclear deterrent, via ballistic missile submarines. The Dreadnought program “is about the design, development and manufacture of four new Dreadnought class ballistic missile submarines (SSBN) that will maintain the UK’s nuclear posture of Continuous At Sea Deterrence (CASD).” Interesting reading.
