Some errors
The first RN nuclear sub was the Dreadnought, which came into service with an US reactor in 1962. Two Valiant class SSN's followed, then four Resolution SSBN's, then three Churchill class SSN's (one of which was Conqueror) before the 7 Swiftsures and 7 Trafalgars (of which three are still in service).
