The SeaMaster was a fascinating machine. Ask even a well informed online forum to name two 1950s nuclear bombers designed for low-level operations and the answer will be "Valiant B.2 and .... errrmmm?".
There's quite a lot out there about the tech, but not so much on operational plans. What were they going to do, lurk in a fjord in Iceland and mine the
out of Murmansk?
