Thanks Bunnahabhain, I did indeed mean that.

Teribus, I assumed many on here might not understand if I used the terms SSBN, SSN, & SSK...hence I put the word 'conventional' in inverted commas. Maybe I should have explained it better.

I'm aware our last Diesel-Electrics ('Upholder' class, by name, yes?) were sold off, to Canada....I remember it being talked about on here.

Number 6/biLL...what happened to the subs I've just mentioned...were they scrapped?
