Used mainly as a Test/Trials/Experimentation boat and later as a target boat. The experimental trials, carried out mainly in the Scottish lochs where depths and availability of submarine testing facilities was readily available, were related to improved electrical systems providing greater speeds, entailing many structural streamlining and electrical modifications that were carried out by the Navy at Portsmouth but with original overseeing by the original Builder.
Used as target practice in the 1960s, HMS Scotsman was eventually sunk in Kames Bay, off the Isle of Bute, then used for practice in salvage exercises by Clyde Lifting Craft. Finally raised in June 1964 for scrapping and despatched to the West of Scotland Shipbreaking Company in Troon.
