Might as well be Carry On Watch My Stern, love 'em or hate 'em, these style comedies are national treasures. I seem to recall liking this one.
Amusing trifle about the trials of a new torpedo that has a tendency to sink friendly ships. Connor carries the film, which is slightly hampered by the typical stereotypes of the time.
There is one scene where Connor spouts a litany of techno-babble (in a Scots accent, no less!) and the Admiral replies "Dammit man, I'm a sailor, not a farmer." That little bit of prescient comedy is enough to give any Trekkie pause!
