In the early 70s the Varsity Squadron of the Air Electronics and Air Engineer School had a inshore patrol war role. The main aim was to look for USSR Whiskey(?) Class submarines equipped with their equivalent of Regulus.(SSN 3?). These had to surface to launch the missiles, which it took about 15 mins to do. Our brief was, if we saw one surfaced, to prevent it from firing its missiles. Our sole armament was a Very Pistol. So, to prevent the missile launch, there was only one thing to do. Ram it!
