Anyone on here remember 'Grampus' being hit by one of it's own Torpedo's. It was 1974 if memory serves when a Mk44 went haywire and returned striking a direct hit on the attack scope which was bent over at right angles as a result. A quick return to Pompey was the order of the day as it was when the same Sub hit a Starboard navigation buoy off the Isle of Wight when the Jimmy had a go at navigating. The buoy cable became stuck in the foreplanes causing the buoy to end up stuck at the front of the boat. A right funny sight that was and a Courts Martial too!
