Small world Carlzere! Yeah, she's still in service as Tipoo Sultan. I didn't see her again in RN service after I left on return from the Falklands in 1982, but I know that Hugo's modification with the guns aft stayed in place on all 21s. My last frigate was Amazon and we had 20mms either side of the hanger as well as the ones up by the bridge. The hulls had all be reinforced as well because Avenger split port, stbd and midships due to the awful weather and enourmous seas around the Falkland Islands. We came very, very close to breaking in two and sinking! We were literally held together by railway type steel beams welded acrosss the splits and by some welded metal patches!
As for the Phantom killing one of her crew, that is true. My old RS in my training days at HMS Mercury had been a Leading Radio Operator on that trip when it happened. I believe that was the trip where a Russian destroyer cut across the bows of the Ark and ended up getting rammed. Another one my dad told me of (he was RN as well and was working at Rosyth on HMS Zulu at the time), which he got from a FAA CPO mate of his, was of a Phantom based at, I think, Leuchars. It was getting ready for a sortie when it shot off a Sidewinder by itself. The missile shot away over the airfield and disappeared into the distance, ending up hitting the end of one of the railway platforms at Leuchars station, some 2 or 3 miles away! Luckily enough the platform was empty and nobody was hurt, but everyone concerned was asked to keep it under their hats! Good story I always thought, even if it didn't actually happen!
