Tragically topical: my book, 'On Her Majesty's Nuclear Service', which is about to be published (Feb 2018) describes in some detail the multiple hazards faced by submariners without even going to war. When the Argentine Navy announced that their submarine, San Juan, was missing, my publishers (Casemate (UK)), a specialist military history publisher, asked me to write a 500 word article on what might have gone wrong. Here is the link to that article. (I've also posted a version of it in the Navy section).
I have added some further information on the sinking in the Navy section of this wesbite.
