> A live fire test of a nuclear torpedo prototype seems ... more than a little unlikely. What you have here is the description of a test just like any of the American tests: a bare warhead is detonated under certain conditions, with perhaps targets nearby to determine the effects. Meaning that the targets were 6.5 miles from the warhead. And no "launching submarine" was involved,

I was just going off what I quoted from wikipedia, which does specifically say that a submarine launched a T-5. Beyond that I can't speak to the accuracy of the wikipedia article.
