Talk:Vityaz-D Autonomous Underwater Vehicle

I've significantly reduced the size of this article to remove apparent lack of neutral voice. I am not a Russian partisan -- I am a historian writing about deep submergence technology and this Vityaz-D is a significant step. In trying to correct the broken ref, I've screwed things up and don't know how to revert to the earlier version. GwyncannGwyncann (talk) 20:16, 10 September 2020 (UTC)
