The article Martin Dunbar-Nasmith reports a remarkable incident in the life of D4 which should certainly be incorporated into this article. --BjKa (talk) 19:02, 22 July 2015 (UTC)Reply

First submarine with a deck gun?

edit

It seems that the German submarine SM_U-3_(Germany) commissioned in 1909 was the first submarine fitted with an (offensive?) deck gun, two years before HMS D4.--Mschiffler (talk) 20:36, 29 July 2019 (UTC)Reply
