An item referred to the magazine Schiffbau dated 7 March 1928 reporting that the British submarine HMS Oberon (1) with a displacement of 1.345 (surfaced)-1.805 (submerged) tons was completed at Portsmouth, England and to be commissioned on short notice. Of this design were 12 boats being built or was the building approved. The Royal British Navy seemed to prefer this design above larger submarines for combat value, manoeuvrability and availableness. They were easier and with more reliability to handle as the so-called submarine cruisers which latter alone could serve on open sea and deeper waters and with a much too large diving time considered the demands of modern times.
Note.
1. First of the O class submarines, laid down at the Chatham Dockyard, England on 24 September 1924, launched on 24 September 1926, commissioned on 24 August 1927, decommissioned on 5 July 1844 and sold to be broken up on 24 August 1945. Pennant number P21
