Description
''AG-12'' was a single-hulled submarine, with a pressure hull divided into five watertight compartments. The submarine had a length of length overall, overall, a beam (nautical), beam of and a draft (ship), draft of . She displacement (ship), displaced on the surface and submerged. The AG-class submarines had a diving depth of and a crew of 30 officers and enlisted men. The submarine had two 3-bladed propellers, each of which was driven by a diesel engine as well as a electric motors. This arrangement gave ''AG-22'' a maximum speed of while surfaced and submerged. She had a range of at while on the surface and at while submerged.Polmar & Noot, p. 240 Her fuel capacity was of fuel oil. The AG-class submarines were equipped with four torpedo tubes in the bow and carried eight torpedoes. For surface combat they had one deck gun.Construction and service
The Holland 602 design was widely exported during World War I and the Imperial Russian Navy ordered a total of 17, in three batches, of a version known as the American Holland-class submarine, ''American Holland''-class (AG in Russian for ''Amerikansky Golland'' (American Holland)). The submarines were to be built in Canada as knock-down kits for assembly in Russia. Components for the first batch of five submarines were assembled in Barnet, British Columbia, Barnet, near Vancouver, Canada, and shipped to Vladivostok. There they were loaded onto the Trans-Siberian Railroad and transported to Saint Petersburg where they were assembled by the Baltic Works by June 1916. During World War I Russian and British submarine flotilla in the Baltic, British submarines operated from bases in Finland. The Russian submarines of ''Holland'' type (''AG-11'', ''AG-12'', ''AG-15'' and ''AG-16'') were scuttled in the harbor of Hanko, Finland, Hanko on 3 April 1918 just prior to the German landing there.Polmar & Noot, pp. 239–40 ''AG-12'' and Finnish submarine AG-16, ''AG-16'' seemed to be in relatively good shape and the Finns decided to salvage them. The submarine was transferred to Vulcan (Turku shipyard), Ab Vulcan shipyard in Turku for repairs, although it proved to be hopeless, and she was soon scrapped.Notes
