The Russian submarine AG-11 was an AG-class submarine, designed by the American Holland Torpedo Boat Company/Electric Boat Company, built for the Imperial Russian Navy during World War I. The submarine was fabricated in Canada, shipped to Russia and reassembled for service with the Baltic Fleet.

Description

AG-11 was a single-hulled submarine, with a pressure hull divided into five watertight compartments. The submarine had a length of 150 feet 3 inches (45.8 m) overall, a beam of 16 feet (4.9 m) and a draft of 12 feet 6 inches (3.8 m). She displaced 355 long tons (361 t) on the surface and 433 long tons (440 t) submerged. The AG-class submarines had a diving depth of 164 feet (50.0 m) and a crew of 30 officers and enlisted men.^[1]

The submarine had two 3-bladed propellers, each of which was driven by a 480-horsepower (360 kW) diesel engine as well as a 640-horsepower (477 kW) electric motors. This arrangement gave AG-22 a maximum speed of 13 knots (24 km/h; 15 mph) while surfaced and 10.5 knots (19.4 km/h; 12.1 mph) submerged. She had a range of 1,750 nmi (3,240 km; 2,010 mi) at 7 knots (13 km/h; 8.1 mph) while on the surface and 25 nmi (46 km; 29 mi) at 3 kn (5.6 km/h; 3.5 mph) while submerged.^[2] Her fuel capacity was 16.5 long tons (16.8 t) of fuel oil.^[3]

The AG-class submarines were equipped with four 18-inch (457 mm) torpedo tubes in the bow and carried eight torpedoes. For surface combat they had one 47-millimeter (1.9 in) deck gun.^[2]

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 (AG in Russian for Amerikansky Golland (American Holland)). The submarines were to be built in Canada as knock-down kits for assembly in Russia.^[2]

Components for the first batch of five submarines were assembled in 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 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 on 3 April 1918 just prior to the German landing there.^[4]
