SS Indigirka

The SS Indigirka (Russian: «Индиги́рка», IPA: [ɪnʲdʲɪˈɡʲirkə]) was an American built steamship that served in the Soviet Gulag system and transported prisoners. Launched in 1919 as SS Lake Galva, it served under the names Ripon, Malsah and Commercial Quaker between 1920 and 1938, when it was renamed Indigirka. On its final voyage in 1939 over 700 prisoners perished.

Pre-Soviet career

The ship was built at the Manitowoc Shipbuilding Company in Manitowoc, Wisconsin as one of the Lake series cargo ships. It was launched on 29 December 1919 as Lake Galva and completed in May 1920 as Ripon. It served as an American merchant ship under various owners as SS Ripon (1920–26), SS Malsah (1926–28), and SS Commercial Quaker (1928–38). In 1938 it was sold to the government of the Soviet Union.

Prison ship of the Dalstroi

With some modifications the ship was placed in service by the Dalstroi as the Indigirka (Индиги́рка) – named after the river in Siberia – for the transport of prisoners. With a tonnage of 2,689 and a length 77.3 m it was the smallest ship of the Dalstroi fleet and had a cargo hold of 4,700 m³; Bollinger estimated that it could hold 1,500 captives, while Tzouliades indicates that up to 5,000 prisoners might have been transported. That seems to conflict with evidence that the ship was fully loaded when it departed on its final journey with less than 1,500 crew, passengers and prisoners, forcing Soviet authorities to leave behind many others who were supposed to have made the trip.
