 Transmarine is formed by the Submarine Boat Corporation. The Submarine Boat Corporation is the former Electric Boat Company.
 NRT is a ship's cargo volume capacity expressed in "register tons", one of which equals to a volume of 100 cubic feet (2.83 m3). It is calculated by reducing non-revenue-earning spaces i.e. spaces not available for carrying cargo, for example engine rooms, fuel tanks and crew quarters, from the ship's gross register tonnage (GRT). Net register tonnage (NRT) is not a measure of the weight of the ship or its cargo, and should not be confused with terms such as deadweight tonnage or displacement.
 By then, she was fitted with one 8cm short barrel deck gun, two single 25mm machine guns and two depth charges.
Thanks go to Gengoro S. Toda of Japan.
