Japanese netlayer Fukuei Maru No. 15 (1939)

The Fukuei Maru No. 15 was a Japanese netlayer that entered service in 1939. Netlayers, also sometimes referred to as net tenders, were specialized vessels designed to deploy and maintain anti-submarine nets, mine nets, and other underwater barriers. They were primarily used for harbor defense, protecting strategic locations from enemy submarines and surface vessels.

Information regarding the Fukuei Maru No. 15's specific operational history, including its activities during World War II and its eventual fate (whether it was sunk, scrapped, or otherwise decommissioned) is currently limited and requires further research to fully document. Its construction and role are consistent with known practices of the Imperial Japanese Navy in constructing and deploying net defenses around key naval bases and ports. Further details would likely be found in Japanese naval archives and records, if available.
