The '''''Hydra'' class''' were two [[minelayer]]s of the [[Royal Netherlands Navy]], built to serve in the [[Dutch East Indies]] and Dutch territorial waters in Europe. The construction of the ships began in 1910 and was completed in 1912. The ships were built by the navy yard (''Rijkswerf'') in [[Amsterdam]].  Both ships were still in service during the [[World War II|Second World War]]. Only ''Medusa'' escaped to the United Kingdom, however. ''Hydra'' was lost after the ship was fired on by an anti-tank weapon. The minelayer sank in the waters off [[Zeeland]].
