Contramaestre Casado

The Contramaestre Casado (A-01) is an auxiliary transport ship operated by the Spanish Navy. It primarily serves as a logistical support vessel, transporting military personnel, vehicles, and equipment between Spanish ports and overseas territories. The ship is one of the oldest active vessels in the Spanish fleet.

Originally built in Sweden in 1953 as the merchant vessel Thule, the ship was later renamed Leana. In 1982, it was intercepted and seized by Spanish authorities for contraband smuggling, after which it was acquired by the Spanish Navy and commissioned in 1983. Throughout its long military career, it has provided vital logistical transport, though it is currently nearing the end of its operational life.
