Titan, better known by its former nickname Herman the German (US Navy designation YD-171), is a large floating crane currently serving in the Panama Canal Zone performing heavy lifts for lock maintenance. Prior to its move to Panama in 1996, the crane was based at the Long Beach Naval Shipyard (LBNSY) from the end of World War II until the closure of LBNSY in 1995. It was seized from the German Kriegsmarine following the end of World War II as part of war reparations. The crane was built by Demag Cranes AG as Schwimmkran nr. 1 in 1941 for the Kriegsmarine, where it had served in the Baltic Sea tending German U-boats.
The crane was one of four sister ships, two of which are still afloat and in service.
