RFA Sea Centurion was a fast sealift ship chartered to Britain's Royal Fleet Auxiliary between 1998 and 2002 and subsequently in commercial service with Stena on Mediterranean routes as M/S Ark Forwarder.

[1] Sea Centurion/Ark Forwarder is the lead ship of what was planned as a class of five vehicle carriers of 21,104 gross tons, although only three were built due to financial problems at the shipyard.

[2] Prolonged delays led to the Turkish operator UND walking away from the first ship,[2] the Stena Ausonia, which was delivered to the British in October 1998[1] as the Sea Centurion.

Then SEC entered bankruptcy with the second ship, Sea Chieftain, 50% complete and the third, Transmed's Aronte had been launched.

As of 2014[update] she is serving the Genoa-Palermo route for Stena under a Cypriot flag, homeported in Limassol.
