Dublin Swift is a high-speed catamaran built in 2001 by Austal as a passenger and vehicle catamaran ferry. After conversion to a Maritime Prepositioning ship the vessel was chartered by the United States Navy's Military Sealift Command until January 2018 as WestPac Express. It was then converted for civilian use as a passenger ferry by Irish Ferries and renamed Dublin Swift.
