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.
After a demonstration in 2001, Austal signed a three-year lease with Military Sealift Command for the WestPac Express.[1] [2] [3]
In March 2011, the WestPac Express was deployed as part of the US response to the 2011 Tōhoku earthquake and tsunami.[4] In recognition of this service, Admiral Mark Buzby presented the ship’s crew with United States Merchant Marine Outstanding Achievement Medal at a ceremony on board the ship in Yokohama, Japan.[5] The lease was renewed successively until the end of 2017.[6] [7]
In April 2016 WestPac Express was sold to Irish Continental Group, who continued to lease it to the Military Sealift Command until the end of 2017.[7] [8] [9]
With its charter to the US Navy completed, in January 2018 WestPac Express arrived in Belfast for refurbishment at Harland & Wolff to replace the Jonathan Swift on Irish Ferries' Dublin to Holyhead route.[10] [11] [12] It entered service in April 2018.[13] [14]
With a design based on the WestPac Express, Austal USA built 10 Spearhead-class expeditionary fast transport vessels for use by the United States Navy, the United States Marine Corps and the United States Coast Guard with a further two on order.[15] [16]
