Additionally, while she has been retired from service, the "Circle Line X" is retained by Circle Line. "Circle Line X" was originally built for the US Navy in 1944 as a Landing Craft Infantry (Large), designated USS "LCI(L)-758". "758" participated in several landings during the Pacific Theater of World War II, including those during the battles of Leyte, Ormoc Bay, Mindoro, and Lingayen Gulf. "758" was decommissioned in 1946 and sold to Circle Line, who converted her into a tourist vessel and renamed her "Circle Line X". She served in this role until her retirement in 2007, and as of 2015 Circle Line plans to turn her into a floating museum and terminal alongside Pier 83.
