SS Cape Island (T-AKR-10)
SS Cape Island (AKR-10) was originally laid down for commercial service in 1976 as Illinois, a Type C7 ship for the States Lines. It was eventually transferred to the Naval Vessel Register (NVR)  as the USNS Mercury, as a transport ship for vehicles, and other goods. The ship was returned to Crowley Liner Services of Jacksonville, Florida. In 1993 the ship was permanently transferred to the navy's ready reserve force, and renamed Cape Island (T-AKR-10). The Cape Island remains laid up in a ready reserve state so that it may be activated in five days, if called upon. The ship is currently moored in Tacoma, Washington. As of 9/12/23, SS Cape Island is undergoing sea trials in the Strait of Juan de Fuca. Further reading
