    YFP-1 88k SS Jacona fitting out, 25 January 1919, at Todd Dry Dock and Construction Co., Tacoma, WA. This ship had the unusual fate of being converted to a non-self propelled power plant at Newport News in 1930. After serving in Maine and New Hampshire she became an Army ship in 1945 and the Navy's YFP-1 in 1947. She was reportedly still in excellent condition when transferred from the Navy to the Philippines in 1971.
