This paper ship is a japanese combat support ship AOE Mashu Class, created by Ministry of Defense Kids Site. The AOE Mashu class is an enlarged, improved version of the AOE Towada class. Its distinctive feature is the vastly improved replenishment capability, with size almost doubled over the previous replenishment ship design. Mashu was launched February 5, 2003 and commissioned on March 15, 2004. A sistership Omi AOE-426 followed one year later, laid down February 7, 2003, launched February 19, 2004 and commissioned on March 3, 2005.
The ships displace 13,500-tons standard and far more full load. They are said to have a vastly improved replenishment capacity over the previous Towada class. With an overall length of 221 meters (719-feet) and a beam of 27 meters (88-feet), the Mashu and Omi are undoubtedly large ships. The main engines are two Kawasaki Rolls Royce Spey SM1C gas turbines, providing 40,000shp for the two shafts for a top speed of 24-knots. The much larger size also allowed the Mashu to have not only a flight deck but also a hangar for her own organic aircraft.
