The Momis were completed in 1919-22, mostly in Navy yards. They were ugly but seaworthy ships, with unusual placement for some of their weapons that reduced firing arcs but increased protection from bow waves. Many were converted to other uses by the time the war started; some as tenders and several as patrol boats. Most of the latter were equipped with Daihatsu landing craft to operate as fast transports, where the high bows provided some slight protection from incoming fire during landing operations.
