Talk:Mitsubishi K3M

"The Mitsubishi K3M2 (九〇式機上作業練習機 Kyūrei-shiki kijō sagyō renshūki?) was a trainer built by Mitsubishi which was used widely in the Imperial Japanese Navy from World War I through the end of World War II" and "The prototype, designated Mitsubishi 4MS1, made its maiden flight in 1930.". How can a trainer which first made its maiden flight in 1930 have been used widely in the IJN since WW1? Hammerfrog (talk) 12:02, 5 April 2014 (UTC)
