The No.19 class minesweeper (第十九号型掃海艇,, Dai Jūkyū Gō-gata Sōkaitei^?) was a class of minesweepers of the Imperial Japanese Navy (IJN), serving during the World War II. 70 vessels were plannned under the Maru 4 Programme (Ship # 164-169), Maru Kyū Programme (Ship # 410-437) and Kai-Maru 5 Programme (Ship # 5301-5336), however, only 17 vessels were completed.

Background

• Project number I4B. Improved model of the No.7-class. The IJN gave them a turret of 55 degrees gun elevation,^[1] because the IJN wanted to attack the strong point of behind the hill to them. And it was not useful in the Pacific War very much.
• And after the Maru Kyū Programme vessels abolished double-curvature bow for a mass production and changed bow shape.
