Ship project history: First Japanese purpose-built submarine chasers: two chasers of Ch1 class provided by 1st Supplementary program of 1931. As well as majority of Japanese ships, designed in the early thirties, they suffered redundant upper weight. After incident with Tomozuru ballast was laid and hull longitudinal strength was increased. Ss a result displacement was increased from 266 to 376t, and speed was decreased from 24 to 21kts.

 

Modernizations: 1935, both: solid ballast was added, hull was strengthened, displacement was 376 / 400 t, speed was decreased to 21 kts.

1944, both: - 2 x 1 - 7.7/80; + 2 x 3 - 25/60 96-shiki, 2 DCT (36 DC at all)

 

Naval service: Ch2 was sunk 27/6/1945 by American submarine Blueback N off Lombok. Ch1 was beached 14/11/1944 at Sablayan, Mindoro after American air attack but later salvaged and repaired.
