Project history: First submarine chasers (Ch1, Ch3 and Ch4 classes) not quite satisfied Naval Staff: first of all insufficient seaworthiness and mediocre manoeuvrability were marked. In 1939 design of new chaser has been prepared. As a basis for it the same ChÇ and Ch4 have served, but at the expense of wider and shorter hull new ship differed by much better manoeuvrability and had very small tactical diameter. Bigger, in comparison with a prototype, draught has positively affected seaworthiness.
Under 4th Supplementary programme of 1939 and additional programme of 1940 15 chasers of Ch13 class have been built.
Modernizations: 1944, all survived: + 1 x 3 - 25/60 96-shiki, 1 DCR
1944-1945, some survived: + 2-shiki 2-go or 3-shiki 1-go radar
1945, some survived: - 93-shiki sonar; + 3-shiki sonar
Naval service: Ch25 and Ch27 were sunk 15.7.1942 off Kiska by US submarine Grunion. Ch13 was sunk 3.4.1943 SE off Shiriyasaki by US submarine Pickerel. Ch24 was sunk 17.2.1944 by gunfire of US destroyer Burns W off Truk. Ch22 was sunk off New Ireland 19.2.1944 by US aircraft. Ch16 was sunk 4.7.1944 at Bonin by US carrier aircraft (TF.38). Ch18 was sunk off Luzon by US aircraft 30.12.1944. Ch17 was sunk 28.4.1945 off Fukushima by US submarine Springer. Ch14 was sunk 28.7.1945 at Owase by US carrier aircraft of TF.38. Ch26 was sunk 30.7.1945 in Korea Strait by US aircraft of TF.38. Ch19, 20 and 23 were captured in damaged condition, Ch23 was unserviceable.
