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. Subsequently on War programme of 1941/1942 62 more ships on slightly modified design (Ch28) were ordered: 34 ships from which entered service and remaining (Ch62, 64-89) were cancelled in 1943.

Modernizations: 1944, all earlier ships: + 1 x 3 - 25/60 96-shiki, 1 DCR

1944-1945, many earlier ships: + 2-shiki 2-go or 3-shiki 1-go radar
