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 ChЗ 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.
