The Type D escort vessels were a response to the shortage of diesel engines for Type C escorts. They substituted coal-burning turbine engines for diesel, which gave them slightly greater speed but diminished endurance. They were constructed simultaneously with the Type C units. A total of 143 units were ordered, of which 62 were completed before the surrender.

Units were numbered CD-2 through CD-204 using even numbers only. Odd numbers were assigned to the Type C escorts.
