Project history

D class escorts became the unique purpose-built IJN escorts with a steam turbine machinery. Abandoning from diesels was a compulsory measure: their production lagged behind requirements of navy, therefore half of escorts of the programme 1943/1944 received turbines. These ships concerned to D class and received even numbers, unlike diesel-driven C, having odd. Differences intermeal concerned with the ships of both types only machinery, and in remaining they were absolutely identical. As main on D class turbines were used,  similar installed on standard transports of 2А class. Two such turbines through gear unit worked on the single shaft. Steam turbine propelling plant application has allowed to raise some speed, but has led to decrease in endurance almost on third. It is interesting, that because of oil shortage these ships began to convert to coal-burning from January, 1945, and by the war end they practically did not felt oil "hunger".

Under the programme 1943/1944 143 ships (CD2-286, only even) have been ordered, but in 1944 orders on 72 (CD86-100, only even (huls Nos2743-3750), 108 (2754), 110 (2755), 114 (2757), 120 (2760), 128 (2764), 136 (2768), 140 (2770), 146 (2773), 148 (2774), 152 (2776), 162-184 (only even, 2781-2792), 188 (2794), 206-286 (only even, 2803-2843) were cancelled. In March, 1945 building of being in low availability CD70, 80 and 122 was suspended.

By the moment of capitulation there were 5 ships in completion. Works on four of them (CD58, 78, 116 and 142) have completed in 1946. Fifth (CD62) scheduled to completion in January, 1946 foundered in Kure harbour because of a leak; subsequently she was raised and handed over on demolition in 1948.

Modernizations

early 1945, all survived earlier ships: + 6 x 1 - 25/60 96-shiki

mid-1945, most survived earlier ships: - 2 x 1 - 25/60; + 2 x 2 - 25/60 96-shiki
