''Cheng An'' (成安) is a ''Type D Escort Ship'' (丁型海防艦 ''Tei-gata Kaibōkan'') ''CD-40'' constructed at Fujinagata Shipyards in Osaka, Japan, and completed on December 12, 1944. ''CD-40'' survived the war and was ceded to China on August 29, 1947, being then renamed ''Cheng An'' and commissioned along with former ''CD-104'' and former ''CD-192'' after being judged as fit for immediate further service. ''Cheng An'' was decommissioned in 1963 | ''Cheng An'' (成安) is a ''Type D Escort Ship'' (丁型海防艦 ''Tei-gata Kaibōkan'') ''CD-40'' constructed at Fujinagata Shipyards in Osaka, Japan, and completed on December 12, 1944.

Unlike the late-war Matsu and Tachibana class destroyers, which are essentially a return to the "2nd-class destroyer" concept that fell out of favor as a result of post-WWI naval treaties with features conducive to escort operations, Kaibōkan type ships are wholly dedicated to coastal defense and ocean escort duties. | |

+ | Because of Japan's deteriorating war situation, the ''Type D'' class was a further simplification of the ''Ukuru'' (Modified ''Type B'') design and were built to the same design as the ''Type C'' escort ship. However, due to a shortage of diesel engines to power both groups of vessels, the ''Type D'' were powered by turbine engines. This gave a slight increase in speed, from 16.5 to 17.5 knots, but a reduction in range and endurance, 4500 miles at 14 knots instead of 6500 miles. The ''Type D'' was the only Kaibōkan type to use turbines. | |||
They were smaller by 200 tons than the ''Ukuru''’s and engines that propelled them were also smaller, at 2500 SHP vs 4200 for the ''Ukuru''s. Because of the decrease in engine power, the speed fell from 19.5 to 17.5 knots. The number of 4.7" guns went from three to two. The number of depth charges aboard was the same, 120, but the number of depth charge throwers was decreased from 18 to 12 and the depth charge chutes were decreased from two to one. | They were smaller by 200 tons than the ''Ukuru''’s and engines that propelled them were also smaller, at 2500 SHP vs 4200 for the ''Ukuru''s.

Chengan — Pan-Asian Tier I cruiser.
Taking advantage of a loophole in the London Naval Treaty that placed no restrictions on the number of ships with a displacement of up to 600 tons, Japan started building small ships in the 1930s that were classified as Kaibōkans—originally in Japan, this referred to obsolete ships repurposed for coastal defense needs. The project was developed by Mitsubishi. Kaibōkan No. 40 was built at the Fujinagata shipyard. After the surrender of Japan, the ship was used in the fleets of the Anti-Hitler coalition countries as a minesweeper, and in the August of 1947, she was transferred to the Chinese fleet and renamed Chengan. In 1949, the ship became part of the Republic of China Navy.
