Player Opinion

Performance

The start of the Pan-Asian tech tree, Chengan is best played at medium to long range. She is the smallest ship at her tier, and compensates for a lack of armor with agility and concealment. Her small size and fast rudder shift make her a difficult target to hit. When under fire, captains should use evasive maneuvers such as weaving and try to maintain 7 to 8 kilometers of distance between themselves and the enemy.

If Chengan finds herself in a close-range engagement, she will struggle to penetrate the citadel armor belt of Erie, Hashidate, and Hermelin. If this occurs, aim for the bow, stern, or superstructure to avoid non-penetrations. Despite her inability to hit the citadel of those ships, Chengan is capable of penetrating the citadel armor belt of Black Swan, Bougainville, and Orlan. If any of those three ships show their broadside, captains should aim for the waterline under the smoke stack to inflict severe damage. Captains should also utilize Chengan's excellent concealment to dictate the engagement. When fully specialized, Chengan will not be out spotted by any of the other Tier I ships. This stealthiness enables her to set up ambush-style attacks or disengage from a greater enemy force.

Pros:

Very small and agile (lowest turning circle radius and rudder shift time of all Tier I ships).
Excellent concealment (lowest detectability range of all Tier I ships).
Fastest turret rotation of all Tier I ships.
Small and therefore difficult to hit.

Cons:

Weak citadel armor belt.
Shortest main battery firing range of all Tier I ships.
Sluggish main battery reload time.
Slow top speed (slowest Tier I ship together with Black Swan and Bougainville).

Research

Availability of researchable upgrades for Chengan is as follows:

Main Battery: No available upgrades.
Hull: Progression to consecutive ship, Longjiang.
Gun Fire Control System: Type 1 Mod. 1 can be upgraded to Type 1 Mod. 2 for a 10% firing range increase.
Engine: No available upgrades.

Players wishing to progress further in the line should prioritize research and purchase of Longjiang. For players who enjoy playing Chengan, GFCS Type 1 Mod. 2 is an inexpensive upgrade to research and mount.

 ''CD-40'' was a Type D Escort Ship (丁型海防艦 ''Tei-gata Kaibōkan'') constructed at Fujinagata Shipyards in Osaka, Japan, and completed on 12 December 1944.  Her career with the Imperial Japanese Navy lasted barely a year, as she escorted convoys of war materiel and supplies throughout Japanese-held territory.  She had several run-ins with U.S. Navy submarines, including USS ''Balao'' and USS ''Tirante'', failing to defend her escorts on a few occasions.
-She was damaged by an aerial mine dropped by a B-29 "Superfortress" off Futaoi Island in the Sea of Japan on 13 April 1945 and was laid up for a month for repairs.  Following her return to active duty on 20 May, she saw no additional action or convoy duty for the remainder of the war.  She was struck from the list of the Imperial Japanese Navy on 30 November 1945 and assigned to minesweeping duties for the Allied Occupation Force.

 ''CD-40'' was ceded to China on 29 August 1947.  She was renamed ''Chengan'' (成安) and commissioned into the service of the Republic of China, along with former ''CD-104'' and former ''CD-192''.  ''Chengan'' was decommissioned in 1963.<ref name="Combined Fleet">[Bob Hackett, Sander Kingsepp and Peter Cundall. Imperial Japanese Navy Page. https://www.combinedfleet.com/CD-40_t.htm]</ref>
