 The '''2 cm/65 Flakzwilling 38''' is a German WWII light naval twin anti-aircraft cannon mount found on many motor torpedo boats, minesweepers, destroyers, and cruisers in the German naval tech tree, either with or without a gunshield. The Flakzwilling 38 is a twin mount of [[2 cm/65 C/38 (20 mm)]]. A quadruple mount variant also exists, called [[2 cm/65 Flakvierling 38 (20 mm)]].

 Also keep in mind that, because of the rate of fire and amount of guns, Flakzwilling 38 can run out of ammunition on certain boats. It's always a good idea to practice conserving ammunition, even disabling the AI gunners if necessary. On larger ships though, this isn't much of an issue.

 The primary belt choice for this gun should be the 20 mm HET belt since it contains the highest HE:AP ratio. Several 20 APT belts should also be taken to deal with armoured targets, primarily USSR armoured river patrol boats. For destroyers and cruisers armed with Flakzwilling 38, if the option is available, only take 20 mm HET, since the main guns can handle any armoured targets much better.

 Development began in 1938 for a replacement for the Flak 30 an army version of the 2 cm/65 C/30 after issues arose in its slow rate of fire and small ammunition magazine size. Rheinmetall began production of the new gun, Flak 38, in 1939, with it entering service the same year. In 1940, a naval version, 2 cm/65 C/38, entered production and service in the Kriegsmarine, where it would replace the older 2 cm/65 C/30.
-The 2 cm/65 C/38 had the same dimensions as its predecessor, with a bore diameter of 20 mm and a barrel length of 1.300 m, while also managing to be 6.5 kg lighter at 57.7 kg total weight. Like the 2 cm/65 C/30, the gun was fully automatic and recoil-operated, and it fired the same ammunition: a HE round that weighed 0.134 kg and had a muzzle velocity of 835 m/s; and an AP round that weighed 0.148 kg and had a muzzle velocity of 800 m/s. The barrel was also of a monobloc design and could be easily removed and replaced. However, unlike its predecessor, 2 cm/65 C/38 was fed with 40-round magazines, as opposed to the 20-round magazines of the C/30, and had a cyclic rate of fire of 480 rounds per minute and an effective rate of fire of 220 rounds per minute, a noticeable improvement over the 280 rounds per minute cyclic and 120 rounds per minute effective of the C/30.

 Available for the gun were three mounts: L/30, L41, LM44U. L/30 was the standard single mount for the 2 cm/65 C/38. It weighed 416 kg with the gun and was manually operated, able to depress -11° and elevate +85°. At its base was a small ammunition storage for up to five magazines, which would be manually loaded by the crew into the left side of the gun. On the right side was a bag which would catch spent casings. L41 was a single mount designed for use in the comparatively confined spaces of S-Boote. It weighed 500 kg, could only depress to -10°, and traversed with the use of a hand crank. LM44U was a special twin mount which weighed 3,600 kg total and was designed to withstand up to 200 m depths for use on submarines. The mount could depress -10° and elevate +78°. It was driven by hydraulic devices and could train at a rate of 30°/s and could elevate at a rate of 30°/s or 60°/s, set by the operator who also fired the guns using two foot pedals, one for each gun.
