One of the best-known individual Schnellboots, the S-204 Lang, painted with a characteristic black panther, was originally built in the German Lürssen shipyard. Through most of its career, it operated from the Netherlands and the port of Kiel. It never got into direct combat against any Allied vessels, being used primarily as a patrol vessel. It became an icon when photos of its arrival under the white flag to the British naval base became public. In 1946, the S-204 was gifted to the USSR as a part of war reparations and eventually was broken up in the 1950s. The vessel can be found on covers of books, in model kits, and playable in War Thunder!

The S-100-class, S204 Lang was one of the earliest pre-orders offered to access the fleet closed beta test. It was introduced into the game and removed from the store with the wide-release of the closed beta test in Update 1.79 "Project X", and hasn't returned for sale since. She's a very fast, but also fragile vessel, which is best used for capturing the points and harassing enemy vessels, rather than engaging in short-range duels. Both her torpedoes and mines are excellent, making it possible to use her even in high BR matches with destroyers, but the overall large size makes her an easier target than more widely used torpedo boats. One should be especially cautious of fully exposing her sides, as she makes for a large, easy target with a relatively low crew count to resist even enemy machine guns.

Unlike most low-BR vessels, Schnellboots have an armoured bridge, with 13 mm hardened steel sloped between 22 and 76°, which makes it relatively rare to lose control over the vessel. While this, combined with a relatively large size, might make the vessel appear to be very survivable, in reality it's a fragile vessel. A low crew count, few internal compartments, wooden hull, and the necessity to expose its sides to deliver the bulk of the firepower, make it an easy target to destroy.

The best survivability can be achieved by moving directly towards or away from the enemy, where a single compartment is exposed to the enemy fire. The second-best option is to approach the enemy at an angle, where the exposed silhouette remains relatively small.

With the purchase of S-204 Lang one receives three decals: Lang and Panther, visible on the superstructure, and Star above "TA" placed on the aft of the vessel.

With a top speed of 109 km/h, the S-204 can beat even the hydrofoils in a straight line. It's one of the fastest naval vessels in the game, making it perfect for capturing the points and relocating to more comfortable locations when dealing with a bluewater vessels. For its large size, the vessel remains relatively manoeuvrable, being able to even dodge incoming high-calibre projectiles. That being said, its large size also impacts the turning circle, making it easier to crash into islands or other surface obstacles while manoeuvring in narrow areas of the map designed for smaller coastal vessels.

Much like all of the premium vessels, S-204 comes with all modifications unlocked and installed. But given the engagement ranges it typically fights it, it might be best to uninstall the Torpedo Mode modification, in order to trade shorter range for a much higher speed of the G7a torpedoes.

The main weapons of the S-204 are the three 20 mm cannons. A single-mount on the bow, and a twin-mount in the mid-section of the vessel. The bow-mounted 20 mm is the only gun on the vessel able to shoot at surface targets directly ahead.

In terms of the ammunition choice, the Universal or APT magazines are recommended against surface targets, while HET magazines are best used against aerial targets.

APT magazines have an advantage in being able to pierce through the ship, oftentimes entering through the bow and exiting through the rear of a small torpedo boats. These are best used against ships approaching directly frontally (e.g. in an attempt to bow tank).

HET magazines are highly advantageous against aerial targets, there they'll do the highest amount of damage per the round hit, while also offering the best chance of igniting the fuel tanks. Alternatively, they can be used against a particularly small boats, such as LS 3 or G-5.

Aft of the vessel is a 37 mm secondary gun. Unlike on the regular S-100, the gun shield here is much larger, offering added protection against the enemy gunfire. It can engage enemy aircraft at a very formidable range and offers a good damage output against the coastal vessels.

The AP ammunition can penetrate through any vessel it would meet, allowing to damage internal components, but it's at the price of much more limited damage. Purely in terms of the destructive potential against naval targets, the Universal belt seems to offer the shortest time to kill, offering a chance to put the enemy on fire, destroy components on the surface, and put armour-piercing rounds into the deep interior of the enemy.

Against aerial targets, the HE clips are the best, as they will instantly shred the structure of the enemy aircraft, while APT clips require you to directly hit critical components in order to score a kill against an aircraft.

Anti-aircraft armament

2 х Turret7.92 mm MG15 machine gun
Ammunition1500 rounds
Belt capacity75 rounds
Fire rate1000 shots/min
Both 7.92 mm MG 15 are located on the bridge, protected by a slope of 12 mm armor
Main article: MG 15 (7.92 mm)

The anti-air armament is mounted on the bridge, with an extremely narrow field of fire - only only ±16° horizontally and -1°/+40° vertically. The weapon itself is only a single 7.92 mm on each flank, being more symbolic than anything else when it comes to the damage output. This is furthered by the fact that one has to expose the entire side of the vessel to aim at the enemy, which is best avoided as it makes the large silhouette of the S-204 a very easy target.

Main articles: G7a (533 mm), EMF mine

The G7a torpedoes are excellent for such a low-BR torpedo boat. With an explosive filler equivalent to nearly 360 kg TNT, it's large enough to break through any torpedo bulge. Damage itself is sometimes enough to kill even a heavy cruiser with a single hit, but it will at least cripple any destroyer or a smaller vessel. It's recommended to uninstall the torpedo mode - in most maps there's little need to engage enemy vessels at over 6 km range, and having 45% higher speed makes a huge difference in accurately delivering a torpedo on the target.

The mines carried are also extremely dangerous, carrying explosive mass second only to the UDM-E. Realistically, the biggest limitation of the vessel in minelaying department is the number of mines carried - with just four available, one struggles to put down anything but a symbolic mine defense around capture points or critical locations. Scoring a kill with the mines is more luck than skill, but there's little disadvantage to taking them onboard, as the mines are unlikely to explode under the gunfire before the crew of the S-204 dies anyway.

Usage in battles

The S-204 Lang can be used exactly the same as its tech-tree equivalent: S-100. Making a use of all your firepower requires you to expose an entire broadside - if an enemy sprays your entire broadside, you'll most likely die right away. This creates an interesting play style, where one has to either approach or depart from the enemy at a sufficient angle to make use of at least two of your guns, while preferably avoiding being fired upon, and thus - playing on the outskirts of the main engagements. Its excellent top-speed is a huge enabler in playing such a harassing role.

Much like other fast boats, it finds a great use in contesting the capture points and flanking the enemies. On larger maps it might be beneficial to go for a more distant capture points, often these dedicated to the bluewater vessels, as the S-204 will likely be the first vessel to arrive at the location, long before lumbering destroyers get close enough to kill you and prevent capture.

Gameplay in the S-204 hugely benefits from regularly checking the minimap and relocating, rather than rushing towards the nearest targets, as a number of gunboats can easily outgun you in a duel.

Pros and cons

3.7 cm FlaK-Lafette C/36 features an extended gun shield on the S-204, compared to the regular S-100.


  • Broadside firepower
  • Very good torpedoes with a reload available
  • Ability to carry both: Mines and torpedoes at the same time


  • Below average survivability
  • In most of the frontal arcs, only a single 20mm gun is able to engage the enemy
  • Large profile makes an easy target for bomber and cannon-equipped fighters alike.
  • Anti-aircraft 7.92 mm MG 15 has an extremely limited field of fire (only ±16° horizontally and -1°/+40° vertically) making it unable to engage anything but enemy planes in a very shallow dive perpendicularly towards the vessel.


S 204 arriving under the white flag at Felixstowe

S-204 was built in the Lürssen shipyard in Vegesack, commissioned on 19 August 1944 to 4. Schnellboot-Flottille in the Netherlands. In the records from July 1944 the S-204 was under the command of OLt..z.S. Hans-Jürgen Seeger, nicknamed HaJü after its commander. On 10 October 1944 flottila was rebased to Kiel, on Baltic Sea. Once the Battle of the Bulge has begun, the 4th Schnellboot Flotilla was ordered back to the western front, where it arrived on 28 December 1944. In April 1945 the vessel was nicknamed Lang, under the command of Lt.z.S. Claus Hinrichs.

Following the 8th of May 1945 surrender, the S-204 was captured by the British forces in Rotterdam and carried the chief of the 4th Schnellboot Flotilla, KKpt Kurt Fimmen, along with KptLt Bernd Rebensburg to the British Navy base Beehive in Felixstowe. Claus Hinrichs remained the commander of the vessel, and the S-204 arrived at the British base under the white flag (see: picture right).

The vessel was delivered to the USSR on 4 January 1946 and assigned a new designation TK-1020. The following fate of the boat varies depending on the source.

  • According to the Schnellboots Attack, the vessel was reclassified from TK-1020 to reconnaissance boat РК-1674 on 17 June 1952, then reclassified to the dispatch boat ПОК-47 and finally decomissioned on 21 December 1954 to be broken up (decomissioning date also confirmed by the Warships of the Soviet Fleets).
  • According to Senotrusov Vyacheslav, TK-1020 was assigned to the Baltic Fleet on 7 February 1946 (days before Baltic Fleet was split into 4th and 8th Fleets of the USSR) and after a little bit over 2 years in service, she was mothballed on 28 February 1948. Following that, she was removed from mothballing on 12 January 1949 and transferred for breaking up on 25 September 1950 to the ОФИ.

A historical fiction book Armada, by Steven Wilson (published by Pinnacle Books), tells a story of the fictional loader for the 2 cm/65 C/38 named Matrose Willy Hellwig in the Chapter 11 of the book.

The vessel is also known from the 1:72 scale model of the S-100 sold by Revell.
