The M-802 is a very large craft with relatively little armour for its size. Each of the 105 mm gun mounts are in a casemated shelter with 8 mm of anti-fragmentation armour. Both 37 mm FlaK C/36 mounts are protected by 8 mm hardened steel armoured gunshields, with the 20 mm mountings all having 12 mm hardened steel gun shields. Hull-wise, the M-802 is much more lacking, featuring 10 mm rolled homogeneous armoured plating only around the bridge and boiler-room.

The M-802 features a crew complement of 107 sailors, which allows the vessel to take a battering from normal munitions with relatively little issue, though fires and explosions will quickly cause crew to die. With its torpedo tubes, depth charges, and ammunition racks being entirely unarmoured, these fires and explosions can occur quickly aboard vessels with foolhardy commanders, leading to rapid sinking of the vessel due to hull breaches and crew loss. The guns, while susceptible to larger calibre munitions, will usually survive being targeted by PT boats, as their spacing across the ship makes them relatively difficult to completely disable.


Speedforward / back
AB46 / 16 km/h
RB31 / 11 km/h

Being a coal-fired vessel, the M-802 is relatively slow in its course. With a maximum speed of 31 km/h in a straight line, and 821 tonnes of displacement to contend with, the ship is not quick to accelerate or come to a stop. Its base rudder turning time of 5.4 seconds also leaves much to be desired in its turning, with course correction often involving 3 point turns compared to the PT boats it spawns near.

Primary armament

2 х Turret10.5 cm/45 SK C/32 cannon
Ammunition100 rounds
Vertical guidance-10° / 70°
Main article: SK C/32 (105 mm)

The M-802 is equipped with a primary armament of two 105 mm SK C/32 cannons. With 100 shells per gun for a grand total of 200 rounds aboard the ship, and access to 2 types of HE and a time-fuzed HE shell, they are effective anti-PT boat weapons. Fights against destroyers are also possible with these weapons, though care is needed to avoid their return fire.

With a four-second reload on such a large calibre munition, an 8°/s traverse rate, and access to high explosive with base fuse ammunition, hits to most non-destroyer vessels will cause massive damage, often times instantly destroying a compartment and occasionally knocking out PT boats with a single shot. Mounted fore and aft aboard the vessel, their firing angles are superb for all forms of engagement, and ballistic performance is par for the course for the 105 mm guns in-game.

Secondary armament

2 х Turret3.7 cm FlaK-Lafette C/36 mounting
Ammunition2000 rounds
Belt capacity5 rounds
Fire rate250 shots/min

The M-802's secondaries are its two 37 mm FlaK C/36 mounts, fore and aft on the superstructure. Mounted above and behind the main guns, one in front the bridge and one behind the funnel, with good firing arcs, these guns make quick work of PT boats and incoming aircraft at medium to close ranges. Letting the AI control them is usually sufficient for most situations, though manual control can be taken to dispatch pesky enemies getting too close for comfort with more speed than trying to rotate the main guns. Though access to mainly HE and mainly APT belts is available, the default Universal belt offers a good balance of the two shells and is the primary ammunition of choice for these guns.

Strung along the top of the bridge and tail-end of the superstructure, the M-802's anti-aircraft armament consists of 20 mm FlaK38 mounts. Featuring one Flakvierling above and amidships of the rear 105, and two double mounts atop the bridge, the 20 mm have full coverage of the ship, though all 3 cannot be brought to bear on any target but aircraft above the vessel. There are no customizable belts for these guns, though manual control of the Flakvierling will still remove all but armoured PT boats at any range below a kilometre nearly instantly. Against aircraft, the true effective range is under 2 km when controlled by the AI gunners.

Additional armament

Setup 12 x 533 mm G7a torpedo
Setup 24 x WBG depth charge
Setup 32 x 533 mm G7a torpedo
4 x WBG depth charge

Being a sub-chaser, the M-802 does have access to two 533 mm G7a torpedoes, though they are fixed in position in two deck-mounted tubes firing to either front side of the ship. With a maximum speed of 56 km/h in the water and a 14 km range, they are effective against destroyers and cruisers, and their 280 kg charge of SW39a deals a significant amount of damage on a hit.

The M-802 is also equipped with depth charges as a supplicant to its torpedo armament. 4 WBG depth charges with 100 kg of TNT apiece are mounted on launchers to either side of the rear 37 mm, with 2 firing to each side. Their high weight means they land relatively close to the vessel, meaning they are only effective at destroying torpedoes approaching amidships or PT boats making close runs against the side of the vessel.

Usage in battles

Being such a large vessel with a PT boat spawn, and at a relatively high BR for PTs, the M-802 makes itself a massive target for 40 mm gunfire from opposing vessels, which can quickly incapacitate the ship and detonate its ammunition stores. As such, playing the M-802 with a mind towards solid cover is an absolute must. Hiding behind island tips with the 105 mm guns exposed allows for protection of the ammunition and torpedo launchers, preventing easy kills for the enemy. Her strong secondary and anti-air armament means that planes are of relatively little threat, provided you keep an eye to the sky and engage them when spotted. The AA and secondary guns also allow for last minute countering of PT boats that managed to sneak up on you., which can happen quite often with the M-802's low speed. If possible, avoid bringing the torpedoes and depth charges into any serious matches, as though they can be useful in certain situations, their high likelihood of detonation leaves little point in the tradeoff outside Enduring Confrontation matches.

Pros and cons


  • Adequate armament including multiple 2 cm Flakvierlings and two hard-hitting 105 mm cannons
    • Highly-effective anti-aircraft suite that is ideal for closer ranges (below 2 km)
  • Multi-compartment design prevents quick sinking to small calibre fire
  • Good survivability for a ship of its size, with a large crew count
    • Engine compartment is protected by armour and coal bunkers, meaning that it is hard to knock out
  • Can carry torpedoes to deal with heavier targets which it cannot outgun
  • Coastal fleet spawn means can get into combat with smaller vessels faster than previous spawn location.


  • Survivability is compromised by the unarmoured hull and open gun mounts, which offer little protection
    • Crew complement is used up in relatively exposed positions
  • Incredibly slow, with a top speed of just 26 km/h in RB - this boat will take a while to get anywhere!
  • AA suite is composed of small-calibre weapons which are ineffective at longer ranges
  • Relatively small main armament (two guns) means the ship will be outgunned by most ships at its BR (including many destroyers)


The "M-802", really the Minensuchboot (Minesweeper) 1943, was a class of minesweeping sub-chaser developed by the German Navy as a simplified but enlarged version of the Minensuchboot 1940. Featuring a unique design of hull and improved firepower over its predecessor, the 1943 proved to be an effective vessel, with some remaining in service into the 1960s.

Designed around simplifying production, construction of the 1943 was not limited to shipyards entirely. The design of the vessel called for 8-10 pieces of hull that could be created in regular factories and transported by train to a shipyard, where final assembly would commence. From these pieces, the 7 segments of the boat would be constructed and finally fitted out. Due to this construction method, the 1943 only took an average of 8 weeks to completely construct, and was done so at a much cheaper cost. Final fitting out was completed in the Rostock and Koenigsberg shipyards exclusively. Of the 18 vessels built, all were coal-fired due to lack of oil for other types of boilers, though some were converted to oil firing postwar in their other roles.

Though some were sold to civilians postwar, to be used as ferries and trawlers, 1 was retained by the German Navy and received periodic upgrades before being scrapped. The remaining vessels went to the British and Americans as war plunder and were scrapped soon after.
