The R-301 is constructed using wood, the superstructure is hardened wood constructed to a thickness of 12 mm. The wooden construction of the R-301 means fire is one of the biggest threats to survival of the ship. There is no armour on the ship, apart from the gun shields and hardened superstructure. The R-301 has a crew complement of 42, increased by 1 compared to the R-130. The R-301 still provides a great attachment of sailors, which helps to increase the overall survivability of the R-301 dramatically compared to other ships in this tier.

Compared to the previous version R-130 which only offered two single 2 cm/65 C/30 (20 mm) automatic cannons and a single 3.7 cm FlaK-Lafette C/36 (37 mm) automatic cannon. This is now significantly increased even more with two twin 2 cm/65 C/38 (20 mm) automatic cannons, replacing the two single 2 cm/65 C/30 automatic cannons with twice as much stopping power and 200 round magazines for them. Additionally, the legendary single 3.7 cm FlaK-Lafette C/36 automatic cannon stays the same, the depth charge racks are replaced with two torpedo tubes are added.

However, the internal components of the R-301 are spaced out, meaning a good volley of enemy fire will not completely incapacitate the ship.

• The engine is placed, under the conning tower of the ship, with the transmission extending towards the stern (Rear) to the Voith Schneider propulsion system.
• The transmission & propeller systems are under the waterline, which protects it from most enemy rounds, which would penetrate the ship.
• The engine's system can be destroyed by enemy fire since it extends above the waterline.
• The ship's fuel and ammunition storage can be penetrated by enemy fire, since these are located above the waterline.

Mobility

Speedforward / back

AB60 / 23 km/h

RB43 / 16 km/h

The R-301 may seem slow in comparison to the other naval ships at this tier, due to its length. The Voith Schneider propulsion system, as found on the R-41 & R-130 has been replaced with a conventional three bladed propeller and transmission system. The engines have been increased from two to three.

The top speed has been increased by the change of propulsion system:

• In arcade, it has a maximum speed of 57 km/h.
• In realistic & simulator is 43 km/h.

However, the change from the Voith Schneider to the conventional blades has had a significant change on the manoeuvrability of this ship. It is incapable of performing the once fine manoeuvrable dance acts of the previous Voith Schneider propulsion system, which powered the R-41 & R-130.

The R-301's main armament consists of five 2 cm FlaK 38 automatic cannons. One dual mount in front of the bridge protected by a 8 mm hardened armour shield, one single mount directly behind bridge with no crew protection and one dual mount amidship between torpedo tubes, protected by the same shield as the other dual mounts. Due to the railing around the ship and the gunshields protecting the guns, they are unable to shoot directly in front of the ship up to about 400 m away. There are three ammunition types available:

• Universal: AP-T · AP · HEF-T · HEF
• 20 mm HET magazines: HEF · HEF-T · HEF · AP
• 20 mm APT magazines: AP · AP-T · AP · HEF

The R-301 is also armed with a single 3.7 cm SK C/30 cannon located on the stern. Due to the very low rate of fire at only 30 rounds per minute, the gun is not very useful for surface combat.

Additional armament

Setup 12 x 533 mm G7a torpedo

Setup 210 x EMC moored contact mine

Setup 32 x 533 mm G7a torpedo

2 x EMC moored contact mine

The R-301 features two torpedo tubes, one on each side of the hull. These fire standard German 533 mm G7a torpedo which can be found on most Kriegsmarine vessels. With a speed of 81 km/h, a payload of 358.4 kg TNTe and range of 6 km while not upgraded with torpedo mode, these make them one of the best torpedo in its class, surpassed only by Japanese Type 93 Long Lance family. When upgraded with torpedo mode, the speed decrease to 56 km/h while maximum range change to 14 km. The The R-301 can also carry up to 10 EMC moored contact mines on the slides astern behind the 3.7 cm cannon. Each of these mines have a warhead of 384 kg TNTe, capable of sinking any vessel that will sail near them. However, using the mines comes at the cost of having them exposed on the deck and risking a fatal explosion to your vessel when hit.

Usage in battles

The R-301 can be utilized as a second wave vessel, leaving the faster boats to get into battle first and supporting them from behind. Its torpedoes can be used for dealing with destroyers or armoured gunboats such as the Pr.1124 or Pr.191 series that most autocannons can not damage. The mines can be used to make minefield around capture point to deny any bluewater ship to reach and capture them for their team. Mines can be laid also into narrow passages of a strait. The R-301 can also be used to soak up enemy fire with its mostly empty bow compartment, while teammates deal with the ships attacking you.

Pros and cons

Pros:

• Lot of empty space in forward section, so it can take lot of damage
• Effective forward-facing firepower
• Has torpedoes to deal with reserve destroyers
• Large crew complement when compared to contemporaries

Cons:

• Slow
• Quite bad mobility when compared to its counterparts
• Has difficulties destroying Soviet armoured gunboats

History

Developed in the inter-war period, the R-Boots (Raumbootes) were designed as minesweepers, and they had deliberately low draughts in order to operate close to the coast. The armament was limited due to the intended mission of the ships. Propulsion was provided by two MAN marine diesel engines, providing 1,836 horsepower each and driving two shafts. Construction utilized a metal understructure and wooden framing.

424 R-Boots were completed, and they continually saw service up until 1945. They were notably used during the 1940 invasion of Norway. Only 140 of these ships survived the war, with many captured by the Allies or divided up between the Allies as spoils of war. 24 R-Boots were eventually reintroduced to the West German Navy and operated until the 1960s.

The R-Boots, despite being built as minesweepers, were forced into other roles during the war. They were used for search-and-rescue (SAR), ship hunting, coastal patrol, and convoy escort, among other duties such as minelaying. The ships were rarely used in their intended role (minesweeping) because of the defensive nature of the war for the Kriegsmarine.

R-301 was the lead ship of an R-Boot class, significantly larger than the preceding R-218. It had a length of 41 m and a displacement of 160 tons. This class consisted of R-301 through R-312, and the class was constructed from 1942 to 1945. The biggest change from the preceding classes of R-Boot was the addition of two 533 mm torpedo tubes, for use against enemy surface vessels. The R-301 class also added a third screw for increased speeds, up to 24 knots.
