The MBR-2-M-34 was a Soviet multi-purpose flying boat designed with the intent of carrying out maritime patrol missions for the Soviet Navy. It was developed in the 1930s by Beriev OKB, with Georgy Mikhailovich Beriev at the helm of the design, and was widely used during World War II. The MBR-2-M-34 had a range of over 1,000 kilometres and was armed with various offensive weapons, such as machine guns and bombs. The name "MBR-2-M-34" stems from the aircraft's engine, the AM-34NB, which significantly enhanced its performance and reliability. Due to its versatility, the MBR-2-M-34 was well-suited for not only maritime patrol but also for use as a light bomber and even a submarine hunter. Its sturdy construction allowed it to withstand harsh weather conditions, making it well suited for maritime operations. It most likely served with the Soviet Navy until the end of World War II, at which point it started to be gradually phased out.

The MBR-2-M-34 was introduced during Update 1.57 "Battle March" as a reward vehicle for the 2016 "Chronicles of World War II". It is best used in ground battles, where it can use one of its many loadout options for CAS. Its manoeuvrability is surprisingly good for a bomber of its size, allowing it to evade enemy fighters and deliver accurate strikes on ground targets. However, while its defensive armament is adequate, key components remain vulnerable to enemy fire due to a lack of armour protection.
