Usage in battles

Describe the tactics of playing in the aircraft, the features of using aircraft in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons

Pros:

• Impressive bomb loadout options
• Gets a Long Range Bomber air-spawn at 4,500 m altitude
• Ability to deal massive damage to the targets with its immense bomb-load
• Engine doesn't overheat easily when using WEP

Cons:

• Terrible climb rate for its BR
• Subpar speed for its BR
• Weak defensive armament
• Poor performance at high altitude
• Very easy target to be destroyed, littered with fuel tanks, and is an easy target in general
• Difficult to takeoff with larger bomb loads if with mostly stock performance

History

Archive of the in-game description

Yermolayev Yer-2 twin-engine long-range bomber with M-105R engines Yer-2s of later production series had 1,100 hp Klimov M-105R twelve-cylinder V-shaped geared liquid-cooled engines. This engine was specially created to be installed on bombers, and it differed from the M-105 in that it had a smaller gear ratio. Externally, M-105R engines differed from M-105s by having individual exhaust pipes instead of twin exhaust manifolds on the side cowlings. The standard configuration of Yer-2s of later production series included a TAT-VT upper turret with a 12.7 mm Berezin BT machine gun. Instead of the LU-MV-2 hatch mount with a 7.62 mm ShKAS, the aircraft was given an LU-MV-2B mount with a 12.7 mm BT machine gun featuring a manual reloading system and fed from detachable magazines. The total magazine capacity was 240 rounds. The Yer-2 bomber outperformed the DB-3F's maximum and cruise speed, as well as its flight range (with a normal combat load). In comparison to the DB-3F, the Yer-2 was easier to pilot. But the relatively low critical altitude of the M-105 engines meant that combat missions with the Yer-2 were very risky, since the chance of being hit by anti-aircraft gun fire or intercepted by enemy fighters was higher, and the plane was also more affected by weather conditions on its route. In addition, the Yer-2 had unsatisfactory longitudinal and lateral stability, due to the large loads imposed on the aircraft's flight controls. The insufficient power of M-105 engines dramatically increased the runway length required for takeoff. When World War II started, no Yer-2s yet served with the Soviet troops. The first bomber air regiment to use this aircraft was formed in August of 1941. Yer-2 bombers flew their first sortie on August 10, 1941, when they participated in a raid over Berlin. Regiments armed with Yer-2s acted as day and night bombers on the Western Front. They bombed Polotsk, Minsk, Orsha, Vitebsk, Novgorod, and Smolensk. In November 1941, Yer-2s attacked Königsberg. Yer-2 bombers with M-105 engines fought until May 1942, but some machines were flown until late 1943. The production of Yer-2s with M-105 engines was discontinued in September 1941. A total of 71 aircraft had been built.
