Survivability and armour

There is 8.5 mm of steel plate armor on the seat of the pilot, and 10 mm of steel armor for both gunners at the rear of the aircraft. The fuel tank is all around the plane so the chance of catching on fire is high. The pilot is rather hard to hit, considering its seated at an elevated position when compared to the rest of the crew, which the enemy fighters or interceptors might not be aiming for since the gunner are the most dangerous defensive armaments of the aircraft, an its not easy to aim for that extended cockpit.


Suspended armament

Main article: Suspended armaments

The Yer-2 (M-105) can be outfitted with the following ordnance:

  • 12 x 50 kg FAB-50 (600 kg total)
  • 12 x 100 kg FAB-100 (1,200 kg total)
  • 14 x 100 kg FAB-100 (1,400 kg total)
  • 4 x 250 kg FAB-250M43 (1,000 kg total)
  • 6 x 250 kg FAB-250M43 (1,500 kg total)
  • 4 x 500 kg FAB-500 (2,000 kg total)
  • 6 x 500 kg FAB-500 (3,000 kg total)
  • 2 x 1,000 kg FAB-1000 (2,000 kg total)
  • 2 x 1,000 kg FAB-1000 + 4 x 500 kg FAB-500 (4,000 kg total)

Defensive armament

Main article: ShKAS (7.62 mm)

The Yer-2 (M-105) is defended by:

  • 1 x 7.62 mm ShKAS machine gun, nose turret (500 rpg)
  • 1 x 7.62 mm ShKAS machine gun, dorsal turret (1,200 rpg)
  • 1 x 7.62 mm ShKAS machine gun, ventral turret (1,075 rpg)

Usage in battles

The Yer-2 (M-105) is an impressive aircraft for it's time, considering the bomb-load makes up of 56% of its weight an it was able to, well, still fly! (although there was a crash of the prototype, which was designated Stal-7, during takeoff. This led to the arrest of the original designer before Yermolayev undertook the design.) In Arcade battles, the weight of the aircraft would't affect the gameplay too much. However, that's a different story for players who play this aircraft in Air RB. The weight of the bomb-load significantly affects the performance of the aircraft, making it a pain to fly to its destination because it has a subpar climb rate, and its painfully slow (stock: average of ~263km/h at 5,000 m). Luckily, this is a long range bomber, and this allows you to spawn at an altitude of 4,000 m. The player should not start diving immediately because the slow speed and the lack of defensive armaments on the aircraft makes this aircraft an easy target for enemy fighters, especially for those with 8 x .50 cal machine guns. As a long range bomber, your best ally would be altitude. The higher you are, the more chance you have at surviving (Enemy aircrafts would usually leave you alone when you're at 5,000 m). Avoid flying into the middle of the battlefield to prevent dropping your K/D ratio. Try taking routes around the map and far from the battle because it won't be long before 4 fighters aircrafts start appearing at your rear. If an enemy does appear at your six, drop your bomb-load immediately at the target and return to base. If you weren't able to do so, return to the base whatsoever. Start diving to the direction of the airbase, this will increase the effectiveness of putting out a fire, and pray that you're able to take him done before the enemy does that to you.

Pros and cons

Summarize and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".


  • Impressive Load-out.
  • Altitude advantage over spawn. (4,000 m)
  • Ability to deal massive damage to the target with its bomb-load.
  • Engine doesn't overheat easily when using WEP.


  • Terrible climb rate. (For 4.0)
  • Subpar speed. (For 4.0)
  • Players may experience trouble during takeoff.


Describe the history of the creation and combat usage of the aircraft in more detail than in the introduction. If the historical reference turns out to be too big, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: and add a link to it here using the main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === Encyclopedia Info ===, also if applicable).

In-game description

"Yermolayev DB-240 (Yer-2) twin-engine long-range bomber

A four-seat, all-metal monoplane with an inverted gull wing, a twin-fin tail, and a retractable landing gear system including a tail wheel. This plane was designed by OKB-240, under the direction of V. G. Yermolayev. The DB-240 was based on the Stal-7 passenger aircraft designed at the Civil Air Fleet Research Institute under the direction of R. L. Bartini.

The DB-240 prototype got off the ground for the first time on May 14, 1940. Full-scale production of the aircraft, under the designation of Yer-2, was started in May 1941 at Voronezh Aircraft Factory No. 18.

Originally, the DB-240 was designed with the promising M-106 liquid-cooled engines in mind. However, the development of the M-106 took longer than expected, and the designers urgently had to revise the whole project since the M-105 engines were less powerful and designed for lower altitudes but had already been launched into full-scale production. This forced replacement of the power unit significantly reduced the DB-240's combat capabilities, since its speed and altitude were noticeably decreased.

Yer-2s of the first production series were equipped with 1,100 hp Klimov M-105 twelve-cylinder, V-shaped, liquid-cooled engines with three-bladed variable-pitch metal VISh-22Ye propellers.

The aircraft's defensive armament included three turrets. One 7.62 mm ShKAS belt-fed machine gun with 500 rounds was hinged in the navigator's nose mount just like it had been on the DB-3F. A Mozharovsky-Venevidov LU-MV-2 hatch mount was fitted in the lower rear hatch between the 18th and the 21st frames. The mount was retracted in the fuselage when in the travelling position or extended before firing. A 7.62 mm ShKAS machine gun with an OP-2L optical sight and 1,075 rounds was mounted on a mobile carriage. The first production aircraft had Mozharovsky-Venevidov MV-3 turrets, with a 7.62 mm ShKAS machine gun featuring an OPT-1 sight and 1,200 rounds. Then, heavy TAT-VT turrets started to be delivered, and the light MV-3 turret was replaced with a heavy TAT-VT aerodynamic turret featuring a 12.7 mm Berezin BT machine gun with 400 rounds.

The aircraft's bombing armament included two external Der-19-20 beams enabling it to suspend bombs weighing from 100 to 1,000 kg (FAB-100, FAB-250, FAB-500, FAB-1000, BRAB-220, BRAB-500, BRAB-1000, P-250). The fuselage bomb bay had inside a pair of KDZ-240 twin cluster bomb racks designed to suspend four FAB-250 or FAB-500 bombs, as well as four KD2-240 triple cluster bomb racks designed to suspend 12 FAB-50 or FAB-100 bombs. External suspension enabled the aircraft to carry two VAP-500 spray tanks or the same number of UKhAP-500 all-purpose chemical tanks to create smoke screens. Four ABK-240 bomb clusters could be suspended inside the bomb bay, with bomblets up to 15 kg or incendiary ampoules. The Yer-2's maximum bomb capacity for short distances was 4,000 kg (two FAB-1000s on the outside and four FAB-500s suspended inside)."
