Survivability and armour

Examine the survivability of the aircraft. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armoured, etc. Describe the armour, if there is any, and also mention the vulnerability of other critical aircraft systems.


Suspended armament

The Yer-2 (ACh-30B) (e) can be outfitted with the following ordnance:

  • 20 x 100 kg FAB-100 (2,000 kg total)
  • 8 x 250 kg FAB-250M43 (2,000 kg total)
  • 4 x 500 kg FAB-500 (2,000 kg total)
  • 3 x 1,000 kg FAB-1000 (3,000 kg total)
  • 3 x 1,000 kg FAB-1000 + 20 x 100 kg FAB-100 (5,000 kg total)

  • 3 x 1,000 kg FAB-1000 + 4 x 500 kg FAB-500 (5,000 kg total)

Defensive armament

The Yer-2 (ACh-30B) (e) is defended by:

  • 1 x 20 mm ShVAK cannon, dorsal turret (200 rpg)
  • 1 x 12.7 mm Berezin UB machine gun, nose turret (195 rpg)
  • 1 x 12.7 mm Berezin UB machine gun, ventral turret (275 rpg)

Usage in battles

Describe the tactics of playing in an aircraft, the features of using vehicles 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

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".




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 If the historical reference turns out to be too big, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: and add a link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 Yer-2 twin-engine, long-range bomber with ACh-30B engines, early production series

In order to improve their flight characteristics, production Yer-2s were later equipped with more powerful Mikulin AM-35 and AM-37 engines. Tests showed that planes with these engines outperformed the original Yer-2s (with M-105 engines) in speed, rate of climb, and service ceiling, but they were not launched into full-scale production due to the engines being too “raw” for service.

So the designers fitted the aircraft with Charomsky M-30B (Ach-30B, from 1944 on) diesel engines with tractor kerosene. The production of Yer-2s with M-30B engines began in late 1943 at Irkutsk Aircraft Factory No. 39.

The aircraft was equipped with two 1,500 hp ACh-30B diesel engines with AV-5LV-116 variable-pitch propellers featuring an larger diameter than that of the VISh-22Ye.

Externally, the diesel Yer-2s differed from their predecessors in several ways: more extended fuselage contours, rudder horn balance, and changes in the design of the engine ducted-radiator shutters. The capacity of the internal fuel tanks, equipped with an inert gas pressurization system, was increased.

The aircraft's defensive armament was reinforced. The forward ball mount, with a ShKAS machine gun, was replaced with a new NU-134 forward mount with a 12.7 mm Berezin UBT machine gun featuring 195-rounds of ammunition. The LU-MV-2 hatch mount with a 7.62-mm ShKAS was replaced with an LU-MV-2B turret that had a 12.7 mm Berezin UBT machine gun with a pneumatic reloading system and 275 rounds. Instead of the TAT-BT upper mount, a TUM-5 cannon turret was installed, which had a 20 mm ShVAK cannon with 200 rounds.

The bomb bay was lengthened, and the aircraft's maximum bomb capacity was increased up to 5,000 kg. The plane was able to carry 3,000 kg (3 FAB-1000 bombs) suspended externally and 2,000 kg more inside the bomb bay. The OPB-2M bomb sight was replaced with a PS-1 synchronized sight with a special fairing. The Yer-2 became the most powerful twin-engine bomber the Soviets had.

These modifications significantly increased the bomber's takeoff weight, which required new landing gear wheels with an enlarged diameter. Only 2 Yer-2 aircraft were produced at Irkutsk Aircraft Factory No. 39 during the whole year of 1943. 47 more Yer-2s with a single-seat pilot's cockpit were built, until August 1944 when bombers with a two-seat pilot's cockpit started to be produced."


Excellent additions to the article would be video guides, screenshots from the game, and photos.
