The Yer-2 with upgraded ACh-30B engines plays similarly to the previous model of Yer-2's, but with overall parameters and performance improved. It has a larger payload, better defensive armament and is faster than the previous model. However, this isn't saying much considering the speed improvement is negligible and the defensive armament can easily be avoided by a skilled pilot. As such, you should avoid any form of engagement at all costs. Despite these shortcomings, the thing that gained the Yer-2 its notoriety is its massive 5,000 kg payload. The Yer-2 was the reason why you had to destroy all of the mini-bases before moving onto the airfield, as it made games last incredibly short periods of time, and a fleet of Yer-2's was almost unstoppable. In the present day however, this is not the case, and it will take multiple Yer-2's working together to destroy the bases and airfield or just one very persistent and determined Yer-2.

The Yer-2 with diesel ACh-30B engines plays similarly to the previous model of Yer-2's. It has a larger payload and better defensive armament but the heavier diesel engines mean that it is actually slower than the earlier M-105-engined variants. The airframe itself is not very durable, and with only two engines, the aircraft cannot maintain flight if one engine is knocked out. As such, it is best to avoid any form of engagement at all costs.  
  
;''Playstyles''

Like the earlier models, the diesel Yer-2 can carry one of the heaviest payloads among the heavy bombers at its battle rating: up to 5,000 kg of bombs. However, carrying the maximum payload will significantly degrade the already underwhelming flight performance of the Yer-2. Because of this, some careful planning is required in order to be able to carry the payload to its target:
  
* '''''High altitude bomber:''''' The high altitude mentality of bombers can be used, but this is hampered by the poor performance the Yer-2 offers above 4,000 meters due to its engine not receiving enough oxygen. While the safest, it is definitely the slowest. It is recommended to side climb at the start of a match to avoid confrontation and gain altitude quickly. Ideal altitude for this playstyle is around 6,000 - 6,500 meters, as you can avoid being noticed, and planes that do notice you will have trouble climbing there in a quick fashion.
+
* '''''High altitude bomber:''''' The Yer-2 can attempt to climb to high altitudes in order to avoid attracting attention, but this is hampered by the poor performance the Yer-2 offers above 4,000 m due to its engine not receiving enough oxygen. While the safest playstyle, it is definitely the slowest and most boring one. It is recommended to side climb at the start of a match to avoid confrontation and gain altitude quickly. Ideal altitude for this playstyle is around 6,000–6,500 m to avoid being noticed by fighters below (and getting a marker in Arcade and Realistic Battles), and so that the planes that do notice it will have trouble climbing there quickly. At this altitude, airfield AA defences are also not a threat.
  
* '''''Medium altitude bomber:''''' The role the Yer-2 was designed for, the player can stay around 3,000 - 4,000 meters and flank around the map towards bases. It is recommended to use this playstyle when the aircraft is spaded, as you have a higher chance of being attacked by enemy fighters who see the Yer-2 as easy prey. Maintain speed and take a long way around to bases and when you have destroyed all of them, you are free to go for ground targets.
+
* '''''Medium altitude bomber:''''' Alternatively, one can maintain around 3,000–4,000 m altitude and flank around the map towards bases. It is recommended to use this playstyle when the aircraft is fully upgraded, as there is a higher chance of being attacked by enemy fighters who see the Yer-2 as easy prey. It is highly recommended to avoid flying through the middle of the battlefield at all costs, as this is where most fighters tend to concentrate their attention on.

Description

The Yer-2 (ACh-30B) Early is a rank IV Russian bomber with a battle rating of 4.7 (AB), 4.3 (RB), and 5.3 (SB). It has been in the game since the start of the Open Beta Test prior to Update 1.27.

The Yer-2 ACh-30B is the last traditional heavy bomber in the Soviet line-up until you get to the feared Tu-4, and it retains its previous model's strengths and weaknesses. The main draw of this variant is the gigantic payload at its disposal (up to 5,000 kg), being the second best at the BR behind the British Lancaster. A squad of Yer-2's can easily win games if left alone, and thus it has gained a notoriety among players as an extremely high value target that should be destroyed at all costs, with some players even resorting to ramming the bomber if needed. The plane's defensive armament is decent for the tier, but won't stop heavily armoured interceptors such as the Fw 190 D-9, P-38L-5-LO or the feared F-82E, and thus engagements must be avoided at all costs.

Being a heavy strategic bomber, you should go for the bomb load upgrades first followed by turret 12 mm and 20 mm belts, as the ball ammo in the 12 mm belts is completely useless and the Berezin MG's belts are loaded with incendiary rounds, increasing the chance of starting fires on attackers. The rest of the modules are up to the player, but the survivability modules are recommended to withstand the beating you will be getting by fighters and interceptors.

Armaments

Suspended armament

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

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

The Yer-2 with diesel ACh-30B engines plays similarly to the previous model of Yer-2's. It has a larger payload and better defensive armament but the heavier diesel engines mean that it is actually slower than the earlier M-105-engined variants. The airframe itself is not very durable, and with only two engines, the aircraft cannot maintain flight if one engine is knocked out. As such, it is best to avoid any form of engagement at all costs.

Like the earlier models, the diesel Yer-2 can carry one of the heaviest payloads among the heavy bombers at its battle rating: up to 5,000 kg of bombs. However, carrying the maximum payload will significantly degrade the already underwhelming flight performance of the Yer-2. Because of this, some careful planning is required in order to be able to carry the payload to its target:

  • High altitude bomber: The Yer-2 can attempt to climb to high altitudes in order to avoid attracting attention, but this is hampered by the poor performance the Yer-2 offers above 4,000 m due to its engine not receiving enough oxygen. While the safest playstyle, it is definitely the slowest and most boring one. It is recommended to side climb at the start of a match to avoid confrontation and gain altitude quickly.

History

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.
