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 B Mk I|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.
+
The Yer-2 (ACh-30B) is a long-range twin-engine bomber capable of carrying a very heavy payload of bombs (up to 5,000 kg) over shorter distances. It is the final, definitive production model of the Yer-2, equipped with Charomskiy ACh-30B diesel engines for improved fuel economy and range. It can be distinguished from the [[Yer-2 (ACh-30B) (e)|early model]] by the widened cockpit.

<!-- ''Describe how the aircraft behaves in the air. Speed, manoeuvrability, acceleration and allowable loads - these are the most important characteristics of the vehicle.'' -->
 +
The Yer-2's ACh-30B diesel engines were optimised for fuel economy and not pure performance. Thus, the ACh-30B-engined model is actually slower than the earlier M-105-engined models, especially because the diesel engines are significantly heavier than the earlier gasoline engines. The other aspects of its flight performance are unremarkable compared to other contemporary heavy bombers. It should also be kept in mind that the already poor flight performance is significantly degraded when carrying the maximum 5,000 kg payload.
 +
 
 +
The Yer-2 is also by no means an agile aircraft in the first place and the airframe will not tolerate much G-load, hence it is very ill-advised to make sudden control inputs with the aircraft unless playing in Arcade mode. In fact, the later diesel Yer-2 model has even lower structural G-tolerance than the [[Yer-2 (ACh-30B) (e)|early]] diesel-engined model.

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 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.

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 is the last traditional heavy bomber in the Soviet line-up until the [[Tu-4]], and it retains its previous models' strengths and weaknesses. The main draw of the diesel Yer-2s is the gigantic payload at its disposal (up to 5,000 kg), being the second best at the BR behind the British [[Lancaster B Mk I|Lancaster]]. However, the heavier diesel engines mean that it is actually slower than the earlier M-105-engined variants.
  
;''Playstyles''
+
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. The late model diesel Yer-2 has a side-by-side pilot cockpit arrangement, but is otherwise near identical to the early diesel Yer-2.
  
* '''''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.
+
Carrying the maximum payload will also 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:
  
* '''''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.
+
* 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. Ideally, one should climb to 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: 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.
 +
 
 +
It is also important to note that the Yer-2 cannot spawn on airfields in Simulator Battles, as the take-off run is too long. It will thus be freshly spawned in the air at the very rear edge of the team's side of the map. However, if a successful landing is made on one of the airfields, the Yer-2 can be respawned in the air over that airfield instead.

Description

The Yer-2 (ACh-30B) Late is a rank IV Soviet bomber with a battle rating of 4.7 (AB), 4.3 (RB), and 5.7 (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 a long-range twin-engine bomber capable of carrying a very heavy payload of bombs (up to 5,000 kg) over shorter distances. It is the final, definitive production model of the Yer-2, equipped with Charomskiy ACh-30B diesel engines for improved fuel economy and range. It can be distinguished from the early model by the widened cockpit.

The Yer-2's ACh-30B diesel engines were optimised for fuel economy and not pure performance. Thus, the ACh-30B-engined model is actually slower than the earlier M-105-engined models, especially because the diesel engines are significantly heavier than the earlier gasoline engines. The other aspects of its flight performance are unremarkable compared to other contemporary heavy bombers. It should also be kept in mind that the already poor flight performance is significantly degraded when carrying the maximum 5,000 kg payload.

The Yer-2 is also by no means an agile aircraft in the first place and the airframe will not tolerate much G-load, hence it is very ill-advised to make sudden control inputs with the aircraft unless playing in Arcade mode. In fact, the later diesel Yer-2 model has even lower structural G-tolerance than the early diesel-engined model.

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 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

Defensive armament

The Yer-2 (ACh-30B) (l) 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 is the last traditional heavy bomber in the Soviet line-up until the Tu-4, and it retains its previous models' strengths and weaknesses. The main draw of the diesel Yer-2s is the gigantic payload at its disposal (up to 5,000 kg), being the second best at the BR behind the British Lancaster. However, 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. The late model diesel Yer-2 has a side-by-side pilot cockpit arrangement, but is otherwise near identical to the early diesel Yer-2.

Carrying the maximum payload will also 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. Ideally, one should climb to 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: 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.

It is also important to note that the Yer-2 cannot spawn on airfields in Simulator Battles, as the take-off run is too long. It will thus be freshly spawned in the air at the very rear edge of the team's side of the map. However, if a successful landing is made on one of the airfields, the Yer-2 can be respawned in the air over that airfield instead.

Pros and cons

Pros:

  • Massive payload.
  • Relatively powerful defensive armament.
  • Has two pilots for redundancy.

Cons:

  • Very poor flight performance, especially with the maximum bomb load.
  • Has only two engines, cannot sustain flight with only one engine working.
  • Wings are massive, flimsy and littered with fuel tanks.
  • Performance suffers significantly above 4,000 metres.
  • Pilots are placed very close to each other.

History


Archive of the in-game description

The command staff of the Long-Range Air Force (LRAF) proposed adding a second pilot to the Yer-2's crew, placing him next to the commander. This decision significantly reduced the workload imposed on pilots during long flights.

The pilot's cockpit now had two seats, and its appearance was completely changed. The pilots' chairs were located side by side (the commander's to the left and the co-pilot's to the right) under the improved canopy, which was now the classical type instead of the earlier asymmetrical version.

The navigator's station was shifted to the forward section of the fuselage. The elliptical outlines of the forward section common to the Yer-2 were now straightened, and the upper section of the navigator's cockpit was lowered. These improvements only barely influenced the plane's flight characteristics, but they noticeably improved visibility from the pilot's cockpit. The navigator's work with his sextant became easier, thanks to the transparent astrodome.

An OPB-2R sight was mounted instead of the PS-1 sight, resulting in the removal of its external fairing.

Yer-2 bombers with the new two-seat cockpit and the new navigator's cockpit were produced at Factory No. 39 beginning in August 1944. 101 aircraft were built. Production continued into 1945, with the number of planes reaching 241.

Yer-2 bombers built at the factory in Irkutsk entered service beginning in February 1944. Although these aircraft reached the front line when the war with Germany was almost over, they were used actively enough on the Northwestern and Baltic Fronts. Yer-2s made a significant contribution to the successful assault of the fortress city of Königsberg with their large-sized bombs.

Based on their combat experience, the various crews formed a generally favourable attitude towards the Yer-2, built with ACh-30B diesel engines. The pilots liked its comfortable cockpit with excellent visibility, powerful defensive armament, large bomb capacity, and strong airframe structure. The aircraft's high survivability was also noted. Yer-2s with diesel engines practically never caught fire, since kerosene was much more difficult to ignite than petrol.

Yer-2 bombers were withdrawn from service in 1946.
