Description

GarageImage Yer-2 (ACh-30B) (e).jpg


The Yer-2 (ACh-30B) Early is a rank IV Russian bomber with a battle rating of 5.0 (AB), 4.7 (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.

Armaments

Suspended armament

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

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

Playstyles
  • 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.
  • 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.

  • 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.

Pros and cons

Pros:

  • Massive payload, second best of any non-premium bomber at the BR
  • Relatively powerful defensive armament
  • Two pilots, if one gets knocked out the other can still fly

Cons:

  • Very slow
  • Defensive armament won't do anything versus heavily armoured interceptors.
  • Wings are massive and flimsy, making them easy targets
  • Even for a heavy bomber, the manoeuvrability is poor
  • Performance suffers significantly above 4,000 meters
  • Carrying the largest payload has a noticeable effect on performance
  • Wings are littered with fuel tanks
  • Pilots are placed very close to each other
  • Reputation; Enemies will climb to your altitude specifically to destroy you due to your notoriety

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.
