The '''{{Specs|name}}''' '''({{Specs|pseudonym}})''' is a gift rank {{Specs|rank}} British tank destroyer {{Battle-rating}}. It was introduced during [[Update 1.95 "Northern Wind"]] in the [[wt:en/news/6521-special-operation-f-r-o-s-t-en|Operation F.R.O.S.T.]] event. It features a heavily modified Ram chassis with a powerful 94 mm AA cannon, playing as a British counterpart of the German [[VFW]] and the two can often face each other in the battlefield.
+
The '''{{Specs|name}}''' is a gift rank {{Specs|rank}} Soviet bomber {{Battle-rating}}. Though initially in the game pre-1.29, this plane was removed upon Update 1.37 due to redundancy. Those players who acquired the aircraft before it was removed still have access to it.

+
=== Survivability and armour ===
−
The {{PAGENAME}} possesses light armour in the upper area of the turret (''10 mm'' thickness), that might only cover your crew for small caliber machine guns.
+
''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.''
  
−
Lying hidden in the back of the turret, its heavy 94 mm cannon is protected by ''20 mm'' of structural steel located lower the cannon gun. Inside it the vertical aim drive is located. If a shot goes through and detonates inside this boxy structure, it will cause damage to your crew and the vertical aiming drive. This is the most common damage the {{PAGENAME}} will get, as the enemy often shoots at the area below the 94 mm cannon.
+
== Armaments ==
 +
=== Suspended armament ===
 +
<!-- ''Describe the aircraft's suspended armament: additional cannons under the wings, bombs, rockets and torpedoes. This section is especially important for bombers and attackers. If there is no suspended weaponry remove this subsection.'' -->
 +
{{main|FAB-100 (100 kg)|FAB-250M43 (250 kg)|FAB-500 (500 kg)}}
  
−
The thicker part of the armour is located in the cannon structure, visible in the centre of the turret (''60 mm'' thickness). But due to the structural steel armour type, its armour remains insignificant for the heavy shells it can face, making cannon breach damage a routine situation as shells with explosive filler detonate within the structure
+
The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:
  
−
More armour is located in the lower central area of the transmission. There, the transmission mounting provides '''50.8 mm''' of armour thickness, thick enough that it is possible to stop awkwardly angled shots or HE shots, but won't save you from a frontal encounter. Damages through here also will damage the transmission module.

−
Due to the {{PAGENAME}}'s provided armour, any cannon shell sent its way can completely cripple your ability to retaliate. However, the {{PAGENAME}}'s crew helps provide a factor in the vehicle's survivability on the battlefield.

 +
* 1 x 7.62 mm ShKAS machine gun, ventral turret (500 rpg)

 +
'''Arcade Battles:'''
  
−
* 1 Gunner
+
This bomber is quite fast for its BR so you should use this as an advantage. For example, you should climb directly at the beginning of the match to 5,000 m and destroy the enemy bases with setup 5 (2 x 250 kg + 2 x 500 kg) which is the heaviest payload you'll have with this plane.
−
* 2 Loaders
 
−
* 2 Machine gunners
 
−
* 1 Commander
 
−
* 1 Driver
 
  
−
This gives the {{PAGENAME}} one more crew member over the VFW for an edge in crew surviability, though the trade-off is that the Ram's crew is more heavily exposed. Both loaders are the most vulnerable targets as they stand back uncovered. The driver and a machine gunner remain in the safest spot within the vehicle chassis. The gunner it well placed but often gets knocked out. High crew skills are a must to ensure higher chance of resisting explosive effects or shrapnel, while performing gun reloads and field repairs even faster to fight back against the opponents.
+
'''Realistic Battles:'''
  
−
The best way to utilize the armour to protect the crew is to aim the gun from the front, as it provides cover to both loaders in the back. However, avoid getting hit once as the proximity of the crew members, modules, and ammo racks within each other on the {{PAGENAME}} means a single hit has a chance of crippling the vehicle's performance enough for follow-up shots to finish the {{PAGENAME}} off.
+
In Realistic battles you should use the same tactics as in Arcade battles. Note that 2 x 500 kg FAB 500 bombs are enough to destroy a base.
  
−
=== Mobility ===
+
'''Simulator Battles:'''
−
<!-- ''Write about the mobility of the ground vehicle. Estimate the specific power and manoeuvrability, as well as the maximum speed forwards and backwards.'' -->
 
  
−
{{tankMobility|abMinHp= 568|rbMinHp= 354}}
+
In Sim, the overall tactic remains the same as other bombers: base/airfield bombing. However, there are several notes for this particular SB 2M bomber.
  
−
Mobility is decent for a SPG with such a gun, thanks to its light armour. 43 km/h in AB, 40 km/h in RB/SB.
+
Maybe it's because of the design of short fuselage and huge wings, or it's caused by something else, the SB 2M is super hard to control in the pitch. If you leave the stick at the deadzone, the aircraft will automatically climb or dive which will lead to a crash if unnoticed. Trimming doesn't help. For the gunner view, even though you might have the "autopilot when in gunner view" enabled, it won't help either, as it will still continuously pitch up and down like a boat. Also note that when switching to gunner view, it will sometimes uncontrollably roll to one side which will make it enter a spin quickly. Therefore this bomber is extremely frustrating to fly in Sim.
  
−
The {{PAGENAME}} is able to reach its maximum speed of 40 km/h (RB) in off road terrain quite easily. Not enough to do a flanking manoeuvre, but enough to get a good sniping location or position early in the match.  
+
Note: the setup with the most explosive mass is the 2x 250 kg + 2x 500 kg, but this way the two 500 kg bombs are carried under the wing roots and the two 250 kg inside the bomb bay. So if you use the default keybind (space) to open bomb bay ''and'' drop bombs, the timing will get messed up when bombing a base, since the two wing-mounted bombs will go first, ''then'' the bomb bay opens, dropping the two inside. The time between the two drops are long enough for one drop to completely miss the target. To avoid this, set up a keybind for open / close bomb bay, and drop bomb series (all bombs go at once). When approaching a base, open the bomb base first, then drop all the bombs, they will now all hit the target.
  
−
Its reverse speed is quite poor, 5.7 km/h in AB and 5.2 km/h in RB/SB. However, this is enough for retreating from a sniping position effectively.
+
When bombing airfields, make sure to fly above 2,000 m to avoid the AAA, as this plane is unprotected and its coolers will often get damaged, leading to the engines overheating. You should familiarise each module of the airfield to maximise the damage. The airstrip is the most visible and the easiest one to hit, however bombing it seems to halve your reward. So it is recommended to bomb everything else: hangar, fuel area, living quarters, etc. The plane hangars are probably easy, since they aren't too small.
  
−
Close quarters should be avoided as it would just make the {{PAGENAME}} quickly spotted and flanked by enemy forces.
+
'''Against the SB 2M (all modes but mostly in sim):'''
  
−
== Armaments ==
+
You should be very careful against bombers since with the Sim control (whether it be mouse joystick or a real stick) the plane will manoeuvre much more gently, making yourself a great target for the bomber's gunners. DO NOT follow behind the SB 2M's six unless you are sure that its tail gunners are unconscious. Chasing behind the SB 2M makes yourself pretty much stationary for the tail gunners, and you will be showered with 7.62 mm bullets.
−
=== Main armament ===
 
−
<!--Give the reader information about the characteristics of the main gun. Assess its effectiveness in a battle based on the reloading speed, ballistics and the power of shells. Do not forget about the flexibility of the fire, that is how quickly the cannon can be aimed at the target, open fire on it and aim at another enemy. Add a link to the main article on the gun: <code><nowiki>{{main|Name of the weapon}}</nowiki></code>. Describe in general terms the ammunition available for the main gun. Advise about how to use them and how to fill the ammunition storage.-->
 
−
{{main|OQF Mk.II (94 mm)}}
 
  
−
The 94 mm cannon provides very lethal penetration for all the enemy it faces. It's different from any other cannon in the British tree until battle rating 5.0, as this cannon holds a lower muzzle velocity than your usual 17pdr. Therefore some practice should be made to familiarize with the new cannon ballistics.  
+
If your plane is an early biplane armed with weak MG (2-4 x 7.7 mm or below), you should use deflection shots. That is, imagine yourself as an anti-air missile, predict where you two will meet and fly towards that point. This way it gives the gunners little window to open fire at you. When firing, try to aim for the cockpit for a possible pilot-snipe, as the pilot is very unprotected. Or aim at its engines to damage it or the cooler. Without an engine the SB 2M won't fly far.
  
−
===== Ammunition =====
+
If you are flying an interceptor/heavy fighter that is heavily armed and armoured, you can just sit behind the SB 2M and confidently take out its crew/modules one by one, as its 7.62 mm MG has rather weak penetration and damage. This is the most precise way of damaging an aircraft, however the safest tactic is still, and will always be deflection shooting. One accurate burst will critically damage the weak airframe of the SB 2M, or snap off its wing straight away.

In Realistic/Simulator battles, the best approach is the sniping role. Quickly find an appropriate spot at the beginning of the match. The vehicle is tall and the gun depression is only of -5° so keep that in mind when positioning. Covering the allies flanks, long roads, taking down enemy snipers, or keeping the enemy from capturing a point shall be your duty.
 
−
 
−
A good tactic is to wait enemies expose their sides. Tiger and Panther tanks don't have the armour to resist the 94 mm cannon, and so one shot will usually be enough. The 44 shells it can carry is sufficient for prolonged sniper duties. The same can be said of Soviet vehicles, as their frontal armour tends to ricochet rounds, so it's recommended to aim at the sides as well. As enemies pass by, wait for the right moment to shoot, but make sure to correctly range the targets and lead the gun to successfully land the first shot.
 
−
 
−
This tactic can be more successful with camouflage on the frontal armour. Concealing the {{PAGENAME}} in the woods as well as hiding the exposed loaders in the back from easy picking.
 
−
 
−
Shooting the enemies frontal armour is possible, but the risk of shots bouncing off is still high, despite the gun's penetration capabilities. This will also expose the {{PAGENAME}}'s position, which will lead enemies to pour down machine gun fire, artillery, and aerial strikes to suppress and eliminate the {{PAGENAME}}.

−
* Powerful gun
+
* Adequate speed for a bomber, allowing it to get to targets quickly
−
* Capable of penetrating every enemy it can face from the front
+
* Great turn rate allows it to change direction quickly, or to even dodge attacks
−

−
* Not very fast
+
* Crew and important parts (eg. fuel tank, engines, coolers) lack protection, increasing the chance of being pilot-sniped or critically damaged. Combined with its weak airframe, it is vulnerable to heavy fighters like [[Ju 88 (Family)|Ju 88]].
−
* Slow gun traverse
+
* In Simulator, it is extremely hard to control. No matter how precisely you trim, it will always automatically pitch up and down. Also when switching to gunner view, it will roll, causing a death spin.

=== In-game description ===
 +
In 1937, designers under the direction of A. A. Arkhangelski began working to improve the SB even more. The aircraft received a 960 hp Klimov M-103 twelve-cylinder, V-shaped, liquid-cooled engine. The M-103 engine, created in 1936-37, was based on the M-100.
 +
 
 +
After testing was performed, the SB 2M-103 bomber was launched into full-scale production in 1938 under the designation of "96th series".
 +
 
 +
SB 2M-103 planes of the 96th series had external DER-19 bomb racks under the centre wing section that were designed to carry aerial bombs weighing up to 500 kg. The aircraft's maximum bomb capacity was increased up to 1,500 kg. DER-19 racks could house external teardrop-shaped fuel tanks with a capacity of 370 litres each.
 +
 
 +
To improve reliability, a mechanical bomb release system was introduced and also duplicated in the pilot's cockpit. The aircraft was equipped with an AFA-13 photo camera. An electrohydraulic landing gear retraction system was used, and the pilot's chair received an armored backrest. Due to these many changes, the aircraft's flight weight increased significantly, and the airframe's structure was strengthened.

In 1941, General Frederick 'Frank' Worthington, founder of the Canadian Armoured Corps, proposed that a 3.7 inch anti-aircraft gun be mounted on a Ram chassis to act as a mobile anti-tank gun. The OQF MK II was the primary British heavy AA guns during World War II. The Canadians used this gun for experimenting, mounting it on the Ram chassis. Few examples were made and one was sent to Great Britain for trials, but no further development came of it.

From this point on, all production SB 2M-103s began to be produced with a shielded MV-3 gun turret and an LU hatch mount with an optical sight. An inert gas filling system was introduced for the fuel tanks.

Planes of later production series had modified M-103U and M-103A engines. These engines were equipped with ducted coolant radiators located over the engine. The power unit cowling was completely changed. For this, the engine oil coolers were moved to the leading edge of the outer wing.

This SB 2M-103 with ducted radiators became the most high-speed model among production SB bombers, reaching a speed of 450 km/h at a height of 4,100 m. These bombers were produced full-scale from 1939-40, being nicknamed "Shchuka" ("Pike", as a fish) among the troops, due to the distinctive form of their engine cowls.

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.

Armaments

Suspended armament

Main articles: FAB-100 (100 kg), FAB-250M43 (250 kg), FAB-500 (500 kg)

The SB 2M-103 MV-3 can be outfitted with the following ordnance:

  • 6 x 100 kg FAB-100 bombs (600 kg total)
  • 2 x 250 kg FAB-250M43 bombs + 6 x 100 kg FAB-100 bombs (1,100 kg total)
  • 2 x 250 kg FAB-250M43 bombs (500 kg total)
  • 4 x 250 kg FAB-250M43 bombs (1,000 kg total)
  • 1 x 500 kg FAB-500 bomb (500 kg total)
  • 2 x 500 kg FAB-500 bombs + 2 x 250 kg FAB-250M43 bombs (1,500 kg total)
  • 3 x 500 kg FAB-500 bombs (1,500 kg total)
  • 1 x 500 kg FAB-500 bomb + 2 x 250 kg FAB-250M43 bombs (1,000 kg total)

Defensive armament

Main article: ShKAS (7.62 mm)

The SB 2M-103 MV-3 is defended by:

  • 2 x 7.62 mm ShKAS machine gun, nose turret (960 rpg = 1,920 total)
  • 1 x 7.62 mm ShKAS machine gun, dorsal turret (1,000 rpg)
  • 1 x 7.62 mm ShKAS machine gun, ventral turret (500 rpg)

Usage in battles

Arcade Battles:

This bomber is quite fast for its BR so you should use this as an advantage. For example, you should climb directly at the beginning of the match to 5,000 m and destroy the enemy bases with setup 5 (2 x 250 kg + 2 x 500 kg) which is the heaviest payload you'll have with this plane.

Realistic Battles:

In Realistic battles you should use the same tactics as in Arcade battles. Note that 2 x 500 kg FAB 500 bombs are enough to destroy a base.

Simulator Battles:

In Sim, the overall tactic remains the same as other bombers: base/airfield bombing. However, there are several notes for this particular SB 2M bomber.

Maybe it's because of the design of short fuselage and huge wings, or it's caused by something else, the SB 2M is super hard to control in the pitch. If you leave the stick at the deadzone, the aircraft will automatically climb or dive which will lead to a crash if unnoticed. Trimming doesn't help. For the gunner view, even though you might have the "autopilot when in gunner view" enabled, it won't help either, as it will still continuously pitch up and down like a boat. Also note that when switching to gunner view, it will sometimes uncontrollably roll to one side which will make it enter a spin quickly. Therefore this bomber is extremely frustrating to fly in Sim.

Note: the setup with the most explosive mass is the 2x 250 kg + 2x 500 kg, but this way the two 500 kg bombs are carried under the wing roots and the two 250 kg inside the bomb bay. So if you use the default keybind (space) to open bomb bay and drop bombs, the timing will get messed up when bombing a base, since the two wing-mounted bombs will go first, then the bomb bay opens, dropping the two inside. The time between the two drops are long enough for one drop to completely miss the target. To avoid this, set up a keybind for open / close bomb bay, and drop bomb series (all bombs go at once). When approaching a base, open the bomb base first, then drop all the bombs, they will now all hit the target.

When bombing airfields, make sure to fly above 2,000 m to avoid the AAA, as this plane is unprotected and its coolers will often get damaged, leading to the engines overheating. You should familiarise each module of the airfield to maximise the damage. The airstrip is the most visible and the easiest one to hit, however bombing it seems to halve your reward. So it is recommended to bomb everything else: hangar, fuel area, living quarters, etc. The plane hangars are probably easy, since they aren't too small.

Against the SB 2M (all modes but mostly in sim):

You should be very careful against bombers since with the Sim control (whether it be mouse joystick or a real stick) the plane will manoeuvre much more gently, making yourself a great target for the bomber's gunners. DO NOT follow behind the SB 2M's six unless you are sure that its tail gunners are unconscious. Chasing behind the SB 2M makes yourself pretty much stationary for the tail gunners, and you will be showered with 7.62 mm bullets.

If your plane is an early biplane armed with weak MG (2-4 x 7.7 mm or below), you should use deflection shots. That is, imagine yourself as an anti-air missile, predict where you two will meet and fly towards that point. This way it gives the gunners little window to open fire at you. When firing, try to aim for the cockpit for a possible pilot-snipe, as the pilot is very unprotected. Or aim at its engines to damage it or the cooler. Without an engine the SB 2M won't fly far.

If you are flying an interceptor/heavy fighter that is heavily armed and armoured, you can just sit behind the SB 2M and confidently take out its crew/modules one by one, as its 7.62 mm MG has rather weak penetration and damage. This is the most precise way of damaging an aircraft, however the safest tactic is still, and will always be deflection shooting. One accurate burst will critically damage the weak airframe of the SB 2M, or snap off its wing straight away.

Pros and cons

Pros:

  • Adequate speed for a bomber, allowing it to get to targets quickly
  • Great turn rate allows it to change direction quickly, or to even dodge attacks
  • Nice payload allows it to finish off a base in one go, or destroy tanks / pillboxes easily
  • Great defensive firepower at the tail (2 x 7.62 mm MGs) with fast firerate, good trajectory and plenty of ammo allows it to deal with enemies on its six effectively

Cons:

  • Defensive guns don't cover the belly and the sides well, and are quite light against fighters such as Bf 109 E-1 or Ki-61
  • Crew and important parts (eg. fuel tank, engines, coolers) lack protection, increasing the chance of being pilot-sniped or critically damaged. Combined with its weak airframe, it is vulnerable to heavy fighters like Ju 88.
  • In Simulator, it is extremely hard to control. No matter how precisely you trim, it will always automatically pitch up and down. Also when switching to gunner view, it will roll, causing a death spin.

History

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 long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

In-game description

In 1937, designers under the direction of A. A. Arkhangelski began working to improve the SB even more. The aircraft received a 960 hp Klimov M-103 twelve-cylinder, V-shaped, liquid-cooled engine. The M-103 engine, created in 1936-37, was based on the M-100.

After testing was performed, the SB 2M-103 bomber was launched into full-scale production in 1938 under the designation of "96th series".

SB 2M-103 planes of the 96th series had external DER-19 bomb racks under the centre wing section that were designed to carry aerial bombs weighing up to 500 kg. The aircraft's maximum bomb capacity was increased up to 1,500 kg. DER-19 racks could house external teardrop-shaped fuel tanks with a capacity of 370 litres each.

To improve reliability, a mechanical bomb release system was introduced and also duplicated in the pilot's cockpit. The aircraft was equipped with an AFA-13 photo camera. An electrohydraulic landing gear retraction system was used, and the pilot's chair received an armored backrest. Due to these many changes, the aircraft's flight weight increased significantly, and the airframe's structure was strengthened.

From this point on, all production SB 2M-103s began to be produced with a shielded MV-3 gun turret and an LU hatch mount with an optical sight. An inert gas filling system was introduced for the fuel tanks.

Planes of later production series had modified M-103U and M-103A engines. These engines were equipped with ducted coolant radiators located over the engine. The power unit cowling was completely changed. For this, the engine oil coolers were moved to the leading edge of the outer wing.

This SB 2M-103 with ducted radiators became the most high-speed model among production SB bombers, reaching a speed of 450 km/h at a height of 4,100 m. These bombers were produced full-scale from 1939-40, being nicknamed "Shchuka" ("Pike", as a fish) among the troops, due to the distinctive form of their engine cowls.

From December 1939 on, all SB bombers were equipped with VISh-22 three-bladed, controllable-pitch propellers.
