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.

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.

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.

  • 2 x 7.62 mm ShKAS machine guns, 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 />.

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.
