Usage in the 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 5000 m and destroy the enemy bases with the setup 5 (2 x 250kg + 2 x 500kg) 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 500kg 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.

When bombing airfields, make sure to fly above 2,000m 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 6 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 7.62mm bullets.

If your plane is an early biplane armed with weak MG (2-4x 7.7mm or below), DO NOT follow behind the SB 2M's 6 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 7.62mm bullets. Instead 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 armored, you can just sit behind the SB 2M and confidently take out its crew / modules one by one, as its 7.62mm 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 (2x 7.62mm MG) with fast firerate, good trajectory and plenty of ammo allows it to deal with enemies at 6 effectively.

Cons:

• Defensive guns don't cover the belly and the sides well, and are quite light against fighters such as Bf 109 E 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.

In-game description

"In the autumn of 1940, the SB-2M-105 variant was launched into full-scale production, equipped with 1,100 hp Klimov M-105 twelve-cylinder, V-shaped, water-cooled engines and VISh-22Ye propellers.

Planes of this modification were equipped with MV-3 turrets and LU hatch mounts, and they included all of the improvements which had been applied to machines of previous variants, now implemented to the fullest extent. In particular, landing headlights and cradles for the retractable ski landing gear were mounted.

Some SB 2M-105 aircraft had a new type of glazing on the pilot's cockpit's sliding canopy to improve visibility during landing and taxiing around the airfield.

A total of 6,831 SBs were produced in all versions, including about 150 SB 2M-105s, until their production ended in early 1941. The SB bomber was the first Soviet aircraft whose licensed production was organized abroad. 110 planes designated B.71 were built in Czechoslovakia.

In addition to the USSR, SB bombers were in service with Spain, China, Czechoslovakia, Bulgaria, Germany, Slovakia, and Finland.

After their combat debut in Spain, SBs came to be used in China from February 1938 onward. Bombers of this type participated in the Battles of Lake Khasan and Khalkhyn Gol. They were used in combat operations against Poland in September 1939 and in the war with Finland in the winter of 1939-40. When World War II began, the SB was the most popular Soviet bomber. They were extensively operated as day and night bombers, as well as scout planes, on the Soviet-German front until late 1943. They took part in the war with Japan in the Far East in August 1945.

The Chinese Air Force used SBs until the end of World War II, as well as during the course of China's Civil War. Czechoslovakian B.71 planes were obtained by Germans and used as auxiliary and training vehicles. Bulgarian planes participated in the invasion of Yugoslavia in April 1941.

The Finns had about 20 captured SB bombers of various versions, mainly SB 2M-103s, which they used as scouts and anti-submarine warfare patrol aircraft.

The SB aircraft were withdrawn from service with the USSR in 1946."
