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.

Usage in 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.
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.
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 bay 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 anti-aircraft artillery, 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.
Given its huge wings compared to the rather skinny fuselage, it can be tricky to land as it will bounce off the ground and leap into the air again and again, no matter how slow it seems to fly. The trick is to slow it down more than any other twin-engine plane, plus set up key binds for "flaps down" and "flaps up" to replace the default "toggle flaps". This way you can use the wanted flap anytime. When approaching the airfield, make sure to descend to around 400 m when you are approximately 2 km away from the start of the runway. This is an appropriate distance to decelerate. As the airstrip occupies 1/3 of your windscreen, reduce speed to approximately 220 km/h, deploy combat flaps and cancel out that extra lift by pitching down. When you are almost touching down, reduce speed to no more than 160 km/h (seems dangerously slow but it can still glide safely), deploy landing gear, take-off flaps and pitch down even more so the SB 2M remains overall parallel to the ground. At the last second before touch down, make sure you are around 130 km/h and deploy landing flaps. This way the bomber can land gently and softly, and will not bounce off. At last, do not constantly hold the brake. Release brake immediately once the nose starts to dip down to avoid propeller strike.
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 machine gun (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 machine gun 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
- 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
- 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.

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.
