Survivability and armour

• No armour plating
• No armour glazing
• Critical components located at the front of aircraft (fuel, pilot, engine, controls)
• More fuel tanks located in wings near the fuselage

Usage in battles

The BB-1 is one of the best low-BR ground attackers available. It can take up to 12 50kg bombs, with 8 of these being carried on the wings and an additional 4 in the bomb bay. These 4 can be dropped individually instead of 2 at a time like the wing-mounted ones. The aircraft also has a bomb sight, which can be very useful for precise bombing and allows you to set a 0 second fuse as you don't have to get close enough to be injured by it. It can also fight other fighters, having decent performance and a good turn rate, as well as quite a lot of firepower.

This aircraft is an all-rounder, able to destroy almost all ground targets. It has a rear gunner, but it's usefulness is limited due to it's limited firepower combined with the plane's already good turn rate, making the plane able to turn-fight. It can still be used, however, and if you are lucky you might score a few extra ground hits with it once your ammo has run out.

• Very effective guns
• Large bombload
• Bomb bay
• Decent performance
• Has Bombsight
• Good maneuverability and responsive controls
• Has tail gunner

Cons:

In-game description

"OKB Sukhoi BB-1 (Su-2) ""Ivanov"" Short-Range Bomber with M-87 engine.

A single-engine, mixed-construction monoplane light bomber with retractable landing gear and tail wheel. This project was developed as an entry in the 1936 competition for the best high-speed long-range ground-attack reconnaissance plane, to be known as the ""Ivanov."" The design and construction were completed in a record time of 6 months. The first flight of the SZ-1 (SZ: ""Stalin's Mission""), with an M-62 engine, was made on August 25, 1937.

The prototype selected for mass production was the SZ-3, equipped with an M-87 engine. In March of 1939, even before government tests were completed, the ""Ivanov"" airplane (with the M-87A engine) was accepted by the Red Army Air Force. It entered mass production under the designation BB-1 (short-range bomber one).

Unlike the prototypes, the production model had a mixed construction. The fuselage was a wooden monocoque with plywood paneling, and the wings and stabilizer were metal. This choice was made because, due to the many all-metal aircraft in the USSR at the time, metal was in short supply.

The first production aircraft were fitted with air-cooled radial 14-cylinder OKB Tumansky M-87 engines, rated at 950 hp. The aircraft's armament included a battery of 4 fixed ShKAS 7.62mm machine guns with 850 rounds each, mounted in pairs on each wing. To protect the aircraft's rear, the navigator had a rotating MB-5 turret with another 7.62mm machine gun with 900 rounds of ammunition. The prototypes had a ventral MB-2 turret with a ShKAS machine gun, but this was removed as it seemed unlikely that any enemy fighter attacks would come from below when the plane was flying at a low altitude. However, it was soon shown that this was a poor decision, as such attacks were frequent in actual combat.

The plane's usual bomb load, when flying at its maximum range, was 400 kilograms. Overweight capacity was up to 600 kilograms. The maximum bomb load was 1200 kilograms. Bombs of up to 100 kilograms could be placed both in the internal bomb bay and suspended under the outer wings. KD-1 or KD-2 bomb racks were used to carry and drop these bombs. Rockets were not carried."
