Description

The SB 2M-100 is a rank I Russian bomber with a battle rating of 1.3 (AB), 1.0 (RB), and 1.7 (SB). It has been in the game since the start of the Open Beta Test prior to Update 1.27.

General info

Flight Performance

The SB 2M-100 is a light bomber, and therefore is a bit more manoeuvrable than some other bombers that it might encounter, such as the PBY, B-10B, and Do 17.

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

The SB 2M-100 can be outfitted with the following ordnance:

• 6 x 100 kg FAB-100 bombs (600 kg total)
• 2 x 250 kg FAB-250M43 bombs (500 kg total)
• 1 x 500 kg FAB-500 bomb (500 kg total)

Defensive armament

The SB 2M-100 is defended by:

• 2 x 7.62 mm ShKAS machine gun, nose turret (950 rpg = 1,900 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

Describe the tactics of playing in an aircraft, the features of using vehicles in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons

Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: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

A three-seat, all-metal monoplane with a retractable landing gear system including a tail wheel.

This aircraft was designed in the Department of Aviation, Hydroaviation and Aircraft Prototype Engineering (AGOS) of the Central Aerohydrodynamic Institute (TsAGI) under the direction of A. N. Tupolev and A. A. Arkhangelski. A prototype ANT-40-1 made its first flight on 7 October 1934. Full-scale production of the aircraft under the designation of SB (meaning "High-Speed Bomber") was launched in February 1936.

When creating the new aircraft, the designers paid much attention to the plane's aerodynamic superiority, considering this one of the most important components necessary to obtain high speed. Many structural and technological decisions were made to improve the plane's aerodynamics. It was the first time that an aircraft of this class had smooth metal skin instead of more rigid, corrugated skin; also, new high-strength materials were introduced, flush riveting used, retractable landing gear installed, and crew cockpits enclosed. The SB included the most advanced achievements in the field of aerodynamics, aircraft materials, and technology. As a result, during tests, the ANT-40 prototype nearly matched the maximum speed of the I-16 fighter.

The first production SB planes had 750 hp Klimov М-100 twelve-cylinder, V-type, liquid-cooled engines (a licensed version of the French Hispano-Suiza 12Ybrs engine).

The engines were fitted with cowls featuring a frontal circular radiator which was completely covered by movable shutters which regulated the incoming air flow. The first production SBs were equipped with two-bladed, fixed-pitch metal propellers.

The SB's defensive armament included three gun posts: a starboard post, an upper post, and a hatch post. The starboard mount in the navigator's cockpit consisted of two 7.62 mm ShKAS machine guns with a total magazine capacity of 1,900 rounds. The TUR-9 upper turret was equipped with one ShKAS machine gun whose magazine capacity was 1,000 rounds. The LU hatch mount, with one ShKAS machine gun carrying 500 rounds, was intended for cover the aircraft's lower rear. All of the machine guns were belt-fed, which was also was a revolutionary innovation: the rest of the world mostly continued to use detachable magazines.

The bombing armament of the first-series SBs was housed only inside the bomb bay, on two DER-33 horizontal racks (on which FAB-500 or FAB-250 bombs could be suspended) or four DER-34 vertical racks (for FAB-100 bombs or bomb clusters). The plane's maximum bomb capacity was 600 kg (6 FAB-100 bombs, suspended vertically).
