The He 112 B-0 represents the most advanced He 112 variant in the game (after the [[He 112 V-5]] and cannon-armed [[He 112 A-0]]). Given all advantages and disadvantages, He 112 B-0 is best played as a universal fighter. If encountering highly agile [[:Category:Biplanes|biplanes]], use the He 112's speed to outrun them. If encountering fast, but less agile monoplanes, use agility to out-turn them. And if faced with bombers, nothing shall hold the He 112 back, as the firepower can finish any bomber quickly. That said, He 112 B-0 can be a quite enjoyable fighter to play, and will serve as a trainer for its successor in the German research tree – the [[Bf 109 B-1/L]], the first version of the legendary Bf 109 fighter series.

It is reasonably fast for a [[:Category:First rank aircraft|rank I aircraft]], while not faster than the Russian [[LaGG-3-11|LaGG-3]] and [[Yak-7B|Yak]] fighters, or the American [[F2A-3|Buffalos]] and [[P-36G|Hawks]] – all of them common adversaries of the B-0. It is also quite agile for a monoplane, but will always be out-turned by biplanes or light Japanese fighters such as the [[A5M4]] or [[Ki-27 otsu|Ki-27]]. Its climb rate is not exactly stellar, but He 112 B-0 can handle surprisingly high speeds – a red line of 690 km/h is not bad for rank I fighter. While mediocre in manoeuvrability and performance, the strongest trait of this plane is clearly the armament, which is the same as on the [[Bf 109 E-3]] fighter.

The offensive weapons are equal to the [[Bf 109 E-3]] with one exception: the nose-mounted machine guns have half the ammo. While this seems to be a drawback for the He 112, it really is not. With 500 rounds per gun, the Heinkel will not run out of ammo any time soon and their effectiveness against ''Battle of Britain'' aircraft is limited.
+
'''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.
  
−
The [[MG 17 (7.92 mm)|MG 17's]] major advantage comes in handy for adjusting shots at long range. The 7.92 mm bullet has better bullet ballistics than the [[MG FF (20 mm)|20 mm MG FF]], but they can still be used for predicting the bullet drop of the 20 mm cannon shells. Keep in mind that the MG 17's successor, the 13 mm [[MG 131 (13 mm)|MG 131]], has the ''same'' ballistics as the MG 17; a decision made in real life to allow pilots to immediately use the new MG without having to adjust for a change bullet behaviour.
+
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.
  
−
On paper, the He 112 B-0 appears to be quite well armed, having two machine guns and two MG FF cannons. However, the cannons are quite underwhelming, especially with the ''Air targets'' belt. Many of the belts rounds seem to explode on the surface of enemy aircraft, damaging external features such as control surfaces, but doing very little internal damage. Sometimes, multiple hits can be placed on an aircraft with little or no effect. It is best to aim for flaps, particularly ailerons and elevators. This means that if an aircraft can't be knocked out of the sky, it can be forced to crash due to loss of control.
+
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.
  
−
The He 112 B-0 suits naval battles, especially naval RBs. Compared to other early German aircraft which have poor-penetrating 7.92mm machine guns, the He 112 B-0 has two powerful cannons which can deal a lot of damage, especially to small boats. The stealth belt suits this method best, as this belt has lots of APHE shots.
+
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.

In 1934, Heinkel Flugzeugwerke company started work on a fighter to participate in the competition created by German Reichsluftministerium (RLM) in order to find a modern fighter aircraft for future needs. The largest portion of inspiration was drawn from the Heinkel He-70 "Blitz", a passenger and postal plane. This plane designed by the Günther brothers and introduced in 1933 was quite modern for its time, as it featured an all-metal monocoque fuselage, retractable landing gear and elliptical wings with a reverse gull-wing shape.
 
−
 
 
−
The He-70 Blitz could reach speeds up to 360 km/h (224 mph) and indeed the name means "Lightning" in German, so it was close to the minimum speed demanded by RLM on its own. This made the He 70 a great basis for a new fighter, and designers thus proceeded with modifying the He 70. The resulting design, called the He 112, was basically a down-scaled He 70, as it shared the all-metal construction, inverted gull wings and retractable landing gear. The first prototype, fitted with a British Rolls-Royce Kestrel Mk.IIS inline engine and designated He 112 V1, was completed in September 1935, followed by the He 112 V-2 powered by a Jumo 210C engine and incorporating some structural changes such as clipped wings and a three-bladed propeller, and finally by the He 112 V3, featuring a fully enclosed cockpit.
 
−
 
 
−
After the aircraft of Arado and Focke-Wulf were disqualified from the contest due to unsatisfactory performance, the competition had to be settled between the He 112 and Messerschmitt's Bf 109, designed by Willy Messerschmitt. Unfortunately for Heinkel, the Bf 109 emerged victoriously. The He 112 was more agile, but the Bf 109 was faster, had a better roll rate, and was cheaper and easier to manufacture. However, the development of the He 112 continued despite this defeat, and the plane was offered for export. Prototypes and small-scale production models were further developed up until its final and most advanced variant, the He 112 B.
 
−
 
 
−
The first version of the B-series and topic of this article was designated He 112 B-0. It featured a reworked fuselage, a new design of rudder and vertical stabiliser, and a bubble canopy, which was a very modern solution for its time. It offered superb visibility compared to "greenhouse" framed designs common in that time. The engine used was a Jumo 210C, producing 631 horsepower. Regarding armament, the He 112 B-0 was armed by two 7.92 mm MG 17 machine guns, mounted on the sides of the engine cowling, and two 20 mm drum-fed MG FF cannons, housed in the wings.

The first customer was the Empire of Japan, ordering of 30 He 112 B in 1938. The aircraft were however not used in combat due to their insufficient agility (compared to Japanese fighters) and ended their short career as trainers. Twelve He 112 B’s were sent to Spain, where they were used operationally in small numbers during the last weeks of the Spanish Civil War, and remained in service after the war ended. Notable usage passed the Civil War in Spain was from the 3rd of March 1943, when a single He 112 B managed to damage an American Lockheed [[P-38G-1|P-38 Lightning]] fighter. Spain eventually used its He 112's up until the 1950s. The two largest operators of the He 112 were Hungary and Romania – [[He 112 B-1/U2]] and [[He 112 B-2/U2]] both in their respective markings of the two countries are available in War Thunder as premium planes. Hungarian He 112's saw limited service and probably all of them were destroyed during the Allied bombing raids in 1944, while Romanian Heinkels saw some limited air combat in the opening stages of Operation Barbarossa, where they were used for ground attack missions and ended their career as training planes.

Heinkel He 112 B-0 single-engine front-line fighter (He 112V9 prototype)
+
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.
−
 
 
−
Ernst Heinkel continued to improve his fighter. The He 112 was drastically redesigned. It was actually a new aircraft, although the former designation was retained. The He 112 V9 prototype, which later became the main aircraft of the He 112 B-0 preproduction batch, even differed from its predecessors in external appearance. Its wingspan was reduced and its total fuselage length increased. The shape of the tailplane and the fin was completely changed, and the rudder area was noticeably enlarged. A bubble canopy was installed in the rear section of the cockpit instead of the fuselage spine fairing, and the cockpit itself obtained a sliding section and became completely closable.
 
−
 
 
−
The He 112 B-0 had a Junkers Jumo 210C twelve-cylinder in-line liquid-cooled engine producing 680 hp takeoff power and featuring a Junkers-Hamilton two-bladed variable-pitch metal propeller.
 
−
 
 
−
The He 112 B-0's armament was exceptionally powerful for its time and included two synchronous 7.92 mm Rheinmetall-Borsig MG 17 machine guns mounted on either side of the forward fuselage, with 500 rounds of ammunition each, and two 20 mm Oerlikon MG FF cannons mounted in the wing panels, with 60 rounds each.
 
  
−
With all performance characteristics considered, the He 112 B-0 looked better than the Bf 109's early versions. But the Messerschmitt had already been launched into full-scale production by that time, and it was cheaper, simpler, and easier to produce than the He 112. Besides, the Bf 109 was more versatile, and its design had significant potential for further improvement.
+
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.
  
−
Heinkel realized that the He 112 would probably never be accepted for service with the Luftwaffe, so he put special emphasis on obtaining export orders for his fighter. Japan was the first to take an interest in the He 112. In early 1938, four fighters of the He 112 B-0 variant were added to the arsenal of the Imperial Japanese Navy. A total of 12 He 112 B-0 machines were delivered to Japan during the coming years. These aircraft, unlike the first He 112 A-0 preproduction machines, were accepted for service with the Navy under the same designation, the A7He1 Carrier Fighter, but they never participated in any combat operations and were mainly in service with training units.
+
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.
  
−
26 machines of a He 112 B-0 preproduction batch commandeered from the "Japanese Order" were used temporarily by the Luftwaffe. In 1938, all of them were part of the 3rd and the 4th squadrons of the JG 132 Fighter Wing and provided air cover over Leipzig during the Sudeten Crisis of 1938.
+
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.
  
−
17 aircraft of the He 112 B-0 variant were delivered to Spain, where they formed a separate fighter wing called Grupa de Casa 5-G-5. The Spanish operated their He 112s until the early 1950s.
+
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.
  
−
A total of 34 machines of the He 112 B-0 series were produced, including 4 prototypes and 30 production aircraft.
+
From December 1939 on, all SB bombers were equipped with VISh-22 three-bladed, controllable-pitch propellers.

  • 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 big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/ historical reference" (example: https://wiki.warthunder.com/Name-vehicles/historical reference) and add a link to it here using the main template. Be sure to include links to sources at the end of the article.

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"".

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.
