The M3 Stuart was a comprehensive upgrade of the earlier M2 light tank. It featured a new Continental petrol engine - more powerful than on the preceding M2, a new vertical volute suspension system (VVSS), an M5 37 mm main gun (later replaced by the M6 37 mm gun) with a new recoil system. The secondary armament consisted of up to 5 .30 cal (7.62 mm) M1919 machine guns. One was coaxial to the main gun, one was ball-mounted in the hull front, two were mounted in sponsons in the hull, and one was located on an anti-aircraft mounting on the turret. Often, the two sponson-mounted machine guns would be removed by the crew to save space and reduce weight. The M3 was manned by a crew of four: driver, co-driver, commander, and gunner.
 
−
 
 
−
The main armor composition was of face-hardened rolled homogeneous armor. The sides and rear of the hull and turret were 1 inch (25.4 mm) thick. The turret front was 38.1 mm thick, and so was the gun mantlet. The hull lower glacis was 44.4 mm thick, and the angled upper glacis was 15.8 mm thick and angled at 70 degrees. The upper front plate was 38.1 mm thick and angled at 18 degrees. The turret and hull roofs were 12.7 mm thick.

−
==== M3 Stuart (Stuart Mk I/II) ====
 
−
The M3 was the first production model of the series, and it was introduced in March of 1941. 5811 M3 Stuarts were built and they were called the Stuart Mk I in British service. 1285 of those were built with Guiberson diesel engines and were designated as Stuart Mk II by the British. The diesel engine Stuarts were built to British specification, not for American service. The British often referred to the Stuarts as the Honey tank, because of how smooth the ride was. A turret basket was added for the commander and gunner to sit in. Many of the original M3 Stuarts were sent to Britain under the Lend-Lease Act.
 
−
 
 
−
==== M3A1 Stuart (Stuart Mk III/IV) ====
 
−
Introduced in 1942, the M3A1 featured an improved turret. The new turret featured a turret basket and a different AA machine gun mount. Additionally, all of the sponson-mounted machine guns were removed on the M3A1 version. This left only three .30 cal (7.62 mm) machine guns; one hull-mounted, one AA mounted, and one coaxial. Additionally, the vertical stabilizer for the gun was improved. 4621 M3A1 Stuarts were produced, and production ended in February 1943. The M3A1 was exported to the British as the Stuart Mk III, and the diesel version was called the Stuart Mk IV in British service.
 
−
 
 
−
==== M3A3 Stuart (Stuart Mk V) ====
 
−
The M3A3 variant featured sloped frontal armor very similar to that of the M5 Stuart. The new armor arrangement was easier to produce and it also offered better protection. As a side effect, the M3A3 hull was heavier than the earlier version; the hull also had increased volume, which allowed for more fuel and ammunition storage. The M3A3 also introduced an improved turret with a larger bustle on the rear for the storage of a SCR 508 radio. Because of the increased space inside the hull, the ammunition storage was increased to 174 37 mm rounds and 7500 7.62 mm rounds. 3427 M3A3s were produced, with production ending in October 1943. In British service they were called Stuart Mk V.

== Service ==

−
13,800 M3 Stuarts were used in all the theaters of World War 2 with a number of different nations.

−
=== Variants ===
 
−
The M3 Stuart, the first production series, was not intended for fighting other tanks but instead was meant to fight infantry units. With an armament of five .30 cal machine guns and one 37 mm gun the M3 was quite capable of its job. The standard livery was khaki-olive paint with US identification markings. The turret was often painted with a white or yellow horizontal band, and some units also added unit markings. Extra tracks and fuel were often stored on the exterior of the tank, and the sponson machine guns were often removed to save space and weight.
 
−
 
 
−
The M3A1 was an improved version which was produced until 1942, when the M3A3 and M5 Stuart were introduced. During Operation Torch in 1942 the M3A1 was often painted olive drab with the standard US identification markings. The M3A1s were painted very similarly to the M3s, and American identification markings were made very large, as the French (who held West North Africa during Operation Torch) held no anti-American sentiment. Additionally, the M20 anti-aircraft mounting for a .30 cal machine gun became common during this campaign. Extra tracks and fuel were mounted just the same as on the M3. The M3 was heavily used by the British, and British Stuarts were often covered in extra supplies and equipment. British Stuarts were painted in straight line blue-sand livery, with pale green upper surfaces.
 
−
 
 
−
The M3A2 was an experimental design that was not produced.
 
−
 
 
−
The M3A3 was the final design of the series, as the M3 series was replaced by the M5 series. The M3A3 was built with the intention to simplify production without reducing the performance. The M3A3 featured a single sloped upper glacis and new turret. The M3 series was mostly replaced by the M24 Chaffee in the European Theater after the North African campaign, but they were used heavily in the Pacific theater as the Japanese tanks were easier to deal with.
 
−
 
 
−
=== Britain and the Commonwealth ===
 
−
The British found the Stuart to be much more reliable than the Crusader tanks they were also operating at the time. The Stuarts were put to good use in the North African campaign, but the protection was found to be lacking against contemporary German tanks and anti-tank guns. As such, the Stuart was not heavily used by the British in the European theater, but was instead shifted to the India-Burma theater in British and Australian units. The Japanese tanks they faced their were much easier targets for the Stuarts as they were much less armored and had less firepower. The British and Australians often converted their Stuarts to non-combat roles.
 
−
 
 
−
=== United States ===
 
−
In North Africa, the M3 Stuart was proven to be vulnerable to enemy anti-tank weapons whilst having an Armament that was seen as insufficient. As such, the Stuart was relegated to non-combat roles such as rearguard and reconnaissance. The M3 Stuart was mostly replaced by the M24 Chaffee in the European theater, but they saw significant service in the Pacific. In the European theater they were only used to support the more capable M4 Shermans and the crews of M3 Stuarts made sure to avoid frontal engagement of enemy armour.
 
−
 
 
−
The M3s in the Pacific did not see much armoured opposition and there was only one anti-tank gun that posed a major threat, the 45 mm gun of the Chi-Ha and its variants. The Japanese tanks they did face were mostly less capable than the M3, with less armor and firepower. The first tank on tank combat the M3 saw in the Pacific was in the Philippines in December of 1941. There, the 192nd and 194th Light Tank Battalions saw combat mostly against Japanese Ha-Go tanks.
 
−
 
 
−
=== Soviet Union ===
 
−
The Soviet Union received 1000 M3 Stuarts along with M3 Lees and M3 Half-tracks through the Lend-Lease Act. The M3 Stuarts delivered to the USSR were of differing variants. The USSR did not like the M3 Stuart. They believed the armor and firepower was inadequate, the tracks were not suited to Russian winters, and the fuel was too flammable. As such, the USSR turned down American proposals for the delivery of M5 Stuarts, and sent their M3s to the Manchurian front where they would face less armored opposition.

 +
'''Arcade Battles:'''
  
−
'''GMC M8A1'''
+
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.
  
−
'''81mm MMC T27'''
+
'''Realistic Battles:'''
  
−
'''81mm MMC T27E1'''
+
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.
  
−
'''T29 4.2in MMC'''
+
'''Simulator Battles:'''
  
−
'''CMC T81'''
+
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.
  
−
'''40mm GMC T65'''
+
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 dead zone, 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.
  
−
'''20mm MGMC T85'''
+
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 is 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.
  
−
'''M5 COM'''
+
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.
  
−
'''Reconnaissance Vehicle T8'''
+
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 kph, 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 kph (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 kph 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.
  
−
'''Reconnaissance Vehicle T8E1'''
+
'''Against the SB 2M (all modes but mostly in sim):'''
  
−
'''M5A1 (E5R1-M3) "Zippo"'''
+
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.
  
−
'''M5A1 (E7-7) "Zippo"'''
+
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.
  
−
'''M5A1 (E9-9) "Zippo"'''
+
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 it's 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.

−
'''Stuart Recce'''
+
* 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:'''
  
−
=== Brazilian ===
+
* 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 (Family)|Ki-61]]
−
'''X1A'''
+
* 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 (Family)|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 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.
  
−
=== Yugoslav Partisans ===
+
After testing was performed, the SB 2M-103 bomber was launched into full-scale production in 1938 under the designation of "96th series".
−
'''M3A1 (81 mm Mortar)'''
 
  
−
'''M3A1 (7.5 cm Pak 40)'''
+
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.
  
−
'''M3A3 (7.5 cm Pak 40)'''
+
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.

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

Main articles: FAB-100 (100 kg), FAB-250M43 (250 kg), FAB-500 (500 kg)

The SB 2M-103U MV-3 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)
  • 2 x 500 kg FAB-500 bombs + 2 x 250 kg FAB-250M43 bombs (1,500 kg total)
  • 3 x 500 kg FAB-500 bombs (1,500 kg total)
  • 2 x 250 kg FAB-250M43 bombs + 6 x 100 kg FAB-100 bombs (1,100 kg total)
  • 1 x 500 kg FAB-500 bomb + 2 x 250 kg FAB-250M43 bombs (1,000 kg total)
  • 4 x 250 kg FAB-250M43 bombs (1,000 kg total)

Defensive armament

Main article: ShKAS (7.62 mm)

The SB 2M-103U MV-3 is defended by:

  • 2 x 7.62 mm ShKAS machine gun, nose turret (1,920 rpg)
  • 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 dead zone, 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 is 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 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.

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 kph, 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 kph (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 kph 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 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 it's 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

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 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

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".

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.

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.

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.

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.

From December 1939 on, all SB bombers were equipped with VISh-22 three-bladed, controllable-pitch propellers.
