The '''{{Specs|name}}''' is a rank {{Specs|rank}} American medium tank {{Battle-rating}}. It was one of the first American tanks to be released with the American ground tree in [[Update 1.45 "Steel Generals"]]. As an upgraded version of the [[M26|M26 Pershing]], it features many similarities to its predecessors but is improved with a better gun and engine for increased firepower and mobility.
+
The end of World War II left the US Army in a state of demobilization, with budget cuts interfering with many of the US Army's projects, including those aiming to continually improve the tank fleet that began seeing the [[M26|M26 Pershing]] put into the service. Without the funds for a major overhaul, it was decided to modernize their existing M26s in 1946. The first prototype was created in 1948, with the project large enough that by its acceptance it was designated the M46. The M46 would see itself put into action sooner than expected with the outbreak of the Korean War in 1950, where it served alongside its predecessors against Korean and Chinese troops. By the end of the war, with newer tanks like the [[M47]] coming into service, the M46 was retired from US service but continued to serve for a few more years as foreign aid.

 +
The '''{{Specs|name}}''', introduced with the American ground tree in [[Update 1.45 "Steel Generals"]], is an improved version of the M26 Pershing. The two biggest shortcomings of the M26, the mobility and firepower, have been improved on to allow a better player experience with the tank. The M46 can stand up against most enemies it faces with the improved firepower of the HEAT-FS shell, but should take care that the enemy doesn't get the first shot off as the armour remains the same otherwise.

The tank plays almost like the M26 Pershing, it's relatively fast for its size yet has a very powerful gun. In comparison, the M46 Patton features improved manoeuvrability with increased acceleration, it also has a better gun to combat the foes it will face at its rank. Due to this, the M46 Patton can fit into multiple roles like the Pershing as an offensive or supporting unit. Attack and flank enemy units with the cooperation of allied units to get their more vulnerable sides.

At this rank, the more heavy duty vehicles appears such as the [[IS-3]], [[Tiger II (10.5 cm Kw.K)|10.5cm Tiger II]], [[T32|T32]], and the [[Maus|Maus]]. These tanks are a menace to not just you, but possibly your entire team. Taking these tanks out in the M46 Patton require close cooperation with other allies in order to get around and hit them in their side armour. More powerful ammunition unlocked in later modifications may improve your attempts at destroying these beasts.

The M46 plays like a light tank in Arcade, because it can reach speeds over 50 km/h in perfect conditions. Furthermore, it's very agile - turning on the spot and maneuvering in close quarters is extremely easy. Altogether, this tank is a pleasure to play in cities in Arcade, because you can escape stand-offs and flank the enemy tank, or you may decide to bait a shot by showing your side, then instantly reversing, or you might want to just leave the encounter altogether and help out a teammate who is relatively nearby. Oh, and your agility can also help you bounce shots - just move your hull and turret around slightly if you think you will get shot.

Oh, and your agility can also help you bounce shots - just move your hull and turret around slightly if you think you will get shot.
 
 
However, the agility of the tank comes at a cost - the armour is non-existent. At 7.0 Battle Rating all tanks can penetrate you anywhere. Luckily, though, this tank usually gets down-tiered to 6.7, although 7.7 is also frequent. Overall - try not to get shot, because you're likely to be very crippled, or dead, in one-shot. If you survive, however, there's a high chance that you can either shoot back, or use your mobility to get into cover, or just run away.
 
  
Lastly, in Arcade, your gun is very effective. Use HEAT-FS rounds and the markers to try to hit as many different enemies as possible - don't try to finish them off, just go for assists. Your round is almost guaranteed to penetrate wherever you hit, and if you don't hit ammunition and one-shot a tank, you are likely to take out a crew member or two, some vital component (e.g. the gun, the transmission, the engine etc.), making it very easy for your teammates to clean-up. It is unfortunate, however, that you don't get a stabilizer, so caution has to be taken when peeking corners or driving around flanks.

''Very importantly'', however, you ''must'' always move around the map. In Arcade, enemies often try to focus on a single tank that is slow, or not moving, and if you can move around the map - many enemies will forget about you, or think that their teammates will cover them. Just move around, and try not to get shot!

The M46 is not as effective in Realistic, due to much slower and focused gameplay, in the sense that a spotted vehicle is often a dead vehicle. The lack of armour doesn't help you here, either, because players take longer to aim at you, reducing any chances of lucky ricochets, and most rounds will be able to penetrate the anywhere.

If you can't rely on armour, mobility comes into question, and in Realistic it is dampened. Here, the behaves much more like a general medium tank, like the Centurion or the T-34. You are mobile, and quick, but you won't be able to run away from encounters, or flank an enemy in seconds (like you can do in Arcade). Therefore, you should play much more carefully, and avoid being seen at all, which can be easily accomplished because you can still maneuver rather easily in close quarters.

In terms of gunpower, it's still very reliable, penetration-wise. However, in Realistic it is advised to take your time to learn enemy vehicles and their ammo racks, because you would want to one-shot most of your enemies (if you don't, it's harder to escape from return shots). Hence why it's advised to flank your enemies and take your time, instead of running around the map like one might do in Arcade. Luckily, HEAT-FS does tend to explode ammo racks.
+
In terms of firepower, it's still very reliable, penetration-wise. However, in Realistic it is advised to take your time to learn to identify enemy vehicles and their ammo racks, because you would want to take out enemies with a single shell (if you don't, it's harder to escape from retaliatory shots). Hence why it's advised to flank your enemies and take your time, instead of running around the map like one might do in Arcade. The HEATFS shell has a tendency to cause ammo racks detonations. Also carry some APHE shells, as more often than not, HEATFS shells have a tendency to be a bit unreliable. Even when uptiered, the M46's APHE can deal devastating blows on the enemy's armour, if you know where to aim.
  
 
In general, in Realistic, just play calm and try to create a false sense of security for the enemies. Instead of tackling someone head-on, you should retreat and let them move into your ambush, because you don't have a stabilizer, nor armour.

===M26 Pershing Modernization===
The '''M46 Patton''' came about around the time of the Korean War. Before that, the US Army armoured units consisted of two tanks, the venerable [[M4A3 (76) W|M4 Shermans]] and the newer [[M26|M26 Pershings]]. Of the two, the Pershing was originally classified as a heavy tank as it weighed 41.7 tons compared to Sherman's 30-ton weight, but a reorganization had the M26 Pershing classified a medium tank after World War II. It proved unsuitable for the role as its mobility was unsatisfactory for that role, using the same Sherman engine, plus an unreliable transmission, to propel a vehicle ten tons heavier.
+
[[File:M26_Ready_for_Inspection.jpg|right|thumb|x300px|none|A M26 Pershing awaiting inspection in Germany.]]
 +
At the end of World War II, the US Army's most modern tank design was the [[M26|M26 Pershing]] heavy tank. The M26 was remarkably better than the [[M4A3 (76) W|M4A3 (76) W HVSS Sherman tank]] in terms of armour and gun, but was deficient in engine power as it was around ten tons heavier than the M4A3, but retained the same 500 horsepower Ford engine.<ref name="Hunnicutt_1984(9-17)">Hunnicutt 1984, 9-17</ref> When tank production was halted in October 1945, the US Army had 2,212 M26s in inventory.<ref name="Zaloga_2000(35)">Zaloga 2000, 35-42</ref> As the US Army reorganized and specified their needs for the post war period, which included the reclassification of the M26 from a heavy tank to a medium tank in May 1946,<ref name="Zaloga_2000(35)"/> the US Army sought the procurement of new tanks to make up the post-war tank fleet. However, the demilitarization and budget cuts with World War II's end heavily constrained the US Army's tank development and procurement programs. Stuck with what they had, the US Army began looking into modernizing the M26s to turn them into their desired postwar tank.<ref name="Hunnicutt_1984(9-17)"/>
 +
 
 +
The ''M26E2'' modernization program began in January 1948.<ref name="Zaloga_2000(35)"/> As the engine was the biggest issue with the M26 Pershing, it and the transmission became the primary focus of the modernization program. Continental Motors Corporation, which was developing an engine specified by Ordnance Committee and the Tank Engine Committee since 22 July 1943, produced the AV-1790-1 engine that has significantly more horsepower than the Ford engine. Continental's AV-1790-1 engine was chosen to become part of the modernization program. The transmission was upgraded to a General Motors (GM) CD-850-1 cross drive design, a transmission design that was considered for US tank designs as far back in April 1943 during trials with the [[T20]] tank.<ref name="Hunnicutt_1971(58)">Hunnicutt 1971, 58</ref> The cross drive transmission was beneficial as it was almost twice as short as the original M26 transmission, yet is able to perform the function of a transmission, steering control, and vehicle brake.<ref name="Hunnicutt_1971(154-156)">Hunnicutt 1971, 154-156</ref> Firepower improvements was also considered, with the [[T54 (90 mm)|90 mm T54]] gun as a possible upgrade option. However, this was cancelled as the 90 mm T54 introduced a new type of ammunition into the logistics train, and focus was put into improving the current [[M3 (90 mm)|90 mm M3]] in the M26. This became upgraded into the [[M3A1 (90 mm)|90 mm M3A1]] which saw the addition of a bore evacuator and a new single-baffle muzzle brake design.<ref name="Zaloga_2000(35)"/>

[[File:T40 (M46) at Fort Knox.png|x300px|left|thumb|none|A T40 medium tank prototype at Fort Knox. This vehicle is serial number #4.]]
 +
By May 1948, a complete M26E2 tank (registration number 3012420) was completed and shipped to the Aberdeen Proving Grounds.<ref name="Hunnicutt_1971(154-156)"/> Technical issues led to further improvements in the tank's components. In fiscal year 1948, the US authorized ten M26E2 tanks, with the program now designated as the medium tank ''T40''. Changes were made to the M26 chassis for the modernization, most notably the additions of mufflers on the top of each side's fender for the engine exhaust pipes and a small track tension idler wheel between the rear sprocket and the rear road wheel. By 30 July 1948, the Ordnance Technical Committee Minutes (OTCM or OCM) 32312 designated the T40 tanks as the '''M46''' medium tank, with the nickname "General Patton" after General George S. Patton. A production run of 800 tanks was authorized in 1949 fiscal year, with the hopes of 1,215 M26 tanks being converted to M46 standards in the 1950 fiscal year. The first M46 would roll off the production lines in November 1949, now powered by a Continental AV-1790-5A with a GM CD-850-3 transmission.<ref name="Hunnicutt_1984(9-17)"/>

===Korean War Breaks Out===

[[File:USMC M-46 Patton Medium Tank in 1952.jpg|x350px|right|thumb|none|A M46 moves down a hill with its turret traversed over the engine deck. Here the distinctive engine exhausts and mufflers can be seen on the M46's fenders on both sides.]]
 +
As the US Army began ramping up production and conversion programs for the M46 tank, the Korean War began in June 1950. The Korean War's demand for armour caused tanks in all US Army depots and stockpiles to be reactivated and sent to the Korean peninsula. This unfortunately means that the M26 Pershing tanks meant to be converted to M46s were limited. The M46, of which only 319 units were produced by the Korean War's outbreak,<ref name="Zaloga_2000(35)"/> fell into a quagmire within the US Army of not having enough M26s available to convert, but being outdated enough to not warrant the production of new units. In an effort to get new, modern tanks ready as quick as possible, it was suggested in July 1950 that the turret of an ongoing medium tank development, the ''T42'', be placed onto the M46 hull<ref name="Hunnicutt_1984(9-17)"/> A pilot model was produced and shipped to Aberdeen Proving Ground on March 1951, designated ''M46E1''.<ref name="Hunnicutt_1984(52-53)">Hunnicutt 1984, 52-53</ref> Following further modifications, this combination would culminate into the [[M47]] tank.
 +
 
 +
Continued field testing with the M46 and the development of the T42 led to more improvements in the M46 design. Initially designated the "M46(New)", this new improvement included a more efficient oil cooling system, new instrument panel, new hull wiring, improved brakes, and a new fire extinguishing system. A new Continental AV-1790-5B and General Motors CD-850-4 transmission was also designed that was interchangeable between the improved M46 and the T42. The "M46(New)" was eventually redesignated to ''M46A1'' when it went into production with a contract for 360 units in 01 April 1951.<ref name="Hunnicutt_1984(9-17)"/> These M46A1 tanks started production from registration numbers 30163849 and up.<ref name="Zaloga_2000(35)"/>

As the Korean War demanded large numbers of tanks, the M46 Pattons were sent alongside M4A3 Shermans and M26 Pershings into the fray. The first unit with M46 tanks in Korea was the 6th Tank Battalion, which was unloaded into Pusan on 08 August 1950.<ref name="Hunnicutt_1984(25-30)">Hunnicutt 1984, 25-30</ref> The 6th Tank Battalion was soon followed by the 64th Tank Battalion on August 13th that was also equipped with M46s.<ref name="Pike_2021">Pike 2021</ref> Of the 1,326 American tanks sent to Korea, 200 were M46 Pattons while the rest were 309 M26 Pershings, 679 M4A3 (76) W HVSS Shermans and 138 M24 Chaffees.<ref name="Zaloga_2000(35)"/>
  
Work began in January 1948 to upgrade the Pershing's mobility with a new engine and transmission. The project was initially designated the ''M26E2'', but as newer upgrades and more modifications are installed onto the tank, it began to feel more like a completely new design rather than a Pershing upgrade, so it was decided to give the model a completely new designation. The end result was the Pershing tank mounting the mentioned upgrades, plus a new power plant and gun with a bore evacuator to expunge propellant fumes. This model was designated the '''M46 Patton''', named after General George S. Patton, the commander of the US Third Army and played a role in the establishment of American tank forces. The rebuilding of the tanks began in November 1949 and had 1,160 Pershings rebuilt into M46s, 800 to the standard variant and 360 to the ''M46A1'', which had better brakes, a cooling and fire protection system, a new engine and transmission, and better electrical equipment.
+
The M46s benefitted from the more powerful powertrain to be more manoeuvrable than the M26 Pershing in the theater. However, the rapid development and fielding of the M46 showed technical problems in the field, with breakdowns associated to problems with components like the engine oil cooler fan.<ref name="Connor_1992 (73)">Connor 1992, 73</ref> Nevertheless, the M46s were used effectively before and after the Chinese became involved with the Korean War, with 97 M46s in the Eight Army being involved with the January 1951 counter-offensive against the Chinese.<ref name="Zaloga_2000(35)"/> One feature that was tested with the M46 Pattons was the attachment of a searchlight onto the tank to have better battlefield illumination for night battles. The original idea called for taking a M4A3 Sherman tank to be designed with a special turret accommodating a searchlight and a 75 mm gun, designated the ''T52'' searchlight tank. An alternative solution was devised by attaching searchlights atop tank cannons, which proved to be cheap enough to not warrant a new tank design and convenient enough for any tank to be equipped with a searchlight.<ref name="Hunnicutt_1984(25-30)"/>

===Combat usage===
+
The Korean War would end in a ceasefire brought about by an armistice. Due to the armistice dictating the restrictions of weapon imports into the region, the M46s continued to serve there in American hands as America developed their newer tank models. By 14 February 1957, OTCM 36468 would declare the M46 and M46A1 as obsolete, with the Americans only using the M46 in Korea until they are retired from lack of spare parts.<ref name="Hunnicutt_1984(25-30)"/>
The M46 saw combat only during the Korean War. The first batch arrived on August 8, 1950, to the 6th Tank Battalion and proved superior to the North Korean and Chinese [[T-34-85]]s. About 200 M46 Pattons arrive in Korea by the end of 1950, making up 15% of the American armoured strength, though the majority was still the M4 Shermans. By 1951, all M26 Pershings in Korea were withdrawn and replaced by the M46 Pattons, and eventually, the units with Shermans were also re-equipped with the newer tanks as well. When the armistice was finally made, ending the conflict in the Korean Peninsula, the M46 Pattons were withdrawn back to the state.
 
  
By the later parts of the 1950s, the M46 Pattons in American service still were being replaced by the newer [[M47|M47 Pattons]] and those still in the inventory were leased for no cost to Belgium, France, and Italy for training purposes, sending American instructors to train the European crews and maintenance personnel.
+
After the end of the Korean War, the M46 became part of America's weapon exports to Europe. However, as America's tank productions churn out the M47 Patton II tank, the value of the M26 and M46 for combat-ready units was not high. The M26 and M46 tanks would be exported as training vehicles to prepare crew for the receiving of M47s. Though France, Belgium, and Italy received M26s for this role, Belgium would also receive eight M46A1 that were used as training vehicles at Leopoldsburg tank training center.<ref name="Zaloga_2000(35)"/> Many more M46s would find themselves as range targets.<ref name="Pike_2021"/>

{{break}}
The M26, which appeared close to the end of World War II, was an excellent tank. However, power-to-weight ratio, maneuverability, and range were lacking. A special new 12-cylinder, air-cooled engine developed by Continental Motors to take care of the maneuverability issue reached 29,361 cm³, and at 2,800 rpm its 704 hp outstripped the M26's 500 hp. The 6.5-fold compression, which was large for the time, required 80 octane fuel, and the air-cooling system often overheated the engine. Giving the tank a new power plant required a replacement roof for the compartment housing the engine and transmission, resulting in the use of a single grating.

The new automatic CD-850 gearbox and steering mechanism were operated using a single lever that served both as a gearshift and steering wheel. The M46's running gear gained another small roller to keep constant tension on the tracks and prevent them from slipping between the leading wheels and rear road wheels. In addition, the front suspension points were given second shock absorbers. The tank was built for low temperatures and had water-crossing special equipment. As a result, it was heavier, though it did not suffer from reduced speed thanks to its upgraded power plant.

Description

The end of World War II left the US Army in a state of demobilization, with budget cuts interfering with many of the US Army's projects, including those aiming to continually improve the tank fleet that began seeing the M26 Pershing put into the service. Without the funds for a major overhaul, it was decided to modernize their existing M26s in 1946. The first prototype was created in 1948, with the project large enough that by its acceptance it was designated the M46. The M46 would see itself put into action sooner than expected with the outbreak of the Korean War in 1950, where it served alongside its predecessors against Korean and Chinese troops. By the end of the war, with newer tanks like the M47 coming into service, the M46 was retired from US service but continued to serve for a few more years as foreign aid.

The Medium Tank M46 Patton, introduced with the American ground tree in Update 1.45 "Steel Generals", is an improved version of the M26 Pershing. The two biggest shortcomings of the M26, the mobility and firepower, have been improved on to allow a better player experience with the tank. The M46 can stand up against most enemies it faces with the improved firepower of the HEAT-FS shell, but should take care that the enemy doesn't get the first shot off as the armour remains the same otherwise.

Get "Parts" and "FPE" like the usual routine to increase the tank's survivability. After that, work towards the APCR and especially the HEATFS round at the Rank III and IV modifications to boost your firepower against enemies.

Notes:

  • As they are modeled by sets of 2, shells disappear from the rack only after you fire both shells in the set.
  • Rack 3 is a first stage ammo rack. It totals 10 shells and gets filled first when loading up the tank.
  • This rack is also emptied early: the rack depletion order at full capacity is: 3 - 1 - 2.
  • Simply not firing when the gun is loaded will move ammo from racks 1 and 2 into rack 3. Firing will interrupt the restocking of the ready racks.

Usage in battles

The tank plays almost like the M26 Pershing, it's relatively fast for its size yet has a very powerful gun. In comparison, the M46 Patton features improved manoeuvrability with increased acceleration, it also has a better gun to combat the foes it will face at its rank. Due to this, the M46 Patton can fit into multiple roles like the Pershing as an offensive or supporting unit. Attack and flank enemy units with the cooperation of allied units to get their more vulnerable sides.

At this rank, the more heavy duty vehicles appears such as the IS-3, 10.5cm Tiger II, T32, and the Maus. These tanks are a menace to not just you, but possibly your entire team. Taking these tanks out in the M46 Patton require close cooperation with other allies in order to get around and hit them in their side armour. More powerful ammunition unlocked in later modifications may improve your attempts at destroying these beasts.

Arcade Battles

The M46 plays like a light tank in Arcade, because it can reach speeds over 50 km/h in perfect conditions. Furthermore, it's very agile - turning on the spot and manoeuvring in close quarters is extremely easy. Altogether, this tank is a pleasure to play in cities in Arcade, because you can escape stand-offs and flank the enemy tank, or you may decide to bait a shot by showing your side, then instantly reversing, or you might want to just leave the encounter altogether and help out a teammate who is relatively nearby. Oh, and your agility can also help you bounce shots - just move your hull and turret around slightly if you think you will get shot.

However, the agility of the tank comes at a cost: the armour is non-existent. In the BR bracket all tanks can penetrate you anywhere. Try not to get shot at, because you're likely to be very crippled, or disabled, with a single shot.

Lastly, in Arcade, your gun is very effective. Use HEATFS rounds and the markers to try to hit as many different enemies as possible - don't try to finish them off, just go for assists. Your round is almost guaranteed to penetrate wherever you hit, and if you don't hit ammunition and take out a tank with a single shot, you are likely to take out a crew member or two, some vital component (e.g. the gun, the transmission, the engine etc.), making it very easy for your teammates to finish the enemy. You don't get a stabilizer, so caution has to be taken when peeking corners or driving around flanks.

Realistic Battles

The M46 is not as effective in Realistic, due to a much slower and focused gameplay, in the sense that a spotted vehicle is often a dead vehicle. The lack of armour doesn't help you here, either, because players take longer to aim at you, reducing any chances of lucky ricochets.

If you can't rely on armour, mobility comes into question, and in Realistic it is dampened. Here, the tank behaves much more like a general medium tank, like the Centurion or the T-34. You are mobile, and quick, but you won't be able to run away from encounters, or flank an enemy in seconds (like you can do in Arcade). Therefore, you should play much more carefully, and avoid being seen at all, which can be easily accomplished because you can still manoeuvre rather easily in close quarters.

In terms of firepower, it's still very reliable, penetration-wise. However, in Realistic it is advised to take your time to learn to identify enemy vehicles and their ammo racks, because you would want to take out enemies with a single shell (if you don't, it's harder to escape from retaliatory shots). Hence why it's advised to flank your enemies and take your time, instead of running around the map like one might do in Arcade. The HEATFS shell has a tendency to cause ammo racks detonations. Also carry some APHE shells, as more often than not, HEATFS shells have a tendency to be a bit unreliable. Even when uptiered, the M46's APHE can deal devastating blows on the enemy's armour, if you know where to aim.

In general, in Realistic, just play calm and try to create a false sense of security for the enemies. Instead of tackling someone head-on, you should retreat and let them move into your ambush, because you don't have a stabilizer, nor armour.

Pros and cons

Pros:

  • Powerful 90 mm main cannon, especially with HEATFS rounds
  • Great overall mobility
  • Low profile
  • Neutral steering
  • Rear mounted transmission
  • Excellent gun depression of -10 degrees
  • The additional armour (fence around turret) can fend off some HEAT and HESH shells, and even ATGMs

Cons:

  • Turret ring is prone to breaking
  • Elevation gear is slow
  • Armour can easily be pierced by other tanks at its rank
  • Struggles to penetrate many opponents from the front without HEATFS
  • Tendency to oversteer at high speeds in arcade battles due to high hp/ton ratio

History

M26 Pershing Modernization

At the end of World War II, the US Army's most modern tank design was the M26 Pershing heavy tank. The M26 was remarkably better than the M4A3 (76) W HVSS Sherman tank in terms of armour and gun, but was deficient in engine power as it was around ten tons heavier than the M4A3, but retained the same 500 horsepower Ford engine.[1] When tank production was halted in October 1945, the US Army had 2,212 M26s in inventory.[2] As the US Army reorganized and specified their needs for the post war period, which included the reclassification of the M26 from a heavy tank to a medium tank in May 1946,[2] the US Army sought the procurement of new tanks to make up the post-war tank fleet. However, the demilitarization and budget cuts with World War II's end heavily constrained the US Army's tank development and procurement programs. Stuck with what they had, the US Army began looking into modernizing the M26s to turn them into their desired postwar tank.[1]

The M26E2 modernization program began in January 1948.[2] As the engine was the biggest issue with the M26 Pershing, it and the transmission became the primary focus of the modernization program. Continental Motors Corporation, which was developing an engine specified by Ordnance Committee and the Tank Engine Committee since 22 July 1943, produced the AV-1790-1 engine that has significantly more horsepower than the Ford engine. Continental's AV-1790-1 engine was chosen to become part of the modernization program. The transmission was upgraded to a General Motors (GM) CD-850-1 cross drive design, a transmission design that was considered for US tank designs as far back in April 1943 during trials with the T20 tank.[3] The cross drive transmission was beneficial as it was almost twice as short as the original M26 transmission, yet is able to perform the function of a transmission, steering control, and vehicle brake.[4] Firepower improvements was also considered, with the 90 mm T54 gun as a possible upgrade option. However, this was cancelled as the 90 mm T54 introduced a new type of ammunition into the logistics train, and focus was put into improving the current 90 mm M3 in the M26. This became upgraded into the 90 mm M3A1 which saw the addition of a bore evacuator and a new single-baffle muzzle brake design.[2]

By May 1948, a complete M26E2 tank (registration number 3012420) was completed and shipped to the Aberdeen Proving Grounds.[4] Technical issues led to further improvements in the tank's components. In fiscal year 1948, the US authorized ten M26E2 tanks, with the program now designated as the medium tank T40. Changes were made to the M26 chassis for the modernization, most notably the additions of mufflers on the top of each side's fender for the engine exhaust pipes and a small track tension idler wheel between the rear sprocket and the rear road wheel. By 30 July 1948, the Ordnance Technical Committee Minutes (OTCM or OCM) 32312 designated the T40 tanks as the M46 medium tank, with the nickname "General Patton" after General George S. Patton. A production run of 800 tanks was authorized in 1949 fiscal year, with the hopes of 1,215 M26 tanks being converted to M46 standards in the 1950 fiscal year. The first M46 would roll off the production lines in November 1949, now powered by a Continental AV-1790-5A with a GM CD-850-3 transmission.[1]

Korean War Breaks Out

As the US Army began ramping up production and conversion programs for the M46 tank, the Korean War began in June 1950. The Korean War's demand for armour caused tanks in all US Army depots and stockpiles to be reactivated and sent to the Korean peninsula. This unfortunately means that the M26 Pershing tanks meant to be converted to M46s were limited. The M46, of which only 319 units were produced by the Korean War's outbreak,[2] fell into a quagmire within the US Army of not having enough M26s available to convert, but being outdated enough to not warrant the production of new units. In an effort to get new, modern tanks ready as quick as possible, it was suggested in July 1950 that the turret of an ongoing medium tank development, the T42, be placed onto the M46 hull[1] A pilot model was produced and shipped to Aberdeen Proving Ground on March 1951, designated M46E1.[5] Following further modifications, this combination would culminate into the M47 tank.

Continued field testing with the M46 and the development of the T42 led to more improvements in the M46 design. Initially designated the "M46(New)", this new improvement included a more efficient oil cooling system, new instrument panel, new hull wiring, improved brakes, and a new fire extinguishing system. A new Continental AV-1790-5B and General Motors CD-850-4 transmission was also designed that was interchangeable between the improved M46 and the T42. The "M46(New)" was eventually redesignated to M46A1 when it went into production with a contract for 360 units in 01 April 1951.[1] These M46A1 tanks started production from registration numbers 30163849 and up.[2]

M46 in Service

As the Korean War demanded large numbers of tanks, the M46 Pattons were sent alongside M4A3 Shermans and M26 Pershings into the fray. The first unit with M46 tanks in Korea was the 6th Tank Battalion, which was unloaded into Pusan on 08 August 1950.[6] The 6th Tank Battalion was soon followed by the 64th Tank Battalion on August 13th that was also equipped with M46s.[7] Of the 1,326 American tanks sent to Korea, 200 were M46 Pattons while the rest were 309 M26 Pershings, 679 M4A3 (76) W HVSS Shermans and 138 M24 Chaffees.[2]

The M46s benefitted from the more powerful powertrain to be more manoeuvrable than the M26 Pershing in the theater. However, the rapid development and fielding of the M46 showed technical problems in the field, with breakdowns associated to problems with components like the engine oil cooler fan.[8] Nevertheless, the M46s were used effectively before and after the Chinese became involved with the Korean War, with 97 M46s in the Eight Army being involved with the January 1951 counter-offensive against the Chinese.[2] One feature that was tested with the M46 Pattons was the attachment of a searchlight onto the tank to have better battlefield illumination for night battles. The original idea called for taking a M4A3 Sherman tank to be designed with a special turret accommodating a searchlight and a 75 mm gun, designated the T52 searchlight tank. An alternative solution was devised by attaching searchlights atop tank cannons, which proved to be cheap enough to not warrant a new tank design and convenient enough for any tank to be equipped with a searchlight.[6]

The Korean War would end in a ceasefire brought about by an armistice. Due to the armistice dictating the restrictions of weapon imports into the region, the M46s continued to serve there in American hands as America developed their newer tank models. By 14 February 1957, OTCM 36468 would declare the M46 and M46A1 as obsolete, with the Americans only using the M46 in Korea until they are retired from lack of spare parts.[6]

After the end of the Korean War, the M46 became part of America's weapon exports to Europe. However, as America's tank productions churn out the M47 Patton II tank, the value of the M26 and M46 for combat-ready units was not high. The M26 and M46 tanks would be exported as training vehicles to prepare crew for the receiving of M47s. Though France, Belgium, and Italy received M26s for this role, Belgium would also receive eight M46A1 that were used as training vehicles at Leopoldsburg tank training center.[2] Many more M46s would find themselves as range targets.[7]


Archive of the in-game description

The M26, which appeared close to the end of World War II, was an excellent tank. However, power-to-weight ratio, manoeuvrability, and range were lacking. A special new 12-cylinder, air-cooled engine developed by Continental Motors to take care of the manoeuvrability issue reached 29,361 cm³, and at 2,800 rpm its 704 hp outstripped the M26's 500 hp. The 6.5-fold compression, which was large for the time, required 80 octane fuel, and the air-cooling system often overheated the engine. Giving the tank a new power plant required a replacement roof for the compartment housing the engine and transmission, resulting in the use of a single grating.

The new automatic CD-850 gearbox and steering mechanism were operated using a single lever that served both as a gearshift and steering wheel. The M46's running gear gained another small roller to keep constant tension on the tracks and prevent them from slipping between the leading wheels and rear road wheels. In addition, the front suspension points were given second shock absorbers. The tank was built for low temperatures and had water-crossing special equipment. As a result, it was heavier, though it did not suffer from reduced speed thanks to its upgraded power plant.

In 1948 the modernized tank was accepted as the M46 Patton and mass produced from 1949 through 1951. A total of 1,168 units spread across two modifications were built.

The M46 medium tank was used by US forces during the Korean War from 1950 to 1953 and also served as part of the American forces in Europe.
