The '''{{Specs|name}}''' is a Rank {{Specs|rank}} American medium tank {{Battle-rating}}. It was introduced in [[Update 1.45 "Steel Generals"]] along with the rest of American Ground Forces. It uses a similar hull as its predecessor, the [[M46|M46 Patton]], but features a new turret and a better gun.
+
The '''{{specs|name}}''' is a Rank {{specs|rank}} Japanese medium tank {{Battle-rating|1}}. It was introduced along with the entire Japanese Ground Forces tree in [[Update_1.65_"Way_of_the_Samurai"|Update 1.65 "Way of the Samurai"]]. The prototype of the [[Type 74]], the STB-1 presents many features that would be in the final design.
 +
 
 +
The STB-1 is the first researchable tank in Japan's Ground Forces Rank V. Despite having considerable more armour than its comparable counterparts the Leopard 1 and Leopard A1A1, as well as comparable mobility, it is not recommended as a front-line tank like the 'Allied' counterparts. Instead, a cautious hit-and-run tactic like the Leopards should always be employed. Using the tank's [[hydropneumatic suspension]] correctly can help with the tank's depression, and in some cases, aid in survivability. Do note that the L7 on this tank reloads significantly longer than other L7-equipped tanks.
 +
 
 +
The STB-1 is unique among being one of the only Japanese tanks that can take a hit, like the Type 4 Chi-To Late and Type 5 Ho-Ri Production. It has thick frontal hull armour that can bounce shots effectively, but should not be relied on. The tank is quite fast and is further aided by the Hydropneumatic suspension, which allows this tank to manoeuvre the battlefield much like a Leopard, however the abundance of larger, more open maps at higher ranks means that getting from point A to B - and not getting shot - is not a simple as it sounds.

−
* Suspension wheels are 20 mm thick, tracks are 30 mm thick.
 
  
−
In Rank V, the M47 Patton does not have suitable armour against the numerous 88 mm, 100 mm, and 122 mm calibers running around the field. However, it makes up for that with a potent 90 mm cannon with new ammunition able to fight back. Due to the armour thickness of the Rank V tanks, it is recommended to use the M47 Patton's speed to flank the enemy, then engage them on their sides to detonate their ammo racks or knock out the crew.
+
* Suspension wheels and tracks are 20 mm thick.
 +
* Driver's vision port on the front glacis are only 50 mm thick.
 +
* Hull roof is rated to be 54 mm effective against HE.

The STB-1, while often compared as a 'better' Leopard 1, should still be treated carefully as a tank. Aggressive play is not unsafe and can be very rewarding at times. Keep in mind the STB-1 has a chance of bouncing, but most shots in the turret result in loss of horizontal turret drive, cannon breech, or essential crew.
 +
 
 +
The STB's biggest threats are agile vehicles with fast reloads. Due to a reload that is longer than many other tanks you want your first shot to disable their gun.

===Development===
 
−
The '''M47 Patton''' came about only a few years after its predecessor, the [[M46|M46 Patton]]. The basis of this design was the [[M26|M26 Pershing]], which was deemed insufficiently mobile for its role as a medium tank. The M46 was mainly the M26 Pershing with a new engine, transmission, and a redesigned 90 mm gun. While a good solution for the lacking M26 Pershing design, it was only considered a stopgap solution while the experimental ''T42 medium tank'' was being developed. However, the Korean War put a stop in that development due to an urgent need of tanks, so the T42 project, which would produce a completely new tank design, was put on-hold.

An interim decision was made to mount the turret from the T42 onto the hull of the M46 Patton, this modified tank was designated the '''M47 Patton''' and entered production in 1951. A common nickname for the tank was the ''Patton II'', due to the same name as the M46 Patton, this was changed to ''Patton 47'' a few weeks later. The M47 Patton featured most of the armament seen from the M26 Pershing and M46 Patton, with a 90 mm gun and a coaxial and hull-mounted .30 cal machine gun, and a .50 cal machine gun on top of the turret. The M47 Patton has the distinction of being the last American tank with the hull-mounted machine gun on the bow. The new turret required the hull to be redesigned with a larger turret ring and had a "needle-nose" design with the turret mantlet heavily sloped towards the cannon, the design's heavy sloping nature also helped improve protection. The turret also had a large protrusion at the back to act as storage. A M12 stereoscopic range finder was also mounted on a turret, which was difficult to use, but would appear in every American tank design from here on until the M1 Abrams design.

Though technically a medium tank by the army standards, a new standardization in US Army tank designation in November 9, 1950 had the entire system changed from the weight of the tank to the caliber of the vehicle's gun. Therefore in 1950s, the "Medium Tank M47 Patton" name was changed to '''90 mm Gun Tank M47 Patton'''. This designation would go on for future American tank designs. The M47 Patton began production in June 1951 before its standardization at the Detroit Tank Arsenal. Delays in the production schedule caused a long period of testing to occur until it was standardized in May 1952. Production ran until November 1953 with a total production number of more than 9,000 M47 Pattons between Detroit and Alco.

The M47 Patton came out only a year before the improved M48 Patton. Because of this, the M47 was declared a "limited standard" in American service, and those still in American hands were replaced by the M48 Patton tanks. It was declared obsolete by 1957 and were only retained by infantry divisions until replaced by anti-tank missiles in the 1960s. The M47 Pattons were given out in large numbers to a number of countries in NATO and SEATO, such as Pakistan, Jordan, Turkey, Iran, Croatia, France, West Germany, and Spain. The M47 Pattons would see service in combat in both Indo-Pakistani Wars, the Six Day War, the Iran-Iraq war, the Invasion of Cyprus, and the Croatian War of Independence. Today, they are still being used in Spain as armour recovery vehicles in artillery and infantry units.

The M47 Pattons were promising new designs developed from the M46 Pattons to improve its combat capabilities with a newer turret. However, it did not serve much in America due to the M48 Patton development, which was a completely new deign and had nearly no identical parts with its predecessor. It served very well in other countries as their primary armour forces, but those left in the states were used as targets in firing ranges, mainly for training or as tests for future anti-tank developments. In the 1970s, one was tested against the [[M60|M60 Main Battle Tank]], the successor to the M48 Patton, and its 105 mm L7 gun. The HEAT round fired from the gun penetrated the frontal armour of the M47 Patton with relative ease, armour which was considered superb at its time of introduction. The test went on with many M47 tanks and would prove that conventional steel armour in tank warfare was becoming obsolete in the face of new tank ammo.

Description

GarageImage STB-2.jpg


The STB-2 is a Rank V Japanese medium tank with a battle rating of 8.3 (AB/RB/SB). It was introduced along with the entire Japanese Ground Forces tree in Update 1.65 "Way of the Samurai". The prototype of the Type 74, the STB-1 presents many features that would be in the final design.

The STB-1 is the first researchable tank in Japan's Ground Forces Rank V. Despite having considerable more armour than its comparable counterparts the Leopard 1 and Leopard A1A1, as well as comparable mobility, it is not recommended as a front-line tank like the 'Allied' counterparts. Instead, a cautious hit-and-run tactic like the Leopards should always be employed. Using the tank's hydropneumatic suspension correctly can help with the tank's depression, and in some cases, aid in survivability. Do note that the L7 on this tank reloads significantly longer than other L7-equipped tanks.

The STB-1 is unique among being one of the only Japanese tanks that can take a hit, like the Type 4 Chi-To Late and Type 5 Ho-Ri Production. It has thick frontal hull armour that can bounce shots effectively, but should not be relied on. The tank is quite fast and is further aided by the Hydropneumatic suspension, which allows this tank to manoeuvre the battlefield much like a Leopard, however the abundance of larger, more open maps at higher ranks means that getting from point A to B - and not getting shot - is not a simple as it sounds.

Usage in the battles

The STB-1, while often compared as a 'better' Leopard 1, should still be treated carefully as a tank. Aggressive play is not unsafe and can be very rewarding at times. Keep in mind the STB-1 has a chance of bouncing, but most shots in the turret result in loss of horizontal turret drive, cannon breech, or essential crew.

The STB's biggest threats are agile vehicles with fast reloads. Due to a reload that is longer than many other tanks you want your first shot to disable their gun.

Pros and cons

Pros:

  • Highly mobile, comparable to the German Leopard I.
  • More armour than the German Leopard (around 100m hull and turret).
  • 105 mm L7 cannon found on other NATO tanks.
  • May bounce APHE shells.
  • Low profile.
  • Utilization of hydropneumatic suspension allows for various offensive and defensive options.
  • 12.7 mm Browning Machine Gun.

Cons:

  • Other areas are lightly armoured, vulnerable to high penetrating SPAA.
  • Reload and top speed slower than Leopard.
  • Small gun elevation angle.
  • Engine vulnerable to some aircraft with powerful guns.
