The '''{{Specs|name}}''' ({{Annotation|九五式軽戦車「ハ号」|Kyūgo-Shiki Kei-Sensha [Ha-Gō]}}) was developed in response to the limitations of the [[I-Go Ko|Type 89 I-Go]], which became evident as it could not keep pace with motorized infantry moving at 40 km/h. Consequently, it failed to fulfil its role as a "light tank," as it had to cover long distances separately by train, akin to other heavy equipment. The primary goal was to ensure that the new tank could match the speed of motorized infantry, facilitating their combined mobility. By 1935, when the design was finalized, the Ha-Go would assume the role of the Army's primary tank until the development of the Chi-Ha. Due to its lightweight and cost-effective design, the Ha-Go became Japan's most numerous tank built during the war.

The '''Type 89b I-Go Ko''' is a reserve Rank I Japanese light tank with a battle rating of 1.0. It was introduced in [[Update_1.65_"Way_of_the_Samurai"|Update 1.65 "Way of the Samurai"]] along with the rest of the initial Japanese Ground Forces Tree.
+
Introduced in [[Update 1.65 "Way of the Samurai"]] along with the initial Japanese Ground Forces Tree, the Ha-Go is a small yet nimble tank, serving as a primary flanking support vehicle to assist larger tanks in advancing. However, due to its limited armour, typical of early Japanese tanks, it can be easily penetrated by cannons and autocannons. To make the most of the Ha-Go's capabilities, it is recommended to use its gun depression by hiding the hull behind terrain and obstacles while exposing only the turret to the enemy.
 +
 
 +
The {{PAGENAME}} was removed from its reserve status and hidden from the main tech tree during [[Update 1.85 "Supersonic"]] after the ammo update, but becomes unlockable after reaching rank II Japanese ground vehicles.

The Type 89b I-Go Ko, despite its rather sluggish looks, is a mobile tank that could use its speed to get to an enemy's flanks and cause some serious damage. The 57 mm cannon is unfortunately rather pitiful even in Rank I, with a penetration value of between 20 to 30 mm at standard combat ranges. Thus, it is best to catch an enemy by its sides in order to get through their weaker side armour. The 57 mm low-velocity shell does have an advantage of a rather prominent parabolic trajectory so it is possible to lob shells over hills to hit unsuspecting enemies behind it.
 
  
Pretty much everything is a threat to this vehicle. '''Fast vehicles''' (BT-7, BT-5, M2A1, Tetrarch, T-60) in particular are an uneasy encounter: at close range, the I-Go's poor turret turning speed cannot follow the movement and at long range, the slow shells are a pain to aim precisely at a moving target. '''Autocanons''' (72-K GAZ AAA, Pz. II, Flakpanzer, Gepard, M13, T17E2, etc.) are the I-Go Ko's worst nightmare since they can make mincemeat of the armour in seconds without too much efforts. Plus, they are often quite fast.
+
As a light tank in a Rank I battle, the best overall tactic is to get the first jump on an enemy since the Ha-Go's gun is able to penetrate most tank's armour, yet everyone else's can also penetrate the Ha-Go. In an offensive, try to attack the enemy from a direction not covered to catch them by surprise, then exploit it by using the Ha-Go's mobility to keep moving around the enemy once it gets close so the enemy could not get an accurate bead on it. In a defensive, hold back and try to cover a single area of contact so the Ha-Go could dispel its fire on any enemy approaching.

'''Pros:'''
 
'''Pros:'''
  
* Decent forward speed.
+
* Excellent gun depression and elevation
* Parabolic trajectory allows 57 mm round to hit over hills.
+
* APHE shell with good post-penetration damage
* APHE has a huge amount of explosive mass, especially for the caliber.
+
* Good top speed (50 km/h on flat surface)
* Great gun depression.
+
* Small silhouette like the [[Panzer II]], easy to hide behind cover
  
 
'''Cons:'''
 
'''Cons:'''
  
* Weak overall armour of 17 mm, vulnerable to any armament.
+
* Outdated 37 mm cannon with mediocre penetration, making a lot of tanks impervious to your shells
* 57 mm armament has very low muzzle velocity and penetration - can struggle to hurt many of the tanks it will face, even from the sides.
+
* Weak armour (12.7 mm machine guns are able to knock out the Ha-Go easily)
* Slow traverse speed even when upgraded.
+
* Reverse speed is 5 km/h on any terrain
* Rather tall as a Rank I tank (not as bad as [[LVT(A)(1)]] though).
+
* Three-man crew which means that the Ha-Go can be destroyed by a single shot, maybe two if lucky
* Machine gun only fires forwards in a limited arc.
+
* Turns are sluggish at any speed.

===Development===
 
===Development===
Japan's early pioneering into the concept of armoured warfare began as early as October 1918 during the first World War. They were able to acquire a few tank samples from the European governments, ranging from a British Mark IV tank, Medium A Whippet tanks, and Renault FT tanks. These tanks would make up Japan's first tank units in 1925. Their experiences with these tanks led to their eventual development of their own domestic tank design.The requirement for this new tank was given to the 4th Military Laboratory under Imperial Japanese Army's jurisdiction and was mainly in charge of land vehicle development. In the summer of 1926,the first prototype was completed with the design of three turrets, one main in the middle and two smaller ones in the front and rear. The design was deemed too heavy at 18 tons and so development restarted, the initial design carrying on in the failed Type 91 and 95 tanks. During this time, a trial with a British Vickers Model C tank had the tank's gasoline engine catch fire. This prompted the Japanese to fit their tanks with a diesel engine instead. The development led to a new design in 1929, titled '''Type 89 I-Go'''. Though it is considered to be a light tank, the designation changed to a medium tank due to its weight of 10 tons.<ref name="ZalogaJapaneseTank">Zaloga Steven. ''Japanese Tanks 1939-1945'' Great Britain: Osprey Publishing Ltd., 2007</ref>
+
The deployment of the first Japanese domestic tank design, the [[I-Go Ko|Type 89 I-Go]], gave the Japanese good insight on the improvement of their armoured force. One of the pressing issues of the Type 89 was that the tank was too slow to keep up with motorized infantry, restricting the operational range or advance of a combined-arm unit to only 40 kilometers. Another tank design being fielded by the Type 89, the Type 92 cavalry tank, had the speed that fixes this problem, but its armour was too thin and only had a heavy machine gun armament. Thus, development started in July 1933 on a tank able to fix these problem, with the specifications that the tank should weigh only 7.7 tons and armed with a 37 mm gun. With the same engine as the Type 89, but half of its weight, the new tank would have a faster road speed.<ref name="ZalogaJapaneseTank">Zaloga Steven. ''Japanese Tanks 1939-1945'' Great Britain: Osprey Publishing Ltd., 2007</ref>
  
The Type 89's construction was assigned to Sagami Arsenal, but it was subcontracted to private firms due to Sagami's lack in industry. One of the firms was Mitsubishi Heavy Industries, whom developed a tank plant specifically for the Type 89. The Type 89 production officially started in 1931, with mass-production in 1933 and continued until 1939 with 404 tanks built.<ref name="ZalogaJapaneseTank">Zaloga Steven. ''Japanese Tanks 1939-1945'' Great Britain: Osprey Publishing Ltd., 2007</ref>
+
The production of the designs was given to Mitsubishi, with a prototype produced and ready for trials in June 1934. The design was sent to Manchuria and performed cold weather trials in the Independent Mixed Brigade. These trials were positive and the second prototype design was built in June 1935 with improvements based on the trials. With a well-received performance of the design, it was accepted for service in the Imperial Japanese Army as the '''Type 95 Ha-Go''' light tank (Accepted in 1935, Imperial year 2595. 'Ha-Go' name given by Mitsubishi).<ref name="ZalogaJapaneseTank">Zaloga Steven. ''Japanese Tanks 1939-1945'' Great Britain: Osprey Publishing Ltd., 2007</ref> Production lasted from 1936 to 1943, with up to 2,300 tanks produced in the time period, making it the most produced Japanese tank design in World War II.
  
 
===Design===
 
===Design===
The Type 89 I-Go was Japan's first domestic tank design, yet it showed a lot of features that were revolutionary and would become a trademark of the Japanese tank designs. The Type 89 I-Go had a four-man crew in the tank with two in the turret. The turret held a 57 mm low-velocity gun meant for fighting fortifications due to the tank's role as an infantry support. A peculiar feature on the Type 89 was the rear machine gun on the back of the turret. This machine gun was meant to enable the Type 89 to engage forward targets with a machine gun or its 57 mm gun and would be a design trend in future tank development.<ref name="ZalogaJapaneseTank">Zaloga Steven. ''Japanese Tanks 1939-1945'' Great Britain: Osprey Publishing Ltd., 2007</ref>

The Type 95 Ha-Go was a light tank weighing roughly 7.7 tons. It had a three-man crew with a turret that only held one person inside. The turret was armed with a 37 mm gun, as well as a machine gun mount on the rear of the turret just like the Type 89. The machine gun armament on the back allowed the commander to simply traverse the turret to use a certain armament for the situation desired. Despite that, the one-man turret meant the commander was overworked.
  
The Type 89 design changed gradually over time due to troop experience and advances in technology. For example, a small change that occurred for the Type 89 was the change of the commander's cupola from a "top hat" or "lid" design to a split hatch design. A noticeable change was in the engine when the first models produced off the lines were powered by a 118hp gasoline engine, these tanks were labeled as ''Type 89A I-Go Ko''. It wasn't until 1934 when a change to 120hp Mitsubishi diesel engine was made that the Type 89 was redesignated the ''Type 89B I-Go Otsu''. This diesel engine made the Type 89 the first mass-produced tank that uses diesel as its fuel.<ref name="ZalogaJapaneseTank">Zaloga Steven.

The tank used the same engine on the Type 89B, the 120 hp Mitsubishi diesel engine. The suspension on the tank was quite simple, two bogies with wheels suspended on a bell crank with a front sprocket and two return rollers on each side. The two bogies were attached to a brace, connecting the two to fix problems with the pitching that inhibited the tank's driving ability, but the suspension still gave the crew a rough ride when driving on uneven ground. A unique feature on the Type 95 design was that there was an asbestos padding area separating the interior area from the hull armour to protect the crew from burning on hot metal armour and from injury on hitting the hull from the tank's rough driving experience.
  
The Type 89 does carry its few flaws, however. The tank was quite slow at about 25 km/h (16 mph), a hinderance to mobile operations using motorized infantry that must wait for the tanks to reach the combat zone. The armour was quite thin at 17 mm and the 57 mm's anti-tank power was quite abyssal. However, against the Chinese troops from 1932 onwards, the armour and firepower flaws were small worries due to the lack of available tanks and anti-tank defenses in the Chinese side.

===Combat usage===
 +
The Type 95 was first deployed in the Second Sino-Japanese War. The Type 95s in the theater were generally well-received due to the inferiority of China's anti-tank defenses and their tank forces usually consist of machine gun-armed tanks like the Panzer I and CV33. The Type 95 Ha-Go's first major combat was during the border conflicts between Japan and the Soviet Union during the battles at Khalkhin Gol. The Type 95 made up a good portion of the 4th Tank Regiment in the 1st Tank Corps, alongside [[I-Go Ko|Type 89]]s and Type 94 tankettes. These tanks generally fought against the Soviet [[BT-5]] and [[BT-7]] tanks, which were in the same class as the Ha-Gos, though the Japanese took special note on the 45 mm cannon on the Soviet tanks, which they deemed superior to the Ha-Go 37 mm cannon. The two side exchanged multiple battles and territories, eventually resulting in a ceasefire between the two nations in August 1939.
  
===Combat Usage===
+
The next major usage of the Type 95 Ha-Go would be in opening stages of World War II when Japan invades the Allied territory after their surprise attack on Pearl Harbor on 7 December 1941. Their first usage was in the Malaya campaign, then Singapore, then the Burma campaign. Despite the British technological superiority over the Japanese with their tank designs in Europe, their self-created concept that tanks were next-to-useless in the Pacific jungles caused them to have a severe shortage of armour in the Pacific in the early stages of the war. The Japanese however, with no experience in jungle warfare, managed to invade with Type 95 alongside [[Chi-Ha|Type 97 mediums]] as their spearhead. The Type 95 would also be involved with America's first tank-to-tank battle during the Battle of the Philippines. Type 95s from the 4th Tank Regiment came across U.S. [[M3 Stuart|M3 Stuarts]] from the 192nd Tank Battalion. Despite the Stuarts being five years newer than the Type 95, the two tanks were deemed very similar performance-wise. In this engagement, the Type 95 managed to spot the U.S. tanks first and open fired, destroying one of the Stuarts in the platoon and the west withdrew under fire.
The Type 89 was first used in 1932 in the 1st Special Tank Company after the Manchurian Incident. The company, armed with Type 89 along with Renault FT and NC tanks, took part in the conflict between China and Japan in the Shanghai Incident. The experience showed that the Type 89 performed well in comparison to the Renaults and soon the entire company was fitted with Type 89s, retiring the Renaults.<ref name="ZalogaJapaneseTank">Zaloga Steven. ''Japanese Tanks 1939-1945'' Great Britain: Osprey Publishing Ltd., 2007</ref>
 
  
The mass production of the Type 89 from 1933 onwards allowed the formation of large tank groups in Japan, leading to the 1st and 3rd Tank Regiment in Kurume, Fukuoka with the 2nd Tank Regiment at Chiba Tank School. The 1st Tank Regiment would be deployed with the Kwantung Army in China, where it would carry the Type 89 tank in the conflcit against China from 1937 onwards.<ref name="ZalogaJapaneseTank">Zaloga Steven. ''Japanese Tanks 1939-1945'' Great Britain: Osprey Publishing Ltd., 2007</ref>
+
The Japanese continued using their Ha-Go in the Pacific Theater all the way until the end of the war. Even when outmatched by the newer American tanks like the [[M4|M4 Shermans]], the lack of any better equipment forced the Japanese Army to play with what they've got left. This led to costly defeats in the Japanese tank units on Tarawa, Saipan, Guam, Peleliu, and Okinawa as the tank units were used in reckless charges or static pillboxes as they were destroyed via tank, cannon, or bazooka fire.
  
By 1939, the Type 89 was starting to be succeeded by newer Japanese tanks, but they still served on the frontlines such as the border conflcits between Japan and the Soviet Union. In the Battle of Khalkhin Gol, the IJA's 1st Tank Corps attacked the Soviet 11th Tank and 7th Armoured brigades in July with a mixture of Type 89s, [[Chi-Ha|Type 97 mediums]], [[Ha-Go|Type 95 lights]], and tankettes in the 3rd and 4th Tank Regiments. Though the attack stirred up Soviet lines, there was no breakthrough in Soviet lines. The Soviets, armed with [[T-26|T-26]] and [[BT-5|BT]] [[BT-7|light tanks]], would soon push the Japanese back to Manchuria and have a cease-fire signed on 24 August.
+
After the war, the remnants of the Japanese Army left behind a huge number of Type 95 Ha-Go in their depot at the occupied territory. This led to a massive amount of tanks being captured and used by the opposing sides of the Chinese Civil War. Another curious user of the captured Japanese tanks were the French, which captured them from Japanese-occupied area in French Indochina. The French used the Japanese tanks alongside French tanks to hastily make units called 'Commando Blindé du Cambodge' to fight in the First Indochina War.
  
Though the Type 89 was mostly withdrawn from service and replaced with the [[Ha-Go|Ha-Go]] and [[Chi-Ha|Chi-Ha]], the I-Go still served as far into the battles for Philippines, Malaya, and Burma. Some tanks saw further use as static pillboxes in the Japanese islands of the Pacific, but these tanks were vulnerable to newer anti-tank and tank technology of the Americans with their bazookas and [[M4|M4 Shermans]] once they started their island-hopping strategy against Imperial Japan.

Ha-Go

Description

The Type 95 Ha-Go (九五式軽戦車「ハ号」) was developed in response to the limitations of the Type 89 I-Go, which became evident as it could not keep pace with motorized infantry moving at 40 km/h. Consequently, it failed to fulfil its role as a "light tank," as it had to cover long distances separately by train, akin to other heavy equipment. The primary goal was to ensure that the new tank could match the speed of motorized infantry, facilitating their combined mobility. By 1935, when the design was finalized, the Ha-Go would assume the role of the Army's primary tank until the development of the Chi-Ha. Due to its lightweight and cost-effective design, the Ha-Go became Japan's most numerous tank built during the war.

Introduced in Update 1.65 "Way of the Samurai" along with the initial Japanese Ground Forces Tree, the Ha-Go is a small yet nimble tank, serving as a primary flanking support vehicle to assist larger tanks in advancing. However, due to its limited armour, typical of early Japanese tanks, it can be easily penetrated by cannons and autocannons. To make the most of the Ha-Go's capabilities, it is recommended to use its gun depression by hiding the hull behind terrain and obstacles while exposing only the turret to the enemy.

The Ha-Go was removed from its reserve status and hidden from the main tech tree during Update 1.85 "Supersonic" after the ammo update, but becomes unlockable after reaching rank II Japanese ground vehicles.

Usage in battles

As a light tank in a Rank I battle, the best overall tactic is to get the first jump on an enemy since the Ha-Go's gun is able to penetrate most tank's armour, yet everyone else's can also penetrate the Ha-Go. In an offensive, try to attack the enemy from a direction not covered to catch them by surprise, then exploit it by using the Ha-Go's mobility to keep moving around the enemy once it gets close so the enemy could not get an accurate bead on it. In a defensive, hold back and try to cover a single area of contact so the Ha-Go could dispel its fire on any enemy approaching.

Pros and cons

Pros:

  • Excellent gun depression and elevation
  • APHE shell with good post-penetration damage
  • Good top speed (50 km/h on flat surface)
  • Small silhouette like the Panzer II, easy to hide behind cover

Cons:

  • Outdated 37 mm cannon with mediocre penetration, making a lot of tanks impervious to your shells
  • Weak armour (12.7 mm machine guns are able to knock out the Ha-Go easily)
  • Reverse speed is 5 km/h on any terrain
  • Three-man crew which means that the Ha-Go can be destroyed by a single shot, maybe two if lucky
  • Turns are sluggish at any speed.

History

Development

The deployment of the first Japanese domestic tank design, the Type 89 I-Go, gave the Japanese good insight on the improvement of their armoured force. One of the pressing issues of the Type 89 was that the tank was too slow to keep up with motorized infantry, restricting the operational range or advance of a combined-arm unit to only 40 kilometers. Another tank design being fielded by the Type 89, the Type 92 cavalry tank, had the speed that fixes this problem, but its armour was too thin and only had a heavy machine gun armament. Thus, development started in July 1933 on a tank able to fix these problem, with the specifications that the tank should weigh only 7.7 tons and armed with a 37 mm gun. With the same engine as the Type 89, but half of its weight, the new tank would have a faster road speed.[1]

The production of the designs was given to Mitsubishi, with a prototype produced and ready for trials in June 1934. The design was sent to Manchuria and performed cold weather trials in the Independent Mixed Brigade. These trials were positive and the second prototype design was built in June 1935 with improvements based on the trials. With a well-received performance of the design, it was accepted for service in the Imperial Japanese Army as the Type 95 Ha-Go light tank (Accepted in 1935, Imperial year 2595. 'Ha-Go' name given by Mitsubishi).[1] Production lasted from 1936 to 1943, with up to 2,300 tanks produced in the time period, making it the most produced Japanese tank design in World War II.

Design

The Type 95 Ha-Go was a light tank weighing roughly 7.7 tons. It had a three-man crew with a turret that only held one person inside. The turret was armed with a 37 mm gun, as well as a machine gun mount on the rear of the turret just like the Type 89. The machine gun armament on the back allowed the commander to simply traverse the turret to use a certain armament for the situation desired. Despite that, the one-man turret meant the commander was overworked.

The tank used the same engine on the Type 89B, the 120 hp Mitsubishi diesel engine. The suspension on the tank was quite simple, two bogies with wheels suspended on a bell crank with a front sprocket and two return rollers on each side. The two bogies were attached to a brace, connecting the two to fix problems with the pitching that inhibited the tank's driving ability, but the suspension still gave the crew a rough ride when driving on uneven ground. A unique feature on the Type 95 design was that there was an asbestos padding area separating the interior area from the hull armour to protect the crew from burning on hot metal armour and from injury on hitting the hull from the tank's rough driving experience.

Combat usage

The Type 95 was first deployed in the Second Sino-Japanese War. The Type 95s in the theater were generally well-received due to the inferiority of China's anti-tank defenses and their tank forces usually consist of machine gun-armed tanks like the Panzer I and CV33. The Type 95 Ha-Go's first major combat was during the border conflicts between Japan and the Soviet Union during the battles at Khalkhin Gol. The Type 95 made up a good portion of the 4th Tank Regiment in the 1st Tank Corps, alongside Type 89s and Type 94 tankettes. These tanks generally fought against the Soviet BT-5 and BT-7 tanks, which were in the same class as the Ha-Gos, though the Japanese took special note on the 45 mm cannon on the Soviet tanks, which they deemed superior to the Ha-Go 37 mm cannon. The two side exchanged multiple battles and territories, eventually resulting in a ceasefire between the two nations in August 1939.

The next major usage of the Type 95 Ha-Go would be in opening stages of World War II when Japan invades the Allied territory after their surprise attack on Pearl Harbor on 7 December 1941. Their first usage was in the Malaya campaign, then Singapore, then the Burma campaign. Despite the British technological superiority over the Japanese with their tank designs in Europe, their self-created concept that tanks were next-to-useless in the Pacific jungles caused them to have a severe shortage of armour in the Pacific in the early stages of the war. The Japanese however, with no experience in jungle warfare, managed to invade with Type 95 alongside Type 97 mediums as their spearhead. The Type 95 would also be involved with America's first tank-to-tank battle during the Battle of the Philippines. Type 95s from the 4th Tank Regiment came across U.S. M3 Stuarts from the 192nd Tank Battalion. Despite the Stuarts being five years newer than the Type 95, the two tanks were deemed very similar performance-wise. In this engagement, the Type 95 managed to spot the U.S. tanks first and open fired, destroying one of the Stuarts in the platoon and the west withdrew under fire.

Another curious user of the captured Japanese tanks were the French, which captured them from Japanese-occupied area in French Indochina. The French used the Japanese tanks alongside French tanks to hastily make units called 'Commando Blindé du Cambodge' to fight in the First Indochina War.
