Type 95 Ha-Go light tank


The Type 95 Ha-Gō was a light tank used by the Empire of Japan during the Second Sino-Japanese War, at Nomonhan against the Soviet Union, and in the Second World War. It proved sufficient against infantry but, like the American M3 Stuart light tank, was not designed to combat other tanks. Approximately 2,300 were produced, making it the most numerous Japanese armoured fighting vehicle of the Second World War.

History and development

From early 1930s, the Japanese army began experimenting with a mechanized warfare unit combining infantry with tanks. However, the Type 89 Medium tank could not keep pace with the motorized infantry, which could move at by truck. For transport, tanks could be loaded on train platforms like in any other army of the times. To solve this problem, Tomio Hara of the Army Technical Bureau proposed a new light tank capable of 40 km/h speed and started development in 1933.
The prototype of the tank was begun in 1933 and completed in June 1934 at the Army's Sagami Arsenal. Initial tests were positive, but it was too heavy at 7.5 tons and was reworked to bring the weight down to 6.5 tons. Due to doubts by the infantry as to its capability for infantry support it was tested in Manchuria in the winter of 1934/1935. The reports were favourable and a second prototype built, which was started in June and completed in November 1935.
In 1935, at a meeting in the Army Technical Bureau, the Type 95 was proposed as the main tank for mechanized infantry units. The infantry had concerns that the armor was insufficient; however, the cavalry indicated that the improved speed and armament compensated for thin armor. In the end, the infantry agreed, as the Type 95 was still superior to the available alternatives of the Type 92 cavalry tank and Type 94 tankette.
The name was based on the year since the beginning of the Empire that the tank was produced; Type 2595. Sometimes a surname was used to supplement or replace the naming ideograms used for Japanese armored fighting vehicles. The Type 95 had the surname "Ha-Go" that was given by the designer of the tank, Mitsubishi Heavy Industries. Mitsubishi Heavy Industries started production of the tank in 1936. Mass production began in 1938 with the tank and parts made by several different companies; besides Mitsubishi, that included, Niigata Tekkoshō, Dowa Jido Sho, Sagami Arsenal Kokura Rikugu Jiohei Sho and Ihesil.

Design

The Type 95 was a 7.4-ton vehicle with a complement of 3 crewmen: a commander, a hull machine gunner, and a driver. Only the commander was seated in the turret, hence he was responsible for observation, loading, aiming, firing the main gun, as well as decision-making and commanding the crew. The hand-operated turret was small and extremely cramped.
The primary armament of the most produced version was a Type 94 37 mm tank gun with a barrel length of 46.1 calibers. It elevated between −15 to +20 degrees. The tank carried two types of 37 mm ammunition, the high-explosive and armor-piercing. For the latter, muzzle velocity was and armor penetration was at a distance of.
Secondary armament was originally two 6.5 mm Type 91 machine guns, but these were replaced with two 7.7 mm Type 97 light machine guns, one mounted in the hull front and the other in the back of the turret, facing to the rear right.
The most characteristic feature of the Type 95 tank was its simple suspension system. Army officer Tomio Hara designed the bell crank scissors system. This suspension system became standard on the majority of the subsequently designed Japanese tanks. For the Type 95, two paired bogie wheels per side were suspended on a single bell crank and connected to a coil spring mounted horizontally outside the hull. The tracks were driven through the front sprockets. There were two return wheels. The suspension had troubles early on, with a tendency to pitch on rough ground, and so it was modified with a brace to connect the pairs of bogies. Despite this, the tank continued to give its users a rough ride across any uneven ground. It was provided with an interior layer of asbestos padding separated from the hull with an air gap, to isolate the crew from the sun-heated armor plates, and to protect the crew from injury when the tank moved across rough terrain.
The Type 95 was fitted with a 120 hp Mitsubishi A6120VDe air-cooled 6-cylinder diesel engine. It was located in the rear compartment on the right side. The power unit gave it good mobility. Some tanks were fitted with two reflectors in the front of the vehicle for night operations.

Variants

The tank was considered one of the best of its type in 1935, being armed with a 37 mm cannon, and powered by a diesel engine, a fuel considered by some to be superior due to its low volatility. As with most armies in the 1930s the tank, and the light tank in particular, were used primarily to support infantry or serve as cavalry reconnaissance and to a lesser extent, as raiding vehicles. Its speed was about 18 mph cross country, which was comparable to the M3 Stuart's 20 mph nearly 6 years later in 1941. In armor, road speed, and weaponry, the Type 95 was far inferior to the American M3 Stuart light tanks, but the environment of the Philippines largely minimized these disadvantages and allowed the Type 95 to be competitive, as its off-road speed and turret rotation were comparable.
Type 95 proved sufficient against opposing infantry in campaigns in Manchuria and China, as the Chinese National Revolutionary Army had only three tank battalions consisting of Vickers export tanks, German PzKpfw I light tanks, and Italian CV33 tankettes to oppose them. However, the Type 95, like the US M3 Stuart, was not designed to fight other tanks, but for infantry support. Due to the IJN's priority in receiving new technology and steel for warship construction, tanks for the IJA and the IJN's SNLF detachments were relegated to receiving what was left. By 1942, Japanese armor remained largely the same as it did in the 1930s, and new tank development was "stymied".

Khalkhin Gol (Nomonhan) 1939

Under the mistaken belief that the Red Army was retreating from the area of the Khalkhyn Gol river, the IJA command in Manchuria transferred the 1st Tank Corps, under the command of Lt. Gen. Yasuoka Masaomi to the village of Nomonhan to cut off the retreating Soviets at Khalkhyn Gol. After a two-day journey by rail, the 1st Tank Corps began unloading its 3rd Tank Regiment and 4th Tank Regiment from their trains at Arshaan in Manchuria on 22 June 1939. While the 3rd Tank Regiment was composed primarily of the nearly decade-old Type 89 medium tanks, the 4th Tank Regiment, commanded by 48-year-old Col. Tamada Yoshio, consisted of 35 Type 95 light tanks, eight Type 89s, and three Type 94 tankettes.
From the beginning of Soviet General Zhukov's assumption of command at Nomonhan in June 1939, he had deployed his BT-5 and BT-7 light tanks and incorporated them into all of his combined artillery, infantry, and armor attacks. Although in the same light tank category as the Type 95, also with 3 man crews, and similar dimensions, the BT tanks were nearly twice as heavy, at 13.8 tons but were highly susceptible to close-quarter teams using fire bombs ; that was primarily due to their gasoline engines. As such, Japanese tank crews held a generally low opinion of the Soviet Red Army tanks, but the BT tank's 45 mm gun was a different matter. With a velocity of over, Soviet tanks could penetrate the Japanese tanks at a range of over 1,000 meters ; as one Type 95 tank officer put it, "...no sooner did we see the flash, than there would be a hole in our tank! And the Russians were good shots too!"
On 2 July 1939, at approximately 18:10 hours, Col. Tamada's 4th Tank Regiment of more mobile Type 95 tanks took the lead in front of the medium tanks of the 3rd Tank Regiment, as the 1st Tank Corps launched its first offensive against the Soviet forces at Khalkhin Gol. While the 3rd Tank Regiment passed through Soviet artillery fire, becoming decisively engaged by about 20:00 hours during their movement forward, the 4th Tank Regiment, while avoiding Soviet artillery barrages had advanced in a southeast direction instead of due south, engaging Russian forces southwest of Uzuru pond. Observing a Russian artillery battery between himself and his objective, a "junction", Col. Tamada ordered an attack in the darkness. At about 23:00 hours, the 4th Tank moved towards their objective with about 6 meters between tanks and 30 meters between companies and platoons. Just after midnight, a thunderstorm struck, conveniently exposing the Russian positions while at the same time masking the advancing 4th Tank Regiment. While at close range, the lightning storm suddenly illuminated the advancing Type 95s, and the Soviet defense line immediately opened fire with heavy machine guns, artillery, BT-7 light tanks, and anti-tank guns. However, since the range was so close, the Russian artillery could not depress their barrels low enough to hit the tanks, and their shells flew wildly over the advancing tanks. At about 00:20 hours Col. Tamada ordered the 4th Tank Regiment to "charge", and by 02:00 hours his light tanks had penetrated over 1,000 yards through Russian lines and knocked out 12 artillery guns.
Japanese losses consisted of one Type 95 light tank, one officer and one enlisted man killed and 8 wounded; the 4th Tank had expended approximately 1,100 37 mm and 129 57 mm tank shells, and 16,000 rounds of machine gun ammunition. After the action, the Soviet command acknowledged that 1st Tank Corps armor had reached the Russian guns.

Malaya, Burma and the Philippines, 1941 to 1942

The United States military had been operating in the Philippines since the Philippine–American War and Great Britain had military bases in Singapore since at least the 1840s; they both had many years of so-called "jungle warfare" experience between them, which no doubt influenced their beliefs that "tanks could not operate in those jungles". On the other hand, the Imperial Japanese Army had always been focused upon Russia and China and had never conducted major military campaigns in tropical regions. Facing thick and impenetrable jungles, two experienced and powerful armies, and lacking any jungle combat experience themselves, the IJA's Type 95s, together with Type 97 Chi-Ha medium tanks, led the Japanese assault forces into taking British Malaya and Singapore by 15 February in 1942 and Corregidor in the US-held Philippines by April in that same year. The Type 95 proved to be an extremely successful light tank during the early military campaigns of Japan leading into mid-1942. The "rough terrain" did not prove to be a severe obstacle for the generally-light Japanese armour. In addition, poor planning on the part of the British Army resulted in very few to practically no tanks being deployed by the UK in British Malaya or the British colony of Burma by December 1941.

America's first clash of armor in World War II

's first tank versus tank battle of World War II occurred when Type 95 light tanks of the IJA 4th Tank Regiment engaged a US Army tank platoon, consisting of five brand new M3 Stuart light tanks from "B" company, 192nd Tank Battalion, on 22 December 1941, north of Damortis during the retreat to the Bataan Peninsula in 1941. Both the M3 and Type 95 light tanks were armed with a 37 mm gun, but the M3 was better armored, with 32 mm thick turret sides, vs the Type 95's 12 mm thick armor; however, as the US Army's Ballistics Research Lab found after conducting the first large study of tank vs tank warfare in 1945, the most important factor in a tank duel was which side spotted the enemy first, fired first, and hit first. In this first engagement the IJA reacted first, destroying the lead M3 as it tried to leave the road. The four remaining American tanks all suffered hits as they retreated.
On 6 June 1942, the Japanese 3rd Special Naval Landing Forces landed on Kiska Island during the Japanese invasion of the Aleutian Islands, part of today's state of Alaska. The SNLF landing was reinforced by Type 95 light tanks from the IJAs 11th Tank Regiment, which became the only enemy tanks to ever land on United States soil. After the U.S./Allied landing of Kiska to recapture the island in August 1943, the U.S. captured two Type 95s and transported them to Aberdeen Proving Ground in Maryland for study and evaluation.

Against Australia

Two Type 95 tanks were deployed to support the Japanese landing at Milne Bay, New Guinea, in late August 1942. Initially, the tanks proved successful against the lightly armed Australian infantry, whose 'sticky bombs' failed to stick due to the humidity. Although the tanks had proved reliable in the tropical conditions of Malaya, they could not handle the volume of mud caused by intense, almost daily rainfall at Milne Bay. Both tanks were bogged down and abandoned a few days after the landing.

10-year-old warhorse

The Type 95 first began to show its vulnerability during later battles against British/Commonwealth forces, where the tank's 37 mm gun could not penetrate the armor of the British Matilda infantry tanks which were deployed against them. The thin armor of the Type 95 made it increasingly vulnerable, as Allied forces realized that standard infantry weapons were capable of penetrating the minimal armor around the engine block, and even its thickest armor was vulnerable to heavy machine gun fire. By 1944, it was already known that the 10-year-old Type 95 light tank's firepower was insufficient to take on the newest US tanks, such as the medium M4 Sherman, or the M5 Stuart light tank, although the Type 95 could still give the older M3 Stuart light tank a run for its money at close range.
In August 1942, the US launched its first counter-offensive against Japan, when it landed US Marines on Guadalcanal. The US Marine Corps deployed its 1st Tank Battalion, which was equipped with the only M2A4 light tanks to see combat with US forces during World War II. The M2A4 was the foundation for the M3 Stuart, and both vehicles were nearly identical when viewed side by side; with the primary difference being the rear idler wheel lowered to the ground on the M3. Although the M2A4 was newer by five years, being built in 1940, than the Type 95, it was the closest US tank in armament and armor to the Type 95 light tank; with 25 mm thick turret sides vs the 95's 12 mm turret sides; and both tanks were equipped with 37 mm main guns. Several Type 95s were destroyed or captured by the United States Army during the Battle of Biak in 1944. As the tide of the war turned against Japan, the Type 95s were increasingly expended in banzai charges or were dug-in as pillboxes in static defense positions in the Japanese-occupied islands. During the Battle of Tarawa, seven entrenched Type 95s of the 7th Sasebo SNLF opposed the American landings. Those seven, along with the two on nearby Makin Island, were destroyed. More were destroyed on Parry Island and on Eniwetok. On Saipan, Type 95s attacked the American Marine beachhead at dawn on 16 June 1944, and were destroyed by tank fire. The US Marines had landed the day before with two tank battalions. On the night of 16–17 June, the Japanese made an "all-out counterattack". Leading the attack were 44 tanks of the IJA 9th Tank Regiment. The Type 97s and Type 95s were knocked out by a Marine platoon of M4A2 tanks, several M3 75mm half-tracks, bazookas and 37mm antitank guns. It was the largest Japanese armor attack of the war.
During the Battle of Guam, 29 Type 97 and Type 95 tanks of the IJA 9th Tank Regiment and nine Type 95s of the 24th Tank Company were lost to bazooka fire or M4 tanks. Seven more were destroyed on Tinian on 24 July, and 15 more on Battle of Peleliu on 15 September. Likewise, in the Philippines, at least ten Type 95s were destroyed in various engagements on Leyte, and another 20 on Luzon. At the Battle of Okinawa, 13 Type 95s and 14 Type 97 Shinhoto medium tanks of the understrength IJA 27th Tank Regiment faced 800 American tanks of eight US Army and two USMC tank battalions.

China-Burma-India theater of operations

In 1942 the IJA pushed through Southeast Asia, through Thailand and into Burma, and headed for India. Type 95 light tanks of the IJA 14th Tank Regiment led the way. They engaged the M3 Stuarts of the British 7th Hussars and 2nd Royal Tank Regiment, and as the British retreated towards India, the IJA re-equipped their armoured units, following significant losses of Type 95s in combat, with at least some captured US M3 Stuart light tanks seized from the British. By 1944, the 14th Tank Regiment was effectively starved of its combat supplies due to British deep battle tactics of cutting the IJA's logistical lines, and a final push by the IJA was stopped at Imphal in northeastern India.
In the Battle of Hukawng Valley, Japanese Type 95 tanks of the 18th Division were joined by remnants of the 14th Tank Division. They were met with the offensive launched by the India-based Nationalist Chinese Army but the Japanese troops were virtually annihilated with the rest of the division as only 1,700 out of the 12,000 strong Chrysanthemum Division managed to break out.
When the M4 Sherman became available for the British to use in the North Africa campaign, they were able to transfer their M3 Medium tanks to India and Burma, which by then had become obsolete in the fighting in Europe, but the Type 95 was outclassed by these M3 tanks. When the war ended in 1945 and Japan capitulated, many Type 95s were left behind in China. They were used on both the Nationalist and Communist sides during the Chinese Civil War. After the Communists' victory in 1949, the Chinese People's Liberation Army continued to use them in their inventory.

Manchuria and the Kuril Islands

Although tank brigades equipped with the Type 95 were present during the 1945 Soviet invasion of Manchuria, the war ended before the Red Army had engaged their main formations. The only use of the Type 95 in any numbers against Soviet forces was at the Battle of Shumshu during the Invasion of the Kuril Islands, when shortly before the Japanese surrender had been finalized, they formed part of an armored force which unsuccessfully attacked the Soviet beach head, but was defeated by their anti-tank guns.

Usage after the war

Survivors

Although no surviving examples of the Type 95 light tank remain in Japan, a number have been preserved at museums around the world. In 2007, the Oregon Military Museum sponsored the complete reconstruction of a Type 95 light tank. The tank is no longer operational, however, as the original engine encountered mechanical issues and lost oil pressure during a test drive. A Type-95 in running condition is privately owned in the United Kingdom.
