<!-- ''Write an introduction to the article in 2-3 small paragraphs. Briefly tell us about the history of the development and combat using the weaponry and also about its features. Compile a list of air, ground, or naval vehicles that feature this weapon system in the game.'' -->
The Experimental High Velocity, otherwise known as the Type 5 is currently the most powerful gun mounted on an IJA tank in War Thunder. It draws parallels to the famed German 88 mm [[KwK43 (88 mm)|KwK43]], sporting similar muzzle velocity and penetration, but with significantly increased explosive filler and improved angled armour penetration. Players who are used to the KwK43 will find themselves right at home when using the Type 5.

== General info ==
<!-- Tell us about the tactical and technical characteristics of the cannon or machine gun. -->

As mentioned previously, the Type 5 is very similar to the widely used German [[KwK43 (88 mm)|KwK43]], trading raw flat penetration in favour of explosive filler and improved angled armour penetration. However, it is important to note that the drop in penetration is quite minor at traditional combat ranges but becomes significantly more drastic beyond 1,000 m. Regardless of the drops in penetration, many players seem to say that the Type 5 is superior as a result of its significantly better angled armour penetration and its higher explosive filler. If a Type 5 penetrates, it will almost always destroys the target. The cannon itself favours a sniper play style, as it can shoot down enemies at range with little worry of follow up shots thanks to the high explosive filler.

However, the cannon is plagued by relatively poor penetration compared to other guns at its battle-rating. During the shift into Rank V, most tanks will be running APDS or HEAT rounds with far superior penetration and muzzle velocity, and more tanks will be fitted with significantly better armour effectively thwarting most attempts at frontal penetration. Though with the prototype sporting slightly weaker armour and a lower velocity cannon than its finished production stage, it will encounter these problems less frequent.

=== Available ammunition ===
<!-- ''Describe the shells that are available for the weapon and their features and purpose. If it concerns autocannons or machine guns, write about different ammo belts and what is inside (which types of shells).'' -->

* '''Type 2 APHE:''' {{Annotation|APHE|Armour-piercing high explosive}} - The Type 2 one of the two standard rounds of the Type 5. This round can be used against nearly all kinds of medium or heavy tanks and is thank to its massive high-explosive filler capable of destroying most of its targets with only one shot.
* '''Experimental HE:''' {{Annotation|HE|High-explosive fragmentation}} - Standard HE shell with higher than average penetration, useful to bring along to deal with lightly armoured vehicles such as the Italian APC's and American late light tanks.

=== Comparison with analogues ===
<!--Give a comparative description of cannons/machine guns that have firepower equal to this weapon.-->
* [[KwK43 (88 mm)]]: German equivalent 
* [[D-10T (100 mm)]]: Russian equivalent
* [[M3 (90 mm)]]: American equivalent
* [[20pdr OQF Mk.I (84 mm)]]: British equivalent

== Usage in battles ==
<!-- ''Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against notable opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.'' -->
The Type 5 should be primarily used as a sniper due to its high velocity and excellent penetration at range, but also due to its slower reload. The Type 2 should be the go-to shell for most targets, but it is important to bring a few HE shells to deal with the previously mentioned light tanks.

=== Pros and cons ===
<!-- ''Summarise and briefly evaluate the weaponry in terms of its characteristics and combat effectiveness. Mark pros and cons as a list.'' -->

'''Pros:'''

* High amount of explosive filler on its APHE shell, results in a lot of one-shots
* Very accurate with little shell drop
* Solid penetration
* HE shell has 30 mm of penetration all-around and a '''lot''' of explosive filler, easy to destroy light tanks with
* Arguably one of the best firing sounds in the entire game
* Not a lot of recoil, easy to follow up shots

'''Cons:'''

* Relatively slow reloading rate
* Penetration can be underwhelming when facing higher-ranked vehicles
* Cannon barrel and breech are quite fragile
* Fuse sensitivity on APHE leads to the shell going right through some lightly-armoured tanks

== History ==
<!-- Examine the history of the creation and combat usage of the weapon 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 weapon and adding a block "/History" (example: https://wiki.warthunder.com/(Weapon-name)/History) and add a link to it here using the main template.

In 1942, Japan realized they were falling quite behind in terms of tank production as news of the American M6 and M26 heavy tanks reached the high command, leading them to redesign their tank production to become more like Germany's, meaning new tanks designed to be made with high powered tank guns. This lead to the [[Type II Model II (75 mm)|75 mm Type II cannon]] mounted on the Chi-To, Chi-Ri and variants of the Chi-Nu, and the '''105 mm Type 5'''.

The Type 5 was designed off of the old Type 96 150 mm strategic artillery cannon, which was deemed to have the most potential for a downscaled tank gun. It was shortened, given a single piece barrel and was applied with a tank breech. The experimental cannon was completed in December 1944 with tests following in March of 1945. After showing promising performance outclassing most tank guns at the time, two prototype guns were made for the Ho-Ri, one for the tank itself and another for external testing until the next tank was completed. The end of the war terminated development but several promising designs were based around the gun; a development of the Na-To tank destroyer titled the Ka-To, a heavy-medium tank with the chassis of a Ho-Ri and the turret of a Chi-Ri with additional armour named the Chi-Se.
