General info

Flight performance

This Zero is very similar to its predecessors, albeit slightly faster. It is still as maneuverable as ever.

Survivability and armour

Examine the survivability of the aircraft. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armoured, etc. Describe the armour, if there is any, and also mention the vulnerability of other critical aircraft systems.


Offensive armament

The A6M5 Ko is armed with:

  • 2 x 20 mm Type 99 Model 2 navy cannons, wing-mounted (125 rpg = 250 total)
  • 2 x 7.7 mm Type 97 navy machine guns, nose-mounted (700 rpg = 1,400 total)

Suspended armament

The A6M5 Ko can be outfitted with the following ordnance:

  • Without load
  • 2 x 60 kg Navy Type 97 Number 6 bombs (120 kg total)
  • 1 x 250 kg Navy Type Number 25 Model 2 bomb (250 kg total)

Usage in battles

At this rank, the Zero is outclassed by everything it faces. The only thing left to hang on to is its famous maneuverability. More than ever, the key is to exploit its nimbleness to force the enemy to make mistakes. Every single aircraft in this battle-rating is far faster - the P-47N-15 is nearly 200 km/h faster! Given the inferiority of your aircraft, it is not common to see enemies in tight places just make a break for it - if you don't catch them, they're gone.

The Zero's infamous reputation as a funeral pyre for its pilots continues - there is still a lack of armour, meaning if you're hit, it's likely fatal. This means you need to dodge all the shots. Remember to turn into the enemy to spoil their aim. Your only hope of destroying an enemy is to enrage them and make them dogfight the Zero. Then, it's a simple matter of getting onto their six and lighting them up. You cannot be too aggressive in the Zero - your goal is to remain alive and frustrate your enemies.

Pros and cons

Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".


  • Effective at altitudes below 6,000 feet (1,800 meters)
  • Type 99 Model 2, 20mm cannons do considerable amount of damage to all aircraft .
  • Type 97 Machine guns have a fast velocity with an abundance of ammo allowing for easy ranging in RB and SB without need to regulate the ammo.
  • The high torque engine and low weight of the aircraft allow for exceptional turning radius fast rate of climb, and above average stall recovery for even the newest of pilots.
  • The A6M5 KO platform rewards the pilot who can use tactics such as Yo-Yo's and Immelmann's and allows newer pilots to perform advanced maneuvers above their skill.


  • Ineffective above 10,000 feet (3,000 meters)
  • Slower than nearly any other aircraft making you the one being attacked more often then you attack others.
  • The plane is fragile compared to others at it's tier and prone to catching on fire.
  • Newer pilots who do not have defensive skills can find the plane frustrating due to it being vulnerable to faster planes that "boom and zoom".
  • The Type 97 Machine Guns lack damage, newer pilots who do not have cannons and machine-guns bound to different buttons will run out of cannons quickly and be left with a plane that cannot reliably damage enemies.


Describe the history of the creation and combat usage of the aircraft 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 vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />.

In-game description

Mitsubishi Type 0 Model 52 "Kou" (A6M5 Model 52a, reporting names: Zeke/Hamp/Zero) single-engine carrier-based fighter

In the middle of 1942, the Allies in the Pacific Ocean Theatre took the offensive, while the Japanese were more and more often on the defensive. In 1943, new types of high-speed fighters entered service with the USAAF and the USNAF, and they outperformed the Zeros in many respects. Low survivability, the main disadvantage of the Japanese aircraft, was made clear in the fierce air duels between the planes. The fighter's flight characteristics also required some improvement, and Mitsubishi Heavy Industries designers began to upgrade the A6M again in August 1943.

The Zero received a smaller-area wing (with a span of only 11 m) with rounded tips. The wing folding mechanism was removed. To increase the plane's allowable diving speed, its wing surface skin was reinforced.

Since more powerful engines were not yet available, the designers had to make the most of a Nakajima Sakae 21 engine. Every pair of cylinders was given an individual exhaust pipe instead of a common heavy exhaust manifold. This added exhaust gas thrust to the propeller thrust, which resulted in a higher aircraft speed. The fuselage skin had to be reinforced with steel sheets in the area of the pipes, since the hot exhaust gases quickly burned through thin duralumin.

The new version of the aircraft was designated Model 52 (A6M5 Model 52). The plane became slightly heavier, but its maximum speed at a height of 6,000 m reached 565 km/h. This was the speed limit for the Zero, since all further modifications made to the machine only increased its weight and, consequently, reduced its maximum speed.

The next stage in upgrading the Zero was the Model 52 "Kou" (A6M5a Model 52a). This improvement significantly reinforced the plane's armament by replacing the wing-mounted Type 99-2 Model 3 drum-fed cannons (with 100 rounds each) with Type 99-2 Model 4 belt-fed cannons (with 125 rounds). This added 25 rounds per cannon and slightly improved the plane's rate of fire. Now the fighter's armament consisted of two synchronous 7.7 mm Type 97 machine guns with 500 rounds each plus two wing-mounted 20 mm Type 99-2 Model 4 cannons with 125 rounds each.

The A6M5a fighter could carry bombs: two 60 kg (132 lb) bombs suspended under the wing and one weighing 250 kg (551 kb) under the fuselage.

In addition, the A6M5a's wing structure was reinforced yet again, which resulted in a maximum allowable diving speed of 740 km/h. However, this was still inferior to the diving speed of the American F4U fighter.

Mass production of the A6M5a variant began in March 1944. Mitsubishi Heavy Industries manufactured 391 machines. An additional unknown quantity of this variant was built by Nakajima Aircraft.
