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.

Armaments

Suspended armament

Main article: Suspended armaments

Usage in battles

Describe the tactics of playing in an aircraft, the features of using vehicles in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

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".

History

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: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 />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

In-game description

A quad-engined all-metal parasol-wing monoplane flying boat. An experimental version, the Type S, made its first flight on July 14, 1936. The plane was approved by the Imperial Japanese Navy as Type 97 Large Flying Boat in 1937. Mass production began in 1938.

The most common variant was model 22 (H6K4), created in 1940. The first 119 planes were fitted with a air-cooled 14-cylinder twin-row radial Mitsubishi Kinsei 43 engine (1000 hp). Afterwards, the slightly more powerful Kinsei 46 was used. The H6K4 carried more fuel than earlier models, increasing its maximum range to 25 hours, or 6000 kilometers. Its fuselage included waist blisters fitted with machine guns, which required a slightly longer tail section.

The H6K4 was armed with four 7.7mm Type 97 (Lewis) machine guns with 582 rounds apiece and, in the tail turret, one 20mm Type 99-I cannon with 432 rounds. The flying boat could carry twelve 60-kg bombs, four 250-kg bombs, or two 800-kg Type 91 Model 1 torpedoes.

A major weakness of all H6K flying boats was the lack of protective armor for the crew and for the fuel tanks. This was sacrificed for the sake of its extended flight range. When the plane started to suffer losses in combat, designers of later Model 22 planes began to focus on protecting the crew.

The H6K flying boat's first combat action was a raid on Wake Island on December 11, 1941. The plane was widely used in the Pacific theater during the first part of the war. The H6K ran long-range reconnaissance missions, convoy escort duty, submarine searches, bombing missions, and search and rescue operations. When the newer H8K arrived, the H6K began to be used mostly as a transport plane. The plane was in operation until the Japanese surrender in 1945.

127 H6K4s were built, out of a total of 217 H6Ks.

Excellent additions to the article would be video guides, screenshots from the game, and photos.
