General info
The Army-Navy Model 3, or AN/M3 for short, was used by both the US Army Air Forces (later the USAF) and US Navy. The cannon was based on the British Hispano Mk.V, itself a modification of the Swiss Hispano-Suiza H.S.404. Compared to its earlier cousin, the AN/M2, the AN/M3 had a faster rate of fire and used lubricated, percussion-primed ammunition that was less prone to jamming, which was a major problem on the Hispano Mk.II. Lubrication was provided by a pump that dropped semi-fluid lubricating oil (LSA) onto the rounds before firing. The gun had a gas-assisted blowback operation, with recoil being used to load the next round.
The US Navy extensively used the AN/M3 on fighters starting in late WW2 and until the 1950s, when they were replaced by more modern cannons and air-to-air missiles. The cannon was mounted, usually 2 to a wing, on planes such as the F4U-4B and later versions of the Corsair, the Grumman F8F-1B Bearcat, and the F9F Panther jet fighter.

Comparison with analogues
- MG 151/20 - Powerful Minengeschoss shells are superior to AN/M3 ammunition. However, the AN/M3 has a faster rate of fire and better shell ballistics, making ranged shots and leading easier. The AN/M3 also has more hitting power as almost al American aircraft utilizing the AN/M3 have them in groups of 4. It is also more consistent than its German cousin, sparks are very rare. In addition, the AN/M3 cannons are far more accurate (when spaded).
- Hispano Mk.V- As the AN/M3 is an American copy of the Hispano Mk V, these two weapons are almost completely identical. Historically, the AN/M3 was more prone to jamming than its British counterpart, though in-game this is not the case and the AN/M3 does more damage, while being more consistent.
- AN/M2- Nearly identical characteristics, the only difference being the AN/M3 fires faster at 750 rounds per minute over the AN/M2, firing at 600 rounds per minute.
Usage in battles
The AN/M3 are good for engaging anything. These cannons come usually in groups of 4, allowing for a high burt-mass destruction. Powerful shells and great ballistics allow the pilot to take long range shots, cripple bombers and disintegrate all fighters in the opposing team. AN/M3s also come with generous ammunition reserves, great for taking down several enemies.
Pros and cons
Pros:
- Powerful cannon, a few shells are enough to cripple or disintegrate an enemy fighter
- Do not jam quickly, even when stock
- High rate of fire
- Often 4 cannons are present on the aircraft, providing massive firepower
- Stealth rounds have lots of HEF-I ammo, with the lack of tracers makes it hard for enemies to evade shots
- Often very generous amount of ammunition
Cons:
- Incredibly inaccurate when stock, shell spread is very noticeable
- Increased fire rate compared to its counterparts may deplete ammo reserves far faster
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. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />.
Media
Excellent additions to the article would be video guides, screenshots from the game, and photos.
