== 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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: <nowiki>https://wiki.warthunder.com/(Weapon-name)/History</nowiki>) and add a link to it here using the <code>main</code> template. Be sure to reference text and sources by using <code><nowiki><ref></ref></nowiki></code>, as well as adding them at the end of the article with <code><nowiki><references /></nowiki></code>.'' -->
In the late 1960s, the British, West Germans, and Italians collaborated on the Multi-Role Combat Aircraft (MRCA) program to create a jet that would serve as their needed counter to the Soviets MiG-25 "Foxbat" and Su-15 "Flagon". The result was the [[Tornado (Family)|Panavia Tornado]], and the aircraft needed a cannon. Mauser stepped up to the plate and created the Mauser BK27 (Bordkanone, meaning "on-board canon"). Mauser's creation of this weapon is not a surprise as the first modern revolver cannon was also developed by Mauser. The MK 213 was developed during World War II, but it never saw combat. After the war, Mauser was disbanded (it was re-established in the 1950s due to the need to supply the recently formed Bundeswehr of West Germany) and the designers soon left for greener pastures in the US, UK, France, and Switzerland and took the designs with them. From this designer exodus, the [[M39A1 (20 mm)|M39]], [[ADEN (30 mm)|ADEN]], [[DEFA 551 (30 mm)|DEFA]], and Oerlikon KCA cannons were born.

The BK 27 fires a 27x145 mm cartridge developed by Mauser and is a gas-operated action. Along with the Panavia Tornado, the BK 27 was also mounted on other European aircraft. These aircraft include two additional international joint venture aircraft. The French-West German Dassault/Dornier Alpha Jet uses the BK 27 as does the Swedish SAAB JAS 39 Grippen and the Eurofighter Typhoon. Typhoon notably uses a linkless feed system for the BK 27 to improve reliability. It is also the basis for remote-controlled weapons stations used by the Deutsche Marine (German Navy).
