context_page_description: The BK 27 is a 27 mm caliber revolver cannon manufactured by Mauser of Germany. It was developed in the late 1960s for the MRCA program that ultimately became the Panavia Tornado.
  The BK 27 is a gas-operated cannon firing a new series of 27×145 mm cartridges with a typical projectile weight of 260 g, and a total weight for the complete round of 516 g. Most models use a linked feed system for the ammunition; however, the Eurofighter Typhoon makes use of a specially developed variant of the BK 27 that uses a linkless feed system instead, which is intended to improve reliability.
