History BK 27 (also BK27 or BK-27) (German abbreviation for Bordkanone,
"on-board cannon") is a 27 mm (1.063 in)
In service 1977–present
The BK 27 (also BK27 or BK-27) (German abbreviation for Bordkanone, "on-board cannon") is a 27 mm (1.063 in) caliber revolver cannon manufactured by Mauser (now part of Rheinmetall) of Germany. It was developed in the late 1960s for the MRCA (Multi Role Combat Aircraft) program that ultimately became the Panavia Tornado. The BK 27 is a gas-operated cannon firing a series of 27×145 mm cartridges with a typical projectile weight of 260 g (9.2 oz), and a total weight for the complete round of 516 g (1.14 lb). 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

Operational history
In his book Typhoon, former RAF pilot Mike Sutton reported his 27 mm cannon jamming during a strafing run in Syria, against ISIS targets, while supporting Allied ground units. According to his book, the Typhoon was to be built, originally, without an internal gun, like the F-4 Phantom and the Harrier.
