Lists on the subject

The BK 27 is a revolver cannon manufactured by Mauser , now part of Rheinmetall . BK 27 stands for B ord k anone in the caliber of 27 mm. It was developed in the late 1960s for the MRCA ( Multi-Role Combat Aircraft ) program, which resulted in the production of the Panavia Tornado .

Mauser BK-27

The Mauser BK 27 is used in the Panavia Tornado , the Alpha Jet , the Saab 39 Gripen and the Eurofighter Typhoon , for which an improved version with higher reliability was developed. At times the US Air Force planned to acquire the license to produce the cannon for the F-35 , the Joint Strike Fighter , but abandoned this project in favor of the GAU-12 .

Aside from being used in combat aircraft, there are maritime versions, such as the MN 27 GS and MLG 27 , which are used as light ship guns.

Comparison with Gatling cannon

Compared with Gatling guns of such M61 Vulcan , the higher cadence firing, wherein short bursts up to one second, as they occur in combat situations, the number of fired projectiles per volley in the Mauser BK 27 is greater than that of the Gatling guns . The reason for this is that the mostly electrically driven barrels of the Gatling cannons only reach their full speed after a short start-up time. With the BK 27, however, the full rate of fire is available from the first shot. Because of this and the larger caliber, it can fire projectiles with a total mass of just under 4 kg in the first half a second, while the M61 is around 2 kg.
