Mauser BK-27

The Mauser BK-27 is a 27 millimeter revolver cannon developed by Mauser in Germany. It was made in the late 1960s for the Multi Role Combat Aircraft (MRCA) program. The BK-27 has a high muzzle velocity and link-less feed system and can fire at either 1,000 or 1,700 rounds a minute, which is good, but not nearly as fast as the M61 Vulcan. It has a very good hit-accuracy and the targeting is done in the aircraft’s HUD (Head-Up Display). Also, it has the ability to fire several different types of shells, which makes it good for both aerial and ground attacks.
