Mauser BK 27 27mm Cannon
This 27mm cannon is a single barrel, gas-operated lightweight single barrel revolver cannon that fires electrically primed 27x145 mm ammunition at 1 700 rounds per minute.
Developed by Mauser-Werke Oberndorf of Germany, it's features include low volume, low system weight, high fire power in target (air/air, air/ground), low time of flight projectile and a long stand-off range.
The cannon is relatively lightweight at only around 100 kg including barrel, but with a natural rate of fire of approximately 1700 rounds per minute (instantaneous time to rate), the relatively large shell (260g) and the high muzzle velocity of just over 1 km/s (v0) it packs a punch. The cartridge is ignited electrically and fed to the cylinder through linked belts or, in the case of the Eurofighter, through a linkless conveyor belt ammunition feed system, the first such system for revolver guns. Linkless systems (which are a staple in modern Gatling-type cannons) are less prone to stoppage and the ammunition uses considerably less space.
The different types of ammunition all have the same internal and external ballistic properties allowing for the use of belts with mixed ammunition for greater flexibility.
