Citat:Conclusion

As it can be seen from table, GIAT 30 is by far the best cannon when it comes to firepower, and combination of good muzzle velocity and projectile crossectional density results in good effective range. BK-27 has very good effective range thanks to high muzzle velocity and excellent projectile crossectional density, but limited (albeit still good) firepower. Russian guns also have good firepower and excellent projectile crossectional density but are let down by low muzzle velocity, suggesting an orientation towards the ground attack. US M61A2 has good muzzle velocity, but low crossectional density limits effective range, while low HE-I content and rotary design limit effective firepower. GAU-22/A has better HE-I content but less throw weight; still, good muzzle velocity and projectile crossectional density result in good effective range, though it may be limited by dispersion due to rotary design.

Since most important factors in gaining kills are mass of the projectile, HE-I portion, muzzle velocity and rate of fire, GIAT 30 is overall the most effective cannon when it comes to ACM (dogfight) employment. However, Rafale has a relatively limited number of gun bursts avaliable (adequate for a single kill). On face of it, best balance between number of gun bursts and their effectiveness seems to be achieved by Gripen and Typhoon. This may not be as great shortcoming on Rafale’s part, however, since GIAT 30 offers an option to reduce rate of fire to 1.500 rpm; this leads to 11 projectiles fired in first 0,5 s, weighting 3,03 kg with 0,529 kg of HE-I, allowing for a total of 11,4 bursts while achieving similar effectiveness to the BK-27 (and better than any other gun compared). Overall, European approach seems to be the most effective, with US sacrificing firepower, accuracy and response time in exchange for lower barrel wear and greater ammunition capacity, while Russians sacrificed muzzle velocity and HE-I content for greater round weight. This suggests that while European focus is on dogfight performance, US focus is on shooting down bombers while Russian focus is on ground attack performance.
