The ballistically illiterate often think that a small calibre rapid firing cannon is what is needed for engaging aerial targets,which is the opposite of the truth as smaller projectiles tend to have a longer time of flight and generate a smaller effective volume than larger ones,but to compensate for the inherent inadequacy of the 57mm Bofors 57 Mark 3 Naval Gun System there is a transformational cartridge incorporating a guidance sytem called the Advanced Low-Cost Munitions Ordnance (ALaMO),unfortunately each one costs sixteen times more than a High Explosive Point Detonating round,seven times more than a 3P Mark 295 cartridge and about five times more than a 5 inch Mark 187 High Explosive projectile with a Mark 419 Multi-Function Fuze and full propelling charge,and firing two hundred and twenty rounds per minute at a suicide boat swarm attack would cost almost one hundred thousand pounds per second.
