-The '''20 mm/70 Oerlikon Mark 24 (20 mm)''' is a rapid-fire, anti-aircraft cannon that was developed in the 1940s by the Swiss company Oerlikon. This weapon system is a modification of the earlier Mark 4 and Mark 20 models, and it features an improved rate of fire, better accuracy, and a more efficient cooling system. The Mark 24 cannon has been widely used by the United States Navy and other navies around the world, and it has proven to be a reliable and effective weapon system in combat.
