The M230 Chain Gun is the Area Weapon System on the AH-64 Apache attack helicopter and is also used on the MH-60L Direct Action Penetrator (DAP). The M230 is mounted on the chin turret. It uses a 2 hp electric motor to fire 30 mm linkless ammunition at a rate of 625 (±25) rounds per minute. The gun requires a spool-up time of 0.2 seconds to achieve this rate of fire. The practical rate of fire is about 300 rounds per minute with a 10 minute cooling period as the gun is air cooled. [3] The gun has a positive cook-off safety for open bolt clearing, and double ram prevention. Spent casings are ejected overboard through the bottom of the gun.
