Abstract
A weapon system comprising a barrel for accommodating a projectile in a breech end portion, a muzzle end portion and a breech. The weapon system further comprises means for purging the barrel comprising a coanda slot, a coanda profile provided downstream of the coanda slot, and a source of pressurized gas, a duct which connects the source of pressurized gas to the coanda slot so that pressurized gas can be selectively supplied to the coanda slot and along the coanda profile, thereby entraining air in the barrel and exhausting debris and/or fumes through the muzzle end portion after firing of a projectile, and a valve for controlling flow of gas through the duct.
