<p>A weapon system (10) comprises: a barrel (12) for accommodating a projectile (14) in a breech end portion (16); a muzzle end portion (18) and a breech (20). The weapon system further comprises means for purging the barrel comprising a coanda slot (22); a soanda profile (24) provided downstream of the coanda slot; a source of pressurised gas (26); a duct (28) which connects the source of pressurised gas to the coanda slot (22) so that pressurised gas can be selectively supplied to the coanda slot (22) and along the coanda profile (24) thereby entraining air in the barrel (12) and exhausting debris and/or fumes through the muzzle end portion (18) after firing of a projectile (14); and a valve (30) for controlling flow of gas through the duct (28).</p> |
