Bofors 40mm Anti-Aircraft Gun
Canadian warships sent to the Persian Gulf received anti-aircraft guns on mountings like these to improve their defences.
A gunner (centre left) aims and fires the weapon, while a loader (centre right) loads clips of ammunition from racks (right) into the gun (left). Seen here on a power-driven "Boffin" mounting, the 40mm Bofors anti-aircraft gun first saw extensive use during the Second World War, and remained widely used afterwards. HMCS Protecteur, the supply ship deployed to the Gulf in August 1990, received two such weapons, originally from the aircraft carrier HMCS Bonaventure which had been decommissioned some 20 years earlier.
