North Head Gun Emplacement
About the building
During WWII, North Head was one of the most heavily fortified sites in Australia. Two heavy 9.2 inch calibre guns were positioned in Gun Emplacements 1 and 2 as part of North Head Battery. The guns were connected by underground tunnels and were prepared to fire on enemy ships or inland targets. Gun Emplacement 2 was the North, or No. 2 gun, of the Battery. This emplacement, just like its No. 1 counterpart, had a round concrete upper gun floor, with a central pit containing the pedestal for the mounting of the gun itself. Underneath the gun floor, the Shell Store was built to hold up to 250 TNT-filled shells – each weighing 172 kg.
These enormous guns had a firing range of more than 28 km at maximum charge (that’s the distance from Manly to Palm Beach), with a rate of fire of two rounds per minute. Primary targets were ships at sea, but secondary landward targets - such as road junctions, bridges and significant landing points - were also designated in the event of a successful enemy landing and subsequent overland attack.
