Armament

Since the area was first used as a Fort for the protection of the coastline and harbour, there have been many changes to the armament used within the Fort.

• The guns used at the Fort have included:
• The 20-Pounders (Muzzle Loaders) in 1804
• The 32-Pounders (Muzzle Loaders) up to 1840's
• The 68-Pounders (Muzzle Loaders) in 1867
• The 80-Pounders (Muzzle Loaders) in 1878, originally above ground then in installed in the Casemate area (underground)
• The 9-inch Muzzle Loaders installed in 1882
• The 6-inch Armstrong (Breach-Loader) Disappearing Guns in 1892
• Three 1.5-inch Nordenfelt Guns by 1892 in the Casemate (replacing the 80-Pounders), with one at Torpedo Point on the harbour near the Pilot Station, one installed at Fort Scratchley above the western Barbette
• The 80-Pounder removed from the Western Barbette in 1907
• One 1.5-inch Nordenfelt gun removed from No.1 casemate and the emplacement converted for use as a magazine in 1911, one 6-inch Mk V disappearing gun removed from service and two 6-inch Mk VII guns installed as the main armament in 1911. These guns are still in place today, and are fired for special events.
• Two remaining 1.5-inch Nordenfelt removed from service and returned to Sydney in 1918
• Two remaining 6-inch disappearing guns removed from service after the end of World War 1
