Virtual Discovery #79 - Understanding Significance

The 40 mm Bofors light anti-aircraft automatic gun was used extensively by military forces on both sides during WW2. It was developed by AB Bofors of Sweden in 1929. It was adopted by the British Army in 1938 as a point defence system against low level enemy attack. Mounted on a four wheeled trailer with deployable outriggers, it provided a mobile yet stable platform. It could fire a 1 kg projectile at a rate of 120 rounds per minute using 4 round clips. It had a maximum ceiling of 7,000 metres but was most effective below 3,800 metres.

The 40 mm Mk III Bofors gun Serial Number P10044 was manufactured with ingenuity and skill to defend Australia from enemy air attack during World War 2. During a time of threat, it formed part of the defences of Fortress Fremantle, including Rottnest Island, protecting the harbour, convoys and the submarine base. Operated by members of 116 Light Antiaircraft Regiment from 1942–45, it is now a memorial dedicated to their service and \to all who served in the defence of freedoms we enjoy today.
