In late 1939, at the beginning of World War II, the 8th Anti-Aircraft Battery placed some machine guns on the upper level of the tower. In August 1941 a two-storey concrete structure was placed on top of the tower to enable the tower to function as a Fire Command Post, in which role it remained until August 1944. On 20 April 1942 the tower received a No. 3 Mark 4 telescope and a No. 10 Director.[clarification needed ] On 1 May 1943 a Mark II Position Finder was added to the fire control equipment on the tower. Soldiers of the 3rd New Brunswick Coast Brigade manned the tower from 1941 until it ceased operations in 1944.[5]
