The Lascaris War Rooms contained operations rooms for each of the fighting services, from where both the defence of Malta and other operations in the Mediterranean were coordinated. The Operation Headquarters at Lascaris communicated directly with radar stations around the Maltese islands, and it was equipped with Type X machines. The fleets were led from the Navy Plotting Room, while the Anti-Aircraft Guns Operations Room was responsible for the air defence of the island. In the Coast Defence Room, defensive operations in the case of an amphibious invasion were planned. The Filter Room displayed information received from various places, including the naval station at Auberge de Castille.
