Mount Faber Command Center

Beneath Mount Faber in Singapore lies the Faber Fire Command Fortress Plotting Room, a subterranean complex built in 1936. It was used to receive information about naval targets from observation posts, plot the information, and extract the required data to act upon.

There were two Main Fortress Plotting Rooms in Singapore and each Counter Bombardment gun battery had a Battery Plotting Room. The concrete-lined access passageway was likely a secondary or emergency exit. The Fortress Plotting Room contained equipment such as Range-finding Exchange, Fortress Plotters, Fall-of-Shot Indicators, Fire Direction Table, and Ballistic Correction Calculators. The Fall of Shot Encoder enabled the Fortress Plotting Room to take fall of shot observations from two Fortress Observation Posts and convert them into Clock Code. Australian coast defences used Women’s Services to work in the plotting rooms and observation posts.

It was believe to have been used in the during the occupation and was mention in the report.

There are currently believed to be 7 Main and Battery Plotting Rooms in Singapore for the defense of Singapore, but they are not open to the public. However, efforts are being made to improve public participation, and it is believed that the Mount Faber command center will eventually be opened to the public.
