Ranges are taken from Records in the British National Archives. The ammunition listed for each gun was kept in the gun’s magazine. Additional ammunition was stored in a reserve magazine. One such reserve was on Mount Imbiah on Blakang Mati.

Note: The Sphinx 6 Inch Battery's Mark 24 guns had a 45° elevation compared to the 14° elevation of Mark VII Guns at all other 6 Inch Batteries.

Penang was defended by two Mark VII and two Mark 24 6 Inch BL Guns. An emplacement for two 9·2 Inch BL Guns had been constructed, but was unarmed when the war with Japan began.
