Replica 7-Inch Gun
Replica 7-inch shells

Replica 7-Inch Shells at the emplacement. Copper studs are set into the sides of the shells. These studs engaged in the rifling of the gun barrel to impart a stabilising spin to the shells when fired.

This replica gun is mounted on a Garrison Carriage. This swivelled on a spigot fixed in the emplacement floor.

In 1891, it was reported that at this emplacement, the Cartridge Store had a capacity of 80 propellant cartridges, and the Shell Store had a capacity of 42 shells. The report continued to say that taking the side arm store into the shell store and removing the party wall would increase shell storage by an additional 49 shells.

The additional 7-Inch Gun Emplacement, later built on Mount Siloso (approximately where the No. 1 6-Inch QF Gun Emplacement now is) had storage for 220 propellant cartridges and 156 shells. About this was written, “This is 24 short of the complement but may be considered sufficient as in wartime a proportion should be permanently retained in recesses or the terreplein”. A terreplein is a flat platform situated behind a parapet on which guns are mounted.

7-Inch RML Guns were not highly regarded as they lacked the penetrating power and range required to engage enemy ships. On 9th June 1886, for example, Minutes on Departmental Papers of the Colonial Defence Committee noted: “With respect to the other points raised, it is to be observed that the W.O. authorities are quite well aware of the want of power of the 7-inch 6 ton gun....”.


Ammunition storage and an Ammunition Recess to the left of the Gun Emplacement. It is
possible that this was the Cartridge Store.


The replica 7-Inch RML Gun run out for firing. The replica is equipped with sound effects and a commentary which describes the loading and firing the gun. The gun emplacement would have been vulnerable to incoming fire from the west.


Replica Shells are to the left of the gun, and gun powder cartridges in protective cases are against the right hand side of the emplacement. Also seen are some handspikes on the right and a rammer on the left. This was used to ensure that the propellant charge and shell were pushed all the way down the barrel. A friction primer fired the gun. A gunner tugged on a lanyard which operated the primer. It took several minutes to load, train and fire the gun.


Storage and an Ammunition Recess, possibly for shells to the right of the gun.
