<p>A Quick Fire (QF) 4 inch Mk.IV naval gun on a pedestal mount at Ordnance Point, East Falkland. The gun has a range of 10,200 yards (9.3 km) and a rate of fire of 15-20 rounds per minute with an experienced crew.
</p><p>In the 1942 Ordnance Officers report form the Falkland Islands, Ordnance Point was the site of a 3 pounder battery, but future work recommended the re-siting of the 4" gun on Mount Low. This was dependant on two additional 6" guns being delivered to the islands. This will have taken place in 1943 at the earliest, and so this may be the date of installation of the gun at this point.

Also in the 1942 works report, an engine house and concrete bed for a Defence Electric Light (DEL) had been constructed, but not completed. Foundations of these buildings may remain on the headland.
