Graemsay Battery
Image information
Description
In WWII Graemsay Battery was armed with a twin six-pounder gun. It provided anti-MTB defence for Hoy Sound. It was originally emplaced at Northfield on the north end of Burray, but was moved to Graemsay in 1943 after the construction of the Churchill Barriers made the presence of anti-ship defences unnecessary there.
The gun was mounted before the end of 1943, but was not fully operational until March 1944.
The twin-six pounder could fire 72 rounds per minute and was designed to take on fast moving craft such as MTBs or 'E'-boats.
The nearby searchlight emplacements housed four 15kW Fortress Mk VI projectors which emitted dispersed beams, overlapping to form an illuminated area between bearings 220 and 320. There were further lights along the shore near Stromness to the north and at Skerry Battery on Hoy to the southwest, and between them they would have been capable of turning night into day should any hostile vessel try an attack.
With another twin-six at Links Battery, the two six-inch guns at Ness and the pair of 12-pounders at Skerry, a vessel trying to enter through the Hoy Mouth would come under a combined fire of around 190 shells per minute.
