Anti-aircraft battery
A battery of guns usually, but could be rockets or missiles, designed to bring down hostile attacking aircraft. Such sites need not have been permanent, but of short duration. The plan of the battery can vary substantially - if a permanent site magazines, accommodation and sighting equipment would be required. Early AA-battery plans were scatter so as to limit damage by bombing, e.g. at Gloucester Lodge, south of Blyth, Northumberland. Later in World War II AA-batteries to counter the threat of semi-guided flying bombs (V1s) were arranged in rows to use accurate gun-laying radar, e.g. at Bridlington, North Yorkshire.
