During the Second World War, Wormshill joined a number of similar settlements in the region to form part of the anti-invasion network. On the outskirts of the village, near the hamlet of Ringlestone, there are the remains of a "zero station" (or "Operational Base"), a secret underground communications relay post operated by Auxiliary Units of the British Home Guard. In the event of a German invasion the zero station was to be used by defending forces to receive and transmit coded messages between a series of similar stations in the area as well as to the operational command headquarters at Hannington Hall in Wiltshire. A concealed underground concrete bunker, it was designed to be invisible from the surface and is located in woodland about from the road. Although its primary purpose was a communications post, the zero station was also designed to hold ammunition and explosives and provide living quarters for the radio equipment operators. Anecdotal evidence also indicates that anti-aircraft guns were sited near the village and that a Bren gun emplacement was installed in the valley between Wormshill and Frinsted. A Diver Battery was located to the south west of the village. Forming part of the Kentish Gun Belt, designed to provide a defence to attacks by V-1 flying bombs or "doodlebugs", it was armed with eight mobile 3.7-inch guns, and manned by 424 Battery of 138 Regiment of the 40th Anti Aircraft Brigade. It was initially equipped with Predictor AA No.10 and No.3 Mark V radar, and was manned by 57 Brigade in July 1944. There are records of a V-1 being shot down by a Supermarine Spitfire to the west of the village. Flt Lt A. R. Cruikshank is reported as having "Sited a Diver north of Ashford and attacked from astern at 100 yards range. Saw strikes and Diver fell and exploded in a field". Villagers resident during the war also recall a V-1 being shot down in orchards near "Norwood Farm" and a fighter aircraft crashing in fields to the south of "Yew Tree Farm". Roadside checkpoints were set up on the main routes into the village to the north and south and allied forces moving through the region camped overnight in the area, including a detachment of New Zealand troops in fields near "Home Farm".
