A revetted slit trench and a weapons pit of Second World War date were visible as earthworks in RAF/HLA/564 V 6029 01-JUN-1942. These components of defences protecting the east flank of RAF Manston were positioned in the south-east corner of the airfield. They were removed during the construction of RAF Manston's crash runway in 1943-44.

These features were recorded as levelled earthworks in Next Perspectives APGB Imagery 07-APR-2021 and were mapped as part of the Historic England Isle of Thanet project in 2024. (1-2)
