OBOE originally used two ground stations, code named "cat" and "mouse", to guide a single aircraft to its target. This plane (usually a Mosquito bomber) would guide a large number of heavy bombers (such as Lancaster bombers). Both radar mechanics and WAAF operators worked on these ground stations. OBOE was used to guide bombers to their targets, and was accurate to within 100 meters up to 400km away! Later, OBOE was also mobile and was brought onto the continent in truck convoys on D-Day. Its accuracy was also useful after the liberation of areas such as the Netherlands, when many people were without access to food and water. Operation Manna used OBOE radar to coordinate the dropping of food and supplies directly to the areas that needed them most.
