Oboe was a British radar-based blind bombing system of the Second World War adopted by the RAF in 1942. It used two transmitters based in the UK; one tracked the bomber, guiding it on a course across the target. The other also tracked the bomber and ordered it to drop its bombs at the computed bomb-release point. Since accuracy was of a very high order, bombing became very accurate, and the system was used by the Pathfinder force to drop marker bombs for the rest of a bombing force. Research Oboe
