During the Second World War, Bronowski worked in operations research for the UK's Ministry of Home Security, where he developed mathematical approaches to bombing strategy for RAF Bomber Command.
At the end of the war, Bronowski was part of a British team of scientists and civil engineers that visited Japan to document the effects of the atomic bombings of Hiroshima and Nagasaki for the purpose of studying the effects of the atomic bomb and its implications for future UK civil defence. Bronowski, in conjunction with Professor W. N. Thomas of the University of Cardiff, subsequently produced the secret "Report of the British Mission to Japan on an Investigation of the Effects of the Atomic Bombs Dropped at Hiroshima and Nagasaki" which was passed to various government departments and consulted in the design of future UK public buildings.
