Air Marshal Sir Kevin Leeson KCB, CBE, FREng (born 11 June 1956) is a retired British Royal Air Force engineer officer who attained the rank of chief of defence materiel (Air).
Since leaving the Ministry of Defence in 2012 he has pursued a new career in the arms industry.

MOD access passes
In October 2017 a freedom of information request by Campaign Against the Arms Trade revealed that both Airbus and Atkins staff held passes (7 and 2 respectively) which allowed them access to the Ministry of Defence buildings in Whitehall. It is not known whether Leeson was among those who hold these passes. Other arms trade companies with such access included Fujitsu (50 passes), BAE (19), PA Consulting (15) and Leonardo (13).
