In 1969 a new Defence Scientific Advisory Council was constituted to provide the Secretary of State for Defence with independent advice on research and development activities within the Ministry of Defence. Bullard accepted an invitation to serve on the Undersea Warfare Board. In 1972 the Undersea Warfare Board was merged with the Ships Board to form the Maritime Warfare Advisory Board and Bullard agreed to serve on the new board. Also in 1972 he accepted an invitation to serve on a working party on Maritime Air. He resigned from the Maritime Warfare Advisory Board at the end of 1974 because he was going to spend most of 1975 in the USA.
