After the outbreak of the Second World War, Adams was assigned to the destroyer. On 11 September 1939, Walker ran down and went through her sister ship,, and was jammed in her. As the weather and conditions were good, both ships were able to be saved. During the crisis, Adams carried Vanquishers safe with its confidential material inside to the deck of Walker, but found that after the situation had calmed down the next morning that he was unable to lift it. He served on the in 1941 and saw action in the Western Approaches of the coast of Great Britain, as part of the St. Nazaire Raid and the landings of Allied troops in North Africa and Sicily. He underwent training and qualified as a torpedo and electrics specialist in 1943, and was able to use this knowledge to prepare escorts for convoys crossing the North Atlantic. On 15 December 1942 he was Mentioned in Despatches for his actions aboard Cleveland in an engagement with E-Boats. After the war, he commanded the destroyer and served in the Admiralty's torpedo and anti-submarine warfare division, among other staff appointments. He was promoted to lieutenant commander on 1 June 1948, and commander on 31 December 1950. He was then given command of the Royal Yacht Britannia, which included taking Princess Margaret to the West Indies, Queen Elizabeth II to Portugal and a world tour for Prince Philip, Duke of Edinburgh, serving from 1954 to 1957. As a result, he was appointed a Member of the Fourth Class of the Royal Victorian Order in the 1957 Queen's Birthday Honours. He was promoted captain on 31 December 1956. Adams commanded from May 1964 to January 1966. The ship was deployed in the Indian Ocean and the Far East. She arrived east of Suez with 848 Naval Air Squadron and a strong force of Royal Marines. During the Indonesia–Malaysia confrontation, Albion sent two flights of Wessex helicopters to support marine and army border patrols from bases in Borneo and Sarawak. He was promoted rear admiral on 7 January 1966. In 1966, serving as Assistant Chief of Naval Staff, Adams was assigned to the Ministry of Defence and became chairman of the Future Fleet Working Party, reporting to Admiral of the FleetSir Varyl Begg. Building on his experience with the Albion, Adams' working party recommended a "through-deck cruiser" that would carry vertical take-off jet fighters and deploy helicopters, insisting that this approach was the logical conclusion of his research. Begg, who believed that missiles would replace planes, exploded with anger and rejected Adams's report publicly. Begg told him that he would never be employed again. Adams retired on 12 February 1968, and was appointed a Companion of the Order of the Bath in that year's Queen's Birthday Honours, but was invited to the launch of the aircraft carrier in 1977, which was a vindication of his approach.
