In September 1939 Maidstone was Depot Ship to the ten submarines of the 1st Submarine Flotilla. In March 1941 she went to Gibraltar. From November 1942 Maidstone was based at Algiers Harbour now the main Allied base in the Mediterranean. In November 1943 she went to the Eastern Fleet. In september 1944 Maidstone and the 8th Submarine Flotilla were transferred from Ceylon to Freemantle in Western Australia to operate in Pacific waters. Late 1945 Maidstone left Fremantle, and en-route to UK the submarine depot ship was docked in the Selborne dry dock at Simonstown, South Africa. Whilst on passage, she was diverted to Macassar to pick up 400 British naval prisoners of war from HMS Exeter, HMS Encounter and HMS Stronghold. In November she arrived at Portsmouth.

1946 Maidstone became mother to the 2nd and 7th, Submarine Flotilla. The 2nd Flotilla comprised operational boats, the latter was specifically a trials and training squadron. Maidstone had a semi-permanent mooring off Monkey Island (Portland) but often put to sea with her brood. In 1951 Maidstone called briefly at Corunna to land a sick rating, but this was not classified as an official visit, although it was the first time a British ship had entered a Spanish harbour since the Spanish Civil War. On 16 June 1955 the submarine HMS Sidon sank in Portland harbour alongside Maidstone twenty minutes after an internal explosion had occurred in the forward torpedo compartment. 13 men lost their lives. A week later, the submarine was raised and the accident was found to be caused by an explosion of the high-test peroxide fuel used in a torpedo. In 1956 Maidstone was the Flag Ship of the C in C Home Fleet. In September 1957, the Russians protested when Maidstone accompanied by the training aircraft carrier HMS Ocean visited Helsinki. In 1959 Maidstone received an extensive refit, allowing her to accommodate nuclear submarines, the 2nd Flotilla was then moved to Devonport. In October 1969 Maidstone was restored and re-commissioned as an accommodation ship for 2,000 troops and sent to Belfast. She arrived under tow at Belfast to serve as barracks for the increased security forces in the area, and for a time as a prison ship for detainees. She retained a small party of naval ship-keepers onboard. On 23 May 1978 Maidstone was broken up for scrap at Rosyth.
