Rear Admiral Submarines

Commodore Submarine Service is a post in the Royal Navy which involves command of the Royal Navy Submarine Service. It evolved from the post of Inspecting Captain of Submarines in 1901 and would later evolve to become the post of Flag Officer Submarines in 1944.

History

In 1904 the Admiralty created the post of ''Inspecting Captain of Submarines'' which lasted until August 1912 when Captain Roger J. B. Keyes was appointed Commodore, Submarine Service. He held that position until February 1919 when the post holder was renamed Chief of the Submarine Service. It was for many years located at HMS ''Dolphin'' in Hampshire.

On 30 August 1939 Rear Admiral Submarines, Rear Admiral Bertram Watson, moved his headquarters from Gosport to Aberdour, Scotland, though the administrative staff remained at Gosport. The RN started the Second World War with 60 submarines. On 31 August 1939 the Second Submarine Flotilla at Dundee ( and ten submarines) and the Sixth Submarine Flotilla at Blyth ( and six submarines) were part of the Home Fleet. The submarines and , part of the Seventh Submarine Flotilla, were at Freetown under the orders of the Commander-in-Chief, South Atlantic. Ten submarines were in the Mediterranean along with the depot ship (First Submarine Flotilla); and the submarine depot ship and the Fourth Submarine Flotilla were under the Commander-in-Chief, China, split between Singapore and Hong Kong. Roskill writes that the effective naval strength of the British Empire on the outbreak of war included 38 submarines.

During the war the major operating arenas were the Norwegian waters; the Mediterranean where the Tenth Submarine Flotilla fought a successful battle against the Axis replenishment route to North Africa; and the Far East where Royal Navy submarines disrupted Japanese shipping operating in the Malacca Straits.

In January 1940, Vice-Admiral Max Horton was made Rear Admiral Submarines. Horton's biographer, Rear Admiral William S. Chalmers, cites the opinion that a new regulation, which required the post holder to be an officer who had served aboard submarines in the Great War, was forced through for the sole purpose of ensuring that Horton was on a very short list of qualifiers for this post, almost ensuring his rapid transfer to Aberdour, so great was the desire of some within the Admiralty to have Horton revitalize the submarine arm.

From 1953 the Flag Officer Submarines was dual-hatted as NATO Commander Submarine Force Eastern Atlantic (COMSUBEASTLANT) under Commander Submarine Allied Command Atlantic (COMSUBACLANT), a major command of Supreme Allied Commander Atlantic. Flag Officer Submarines moved from ''Dolphin'' to the Northwood Headquarters in 1978. From 1993 the post of Flag Officer Submarines was dual-hatted with the post of Commander Operations.

In 2015, Rear Admiral John Weale was appointed Rear Admiral Submarines/Assistant Chief of Naval Staff Submarines, while Rear Admiral Robert Tarrant is Commander Operations (Royal Navy), two distinct posts from 2015. In 2016, a new entity, the Submarine Flotilla, was technically established, but its commander's post was to be held by Commander Faslane Flotilla. A single submarine base was to be achieved by 2020 when HMS ''Talent'' and HMS ''Triumph'' moved their homeports to the Clyde in 2019 and 2020 respectively.

On 1 April 2020, the post of Commander Submarine Flotilla was announced at HMNB Clyde,See it here

As of December 2020, official Royal Navy Freedom of Information responses said that "the combined 2* Rear Admiral post of Assistant Chief of the Naval Staff (ACNS) (Submarines)(SM), Flag Officer Scotland and Northern Ireland (FOSNI) and Rear Admiral Submarines has been disestablished. The ACNS (SM) role and Rear Admiral Submarines roles have been de-enriched to Commodore and retitled Deputy Director Submarines and Commodore Submarine Service. The role of Flag Officer Scotland and Northern Ireland role has been retitled as Senior Naval Officer Scotland and Northern Ireland (SNOSNI) and is currently held by 1* Deputy Director Submarines."
