Second Sea Lord and Deputy Chief of Naval Staff

The Second Sea Lord and Deputy Chief of Naval Staff (formerly Second Sea Lord) is deputy to the First Sea Lord and the second highest-ranking officer to currently serve in the Royal Navy and is responsible for personnel and naval shore establishments. Originally titled Second Naval Lord in 1830, the post was restyled Second Sea Lord in 1904. They are based at Navy Command, Headquarters.

History
In 1805, for the first time, specific functions were assigned to each of the 'Naval' Lords, who were described as 'Professional' Lords, leaving to the 'Civil' Lords the routine business of signing documents. The Second Naval Lord was the second most senior Naval Lord on the Board of Admiralty and as Chief of Naval Personnel was responsible for handling all personnel matters for the Royal Navy. In 1917 the title was changed to the Second Sea Lord and Chief of Naval Personnel by an order in council dated 23 October.

The posts of Second Sea Lord and Commander-in-Chief, Naval Home Command (CINCNAVHOME) were amalgamated in 1994 in the reductions of the British Armed Forces following the end of the Cold War. The original post of Commander-in-Chief, Naval Home Command had been created on 1 July 1969, as a result of the merger of the posts of Commander-in-Chief, Portsmouth and Commander-in-Chief, Plymouth.

2SL is based in Portsmouth in a combined headquarters with the Fleet Commander on Whale Island. Until October 2012, he flew his flag from HMS Victory, the world's oldest commissioned warship, which is preserved in dry dock in Portsmouth. The right to use HMS Victory as a flagship came from his position as CINCNAVHOME, who in turn acquired it from the Commander-in-Chief, Portsmouth. Since October 2012, distinct Commander-in-Chief posts have been discontinued and full command responsibility is vested in the First Sea Lord, who now flies his flag from Victory; this change formed part of the Levene reforms which were implemented at that time.

In 2016 the post was retitled Second Sea Lord & Deputy Chief of Naval Staff and defined as "responsible for the delivery of the Naval Service’s current and future personnel, equipment and infrastructure".
