The Fifth Sea Lord was formerly one of the Naval Lords and members of the Board of Admiralty that controlled the Royal Navy.[1]  The post's incumbent had responsibility for naval aviation. 
  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.[2] 
During World War I it was one of four additional naval positions added to the Board of Admiralty to manage the Navy.  The only officer to hold the title during the war was Commodore Godfrey Paine. Commodore Paine simultaneously held the title of Director of Naval Aviation. After the Air Force Bill received Royal Assent in November 1917 the Air Council was created on 3 January 1918 which included Paine.[3] 
The post of Fifth Sea Lord then lapsed until 1938 when the Admiralty regained responsibility for naval aviation: the post was reestablished and was the Chief of Naval Air Services, responsible for preparation and management of all of the Royal Navy's aircraft and air personnel.[4] 
From 1957 to 1965 the Fifth Sea Lord's post was held jointly with the Deputy Chief of the Naval Staff. The post was abolished in 1965.[5] 
In the 21st century the Assistant Chief of the Naval Staff (Aviation, Amphibious Capability & Carriers) has a similar role.
