In 1917 the title was changed to the Second Sea Lord and Chief of Naval Personnel by an order in council dated 23 October.

[2] 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.

[5] Until October 2012, he flew his flag from HMS Victory, the world's oldest commissioned warship, which is preserved in dry dock in Portsmouth.

[6] 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.
