The Flag Officer, Second Flotilla was a senior British Royal Navy appointment from 1971 to 1992.

After the creation of the single Commander-in-Chief Fleet post in 1971, its subordinate commands were reorganised.

Three major sub-commands were created; the First Flotilla, Second Flotilla and Carriers and Amphibious Ships each commanded by a rear admiral.

Rear Admiral Brigstocke, the incumbent Flag Officer Second Flotilla, commanded the HMS Ark Royal (R07) task group off Libya during the Gulf War.

[2] In April 1992, the system was changed when the Third Flotilla was abolished and the remaining two flotilla commanders became Flag Officer, Surface Flotilla - responsible for operational readiness and training; and Second Flotilla became Flag Officer, UK Task Group, who would command any deployed task group.
