Brazen served on the Armilla Patrol which became a task force during the Gulf War as part of Operation Granby.

[1] On 24 January 1991, Brazen would screen the British Casualty Receiving ship RFA Argus when a pair of Iraqi Mirage F1 aircraft made a run for the vessel, armed with AM39 Exocet anti-ship missiles.

She then returned to the UK under her own power for reinstatement of combat system equipment damaged in the incident at Devonport royal dockyard.

By late 1995, Brazen was back in active service, operating in the Adriatic Sea as part of a Royal Navy task group led by the aircraft carrier HMS Ark Royal for Operation Sharp Guard.

[5] In May 1996, she returned to Devonport for the final time before being officially handed over to the Brazilian Navy in August 1996.
