HMS Brazen (F91)

HMS Brazen was a Type 22 frigate of the Royal Navy. She was completed three months ahead of schedule due to the Falklands War.

Royal Navy service
Brazen served on the Armilla Patrol which became a taskforce during the Gulf War. For this she received the battle honour "Kuwait 1991". During the war, her Lynx helicopter attacked fast patrol boats.

Following a patrol in the South Atlantic Brazen ran aground in the Patagonian Canal on 11 September 1994. The ship was refloated four days later and taken to Talcahuano for repairs, which lasted a month. She then returned to the UK under her own power for reinstatement of combat system equipment damaged in the incident.

Brasilian service
She was purchased from the United Kingdom by the Brazilian Navy on 18 November 1994, and renamed Bosísio. The ship was commissioned into the Brazilian Navy on 30 August 1996.

In June 2009, Bosísio participated in the recovery mission for the wreckage of Air France Flight 447.
