Bacchante was deployed to the Persian Gulf in 1981 conducting the second ever Armilla patrol taking over from the Minerva visiting the Somali capital of Mogadishu and the Oman capital of Muscat (often drifting in the Indian Ocean to conserve fuel). In 1982, Bacchante became the Gibraltar Guardship and joined the Birmingham group deploying to the South Atlantic to undertake duties during the Falklands War. Shortly after the war was ended the crew was sent ashore to aid the local populace in the disaster recovery operations, providing navigational landmarks for ships located in Stanley Sound and attempting to refloat the high commissioner's barge (but failing); also proving well deserved respite for royal marines and navy divers (hot food and accommodation). Whilst trying to erect a navigational radar reflector the team sent ashore, they wandered through a mine field (no injuries received).
In 1982 Bacchante was decommissioned from the Royal Navy and subsequently sold to the Royal New Zealand Navy (RNZN). She was renamed Wellington. She decommissioned from the RNZN in 2000.
On decommissioning she was bought from the New Zealand Government for one dollar by the "Sink F69 Trust". On 13 November 2005, after cleaning and the removal of all environmentally unfriendly materials, she was sunk as an artificial reef and dive attraction. She now lies in approximately 25 metres of water about 800 metres offshore from Island Bay, a southern suburb of Wellington, the capital city of New Zealand.
