She was the first ship to leave the United Kingdom ahead of the task force for the South Atlantic during the 1982 Falklands War.

Typhoon saw service in the Falklands War from leaving the UK on 4 April 1982 until 20 July 1982 under Captain J N Morris with an all-civilian crew from Portland Naval Base.

Under the command of Captain Bruce Stephens she returned to Portland with her new civilian crew.

She was the first ship – albeit a civilian vessel – to leave the UK ahead of the task force, and a member of the crew, the tug's bosun, placed the Welsh flag on board RFA Sir Galahad just before Typhoon towed her out to sea to be scuttled by a submarine.
