In 1945, Armada joined the British Pacific Fleet but did not see action during the Second World War.

The following year, as part of the 19th Destroyer Flotilla, Armada deployed to the Far East, performing a variety of duties while based there, and the following year, Armada, with the rest of the 19th Flotilla, returned home to the UK, visiting a variety of ports on the way, mainly on 'fly-the-flag' visits.

Armada remained in the sunny climes of the Mediterranean until returning home to the UK with the rest of the 3rd Destroyer Flotilla.

In June, 1958 Armada provided escort for the Royal Yacht whilst the Queen visited North East England.

Following this she steamed anti clockwise around Scotland and proceeded into the Mediterranean and then onto to the conflict in Cyprus patrolling up and down the west coast to prevent arms smuggling.
