HMS Duncan has returned home to Portsmouth, after a seven-month deployment which saw her protect British ships in the Strait of Hormuz.
Also on the agenda for the Type 45 destroyer, was working as part of the effort against so-called Islamic State (IS) in Iraq and Syria.
Her homecoming was marked with cheers from hundreds of family members waiting on South Railway Jetty at Her Majesty's Naval Base Portsmouth.
She was away longer than planned.
Her initial mission was to be part of a carrier strike group in operations against IS, but after the seizing of British-flagged tanker the Stena Impero in July, the destroyer was sent to the Gulf.
HMS Duncan made 29 transits of the Strait of Hormuz, escorting nearly 1.3 million tonnes of shipping - which meant more time away from home for the 250-strong ship's company.
The first off the ship was the captain, Commander Tom Trent, who believes their mission was of crucial importance: "The Iranians were absolutely keen, it was clear, to do some more mischief.
"It was absolutely clear, that without HMS Montrose, and HMS Duncan, on task escorting tankers then that would probably have happened.
"I'm always looking for measure of effect, what's the MOE, how are we doing, are we actually achieving something?
"Well yeah, because every day I had two or three tankers with me, who emailed me at the end, captain to captain, saying thanks very much for getting us through safely."
The reunion has been a happy one, and the days ahead will provide opportunities for those involved to tell the story of how they enabled British ships to be safe and free at sea.
