The Queen visited HMS Sutherland in West India Dock today to celebrate the 20th anniversary of its commissioning.
She was greeted on board the Type 23 Frigate by Commander Andrew Canale and First Sea Lord Admiral, Sir Phillip Jones.
A luncheon was served in HMS Sutherland's hangar, where the Queen was able to meet people from the the ship's company and families, as well as former commanding officers and affiliates.
Commander Andrew Canale said: "This is a very special day for all who have served on HMS Sutherland and to our affiliates who have supported us over the past 20 years."
"Everyone who's served on Sutherland has much to be proud of and we are honoured to be able to mark this occasion in the presence of Her Majesty The Queen."
During her visit the Queen spent time chatting on the upper deck with the Flight Crew of 815 Naval Air Squadron, based at RNAS Yeovilton.
Lieutenants Oliver Brooksband and James Hume were able to recount their time spent flying the Wildcat helicopter on their recent humanitarian deployment to the Caribbean.
The day's events were concluded with a group photograph with the Queen, and a posy being gifted to Her Majesty.
HMS Sutherland has spent much of the past 12 months as the Fleet Ready Escort and Towed Array Patrol Ship, a task that requires it to be at very high readiness for operational tasking around the UK.
The ship recently completed a six-week operational work-up in preparation for deployment next year.
Shortly afterwards it was tasked as the first Royal Navy escort for the aircraft carrier HMS Queen Elizabeth on sailing from Rosyth for the first time.
