A new memorial to submariners is to be sculpted by well-known artist Paul Day.
The sculpture, which will be installed at the National Memorial Arboretum in Staffordshire, is based on the winning design from a national competition launched last year.
Mr Day is renowned for creations including the Battle of Britain Memorial on London's Embankment and the Meeting Place sculpture at St Pancras station.
The new memorial will be 4m long and 3.5m high, cast in bronze with a quote on the left-hand side from Sir Winston Churchill: "Of all the branches of men in the forces, there is none which shows more devotion and faces grimmer perils than the submariner."
It is set to be opened to the public in 2022 in a ceremony that will be attended by Prince William, Commodore-in-Chief Submarines.
The Submariner Memorial Appeal is currently raising money towards a target total of £375,000 to fund and maintain the project, which will replace the current tribute, a small plaque.
Mr Day said the planned design for the sculpture would set it apart and make it "easily spotted" by visitors to the arboretum.
"Mirroring the winning design, I imagine visitors walking through a somewhat confined space to suggest the constraints upon movement that dictate life on board a submarine," he said.
"The conning tower shape has that advantage of being instantly recognisable, a beacon that could be easily spotted and identified within the plethora of monuments at the arboretum.
"In order to honour the sacrifice of families who bear the brunt of separation and worry, I decorate one side of the conning tower with a low relief depicting spouses, children and parents waiting for their loved ones to return.
"They are present in the hearts and minds of those on board," he added. "Their subtle presence in relief would signify this and the very real part they play in keeping submarines working at sea."
Often known as the 'Silent Service', Royal Navy submarines have been at the forefront of underwater warfare and have been involved in all recent UK military campaigns from Kosovo to Afghanistan and Libya.
