The British Royal Navy has received approval from Buckingham Palace to name Portsmouth Naval Base’s upgrade the Princess Royal Jetty.

The Middle Slip Jetty is undergoing an upgrade to accommodate the 65,000t HMS Queen Elizabeth and her sister ship HMS Prince of Wales.

Portsmouth Naval Base commander Jeremy Rigby said: "We are delighted that Her Majesty the Queen has agreed to the Royal Navy’s request to rename the jetty.

"The Princess Royal, as commodore-in-chief for Portsmouth, is a frequent visitor to the base and takes a keen interest in all of our activities here."

Work started in July 2015 to revamp facilities at Portsmouth Naval Base, as part of a £100m investment.

With £34m of investment, the 18-month works will see improvements to the 90 years old Middle Slip Jetty.

Last December, dredging works started at the base to develop docks for the two Queen Elizabeth Class carriers.

Currently being fitted out at Rosyth dockyard in Scotland, HMS Queen Elizabeth is due to arrive in Portsmouth in early 2017.

"With £34m of investment, the 18-month works will see improvements to the 90 years old Middle Slip Jetty."

Featuring a flight deck spanning around 4.5 acres, the HMS Queen Elizabeth can launch, land and maintain aircraft 24-hours-a-day for war efforts and humanitarian aid and disaster relief operations.

Construction work at the jetty is being undertaken by VolkerStevin, which has built the new ammunition facility in Portsmouth Harbour for the six Type 45 destroyers based in the city.

The base’s head of infrastructure captain Iain Greenlees previously said: "This is a huge project, and a very exciting one, refurbishing and rebuilding jetties, bringing in new power facilities, installing navigation beacons, dredging millions of tonnes of mud.

"This programme confirms the future of Portsmouth Naval Base for the next 50 to 80 years. It will be the only port which can fully support HMS Queen Elizabeth and Prince of Wales and meet all their needs."
