The UK Royal Navy's Duke-class Type 23 frigate HMS Monmouth has returned to operational service after successfully completing its 20-month refit and upgrade programme.
The frigate recently completed fleet date inspection in Naval Base Devonport, performing extensive sea trials to test its upgraded weapon systems and sensors.
HMS Monmouth captain commander Philip Tilden said: "Today has been a wonderful opportunity to mark this significant occasion and invite all those who have supported the ship throughout her life, as well as families and friends.
"Now we look to the future, as she is now ready to sail into the 21st century in service of the nation.''
The refit programme was aimed at providing upgrades and improvements to significantly enhance the vessel's sustainability and fighting capability.
As part of the programme, the vessel received new weapon systems and sensors, including new 3D air surveillance radar, the Sea Wolf defence missile system, and a new command and control combat system.
Upgrade work included vertical launch a Seawolf midlife update, galley updates, installation of a chloropac system, and modifications to high-pressure air systems.
In addition, the warship received significant amounts of structural work to its superstructure, which included approximately 17t of new steel, covering an area of 220m² and more than 1.1km total.
HMS Monmouth is now ready to operate in UK and European waters under the full command of the fleet commander, the Royal Navy stated.
