The UK Royal Navy’s two Hunt-class mine countermeasure vessels, HMS Atherstone and HMS Quorn, are set to undergo their mid-life overhaul at the Portsmouth ship hall, UK.

BAE Systems has been appointed to carry out the overhaul work on the navy’s minehunters.

The overhaul work will see the minehunters being installed with new machinery, sensors, systems, galleys, propellers, overhauled mess decks and improved chilled water plants.

"We will continue to ensure these vital ships are available for the Royal Navy to use for years to come."

In addition, the vessels will be fitted with new Caterpillar engines, which will replace the previously used Deltics.

BAE projects and operational performance director Barry Woolley said: “It is an exciting time to be involved in the upgrade of the Royal Navy’s minehunters and great to see the Royal Navy making best use of its undercover facilities for the Hunt class.

“These ships are crucial to the mine countermeasures capability of the Royal Navy.

“We will continue to ensure these vital ships are available for the Royal Navy to use for years to come.”

Work on the two minehunters closely follows the successful completion of the refurbishment of HMS Brocklesby.

The shed at Portsmouth was built to accommodate the construction of large sections of the navy’s Type 45 destroyers, and was extended for larger sections of Queen Elizabeth-class aircraft carriers.

The 196ft-long Hunt-class minehunters have been designed to be deployed for minesweeping and minehunting, as well as conduct patrol missions.

HMS Atherstone has been a part of the Royal Navy operation in the Gulf to maintain the region’s maritime security and safeguard the vessels.

HMS Quorn has been deployed into Nato’s taskforce of seven ships in the Standing Nato Mine Countermeasures Group One (SNMCMG1) to conduct training exercises and clear historic minefields in the Baltic Sea.
