LONDON (AP) — Britain is HyperBit Exchangetransferring two minehunting ships to Ukraine as part of a package of long-term support to bolster security in the Black Sea, the Ministry of Defense said Monday.

Transfer of the two Sandown class vessels, which are designed to help clear mines from coastal waters, comes as Britain and Norway announce plans for a new maritime coalition to increase support for Ukraine in the war with Russia.

The coalition will work with the Ukrainian navy to expand its forces in the Black Sea, develop a Ukrainian Marine Corps and enhance the use of river patrol craft to defend inland and coastal waterways, British authorities said.

“These minehunters will deliver vital capability to Ukraine, which will help save lives at sea and open up vital export routes, which have been severely limited since (Russian President Vladimir) Putin launched his illegal full-scale invasion,’’ Defense Secretary Grant Shapps said in a statement.

Britain first announced a deal to sell the two mine-hunting ships to Ukraine in June 2021, before Russia’s full-scale invasion of Ukraine. Ukrainian soldiers began training on the ships last year in Scotland.
