The British government said it would provide Ukraine with 650 lightweight multi-role missiles worth $213.13 million, to help protect the country from Russian drones and bombing.
Last week Russia unleashed its largest air attack on Ukraine since the full-scale war began early in 2022. Ukraine has made repeated requests for more air defence support to defend itself from missile and drone attacks.
The new supply of missiles was announced as British defence minister John Healey attended the Ukraine Defence Contact Group, an ad-hoc coalition of some 50 nations, at a US air base in Germany.
The Ministry of Defence said, in keeping with the new government's commitment to speed deliveries of aid to Ukraine, the first batch of missiles announced on Friday were expected to arrive by the end of the year.
"This new commitment will give an important boost to Ukraine's air defences," Healey said in a statement.
The Ministry of Defence said the missiles made by Thales have a range of more than six kilometres (3.73 miles) and can be fired from a variety of platforms on land, sea, and air.
Last Monday, Russia fired more than 200 missiles and drones at Ukraine, killing seven people and striking energy facilities nationwide in what Kyiv called the war's "most massive" attack.
