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 defense support to defend itself from missile and drone attacks.

The new supply of missiles was announced as British Defense Minister John Healey attended the Ukraine Defense Contact Group, an ad-hoc coalition of some 50 nations, at a U.S. air base in Germany.

The British Ministry of Defense said that, in line with the new government’s commitment to expediting 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 defenses,” Healey said in a statement.

The Ministry of Defense said the missiles made by the Belfast-based defense contractor Thales have a range of more than 6 kilometers (3.73 miles) and can be fired from a variety of platforms on land, sea, and air.

On 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.
