(BBC News) – The UK has confirmed it is supplying Ukraine with long-range missiles it requested for its fight against invading Russian forces.
The Storm Shadow cruise missile has a range of over 250km (155 miles), according to the manufacturer.
By contrast, the US-supplied Himars missiles used by Ukraine only have a range of around 80 km (50 miles).
The weapons will give Ukraine the “best chance” of defending itself, UK Defence Secretary Ben Wallace said.
They are fired from aircraft, so the longer range means Ukrainian pilots will be able to stay further from the frontlines.
Once launched, the Storm Shadow drops to low altitude to avoid detection by enemy radar, before latching onto its target with an infra-red seeker.
The announcement was made in the House of Commons by Mr Wallace. The decision follows repeated pleas from Ukraine for more weapons from the West.
Mr Wallace said the missiles would “allow Ukraine to push back Russian forces based on Ukrainian sovereign territory”.
He said the UK took the decision after Russia “continued down a dark path” of targeting civilian infrastructure in Ukraine.
