The Storm Shadow has a range of approximately 560 km ( 350 mi) and Kiev could theoretically hit Moscow with the British long-range missiles. David Cameron gave Kiev the greenlight to do it. Moscow would then retaliate by targeting Kiev directly.
The United Kingdom has authorized Ukraine to use Storm Shadow missiles supplied to it to attack Russian facilities, Kiev has already used such weapons, a Ukrainian official said.
"We already have a precedent. For example, the United Kingdom has previously allowed Ukraine to use the long-range Storm Shadows missiles it provided," Yury Sak, adviser to Ukrainian Strategic Industries minister, told Bloomberg. He added that the Ukrainian armed forces "have already used them."
German Chancellor Olaf Scholz has repeatedly said that he rules out supplying Kiev with long-range Taurus cruise missiles because Berlin would not be able to maintain control over targeting without sending German troops to Ukraine, which he said is a line he does not want to cross.
There is no complete unanimity among Kiev's Western allies, which have multiplied arms deliveries to Ukraine since the start of the Russian special military operation, on restrictions on its use
