UK government starts contest to have deep-strike prototypes delivered within 12 months; heat-starved Kyiv under Russian attack again. What we know on day 1,419 Britain is to develop a new deep-strike ballistic missile for Ukraine, the government has announced. Under the project, named Nightfall, the British government said on Sunday that it had launched a competition to rapidly develop ground-launched ballistic missiles that could carry a 200kg (440lb) warhead to a range of more than 500km (310 miles). “Nightfall missiles will be capable of being launched from a range of vehicles,” said the UK defence ministry (MoD), “firing multiple missiles in quick succession and withdrawing within minutes – allowing Ukrainian forces to hit key military targets before Russian forces can respond.” Three industry teams would each get £9m to design, develop and deliver their first three Nightfall missiles within 12 months for test firings, said the MoD. Ukraine’s current ballistic missiles include Atacms, for which it relies on the US, and the self-developed Sapsan. Russia was again attacking Kyiv early on Monday, the Ukrainian military said, sparking a fire in at least one district. Ukrainian air defences were at work against incoming targets, said Timur Tkachenko, head of Kyiv’s military administration. The renewed attack came as more than 1,000 apartment buildings in the Ukrainian capital remained without heating because of a Russian bombardment on Friday. Volodymyr Zelenskyy, Ukraine’s president, said that despite repairs the situation was “still extremely difficult”, particularly in border regions. At the Vatican, Pope Leo offered prayers for the people of Ukraine, saying the “particularly serious” strikes on energy infrastructure were “hitting the civilian population hard, just as the cold weather is getting worse … I pray for those who are suffering and renew my appeal for an end to violence and for efforts to achieve peace to be intensified.” Ukraine’s forces hit three drilling platforms operated by Russian oil company Lukoil in the waters of the Caspian Sea, the Ukrainian military general staff announced on Sunday. The strikes on Russian energy sites aim to deprive Moscow of oil export revenue used to fund the war. Moscow meanwhile said a Ukrainian drone strike killed one person and wounded three others in the Russian city of Voronezh. Continue reading...
