The Russian missiles sought out targets from the Lviv region in western Ukraine near Poland to Kharkiv in northeast Ukraine bordering Russia. The state energy company Ukrenergo reported emergency power outages in six regions. It often shuts down production during attacks as a precaution.

Russia launched a large-scale missile attack on Wednesday, some slamming into energy facilities that caused power losses in several regions of the country, officials said.

President Volodymyr Zelensky of Ukraine said air defenses had shot down at least 30 missiles from a “massive” barrage that had targeted gas and energy facilities.

Ukraine is using a pulse jet engine to power the Trembita missile. Despite being an older, seldom-used design, these engines allow for the easy production of the missile.

Ukrainian officials say Russia has launched a major ballistic and cruise missile attack on regions across Ukraine

Russia launched scores of missiles and drones at Ukraine on Wednesday, targeting gas infrastructure and other energy facilities in western regions in a new barrage against the struggling power system in the depths of winter.

Russia launched dozens of missiles and drones at the Ukrainian energy sector, Kyiv said Wednesday, ramping up a months-long bombing campaign at a precarious moment of the war for Ukraine.The barrage came just one day after Kyiv said it had carried out its largest aerial attack of the war on Russian army factories and energy hubs hundreds of kilometres from the front line.

A massive Russian attack on Ukraine is underway. The Operational Command of the Armed Forces announced that standby pairs of fighter jets have been scrambled, and ground air defence and radar systems have reached the highest state of readiness.
