The Ukrainian military says its new weapon system, which launches antiaircraft missiles from a remote-controlled speedboat, has brought down two Russian jet fighters.

At least 10 Ukrainian drones were shot down on their approach to Moscow overnight into Sunday morning, according to the city's mayor.

Russia bombarded Ukraine’s second-largest city with massive strikes in the early hours of Saturday, its mayor said, one night after Moscow carried out one of the war’s largest aerial assaults on Ukraine.

Former Rep. Chris Stewart, a former fighter pilot, says the U.S. isn’t prepared for this change in modern warfare.

Rachel Maddow explains how Ukraine's "Spiderweb" drone operation, which destroyed several Russian military planes, exposed a huge global nuclear vulnerability.

Russian President Vladimir Putin told President Donald Trump in a phone call Wednesday that he was obligated to respond to Ukraine’s weekend drone attack, Trump said, setting up a potential escalation in the conflict just as the US president hopes to broker an end to the war.
