This week we zero in on the military tech sector in Ukraine with our correspondent Gulliver Cragg and Kateryna Bondar, a fellow at the Center for Strategic and International Studies in Washington. Since the start of Russia's full-scale invasion in 2022, an improvised industry of defence tech startups has surged, and technology – particularly drones – has helped Kyiv to hold the line against Moscow. But the country currently lacks the funding to scale production. Meanwhile the Kremlin is catching up, rapidly growing its domestic production of Shahed drones.
