Ukraine’s shock drone strike on Russia’s strategic bomber fleet this week has generals and analysts taking a new look at threats to high-value United States aircraft at bases in the homeland and abroad – and the situation is worrisome.

Russia launched an intense missile and drone barrage at the Ukrainian capital Kyiv in the early hours of Friday, killing at least six people, Ukrainian officials said, as powerful explosions reverberated across the country.

Russia struck Ukraine with a thunderous aerial bombardment overnight, further dampening hopes that the warring sides could reach a peace deal anytime soon days after Kyiv embarrassed the Kremlin with a surprising drone attack on military airfields deep inside Russia.
