Flying at heights of several kilometers and close to the speed of a commercial aircraft, Moscow’s new long-range jet-powered drones are causing havoc among Kyiv’s overt-stretched air defenses. In recent weeks Moscow has been launching waves of the attack drones at the Ukrainian capital, paralyzing the city with near constant air alerts.JOIN US ON TELEGRAMFollow our coverage of the war on the @Kyivpost_official. Ukrainian President Volodymyr Zelensky on Sunday slammed the “horror that’s been happening in the sky these past few days” in response to Russian leader Vladimir Putin’s new , and vowed a response. The new drones pose a challenge to Ukraine’s previously effective and low-cost anti-drone defense shield, that was hastily developed following Russia’s 2022 invasion. Ukraine has quickly become a world leader in drone defense and has struck deals with several Western and Middle Eastern countries to share its technology. However, its network of drone interceptors – which had been shooting down the vast majority of Russia’s more conventional drones, powered by internal combustion engines and propellers – faces a more challenging task against the new jet-powered devices. Experts say they are fitted with Chinese-made aircraft-style mini jet engines and can fly five kilometers in the air at speeds of 400-600 kilometers (250-370 miles) per hour – up to three times the speed of previous versions based on Iran’s Shahed drones.
