俄罗斯新型核武器亮相，西方反导系统可能“报废”

Core Viewpoint - Russia has successfully tested two new types of nuclear weapons, the "Zircon" nuclear-powered cruise missile and the "Poseidon" nuclear-powered unmanned underwater vehicle, which have garnered significant attention from Western military and media analysts [1][3]. Group 1: Zircon Missile - The "Zircon" missile is approximately 12 meters long and can carry a nuclear warhead with a yield of 50 kilotons, providing global strike capabilities [1]. - It can fly nearly 30,000 kilometers without interruption due to its nuclear power, operating at a cruising altitude of 25 to 100 meters, which allows it to evade enemy air defense systems [3]. - The missile's potential flight path includes low-altitude travel over the Arctic, crossing the Atlantic, and ultimately reaching the North American west coast, posing a strategic threat to NATO [3]. Group 2: Poseidon Underwater Vehicle - The "Poseidon" is about 20 meters long and weighs around 100 tons, powered by a liquid metal-cooled reactor, capable of underwater travel at depths of up to 1,000 meters for over 10,000 kilometers [4]. - It can carry a nuclear warhead with a yield of up to 1 megaton, sufficient to destroy military ports and warships, and disrupt commercial shipping for an extended period [6]. - The Poseidon operates outside the current arms control regulations, making it difficult for the West to monitor, and poses a challenge to existing land-based and space-based missile defense systems [6]. - Analysts suggest that large-scale deployment of the Poseidon could enhance Russia's second-strike capabilities and compel the West to invest heavily in underwater defense systems [6].
