新华社：俄核威慑力量升级的战略意义

Core Viewpoint - Russia is advancing its nuclear deterrent capabilities with the development of the "Zircon" nuclear-powered cruise missile and the "Poseidon" nuclear-powered unmanned underwater vehicle, which may serve as significant bargaining chips in military negotiations with the U.S. as existing arms control treaties approach expiration [1][3][8] Group 1: Weapon Development and Testing - President Putin has publicly highlighted the successful testing of the "Zircon" and "Poseidon," emphasizing their advanced capabilities, including the "Zircon" having a range that exceeds all known missiles and the "Poseidon" being able to dive to depths of 1,000 meters [3][6] - The "Zircon" is reported to have a theoretical unlimited range due to its nuclear propulsion, capable of flying at speeds between 850 to 1,300 kilometers per hour and at ultra-low altitudes [6][8] - The "Poseidon" is described as a compact nuclear-powered underwater vehicle, approximately 20 meters long and weighing around 110 tons, designed to carry a nuclear warhead [6][8] Group 2: Strategic Implications - The introduction of the "Zircon" and "Poseidon" represents an upgrade to Russia's nuclear arsenal, which traditionally consisted of land-based intercontinental missiles, strategic submarines, and bombers, now categorized as the fourth and fifth types of strategic nuclear weapons [8] - These new weapons provide Russia with enhanced leverage in arms control discussions, as existing treaties do not cover such new weaponry, thus increasing Russia's negotiating power [8] - The development and demonstration of these weapons signal Russia's capability to maintain sovereignty despite internal and external challenges [8] Group 3: Perception and Analysis - Analysts suggest that while the technical specifications of the "Zircon" and "Poseidon" are impressive, their practical military value remains uncertain, as they do not represent a revolutionary advancement in military technology [9] - The effectiveness of these new weapons will depend on Russia's satellite navigation and electronic warfare capabilities, which are crucial for achieving operational effectiveness in real combat scenarios [9] - Western analysts view the "Zircon" and "Poseidon" primarily as political tools and psychological deterrents rather than immediate combat assets, indicating that their introduction is unlikely to significantly alter the motivations for first-use of nuclear weapons [9]
