What is the 9M730 Burevestnik?
The 9M730 Burevestnik (SSC-8 Starfall, as designated by NATO) is a Russian nuclear-powered cruise missile. It’s a fundamentally different weapon system than traditional cruise missiles,relying on a small nuclear reactor for power,allowing for potentially unlimited range and loitering capabilities. Growth began in the early 2010s, and multiple tests have been conducted, often with reported challenges.
Technical Specifications and Operation
Unlike conventional cruise missiles that rely on jet engines and fuel, the Burevestnik utilizes a compact nuclear reactor to generate electricity, powering its propulsion system.This eliminates the need for large fuel tanks, enabling a significantly smaller missile size for a given range. The reactor is reportedly a lead-cooled fast reactor, a technology that presents critically important engineering challenges. The missile is designed to fly at low altitudes, making it difficult to detect by radar.
The operational concept involves the missile flying a complex, unpredictable path, potentially circumnavigating the globe before striking its target. This loitering capability and extended range pose unique challenges for existing missile defense systems. However, the reactor’s operation has been a source of concern, with reports of radiation leaks during testing.
| Specification | Estimated Value | Source |
|---|---|---|
| Length | 8-10 meters (26-33 feet) | Air & Space Forces Magazine |
| Warhead Capacity | 50-100 kilotons (estimated) | Council on Foreign Relations |
| Range | Potentially unlimited | U.S. Department of Defense |
| Propulsion | Nuclear-powered (lead-cooled fast reactor) | Carnegie Endowment for International Peace |
Testing and Controversy
Multiple tests of the Burevestnik have been reported since 2017, often accompanied by concerns about safety and environmental impact. In August 2019, a test launch resulted in a crash in the White Sea, reportedly causing a brief spike in radiation levels.
