Summary:

- The Burevestnik is a nuclear-powered cruise missile being developed by Russia. It is designed to have virtually unlimited range and maneuverability, allowing it to evade missile defense systems.

- The missile's propulsion system uses a small nuclear reactor to generate power, enabling it to fly for long periods without needing to refuel. This makes it a potentially powerful strategic weapon.

- However, the development of the Burevestnik has faced technical challenges, and there have been concerns about the potential environmental and safety risks of its nuclear reactor. The missile's capabilities and status remain a topic of ongoing speculation and debate.
