Here Is How Russia’s Skyfall Nuclear-Powered Cruise Missile Actually Works

Researchers conclude the nuclear-powered cruise missile almost certainly uses a direct-cycle engine that spews radioactive material throughout its flight. The post Here Is How Russia’s Skyfall Nuclear-Powered Cruise Missile Actually Works appeared first on The War Zone .

Why this matters
Why now

Ongoing geopolitical tensions and Russia's declared intent to develop advanced strategic weapons bring renewed focus to its nuclear-powered cruise missile programs.

Why it’s important

This development indicates a renewed nuclear arms race and the proliferation of potentially destabilizing weapons systems with global reach and unprecedented endurance.

What changes

The understanding of Russia's 'Skyfall' missile now includes credible details about its highly hazardous propulsion mechanism, confirming it as a significant threat that disperses radioactive material.

Winners
  • · Russian strategic forces
  • · Nuclear weapon developers
Losers
  • · Global non-proliferation efforts
  • · Environmental safety
  • · Nuclear arms control treaties
Second-order effects
Direct

The confirmation of a direct-cycle nuclear engine in 'Skyfall' reveals a weapon with virtually unlimited range but also inherent environmental risks during its operation and potential failure.

Second

This could accelerate other nations' research into similar strategic weapons or counter-proliferation technologies, fueling a new phase of the arms race.

Third

The environmental hazard posed by such a missile could lead to international diplomatic incidents or heightened concerns over radioactive contamination in the event of deployment or testing.
