From the reckless occupation of the Zaporijjia nuclear power plant to the unveiling of a nuclear-propelled cruise missile Burevestnik, Russia is dragging the nuclear dialectic into erratic, ungoverned terrain. What was once a field bounded by doctrine, deterrence, and responsible stewardship is now being twisted into a theatre of coercion, environmental endangerment, and civilian risk. The shift is not strategic innovation — it is the degradation of nuclear responsibility itself. Very red line.

The public presentation on 26 October 2025 of a nuclear-propelled cruise missile by President Vladimir Putin (9M730 Burevestnik, NATO: SSC-X-9) raises a concern that transcends the traditional boundaries of arms control. It is not merely a question of payload, deterrence posture, or strategic signaling. It is a matter of radiological safety for civilian populations and the collective responsibility of states under international law.

1. Responsibility in Transit: A New Category of Risk

Unlike a conventional warhead—whose nuclear components remain inert until detonation—a nuclear propulsion unit constitutes an active radiological source during the entire flight. Heat production, neutron activation of materials, and potential by-products of fission create a qualitatively different hazard: a flying installation of nuclear risk over civilian infrastructure and ecological systems.

Responsibility no longer concerns only the intent of use, but the externalities of transit itself.

2. Interception Dilemmas and Civilian Exposure

Any state in legitimate self-defense may seek to intercept such a missile. Yet interception—by design—risks fragmenting a core of radioactive material in the atmosphere. In other words, a lawful defensive act can involuntarily contaminate third parties, including neutral airspace or downwind populations.

This represents a profound distortion of responsibility: the defending actor becomes the last causal link in a contamination chain they did not initiate.

3. The Payload Is Irrelevant to the Core Problem

Whether the missile carries a nuclear warhead, a conventional payload, or no destructive payload at all, the risk remains fully intact. A nuclear propulsion unit introduces:

• long-lived radiotoxic materials (plutonium, enriched uranium, activation isotopes) into the battlespace;
• fragmentation hazards under fire or during mechanical failure;
• aerosolization risks capable of contaminating soils, water tables, and food chains for decades.

Thus, focusing on the warhead is a category error. The danger is the reactor itself.

4. Absence of Crew Means Absence of Control

Nuclear submarines and vessels are subject to:

• human supervision,
• emergency shutdown procedures,
• layered containment,
• and maintenance protocols.

A missile, by contrast, offers none of these protections. Its core vulnerability is structural:

• no human oversight,
• no real-time containment capacity,
• no mitigation if struck or malfunctioning.

Responsibility cannot be delegated to guidance software.

5. Collective Responsibility Under International Law

International law already recognizes:

• the no-harm principle (states must not cause transboundary environmental damage),
• the duty of due diligence,
• and the obligation to prevent foreseeable harm.

A nuclear-propelled cruise missile renders compliance structurally impossible. Its mere flight path—regardless of intent—constitutes a foreseeable risk of transboundary radiological contamination.

No state can guarantee:

• permanent mechanical integrity,
• total immunity against interception,
• or fail-safe mission termination above uninhabited zones.

Responsibility therefore shifts from use to existence.

6. A Precedent We Cannot Normalize

Allowing one state to operationalize such systems creates:

• pressure for reciprocity,
• technological emulation,
• and increased probability of accidental contamination.

Normalization would generate a radiological arms race in the atmosphere—without any workable liability mechanism.

7. Required Normative Response

The international community must:

1. Declare a moratorium on flight testing of nuclear-propelled unmanned systems.

2. Open a treaty process to ban airborne nuclear propulsion for weapons entirely.

3. Integrate radiological transit risk into arms-control verification regimes.

4. Empower CTBTO radionuclide networks to publish transparency data on anomalies.

These measures are not optional. They form the minimal architecture of collective safety.

8. Conclusion

Nuclear-propelled cruise missiles constitute an unacceptable externalization of risk:

• They turn the global atmosphere into a vector of radiological uncertainty.
• They shift liability from user to defender, and from combatants to civilians.
• They undermine the premise that nuclear materials must remain confined, controlled, and accountable.

In this domain, silence equals consent.
The international community must assert that the atmosphere is not a battlefield and that the safety of millions cannot hinge on the mechanical integrity of a flying reactor.
