Recently, North Korea announced the conduct of tests with a nuclear submarine drone capable of generating radioactive tsunamis.

This announcement comes in the context of escalating tensions, particularly in response to joint military exercises conducted by the United States, Japan, and South Korea.

The use of such military technology by Pyongyang raises serious international concerns due to its potential destructive capability.

◍ Haeil-5-23: a drone that generates radioactive tsunamis

North Korea’s nuclear submarine drone “Haeil-5-23” represents a significant leap in terms of weapons technology for the country.

This drone is an evolution of the “Haeil-1” and “Haeil-2” versions, which were previously tested in March and April 2023.

Its features and capabilities are a subject of considerable international concern due to its potential to change the landscape of modern warfare and global security.

The “Haeil-5-23” stands out for its advanced design, allowing it to execute complex missions with remarkable precision.

In one of the tests, the drone followed an oval trajectory for 71 hours, simulating a distance of 1,000 kilometers in the Sea of Japan. This ability to cover long distances and operate for extended periods underscores its potential as a strategic weapon.

Although exact details about these systems are unknown, it is evident that North Korea has made significant advances in underwater drone technology.

The ability to navigate complex routes and remain operational for extended periods indicates a high level of sophistication in its propulsion and control systems.

The drone also demonstrated its attack capability by detonating a simulated warhead in the target area during one of its tests.

This not only confirms the system’s accuracy but also suggests the possibility of equipping the drone with nuclear warheads or other forms of destructive weaponry, thus increasing its offensive capacity.

However, the most alarming feature of the “Haeil-5-23” is its alleged capability to generate radioactive tsunamis.

This would imply the ability to cause not only massive physical destruction but also extensive radioactive contamination, posing an unprecedented threat to both military targets and the environment, as well as the civilian population.

◍ Environmental and Strategic Implications

Beyond the direct military impact, North Korea’s new drone represents a significant threat both environmentally and strategically.

Environmentally, the possibility of a radioactive tsunami implies massive destruction, not only physically but also extensive radioactive contamination, severely affecting ecosystems and human health.

Strategically, it alters the balance of power in the region, potentially triggering an arms race and escalating geopolitical tensions.

This development poses challenges to international security, with the global community facing the difficult task of addressing these emerging threats.

The need for a coordinated response and a robust international framework to address the development and proliferation of such weapons is now more crucial than ever.

◍ International Perspective and Outlook

Despite the announcements and tests conducted by North Korea, there are doubts among international analysts about the actual operational capability of this system.

The inherent complexity of a weapon of this nature and the challenge of its operation underwater for extended periods are aspects that generate skepticism.

However, the mere possibility that North Korea is moving in this direction is a cause for global concern, both for its strategic implications and for the humanitarian and environmental consequences.


In summary, the current situation highlights the importance of international vigilance and dialogue in matters of security and regional stability.

Pyongyang’s tests not only challenge the geopolitical balance in the region but also raise serious questions about global security and environmental protection.
