US Unveils “Manta Ray” Drone: A Stealth Underwater Vehicle Capable of Travelling 6,200 Miles While Remaining Hidden
The United States has introduced one of its most advanced underwater technologies to date — an autonomous “Manta Ray” drone capable of travelling an astonishing 6,200 miles beneath the ocean’s surface while remaining virtually undetected. The development marks a major leap forward in naval innovation, signalling a new era of silent, long-range underwater operations.
A Breakthrough in Undersea Autonomy
Developed under the direction of the U.S. Defense Advanced Research Projects Agency (DARPA), the Manta Ray drone is designed to operate for months at a time without surfacing. Shaped like the marine creature it is named after, the drone glides through deep waters with minimal energy use, allowing it to cross entire oceans on a single mission.
Engineers behind the project say its streamlined, wing-like structure reduces drag and helps it blend seamlessly into the surrounding environment, making detection by hostile forces extremely difficult.
6,200 Miles of Covert Travel
What sets the Manta Ray apart from previous underwater drones is its extraordinary range. Capable of travelling up to 6,200 miles (10,000 km) without resupply, the drone can complete strategic missions across continents, positioning itself for surveillance, reconnaissance, or equipment deployment far beyond U.S. territorial waters.
This endurance is made possible through a modular payload system and highly efficient power management technology, enabling the vehicle to drift, glide, or power forward depending on conditions and mission requirements.
Stealth Features Designed for a New Era of Conflict
As global tensions shift increasingly toward maritime theatres — particularly in the Pacific and Arctic regions — underwater stealth has become a top priority. The Manta Ray drone is engineered to operate silently, avoiding sonar detection while navigating deep-sea corridors.
Its low-power mode allows it to “hibernate” on the ocean floor, acting as a dormant strategic asset that can awaken when activated remotely. This ability raises the possibility of underwater drones being pre-positioned for months or years — a capability militaries have long sought but never fully achieved.
Revolutionising Underwater Logistics and Surveillance
Beyond reconnaissance, the Manta Ray’s modular design opens the door to additional uses:
• Subsea supply missions, delivering equipment or sensors to hard-to-reach installations
• Environmental monitoring, using advanced sensors to track seismic, chemical, or biological activity
• Mine detection and clearance, providing safer operations in conflict zones
• Communications relaying, enabling long-distance data transfer between naval assets
The U.S. military has suggested that the drone may eventually act as an underwater “mothership,” deploying smaller unmanned vehicles once it reaches its destination.
A Strategic Advantage in the Underwater Race
The debut of the Manta Ray comes amid heightened competition over undersea dominance, with nations such as China and Russia investing heavily in underwater robotics and anti-submarine technology. The U.S. sees unmanned systems as a way to extend its reach while reducing risks to human personnel.
If fully deployed, the Manta Ray could become one of the most significant additions to America’s maritime toolkit in decades — a silent sentinel capable of crossing oceans, remaining hidden, and reshaping how nations prepare for the conflicts of the future.
As oceans become the next frontier in global defence, technologies like the Manta Ray signal that underwater warfare is entering an entirely new chapter.
