A Drone That Flies Like a Plane and Dives Like a Submarine [Video]

How Submersible Flying Drones Are Opening a New Frontier in Robotics

For most of the modern drone era, innovation has focused on the sky. Engineers have spent the past decade refining propellers, sensors, navigation algorithms, and batteries to push aerial drones further and faster. The goal has largely been the same: extend the reach of machines that can fly.

But a new class of robotics is quietly changing that assumption. In recent demonstrations circulating online, engineers have revealed a remarkable machine — a submersible flying drone capable of seamlessly transitioning between air and water. It can dive beneath the ocean’s surface like a submarine, maneuver underwater, and then burst back into the sky to continue flight.

The moment it breaks the surface of the water and launches back into the air feels almost like science fiction. Yet it represents something deeper than an impressive engineering trick. It signals the emergence of a new generation of machines that can operate across environments once thought to be separate.

For decades, engineers treated air and water as fundamentally different operational domains. Aircraft were designed for the sky, submarines for the ocean, and robots were usually confined to one or the other. But amphibious aerial drones blur that boundary entirely. They introduce a new category of robotic vehicle capable of navigating both worlds.

The sky and the ocean are no longer separate territories. They are becoming a single continuous operational space.

Engineering Across Two Worlds

Designing a drone that works both in air and underwater is far more complicated than simply waterproofing an aircraft. Air and water behave very differently from a physics standpoint. Water is roughly eight hundred times denser than air, which dramatically changes how propulsion, drag, and control behave.

A propeller that performs well in air encounters far greater resistance underwater. Structural components must withstand pressure while remaining lightweight enough for flight. Sensors must function in two drastically different environments. Electronics must be sealed while still dissipating heat.

Submersible drones solve these problems through a combination of advanced materials, sealed electronics compartments, hybrid propulsion systems, and sophisticated flight control algorithms. When flying, the drone behaves much like a conventional aerial platform. When it enters the water, the same propulsion system operates more like a thruster, allowing the vehicle to maneuver underwater.

Perhaps the most difficult part of the engineering challenge is the moment of transition. The drone must plunge into the water without damaging itself, stabilize underwater, and then later generate enough thrust to break through the surface and return to flight. That transition requires careful balancing of buoyancy, thrust, and structural resilience.

Until recently, these kinds of machines were largely experimental prototypes in research laboratories. Advances in robotics, battery technology, and materials science are now bringing them closer to real-world deployment.

A New Tool for Ocean Infrastructure

One of the most compelling applications for submersible flying drones lies beneath the ocean’s surface, where vast networks of infrastructure quietly support the global economy.

Undersea fiber optic cables carry the majority of the world’s internet traffic. Offshore wind farms generate growing amounts of renewable energy. Pipelines transport fuel across continents. Ports and shipping terminals depend on submerged structures that must be inspected regularly for safety.

Maintaining this infrastructure is both expensive and logistically complex. Inspections often require specialized dive teams, remotely operated vehicles tethered to ships, or large support vessels that must travel long distances offshore. Each inspection can involve significant operational costs and safety risks.

Submersible drones offer an entirely different approach.

Imagine a small autonomous drone launched from a coastal facility or research vessel. It flies several kilometers across open water to reach an offshore structure. Upon arrival, it lands on the ocean surface and submerges beneath the waves. Equipped with cameras, sonar systems, and artificial intelligence–based inspection tools, the drone scans structural components for corrosion, cracks, marine growth, or other forms of damage.

Once the inspection is complete, the drone resurfaces and lifts back into the air, returning to its launch point with collected data.

What once required large crews and expensive ships could potentially be handled by a single autonomous robotic platform. More importantly, the lower cost of such systems would allow infrastructure operators to conduct inspections more frequently, identifying problems long before they become catastrophic failures.

As offshore energy and underwater communications networks continue expanding, the demand for efficient inspection technologies will only grow.

Security Beneath the Surface

Beyond industrial inspection, submersible flying drones also introduce powerful new capabilities for maritime security.

Coastal environments are among the most complex operational zones in the world. Threats can emerge from both air and underwater, and protecting ports, shipping lanes, and underwater infrastructure requires constant monitoring across multiple domains.

Traditional security systems often specialize in one environment. Aircraft patrol the sky while submarines or underwater vehicles monitor the sea. Coordinating these systems requires extensive resources and personnel.

Amphibious drones change that dynamic by combining aerial surveillance and underwater investigation within a single machine.

A drone could patrol a harbor from the air, scanning wide areas quickly using visual and radar sensors. If something suspicious is detected near the water, the drone could descend, land, and submerge to investigate underwater activity directly. It could inspect ship hulls for hidden devices, monitor underwater infrastructure for tampering, or track autonomous underwater vehicles moving through restricted areas.

Because drones are relatively inexpensive compared to manned patrol vessels or aircraft, fleets of them could operate continuously. This creates a new form of persistent maritime awareness, allowing authorities to monitor sensitive areas with far greater coverage.

Recent geopolitical developments have underscored the vulnerability of underwater infrastructure, from pipelines to communications cables. Technologies that can observe both above and below the ocean’s surface will become increasingly valuable for protecting these critical systems.

The Shift in Global Drone Supply Chains

The rapid advancement of drone technology is also occurring alongside major changes in global supply chains.

For many years, the commercial drone industry depended heavily on manufacturing in China. However, growing security concerns and geopolitical tensions have led many governments and organizations to reconsider that reliance.

In numerous sectors, drones manufactured in China can no longer be imported or used due to regulatory restrictions and national security considerations. This shift has created a significant gap in the market for trusted alternatives.

Taiwan is uniquely positioned to fill that gap.

With its globally dominant semiconductor industry and highly advanced electronics manufacturing ecosystem, Taiwan has long been a cornerstone of modern technology supply chains. The same capabilities that power the world’s computing and communications devices can also support the development of next-generation robotics platforms.

Taiwanese companies are increasingly moving into the drone sector, combining expertise in sensors, processors, and precision hardware to build sophisticated unmanned systems. As the industry looks for partners outside of China, Taiwan naturally emerges as one of the most capable and reliable collaborators.

The convergence of robotics, semiconductors, and advanced manufacturing makes Taiwan a critical player in the future of drone technology.

Where the Future Is Being Built

The submersible flying drone may appear like a futuristic novelty today. But history suggests that technologies capable of solving real-world problems rarely remain curiosities for long.

As engineering barriers fall and new capabilities emerge, robotics continues expanding into environments once thought inaccessible. The boundary between air and water is just one of many frontiers now being crossed.

Some of the companies leading that transformation are emerging from places where deep engineering talent meets global manufacturing strength.

Increasingly, that place is Taiwan.

And the innovators building that future will soon be gathering in Silicon Valley.
