In short: Uncrewed surface vessels, or USVs, are robotic boats that roam the ocean without a human aboard. By utilizing renewable energy like wind and solar, these versatile machines can conduct long-term missions in harsh environments, collecting vital atmospheric and oceanic data while keeping human researchers safe on dry land.

Uncrewed surface vessels are highly adaptable tools that come in diverse forms, ranging from small surfboard-like devices to 22-meter-long vessels. Their design is dictated entirely by their mission, with configurations tailored for specific tasks such as mapping the seafloor, tracking marine life, or monitoring ocean acidification. While some are purchased off the shelf, others are custom-built to meet unique operational requirements. These vessels can function independently, in groups, or as support platforms for underwater vehicles, providing them with navigational guidance and real-time communication links.

The efficiency of USVs stems from their ability to operate without the logistical constraints of crewed ships. By removing the need for human life support, these vessels can access remote or hazardous locations, such as the interior of a hurricane or the Arctic seabed, for extended durations. Many modern USVs, such as Saildrones and Wave Gliders, leverage renewable energy sources like wind, solar, and wave power to remain at sea for months or even up to a year. This persistence allows for continuous data collection that is significantly more cost-effective and environmentally friendly than traditional ship-based operations.

Despite their growing capabilities, USVs are not intended to replace human-crewed ships or underwater systems. Instead, they function as part of a collaborative ecosystem, balancing the strengths of different technologies to increase the scale and pace of scientific discovery. Beyond research, the technology is expanding into commercial sectors, including cargo transport and passenger ferries. As control systems advance, these vessels are increasingly capable of fully autonomous navigation, though they remain subject to complex engineering challenges, such as managing propulsion responses and ensuring safety in diverse maritime environments.
