As part of the recent major refresh of its flagship SM300 marine autonomy system, Sea Machines has unveiled new Application Programming Interfaces (APIs) that enable approved third-party command and control (C2) system integration.

Sea Machines now offers two SMLink APIs that support a full spectrum of missions:

SMLink Streaming-API delivers real-time vessel telemetry and data feeds to external systems.
SMLink Control-API grants select partners the ability to command SM300 autonomy functions directly from third-party mission software.

“We’ve been listening to end-user customers and military procurement program offices globally, and we are pleased to continue to contribute to building a customer-first product and company. While our product has always had an open architecture, we’re now providing the keys for others to integrate. We hereby invite and challenge others to collaborate and build with us,” said Phil Bourque, VP of Global Sales, Sea Machines.

The SMLink APIs are available with both updated SM300 models: the SM300-SP, tailored for fast, attritable USVs and programs prioritizing volume and efficiency, and the SM300-NG, built for complex, high-specification projects aboard classed vessels.

With more than 200 SM300 deliveries across 20 countries, Sea Machines has established itself as a proven leader in defense-ready marine autonomy. The SM300 is a software-enabled edge computing system that fuses with mission management tools while delivering both low-level vessel control and higher-order autonomous behaviors, even in GPS or communications-denied environments.

Headquartered in the United States with offices in Europe, Sea Machines supports naval and defense customers worldwide.
