Ultra Maritime Tests Sea Spear Sonar in U.S. Navy Lanternfish Exercise

The demonstration proved the system could consistently track medium- and large-diameter UUVs in a realistic port protection scenario. By transmitting live acoustic track data to command centers, the technology aims to solve the persistent problem of maintaining undersea awareness in high-traffic or contested maritime zones. This trial served as a high-stakes proving ground for the company’s push into autonomous, scalable surveillance.

A key component of the demonstration involved integrating Sea Spear with Anduril’s Seabed Sentry. This collaboration creates a distributed network capable of being launched from either manned or unmanned platforms. Because the system can function as either a permanent installation or an attritable asset, it offers naval commanders a flexible alternative to traditional, static sensor arrays. As undersea threats become more sophisticated, this shift toward autonomous, deployable networks provides a new layer of resilience for maritime defense missions across global waterways.
