ThayerMahan, a high-tech vendor based in Groton, is positioning its innovative Outpost system as a solution to delays in U.S. submarine production, which has struggled with meeting the growing demand for undersea capabilities. The Outpost system, an unmanned surface vessel equipped with advanced acoustic sensors, can conduct undersea surveillance at a fraction of the cost of traditional submarines. Unlike a Virginia-class submarine, which costs up to $5 billion, an Outpost system operates efficiently with minimal personnel and provides near-real-time data from the depths of the ocean. ThayerMahan's system could extend the reach of submarines, enabling them to focus on other missions while ensuring undersea domains are monitored effectively.

The company has garnered support from lawmakers, including U.S. Rep. Joe Courtney, and the U.S. Navy, which has funded an independent study confirming that the Outpost system meets Navy requirements. ThayerMahan's cost-effective and scalable approach to undersea surveillance aligns with a broader need for more efficient defense technologies, particularly as the U.S. faces mounting production challenges exacerbated by the AUKUS agreement, which commits the U.S. to provide Australia with nuclear-powered submarines. ThayerMahan's system, with its potential for a government-owned, contractor-operated model, presents a disruptive opportunity to meet growing demands for submarine fleet expansion, with expectations for broader Department of Defense support by 2026.
