Testing of "silent" propulsion systems to reduce acoustic signatures high-speed nuclear vessels.

The auxiliary research submarine program was pivotal in transitioning the Navy from World War II-era "fleet boats" to modern, high-speed nuclear vessels. By using these ships as "laboratories at sea," the Navy could test radical innovations—such as the teardrop hull—without risking the performance of the active combat fleet. 🏗️ Technical Specifications & Role

: As the Navy moved toward nuclear power, AGSS vessels like the USS Salmon were used to test remote-control operations and advanced sonar for the new SSN classes.

Two ships stand out as the most significant examples of this class:
