The USS Dolphin was the Navy’s last diesel-electric deep-diving research boat.

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
