GROTON, Conn. — affectionately known as "the Submarine Capital of the World" — is known for, well, submarines. The nautical town is home to Naval Submarine Base New London; 22 submarines; and the USS Nautilus, the world's first nuclear-powered submarine.

A team of 14 sailors from Navy Medicine Readiness and Training Unit (NMRTU) Groton conducted a pilot evolution to collect COVID-19 specimen samples for 165 submariners preparing to deploy from Naval Submarine Base New London.

The Virginia-class fast-attack submarine USS Colorado (SSN 788), homeported at Naval Submarine Base New London in Groton, Connecticut, participated in a unique submarine tradition during its maiden deployment in 2019.
