The hunt for Red October - Groton Connecticut

Groton is sometimes referred to as the "Submarine Capital of the World," due to the long-standing history of submarines in the town, and the fact that Groton has one of the largest submarine bases in the world. The National World War II Submarine Memorial East is located in Groton, including parts of USS Flasher.

There are two major companies in Groton: General Dynamics Electric Boat and Pfizer. The Electric Boat plant on the eastern shore of the Thames River employs 10,500 people in the community.
