Today the Naval Submarine Base New London (SUBASE NLON) is located on the east side of Thames River in Groton CT. All submariners in today's Navy will be stationed here for training and perhaps a tour onboard a fast attack submarine or with a pre-commissioning crew while their new submarine is under construction. SUBASE NLON is home to more than 40 tenant commands including the submarines and crews of Submarine Group TWO, the faculty and students of the Submarine School, and the Naval Submarine Support Facility (NSSF).
