“Welcome Aboard!” Congratulations on your orders to NIOD GROTON, home of the finest Sailors in the fleet.
NIOD GROTON provides cryptologic direct support systems installation, maintenance, and personnel augmentation support to U.S. Fleet Forces Command submarines.
Personnel with orders should be in constant contact with their command-assigned sponsor. If you have not received a Welcome Aboard package from your sponsor, please give the Command Career Counselor a telephone call at (860) 694-3147 or email him at NIODGTN_NWLN_COMMAND_CAREER_COUNSELOR@navy.mil. You and your sponsor should coordinate any necessary travel arrangements to get here safe and sound.
Once in the Groton area, report to the Submarine Base New London. If you arrive during normal working hours (0700-1530), report to the NIOD Groton Quarterdeck in person with your orders. If you arrive after hours, please telephone the NIOD Groton Quarterdeck at (860) 625-1994 and leave your arrival information to include Name, Rate, the date, and your arrival time.
The next business day, you will report to the command at 0700.
If you are a new check-in and you have not yet received a command sponsor, please email us at
