The New London (and it was in New London and not in Groton) Naval Underwater Sound Lab left a few years ago. Its existance was kept at a very low profile and its leaving was not very much contested. With 20-20 hindsight it probably was a sign of things to come -- or go. If you are in the SE Connecticut area, you might also want to pay this former high-security area a visit. The WWII-type buildings, where the real "action was" are gone and the olde Fort Trumbull is the main building here. It is just across the Thames River from EB.
FORT TRUMBULL'S HISTORY
By World War II Fort Trumbull had become home to the Coast Guard, the U. S. Maritime Service Officer Candidate School, and the Columbia University Division of War Research Underwater Sound Laboratory was established there.
In 1970 the Navy merged the Underwater Sound Laboratory at Fort Trumbull with the Underwater Weapons Research and Engineering Station, at Newport RI, forming the Naval Underwater Systems Center (NUSC).
In 1991 the Naval Underwater System Center in New London was renamed the Naval Undersea Warfare Center (NUWC).
STATE PARK DESCRIPTION
Fort Trumbull is not only the centerpiece of the newest state park, but also the only U.S. fort with a history stretching from the Revolution to the Cold War. The current fort, built in 1852, has served as a recruiting station during the Civil War, as the first U.S. Coast Guard Academy in 1915, and as the Naval Underwater Sound Lab during World War II. After a recent $25 million restoration, you can now track the fort's evolution. Visit officers' quarters and plot Benedict Arnold's movements, listen on a sonar device like the one invented here to detect enemy subs, and even design your own fort. There is also fishing from the pier, picnicking, and splendid views from the ramparts. Visitors' center and fort open Memorial Day-Labor Day daily 9-4. $5, ages 6-17 $2, 5 and under free. Park open daily 8-sunset. Free.
