New Suffolk, 1901

The submarine USS Holland (SS-1), the first commissioned submarine in the U.S. Navy, along with five other Holland Torpedo Boat Company-designed submarines of the Plunger class, were based in New Suffolk's Holland Torpedo Boat Station between 1899 and 1905, prompting the hamlet to claim to be the "First Submarine Base" in the United States. The location of the "submarine base" was on 1st Street between Main and King Streets.[3] The name of Mr. Holland's company was changed to Electric Boat during this time.[4]

In 2007, New Suffolk's two-room school house had nine students in grades K-6, making it one of the smallest school districts in the state of New York.


According to the United States Census Bureau, the hamlet has a total area 0.62 square miles (1.6 km2), of which 0.54 square miles (1.4 km2) is land and 0.04 square miles (0.1 km2), or 8.83%, is water.[2]
