Connecticut State Navy

The Connecticut State Navy was the colonial (and later, state) navy of Connecticut during the American Revolutionary War. Established in 1775, all of its ships were destroyed or captured by 1779. In the remaining years of the war a few smaller ships were commissioned to interdict smuggling between the Connecticut shore and Tory-controlled Long Island.

One the Connecticut Navy's most distinctive commissions was the Turtle, a submarine whose use in New York harbor in 1776 constitutes the first documented instance of submarine warfare.
