Design, Construction, and Naming Notes
They conducted brief anti U-boat patrols off the New England coast in WWI, and then served in a training role out of New London until they were decommissioned. Overall, these boats ended up being too small to be really useful, with the EB versions averaging only 8.5 years of service. The Lake versions seemed to have been particularly disliked for poor detail design, habitability, and overall unreliability. They were discarded after only 3.5 years of service in the early 1920's. However, the Busch-Sulzer 6M50 diesels of the Lake N's were well liked. The engines from N-4, N-5, and N-7 were removed and installed on three of the EB design L-boats, as their engines were worn out by 1923.
N-1 (Submarine No. 53, later SS-53)

Behind, on the shore, can be seen the Fort Griswold Monument and Fort Griswold itself, to the left of the large smoke stack. Fort Griswold is a revolutionary war fort that was the scene of a bloody massacre by the British on American forces. Survivors were taken from the fort and placed on prison ships moored in the Thames River.
The building with the large smokestack is yet to be identified. It is north, or upriver from the present location of the Electric Boat Company where submarines are still built.N-2 (Submarine No. 54, later SS-54)
