<div style="text-align: justify;"><span style="color:#00008B">The E-class harbor defense submarines were built to an Electric Boat Company design at the Fore River Shipbuilding Company in Quincy, MA. They were the first submarines in the USN to be powered by diesel engines, and the first to be equipped with bow diving planes. These two boats were originally named Skipjack and Sturgeon. On November 17, 1911, after launching but prior to being commissioned, the Navy changed its naming convention for submarines and these boats received their E-class names. Both boats were redesignated from their original general submarine designations to the new SS series on July 17, 1920.</span>

<div style="text-align: justify;"><span style="color:#00008B">The E-1 is seen here at an unidentified location, possibly Ponta Delgada, Azores, summer 1918. E-1 was a pathfinder, the first USN submarine with bow diving planes, seen here folded up alongside the forward superstructure. The bow planes were used to keep a precise depth, and the stern planes were used to control the up or down angle while running submerged. The E-class boats were also the first to have diesel engines. In this photo E-1 is either starting or finishing a long surface run, evidenced by the extensive bridge structure and the tall radio masts. All of this topside clutter would have to be disassembled and stowed below before the boat could dive, a process estimated to take at least 45 minutes.</span><br><br>
