USS Sturgeon/E-2 (SS-25), also known as "Submarine No. 25", was an E-class submarine of the United States Navy (USN). She was the first boat of the USN named for the sturgeon, though she was renamed E-2 prior to commissioning.
The analysis highlights History and Measurement as prominent areas in the source structure around USS E-2.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
