USS E-1
1911 E-class submarine

USS Skipjack/E-1 (SS-24), also known as "Submarine No. 24", was an E-class submarine of the United States Navy (USN). She was the first boat in the USN named for the skipjack, though she was renamed E-1 prior to commissioning. She was the first American submarine to be powered by diesel engines. E-1 served in patrol duty in the waters around the Azores, during WWI.

Skipjack was laid down on 22 December 1909, by the Fore River Shipbuilding Company, in Quincy, Massachusetts. She was launched on 27 May 1911, sponsored by Mrs. Donald R. Battles. She was renamed E-1 on 17 November 1911; and commissioned on 14 February 1912, with Lieutenant Chester W. Nimitz in command.

Why this record matters
A short description can identify a subject without explaining its stakes. For “USS E-1”, the useful work is to connect “1911 E-class submarine” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 19, 2026. The linked authority identifier is Q7869000. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1909, 1911 and 1912.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
