USS B-1 (SS-10) was the lead ship of her class of submarines built for the United States Navy in the first decade of the 20th century.

[2] For surface running, they were powered by one 240-brake-horsepower (179 kW) gasoline engine that drove the single propeller shaft.

Viper cruised along the Atlantic coast on training and experimental exercises until going into reserve at Charleston Navy Yard on 30 November 1909.

In April 1914, B-1 was towed to Norfolk, Virginia, and later loaded aboard the collier Hector for transport to the Philippine Islands.
