She reported to the Second Submarine Flotilla, Atlantic Fleet.

Service history

Viper cruised along the Atlantic coast on training and experimental exercises until going into reserve at Charleston Navy Yard on 30 November 1909. Recommissioned on 15 April 1910, she served with the Atlantic Torpedo Fleet until assigned to the Reserve Torpedo Group at Charleston Navy Yard on 9 May 1911. On 17 November, her name was changed to B-1.

In April 1914, B-1 was towed to Norfolk, Virginia, and later loaded aboard the collier Hector for transport to the Philippine Islands. Arriving at Olongapo, Luzon on 24 March 1915, B-1 was launched from the deck of Hector on 15 April and recommissioned two days later.

B-1 was assigned to the First Submarine Division, Torpedo Flotilla, Asiatic Fleet on 19 May 1915 and later served with the Second Submarine Division in Manila Bay. On 1 December 1921, B-1 was decommissioned at Cavite, Philippine Islands, and subsequently used as a target.
