V-1 and her sisters V-2 (Bass) and V-3 (Bonita) were the only class of the nine "V-boats" designed to meet the fleet submarine requirement of 21 knots (39 km/h) surface speed for operating with contemporary battleships.
The latter were primarily for charging batteries, but to reach maximum surfaced speed, they could augment the mechanically coupled main-propulsion engines by supplying supplemental power to the 1,200 hp (890 kW) electric motors that were intended for submerged propulsion.
Although it wasn't until about 1939 that its problems were fully solved, electric transmission in a pure diesel-electric arrangement became the propulsion system for the successful fleet submarines of World War II, the Porpoise-class, and the Tambor-class through the Tench-class.
In January 1933 Barracuda was assigned to Submarine Division 12 and, until late in 1936, operated along the west coast and cruised to Pearl Harbor and the Panama Canal Zone with the fleet.
Between 15 December 1941 and 7 September 1942 Barracuda was attached to Submarine Division 31 and completed six war patrols in the Pacific Ocean, southwest of Panama, without enemy contacts.
Barracuda returned to Coco Solo, Canal Zone, on 7 September 1942 and, following voyage repairs, she proceeded to Philadelphia, Pennsylvania, for overhaul.
