 back to oxygen, submarine designers turned their attention to vessels which could operate for long periods without surfacing. Veteran submariners visualized a new type of submarine in which surface performance characteristics would be completely subordinated to high submerged speed and agility. In 1949 a special committee began a series of hydrodynamic studies which led to a program within the IS Bureau of Ships to determine what hull form would be best for submerged operation.

 tested a series of designs. The best two—one with a single propeller and the other with dual screws—were then tested in a wind tunnel at Langley Air Force Base. The single-screw version was adopted, and construction of an experimental submarine to this design was authorized on 25 November 1950. This ship was classified as an auxiliary submarine (AGSS-569) and named Albacore.

The ensuing tests emphasized sound reduction and included extensive evaluation of Aqua-Plas, a sound-damping elastic which had been applied to the ship's superstructure and tank interiors.

Then, following evaluation of this new gear in the Gulf of Maine, the Albacore returned to Portsmouth on 30 September and went into reduced operating status pending the results of further studies on the feasibility of using her thereafter for further research.

 on 1 May 1980, and she was towed back to Portsmouth late in April 1984. When being towed to her drydock, the Albacore became stuck in the mud of Portsmouth Harbor. In 1985, she was dedicated as a memorial.

Albacores service as an active experimental submersible for more than two decades steadily increased the Navy's knowledge of both theoretical and applied hydrodynamics which it used in designing faster, quieter, more maneuverable and safer submarines. The Navy's effort to build hulls capable of optimum operation while submerged was wedded to its nuclear propulsion program in the submarine Skipjack
