English: Supervisory Naval Architect Morton Gertler directs Instrument Maker Carson W. Caudle in preparing a model of the submarine for further tests at the David Taylor Model Basin, Carderock, Maryland, 1 March 1956. "This new type of submarine hull design was selected from a systematic series of streamlined bodies developed by Mr. Gertler, who also supervised the thorough development testing program that resulted in the hull and appendages as they now exist on the submarine Albacore." (quoted from the original picture caption).
