What USS Albacore could teach a 1937 submarine program

How would sending USS Albacore back to 1937 affect American submarines?

It could accelerate teardrop-hull and machinery development, but practical derivative boats would probably not appear until 1941-42.

Albacore's teardrop hull and diesel-electric equipment could accelerate American long-range submarine development. Her crew would be as valuable as the hardware because they could explain how the design was intended to operate. The boat would not supply a modern torpedo system ready for direct copying. Reproducing the transferable technology would still take years, making 1941-42 a more plausible arrival for derivative boats than an immediate prewar transformation.
