Summary: The Skipjack-class submarine, operational from the late 1950s to 1990, marked a significant evolution in submarine design for the U.S. Navy, introducing a high-speed teardrop hull and nuclear power. This design originated from experiments with the USS Albacore, which aimed to enhance underwater speed and maneuverability through hydrodynamic testing. The Skipjack's streamlined shape and use of HY-80 high-strength steel set new standards in submarine construction, influencing not only subsequent U.S. naval designs...
