Why Russia and China Feared America's Skipjack-Class Submarines

The Skipjack class was an example of how innovative new technologies can combine to produce a weapons system with vastly improved characteristics.
The Skipjack-class submarines were arguably the first truly modern postwar submarines of the U.S. Navy. Combining two new innovations—a new high-speed hull design and nuclear power—the innovative, fish-shaped subs were the basis of all future American submarines up to the present day.
The United States Navy officially entered the Nuclear Age on September 30, 1954. That was the day the USS Nautilus, the first nuclear-powered attack submarine ever produced, entered service. Powered by a S2W reactor, Nautilus had a virtually unlimited striking range. Nautilus was a technological triumph, heralding a new age in submarine warfare.
Although successful, Nautilus was a one-of-a-kind, proof-of-concept boat. The Skipjacks, with their improved S5W pressurized water reactors, introduced nuclear power to the bulk of the fleet. The S5W was a highly successful design that produced fifteen thousand shaft horsepower and was the standard U.S. Navy reactor until the introduction of the S6G reactor that powers the Los Angeles class. The reactor was also provided to the United Kingdom, where it powered the Royal Navy’s first nuclear powered warship, HMS Dreadnought.
Still, nuclear power represented just half of what the Skipjack class brought to the table. Although the Navy had introduced the nuclear-powered Skate-class subs to the fleet, they were built to a conventional design that made them more resemble late war submarines. As a result, their speed was limited to maximum of twenty knots. A new, hydrodynamic hull that would fully exploit the power of the reactor was needed.
In 1953 the Navy introduced a new diesel electric boat, the experimental research submarine USS Albacore. Albacore introduced a new teardrop-shaped hull, pioneered by legendary submariner Adm. Charles “Swede” Momsen. The symmetrical, tuna-like hull was a radical break from conventional, cigar-shaped hulls. While the Nautilus emphasized nuclear propulsion, Momsen wanted a submarine that was fast and agile.
