A number of technological breakthroughs make our underwater warfare dominance possible. They included advanced acoustic surveillance techniques, on-board both surface and submerged ships, listening buoys, both fixed and free-floating, the sinusoidal equations that make the towed arrays viable even when not entirely straight in their deployment, the Greenland-Iceland-UK line, the acoustic emissions of our nuclear power plants, particularly the cooling pumps were so much lower than the Sov boats, the work of Drs Sheppard, Leventhal and Kowalsky, our Neuman-based computers that made US acoustic analysis so much more advanced their their, the sound-deadining tiles applied to the submarine hulls, the understanding of the critical speeds of the turning of Sov subs due to their sail design, and of course the pre-deployment information available from the UW taps at Murmansk and in the Sea of Okhotsk, and other items you are not cleared for.
More than anything else, however, it was the failure of the Soviet economic model to produce the financial foundation upon which to build a quality submarine force and the failure of Marxism-Leninism in general to produce a people educated enough and willing enough to crew such submarines on a career basis.
Of course the Soviet “Port Call” in Jacksonville late in the 20th Century and the defection-based intelligence learned from that was critically important, too.
Was there something else you wanted instruction in, Captain (HA!)
Typically, you take an ideological approach to everything, however, actually towards the end of the cold war, the quality of Russian Submarines was pretty high, and their nuclear propulsion and hull technology may have been superior to ours.
But up to the collapse of their economic system, our real advantage was the ability to implement real time digital signal processing on silicone integrated circuits because of rapid developments in integrated circuit technology. That is pretty much our principal technoligical advantage across the warfare spectrum even today, which is not irrelevant to the discussion at hand.
And to get back to basics you both called me a communist, even though you are trying the Obama defense, and you called me a phony.
PS, a lot of your list has nothing to do with ASW dominance.
