by We’ve all read about ghost guns. But what about ghost subs? It turns out the newer classes of Russian submarines such as the diesel-electric Krasnodar are extremely quiet and are like noiseless spots in the ocean. The Wall Street Journal examines them as well as a deep-diving compatriot (Yasen class) in the video below. I wonder how much of the stealthiness of the Krasnodar was stolen technology courtesy of spys and/or traitors like the Walkers.
The Australian goes into much more detail in this story about the US Navy’s search for the Krasnodar in the Mediterranean Sea.
If the Russians have produced a quiet sub, it will be the first time.
If the Russian subs really are quiet, it's the fault of Aldrich Ames.
Toshiba and Kongsberg Vaapenfabrikk of Norway selling the Russians hi-tech submarine propeller milling machines and manufacturing secrets to increase the subs stealthiness certainly is a factor as well in their quieter sub manufacture.
