Warpboost, your information on IVY BELLS is partially correct:
The operation occurred in the Pacific ocean near Vladivostok, and the cables that were tapped were unencrypted land-lines that were strung across a
large bay and series of islands where the Soviets had a major military presence. The US Navy sent in specially equipped subs, which found the buried
cables in the ocean floor (they first located the junction box on the beach, which indicated the location of where the cable went underwater - give
you an idea of how close to land they operate!). Then SEAL divers planted recording devices on these cables, and reburied them in the ocean floor.
Months later, the sub would return, replace the old device with a ne w one, and slip away. The tapes would then be sent back to NSA for analysis.
The operation was a success because the Soviets (who could blame them) believed it was unnecessary to encrypt the signals running through these
cables, as they were in protected Soviet waters and underground.
In 1981 the Soviets learned of the operation do to a spy at the NSA, Ronald Pelton, who compromised the operation. Fortunately, the US sub never had
to go back a try to retreive the compromised pod, as NRO recce photos of the area clearly showed the Soviet Navy in the area of the surveillance pod,
conducting a salvage operation. The NRO passed this data to the CIA, who then told the Navy, who then went to investigate when it was all clear.
Sure enough, the lat pod was gone - the Russians had taken it. Eventually the spy pod was put on display in Moscow, to embarass the US (we were not
embarassed!).
A great deal of valuable tactical and strategic information about the Soviet military forces in the Pacific was gleaned by this operation, and it all
went into the dumper because of one lousy criminal traitor who wanted money.
A great synopsis of the event can be found

Siberian Tiger: maybe you could grace us with one of these infamous pictures of the Statue of Liberty or the Golden Gate Bridge (through a russian
periscope, of course), which you proport to exist?
