U.S. hands over files on sunken Soviet sub

The U.S. has handed over to Russia files from a Soviet submarine that sank in mysterious circumstances in the Pacific almost four decades ago. The declassified files were presented to the Pacific Fleet Museum in Vladivostok, Russia’s biggest naval base in

The Soviet submarine K-129 was on  patrolling duty in 1968 with 98 crew members aboard.

The cause of the sinking has never been determined.

In 1974, as part of a special operation codenamed “Jennifer”, the submarine was recovered by the American Glomar Explorer ship, 750 miles from Hawaii. However, the crew's families were not present at their burial.

A U.S. government spokesman said the materials can help the families solve the puzzle over the deaths of their loved ones.
