A Russian spy ship has reappeared off the U.S. eastern seaboard, sailing just 20 miles south of the U.S. Navy submarine base at King’s Bay, Georgia, and heading north.

CBS News correspondent David Martin reports the Viktor Leonov, known as an AGI (Auxiliary, General Intelligence) trawler, has a port call scheduled in Jamaica for mid-April, and the assumption among U.S. officials is that it will make one more run up and down the east coast before heading to Jamaica.

They Leonov made a similar journey along the East Coast in February, sailing close to a U.S. naval base in Virginia and Naval Submarine Base New London in Connecticut, which the Navy describes as the “Home of the Submarine Force.”

During its February patrol of the East Coast, the closest the ship came to land was 17 miles, which is still in international waters, Martin reported.

Its voyages are the latest in an alarming string of incidents involving the Russian military. In February, a group of Russian jets buzzed a U.S. destroyer in the Black Sea and the U.S. accused Russia of secretly deploying cruise missiles capable of carrying a nuclear warhead in violation of a major arms-control treaty.

As the Leonov patrolled in February, CBS News chief White House correspondent Major Garrett asked President Trump about the incidents during a nationally broadcast press conference. READ MORE
