Russian navy frigate conducts drills in Atlantic, defence ministry says

Russia's Admiral Gorshkov navy frigate, which visited Cuba earlier in June, conducted anti-submarine drills in the Atlantic Ocean using a helicopter, the defense ministry announced on Tuesday. The helicopter's crew practiced tactical techniques for locating and tracking submarines more than 50 kilometers (31 miles) from the ship, making a total of five landings on the frigate's deck. The drills followed the frigate and the nuclear-powered submarine Kazan's training in the Atlantic, including high-precision missile weapons exercises, before their arrival in Havana harbor on June 12.
