The aircraft carrier USS Gerald R Ford began its deployment in the North Atlantic Ocean on Tuesday, as the lead ship in a carrier strike group. The strike group includes six ships from NATO countries, several US warships and a submarine. We're going to use the entire Atlantic as our playpen, said Navy Captain Paul Lanzelata. He is the ship's commanding officer. The USS Ford is the world's largest warship. It weighs about 112,000 tons. The group will be carrying out several military exercises in the North Atlantic, said Vice Admiral Dan Dwyer. He is the commander of the US Second Fleet, which operates in the Arctic and North Atlantic oceans. Dwyer said, we can no longer assume that geography provides us with the protection that we've had in the past.
