"Magnus Nordenman explores the emerging competition between the United States and its NATO allies and the resurgent Russian navy in the North Atlantic. The new battle for the North Atlantic involves an overstretched U.S. Navy, the rise of disruptive technologies, a NATO unprepared for high-end warfighting in the maritime domain, and a Russia commanding a navy equipped with long-range cruise missiles. Nordenman also provides a set of recommendations for what the United States and NATO must do now in order to secure the North Atlantic in this new age of great power competition."--Provided by publisher.
