The Echo class were nuclear cruise missile submarines of the Soviet Navy built during the 1960s. Their Soviet designation was Project 659 for the first five vessels, and Project 675 for the following twenty-nine. Their NATO reporting names were Echo I and Echo II. All were decommissioned by 1994.[1][2]
