US Navy needs 66 attack submarines but fleet could fall to 46-47 by 2030

 The USS San Juan submarine retired after thirty-eight years of service. Aging submarines are leaving service faster than new ones are delivered. This creates a significant gap in the United States attack submarine fleet. Production challenges and other naval programs compound the submarine shortage. The US Navy faces growing demands from global adversaries and allies. The USS San Juan submarine retired after thirty-eight years of service.
