While the Navy won’t start buying the new SSN(X) until 2034—and the new boat won’t become operational until 2044—the service has already started initial concept developments for the new submarine. One of the Navy’s major focus areas is propulsion, which is critical for ensuring that the new submarine is as quiet possible to defeat evermore-capable sonar. Read more
