Uss Narwhal (ssn 671)

USS Narwhal (SSN-671) was a unique nuclear-powered attack submarine commissioned by the United States Navy in 1969. As the lead and only ship of her class, Narwhal featured a quieter, natural circulation reactor design, making her one of the stealthiest submarines of her era. Throughout her service during the Cold War, she undertook numerous covert intelligence-gathering and special operations missions, earning a reputation for her advanced capabilities. After nearly three decades of service, USS Narwhal was decommissioned in 1999, leaving a legacy of technological innovation and clandestine contributions to U.S. naval operations.
