The Navy Has One Nuclear Spy Submarine So Secret We Know Almost Nothing About It

The USS Jimmy Carter is one of a kind. 

The unit makes no mention of intelligence gathering. But while the name implies a solely experimental function, the sailing branch routinely uses these types of monikers for special or elite groups. The near legendary terrorist-hunting SEAL Team Six is officially called the Naval Special Warfare Development Group. The service describes the  spy ships  it runs together with the U.S. Air Force as “missile range instrumentation ships.” The squadron responsible for flying around the president and his staff is now simply called Marine Helicopter Squadron One, but still uses the acronym HMX-1—a nod to its “experimental” origins.

On January 20, 2013, the  Seawolf-class attack submarine USS  Jimmy Carter  left her home port in Bangor, Washington. Less than two months later, the submarine appeared at Pearl Harbor in Hawaii for repairs.

It was all quite mysterious. During her time at sea, we don’t know where  Jimmy Carter  was or what her crew of nearly 150 were precisely doing. The  Seawolf class is one of the most secretive weapons in America’s arsenal, and information about the Navy’s “Silent Service” is difficult to discover. . . by design.

(This first appeared in 2016.) 

We know  Jimmy Carter  was on some kind of mission, which the ship’s  official annual history  vaguely referred to as Mission 7. “Performed under a wide range of adverse and extremely stressful conditions without external support, this deployment continued USS  Jimmy Carter ‘s tradition of excellence in pursuit of vital national security goals,” the history stated.

In this vessel’s official chronology, the mission warrants as much mention as a picnic in July and the crew’s Halloween party three months later. But Mission 7 was enough to earn the sailors a Presidential Unit Citation, which rewards “extraordinary heroism in action against an armed enemy,” according to an  official Navy description .

As the last of the  Seawolf-class attack submarines,  Jimmy Carter  is unique. During her construction, the Pentagon added a special one-hundred-foot-long, 2,500-ton module called the Multi-Mission Platform. By the sailing branch’s  own admission , this space can accommodate undersea drones, SEALs and much more.

More importantly, the hourglass-shaped section might allow specially trained teams to find and tap undersea communications lines and plant listening devices on the ocean floor. It’s more than likely that the submarine is one of the Pentagon’s most stealthy spies.

Another clue is the Presidential Unit Citation for Mission 7. For the sailing branch, this is akin to giving the boat itself a Navy Cross, the service’s second highest award. The criteria makes it clear that the mission must have been “extremely difficult and hazardous.” But the Secretary of the Navy’s citation for the sub’s 2013 performance is equally obtuse.

Along with sailors from the even more obscure Detachment Undersea Research and Development,  Jimmy Carter  “successfully completed extremely demanding and arduous independent submarine operations of vital importance to the national security of the United States,” is how the memo described the operation. Both units “overcame numerous obstacles to safely execute these demanding and complex tasks without incident.”

Two pictures attached to the report show the ship’s captain, Cmdr. Brian Elkowitz, and other officers holding the framed citation and associated pennant. In both cases, Navy censors blacked out one individual’s face, ostensibly for privacy reasons.

War Is Boring  obtained these documents through the Freedom of Information Act. Every year, all ships, subs, squadrons of aircraft and commands on land are required to turn a historical report over to the Naval History and Heritage Command in Washington, D.C. But there’s no requirement that the narrative go into any great or specific detail. And  Jimmy Carter ‘s history is more a record of the secrecy surrounding the ship’s than her actual activities.

While already guarded about submarines in general, the Navy is especially tight-lipped about the  Seawolf-class boats. Originally intended to be the most advanced undersea attackers, Washington slashed the program after the Cold War and the threat of equally high-tech Soviet submarines appeared to evaporate.

Instead of a planned fleet of nearly 30 ships, the Pentagon bought just three for more than $3 billion each. At more than 350 feet long and with a submerged displacement of more than 9,100 tons, the  Seawolf class is the most expensive attack submarine ever built and the second most expensive undersea vessel of any type.

The sailing branch eventually grouped together the USS  SeawolfConnecticut and Jimmy Carter  as the core of Submarine Development Squadron Five. The unit’s spartan Web site states it is responsible for testing new undersea listening gear and remote-controlled submersibles, either tethered to a larger sub or able to operate on their own.

The group is also in charge developing new tactics for  fighting in the Arctic , a region where submarines can easily hide from their opponents. Despite their current mission, each ship still has eight torpedo tubes, which can also fire Harpoon anti-ship and Tomahawk cruise missiles.
