US just unleashed the most dangerous 'hunter-killer' on earth

The US Navy commissioned the USS South Dakota on Feb. 2, 2019, and, in doing so, ushered in a new era of millennial undersea war fighters and the most technologically advanced submarine hunter-killer on Earth.

"I think we can honestly call South Dakota 'America's first millennial submarine' from construction to operation," Rep. Joe Courtney of Connecticut said at the South Dakota's commissioning.

While millennials across the board make up the majority of the US's combat service members in any service, the South Dakota was built by the shipbuilder General Dynamics Electric Boat, whose workforce is more than half millennial, The Day reported.


"The rise of the millennial generation emerging to lead Electric Boat's important work for the country, I believe, is a powerful rebuttal of cynics and naysayers that say that American manufacturing and technological excellence are a thing of the past," Courtney said.

The South Dakota is a fast-attack submarine, which trades the world-ending nuclear might of a ballistic-missiles submarine, or "boomer," for Tomahawk cruise missiles, mines, and torpedoes.

Boomer submarines hide in oceans around the world on the longshot chance the US may call upon them to conduct nuclear warfare. These submarines are not to be seen and avoid combat.

But fast-attack subs such as the South Dakota meet naval combat head-on.

Fast-attack submarines like the South Dakota serve as a door-kicker, as one did in 2011 when the US opened its campaign against Libya with a salvo of cruise missiles from the USS Michigan. These submarines also must hunt and sink enemy ships and submarines in times of combat, and the South Dakota is unmatched in that department.

Additionally, submarines make ideal vessels for deploying US Navy SEALs, who are trained in underwater demolition and can bring aboard their own mini subs for covert operations.

Finally, by laying down mines, the South Dakota can cripple enemy submarine and ship movement, a key element of naval war.

Unlike boomer crews, the South Dakota may be called up as the first line of defense in a fight with China or Russia. The US increasingly expects some confrontation with one of these near-peer powers.

Nonnuclear submarines, some of which China operates, have the advantage of being able to shut off their motors and run on battery power. US submarines are all nuclear, so they have to keep the reactor core on around the clock. The South Dakota mitigates this by adding extra insulation to the engine room.

"We are in a Great Power Competition with a resurgent Russia and a rising China. Our National Defense Strategy's first line of effort is to 'Build a more lethal' force because as it says, 'the surest way to prevent war is to be prepared to win one,'" Rear Adm. Leonard C. Dollaga, commander of the Undersea Warfighting Development Center, said of the South Dakota.

The South Dakota isn't the first of its kind, but it's the first to have new technologies such as large vertical sonar arrays, which the US says will give it an edge on Russian and Chinese ships.

Submarine combat is a very dangerous and tricky game. Any sonar or radar ping can reveal a sub's location, so the ships need to sit and listen quietly to safely line up a kill.

The South Dakota can detect ships and subs with an off-board array of sensors that it can communicate with in near real time. This represents a breakthrough in undersea warfare.

But submarines are only as good as their crews. The South Dakota will live or die based on its crew's ability to stick together and problem solve.
