USS South Dakota could give US forces edge against North Korea

Some military experts believe the newly-christened USS South Dakota submarine could give US forces the edge against North Korea.
If deployed in the Pacific, the South Dakota will likely sail near the Korean peninsula to counter an ambitious submarine program developed by Kim Jong Un.
Experts say the sub's advanced stealth capabilities could make the difference between life and death.
"The humans that live on board them are trained to be quiet so that they put the least amount of noise into the water. We often joke, with regard to diesel-electric boats, when people ask us, 'well how loud are they'? And we always ask, 'well how loud is your flashlight?'" former Navy submarine hunter, Captain Jerry Hendrix said.
