Here, the USS Zumwalt class' is pictured as what looks like a military mining operation in the South Georgia and South Sandwich Islands for rare earth metals such as Neodymium and Gadolinium. Just an educated guess.
The USS Zumwalt is the first of a new class of United States guided missile destroyers. It is designed to operate in both the open ocean and in shallow, coastal waters, makes 30+ knots, and incorporates stealth features such as a wave-piercing hull that leaves almost no wake, exhaust suppression to reduce its infrared signature; and an steeply sloping exterior, creating a radar signature said to be equal to a small fishing boat. The planned service date is 2015.
