 Current Navy vessels have no ice protection, they're very thin hulled and ice can be very damaging to a ship that is not properly protected to operate in the vicinity of ice. So our overarching goal of the Arctic and Global Prediction Program to improve our ability to forecast and predict where the ice is at any moment is very important to the Navy so that if vessels are up there the captain knows where the ice is and where to avoid, where not to go or where he can go to operate safely and effectively.
