Umiak I is the most powerful ice-breaking bulk carrier in the world, and she has to be in order to survive the rough seas and thick ice off the eastern coast of Canada. She is the lifeline to the remote Voisey's Bay Nickel Mine in Labrador. Her job is to deliver desperately needed supplies and return home with 30,000 tons of nickel concentrate, worth over $120 million. Hop aboard and join her fearless crew on a treacherous mission, featuring heavy fog, howling winds, towering waves, and volatile cargo in constant need of monitoring.

Guided-missile destroyer USS Gravely is the very definition of a fighting ship. She's the youngest warship in the US Navy's fleet and you've been granted exclusive access to see her in operation. When called into duty, she'll be armed with everything from Tomahawk cruise missiles to attack helicopters, but for now, she and her crew must prove they are combat-ready. Witness the live-fire training exercises they go though, and see how she weathers the storm of simulated air and sea attacks, fires and an unexpected visit from a wandering civilian vessel.
