Chris Cahill is a US Navy Lieutenant. He is the communications officer on the USS Colorado.


The crew dance to "La Bamba" to celebrate crossing the equator but their revels are cut short by an incoming fire order. Captain Marcus Chaplin authenticates the order but is dubious of it's origin; rather than coming from Washington it was sent via Antartica, a route that is only supposed to be used if Washington is compromised. As they prepare to fire, Kendal suggests that they check the situation. Chaplin signals Cahill, who pulls up live television feeds and they are surprised to find America broadcasting as normal. Chaplin orders Cahill to radio Washington for confirmation of the order. Chief Joseph Prosser is quick to remind him that breaking radio silence is against protocol but Chaplin proceeds regardless.

Chaplin gets a response from Deputy Secretary of Defense William Curry; he is relieved of his command and Executive Officer Sam Kendal is told to proceed. When Kendal also asks for confirmation the Navy SEALs aboard storm the command room to try to force the crew to follow the order. Their action is cut short when the USS Illinos fires on the Colorado. The sub is able to dive before impact but still sustains damage and crashes onto the ocean floor.

Kendal delivers a rousing speech to his crew urging them to do their jobs to ensure they survive and promising that he will face up to the consequences of his questioning the order later. The Colorado records a nuclear strike against Pakistan. Chaplin resumes command of the boat over the protests of Cahill and Chief Prosser. Chaplin directs them to land on Sainte Marina, an island with a NATO station. He has his crew secure the station under his command.

Cahill is not at his post when Chaplin defends the island against bombers by launching a nuclear missile at Washington, DC. Chaplin detonates the missile 200 miles east of DC to prove that he will back up his threats.[1]
