Much of season 2 features a cat and mouse game between the Nathan James and a rogue British submarine, with the Nathan James continuously frustrated in its efforts to locate, track and engage the enemy sub. Throughout it all Captain Chandler utterly fails to employ one of his most lethal anti-submarine warfare (ASW) assets - the MH-60R Seahawk helicopter that all Arleigh Burke-class destroyers of this type carry, and which were specifically designed for this purpose. Capt. Chandler only makes a couple casual references to the helo, almost as an afterthought, an omission that would constitute gross incompetence by a combatant commander. This failure is particularly egregious when the ship needs to quietly broaden its search area to locate the sub, get a targeting solution when it thinks it's located the sub, or later when the ship's own sonar has been damaged. While the MH-60R's capabilities are most effective when integrated with surface ships, the helicopter can conduct ASW search and destroy operations completely on its own (and can do so without compromising the ship's position) by deploying both passive and active sonobuoys, dipped sonar, advanced Periscope Detection and Discrimination capabilities, and dropping Mark 46 torpedoes on confirmed targets. Of course had Captain Chandler launched his Seahawk the enemy submarine story line would have been cut quite short.
