Cochino (SS-345) Tusk (SS-426) Two of the Navy's latest snorkel-type subs, the USS Cochino and the USS Tusk, are ordered to Arctic waters for cold weather operations. For days, the USS Cochino conducts submerged operations, her snorkel tube breathing oxygen for the diesel engines and men below. Suddenly, unexpectedly the hydrogen gauges register rising pressure. The sub is shaken by a loud explosion. The Cochino is jolted by blast after blast that tears at her midsections. Heavy smoke and flames envelop her. The crew works desperately to locate and clear the danger area. Power is lost. The explosions continue. The USS Tusk is signaled for help and stands ready to receive the men of the ill-fated Cochino.
