According to Unalaska residents, an American submarine that stopped by Dutch Harbor to offload some scientists caused a stir in town Thursday with rumors out about it being a Russian sub with engine or heating problems. But it seems that wasn't the case. It is supposedly a U.S. Navy Los Angeles class submarine dropping off scientists who had spent the past few months in the Arctic.
