Here’s what life is like aboard the largest US Navy submarine

Submarines are a tremendous strategic and tactical advantage to countries that have them.

They range from small attack submarines used for naval and anti-submarine warfare to large ballistic-style submarines armed with nuclear weapons that could wipe out entire nations.

Launched in 1988, the Ohio-class USS Pennsylvania (SSBN-735) is currently the largest vessel in the U.S. Navy’s arsenal. It is 560-feet long and berths 165 sailors, according to the National Geographic video below.
