A '''submarine''' is a vehicle that travels under water (i.e. an underwater boat).  The submarine was invented in the 17th century. Though it was originally designed for the purpose of exploration, its military benefits soon became clear. The first military submarine was the Turtle which was used by the Colonists during the [[American Revolution]], although without success.

The "N" refers to nuclear propulsion, not necessarily nuclear weapons. An SSBN is capable of being armed with nuclear missiles while an SSGN is designed to carry up to 154 Tomahawk cruise missiles. SSN's are capable of carrying Tomahawks, but only a very limited number of tubes.  The SSGN has 8 tubes that can be reconfigured to support Special Operations Forces in a variety of roles.

According to the National Interest website: "The Ohio-class boats may be the most destructive weapon system created by humankind. Each of the 170-meter-long vessels can carry twenty-four Trident II submarine-launched ballistic missiles (SLBMs) which can be fired from underwater to strike at targets more than seven thousand miles away depending on the load."<ref>[https://nationalinterest.org/blog/the-buzz/attack-just-one-these-us-nuclear-submarines-would-destroy-23359 An Attack from Just One of These U.S. Nuclear Submarines Would Destroy North Korea], National Interest website, 2017</ref>]]
