Lots of critical thinking went into design and construction. Hats off!

Nuclear attack submarine USS Colorado (SSN-788) is scheduled to be commissioned during a Saturday morning ceremony at the Naval Submarine Base New London in Groton, Conn.

Construction of Colorado started in 2012 and is the 15th Virginia-class fast attack submarine, and the fifth Virginia-class Block III submarine to be built. Colorado will be the fourth U.S. Navy ship commissioned named for the state of Colorado.
