State of War (March 7, 2015)

After negotiations with the Klingons break down, the USS Enterprise is sent to block Klingon expansionism on the Class M planet Organia, described by Spock as class D- on the "Richter scale of culture." After being attacked, the Enterprise destroys a Klingon vessel. Shortly thereafter, Uhura reports that a state of war has been declared between the Federation and the Klingons.
