The second highest medal that can be awarded by the United States Navy, Marine Corps and Coast Guard. Awarded to any person who, while serving with the Navy, Marine Corps or (in time of war) Coast Guard, distinguishes himself in action by extraordinary heroism not justifying an award of the Medal of Honor. The action must take place under one of three circumstances: while engaged in action against an enemy of the United States; while engaged in military operations involving conflict with an opposing foreign force; or, while serving with friendly foreign forces engaged in an armed conflict in which the United States is not a belligerent party. To earn a Navy Cross the act to be commended must be performed in the presence of great danger or at great personal risk and must be performed in such a manner as to render the individual highly conspicuous among others of equal grade, rate, experience, or position of responsibility. An accumulation of minor acts of heroism does not justify an award of the Navy Cross. As originally authorized, the Navy Cross could be awarded for distinguished non-combat acts, but legislation of 7 August, 1942 limited the award to acts of combat heroism.
