She holds the record for firing the most ammunition of any American ship during WWII, firing nearly 2 million rounds through 7 different types of guns while training an estimated 35,000 anti-aircraft gunners. All without a single personnel casualty.  (National Archives Photo, Wyoming State Archives Sub Neg 15436, WYSHP-1)
