 She was the first woman to command a cruiser in the history of the U.S. Navy.
 Earlier, she had been the first woman in the U.S. Navy to command a destroyer when she served as skipper of the guided missile destroyer USS "Winston S. Churchill" (DDG-81).
 Her personal decorations include the Legion of Merit and the Bronze Star, among others.

 She was the first vessel on scene at the USS "Arizona", and was called off by the officers on deck because of the imminent explosion of the battery below deck.
 It then left and helped beach the USS "Nevada", with  , and YT-153.
 The beaching of the Nevada saved Pearl Harbor's mouth from being blocked.
 After that the USS "Nokomis" fought fires and dewatered the battleship USS "California", for 3 days.
 This effort made the "California" salvageable, to be recommissioned again later in the war.
 "Nokomis" was also the last vessel to move the surviving YC-699 barge prior to the Japanese attack on Pearl Harbor.
 Post-war she continued serving Pearl Harbor ships until she was decommissioned in May 1973, and eventually sold for "scrap" to Crowley, in San Francisco.

 In 1989, after the Loma Prieta earthquake in the SF Bay area, "Nokomis" and "Hoga" (which had been serving the City of Oakland as a fireboat) fought fires alongside each other again.
