The commanding officer of a Florida-based warship was removed from the post during an overseas deployment after several female crew members alleged that he sexually harassed women aboard ship, a Navy report shows. Cmdr. Derick Armstrong was relieved of command in May, about six months after his promotion to the top job aboard the guided-missile destroyer USS The Sullivans. Of the 1,500 commanding officers in the Navy, 22 were removed from the job last year for various reasons. Armstrong is among a dozen commanding officers removed so far this year.
