On Friday, President Obama nominated Vice Admiral Michelle Howard to be the vice chief of naval operations. If confirmed, Howard will not only be the first woman to become a full admiral, but will also be the first woman and the first African-American to hold the Navy's number 2 position.
This isn't Howard's first time breaking the glass ceiling. She was the first African-American woman to command a U.S. Navy warship, as well as the first to command an expeditionary strike group at sea. She was also the first female Naval Academy graduate to become a rear-admiral.
