First Lady Michelle Obama is sponsoring an all female Navy submarine. The USS Illinois Twenty is expected to enter service in 2015. It's a Naval tradition that first ladies sponsor a submarine; Laura Bush and Hillary Clinton are among those who've sponsored in the past.

The idea is that the first lady's spirit will guide the ship and the crew throughout the lifetime of the ship. Obama says it a, quote, "honor and a privilege" to sponsor the submarine, calling it a, quote, "tribute to the strength, courage, and determination" that naval families exhibit every day.
