A U.S. military helicopter prepares to take off from the deck of the French navy aircraft carrier Charles de Gaulle in the Persian Gulf on Thursday, March 19, 2015. The Charles de Gaulle, France's only aircraft carrier and the flagship of the French navy, arrived in the Persian Gulf last month to help provide additional air power to the U.S.-led coalition conducting airstrikes against the Islamic State militants who have seized a third of Iraq and Syria.
