"The only ship of her class, Enterprise is the second-oldest vessel in commission in the United States Navy, after the wooden-hulled, three-masted frigate USS Constitution."
"She was originally scheduled for decommissioning in 2014 or 2015, depending on the life of her reactors and completion of her replacement, USS Gerald R. Ford. But the National Defense Authorization Act for Fiscal Year 2010 slated the ship's retirement for 2013, when she will have served for 51 consecutive years, the longest of any U.S. aircraft carrier."
