The U.S.S. Constitution, the oldest working warship in the world, is in drydock for a two year makeover. White oak planks and beams will be replaced using wood seleced by Navy Foresters. Affectionately known as "Old Ironsides," the ship was instrumental in winning the War of 1812 (it earned its name as its copper-covered sides repelled British cannon balls.) Crew dress in period uniforms and learn the peculiar requirements of maintaining an oak ship powered by the wind. About 12 percent of the ship is original wood.
