An iconic United States military ship that was sunk by a German submarine in World War I has been discovered by a diving team off the coast of Britain over a century after it was lost, officials revealed Wednesday. The sinking of the Coast Guard Cutter Tampa in 1918 in the Bristol Channel killed 131 service members, the largest loss of life on any U.S. combat ship during the war. The long-lost vessel was found by the British diving team Gasperados about 50 miles off Cornwall more than 300 feet
