ROCS Su Ao (蘇澳, DDG-1802) is a Kidd class guided-missile destroyer currently in active service of Republic of China (Taiwan) Navy. Su Ao was formerly USS Callaghan, which was decommissioned by the U.S. in 1998. For some time, Su Ao was tentatively named Ming Teh (明德), following the example of Chi Teh (紀德), but it was later decided to be named Su Ao, after the Su-Ao naval base in eastern Taiwan.
