The milestone comes two years after the Defence POW/MIA Accounting Agency dug up nearly 400 sets of remains from a Hawaii cemetery.
Officials exhumed the bodies after determining that advances in forensic science and genealogical help from families made it possible to identify the men. The buried Marines and sailors have been classified as missing since World War II.
The agency has said it expects to identify about 80 percent of the battleship's missing crew members by 2020.
