More than 50 Japanese ships and 230 total aircraft, 30 of which were American, were lost in the depths of the lagoon during the skirmish.Īn airplane gunner’s account of the operation helped Project Recover spot the U.S. Seventy-six years ago, the body of water was the site of Operation Hailstone, a two-day Allied air assault on a Japanese naval base.
