As more than 100 ships and submarines from World War II rest in neighboring waters, the area is known to attract salvage companies in search of steel, aluminum, and brass.

Two years ago, the US military reported an "unauthorized disturbance" at the wreck of the USS Houston in the Java Sea, while the New Straits Times reported last year that men were using explosives to rip apart wrecks for their metal.

Apparently a lot of them are less than 300ft down. They're using explosives to break them down and grabs to haul them up. Also, the missing is up to 6 now;
For 74 years, six WWII ships rested at the bottom of the ocean. Then they vanished.
