The Second Pearl Harbor: The West Loch Disaster, May 21, 1944

In May 1944, with American forces closing in on the Japanese mainland, the Fifth Fleet Amphibious Force was preparing to invade Saipan. Control of this island would put enemy cities squarely within range of the B-29 bomber. The navy had assembled a fleet of landing ship tanks (LSTs) in the West Loch section of Pearl Harbor.

On May 21, an explosion tore through the calm afternoon sky, spreading fire and chaos through the ordnance-packed vessels. When the fires had been brought under control, six LSTs had been lost, many others were badly damaged, and more than 500 military personnel had been killed or injured. To ensure the success of those still able to depart for the invasion-miraculously, only one day late-the navy at once issued a censorship order, which has kept this disaster from public scrutiny for seventy years.
