About Port Chicago Naval Magazine National Memorial

On July 17, 1944, a massive explosion jolted the San Francisco East Bay area, shattering windows and lighting up the night sky. At Port Chicago Naval Magazine, 320 men were killed instantly when two ships loading ammunition for Pacific troops exploded, resulting in the worst home front disaster of WWII. The aftermath illuminated the issues of segregation and racial inequality in the military.
