On December 7, 1941, the US naval fleet stationed at Pearl Harbor, Hawaii, suffered a devastating attack from the air and sea.
The Japanese assault began around 8 a.m., resulting in the deaths of 2,403 Americans, numerous injuries, and the sinking of four battleships and damage to many more.
Surprised US service members who normally would have slept in on that Sunday morning or enjoyed some recreation found themselves fighting for their lives.
In 2013, the US Navy remembered the "day of infamy" with a series of photo illustrations overlaying scenes from that horrifying date with present-day photos.
Now, 77 years after the attack, here's what Pearl Harbor looked like then and now.
