Here are two maps of Pearl Harbor. The first shows the placement of the U.S. Fleet on December 7, 1941, while the second is a photo of what Pearl Harbor looks like today.
In the photo below, while some of the hangars remain on Ford Island, the Naval Air Station is no longer an active Navy airfield. Prior to 1998, the only way to reach the island was by ferryboat. Now a bridge links the island to Oahu.
