Remembering today, and don't let our greatest generation be lost and forgotten..the 2,404 service members and civilians who were killed during the Japanese attack on Pearl Harbor on December 7, 1941.
The infographic provides a timeline of key events on the morning of December 7, 1941, related to the Japanese attack on Pearl Harbor.
At 3:42 AM (Hawaiian time) the minesweeper USS Condor sights what may be a submarine periscope near the entrance to Pearl Harbor.
At 6:10 AM the first wave of planes, numbering nearly 200, takes off from aircraft carriers of the Imperial Japanese Navy’s Pearl Harbor Strike Force, which is positioned some 275 miles (440 km) north of Oahu.
At 6:45 AM the destroyer USS Ward fires on a Japanese submarine. These are the first shots fired by the United States in World War II.
At 6:53 AM the captain of the Ward radios the headquarters of the Fourteenth Naval District, responsible for defending the Hawaiian Islands, “We have attacked, fired upon, and dropped depth charges upon submarine operating in defensive sea area” near Pearl Harbor. The district commandant, assuming this to be an isolated incident the Ward and a relief destroyer can handle, takes no action. The commander of the U.S. Pacific Fleet decides to await confirmation before acting.
At 7:02 AM a U.S. Army radar operator on Oahu spots a large formation of unidentified aircraft heading toward the island.
At 7:20 AM an army lieutenant disregards this radar report, believing that it indicates a flight of U.S. planes, possibly B-17 bombers scheduled to arrive that day several hours later.
At 7:40 AM the first wave of Japanese aircraft reaches Oahu.
At 7:49 AM the first wave’s commander orders the attack on Pearl Harbor to proceed.
At 7:55 AM the coordinated attack on Pearl Harbor begins.
At 8:10 AM the battleship USS Arizona explodes.
At 8:17 AM the destroyer USS Helm fires on and sinks a Japanese submarine at the entrance to the harbor.
At 8:54 AM the second wave of Japanese planes, numbering nearly 170, begins its attack.
At 9:30 AM the destroyer USS Shaw explodes in dry dock.
At 10:00 AM the Japanese planes head back to their carriers, which will ultimately return to Japan.
The infographic provides a chart showing a block of red aircraft icons, each representing a single torpedo plane, high-level bomber, dive bomber, or fighter in the Japanese attacking force. According to the chart, a total of 353 planes were involved in the attack. Of those, 29 planes, shaded dark red on the chart, failed to return to their carriers after the attack.
The chart also notes that the Japanese navy’s Pearl Harbor Strike Force consisted of some 67 ships (6 of them aircraft carriers). Most of them were positioned more than 200 miles north of Oahu during the attack. Finally, the chart notes that only one Japanese ship that participated in the attack survived till the end of World War II.
