The United States naval base at Pearl Harbor was surprised by a Japanese military strike on the morning of December 7, 1941: all eight U.S. Navy battleships were damaged, more than 2,000 Americans lost their lives, and this very attack led to the American involvement in World War II. Today, a memorial reminds of those who died in the assault, while two museums and outdoor exhibits present the historical happenings and their backgrounds. The visitor centre in general also features exhibits and interpretive programs for other Pacific National Parks: Kalaupapa National Historical Park on the island of Molokai, American Memorial Park in Saipan, and War in the Pacific National Historical Park in Guam.
