Poka Ailana or Ford Island is a 441-acre island located in the heart of Pearl Harbor. It was formerly known as Moku'ume'ume, meaning 'the Island of Games.' Ancient Hawaiians used the place for mate swapping, but this game practice was brought to an end by the Western Christian missionaries. In the following years, the island took various names and changes. In the mid-1800s, it was named 'Ford Island' in honor of a prominent Hawaii physician, Dr. Seth Porter Ford. US Navy acquired the island for a base station in 1936, but due to modernization in the naval aircraft post the war, the Air station wasn't necessary. Ford Island plays a significant role in the Pearl Harbor attack. The island today is home to numerous military residents and a National Historic Landmark.
