Map recreates US naval base of the WWII times - at least the creator of the map claims so. You can discover a lot of stuff there: different models of aircraft and ships, from small to big, airfield, hangars and docks. I'm not competent enough to say, whether this models are historically accurate, but they are looking quite realistic. Map can evoke patriotic feelings, which always a good thing.
