When commercial games are doing something similar, this its very expensive, takes 100ds of manhours and is mostly done in cutscenes.
My advice is to rather show the aftermath of an airstrike with fires, smoke and debris. If you want to make THIS look convincing and your map actually resemble anything like Pearl Harbor, then you'll still be busy until christmas.
I am not teasing you, the research to recreate even a tiny part of a historical battle site takes several weekends and since the stock US soldiers are completely useless for a Pearl Harbor scenario you'll need another couple of weekends for the retexture work. Btw, I recommend the British stock soldiers as a base since the US forces used their steel helmet prior to entering WW2.
