The Japanese land-land based air groups played a key role during the Pacific War.
Many islands became fixed aircraft carriers from where the air groups operated protecting the defensive perimeter of the Empire of Japan during the World War II.
In this page, I summarize the main naval air groups that were operative during the early days of December 1941. I would like to extend this research in future updates so stay tuned on this if you are interesting in the historical development of these units. See the page here.
