The following is a list based on research I have undertaken in an effort to determine what vessels were available historically within the region at this time. Some liberties have been taken in the interests of the AU, primarily the French and Italian presence in the region however I endeavoured to keep the IJN and USN forces as close to historically accurate. I have also taken some liberties in the strength of the RN Eastern Fleet.
I have excluded vessels smaller than destroyers and support ships from this list as well as merchant raiders as this is a list of warships in the region.
