Historic overview:

Operation codename: Brewer Admiralty Islands fulfilled all requirements. Be an ideal natural harbor Seeadler, 6 miles wide, 20 miles long and 40 meters deep horseshoe-shaped bay, limited by two main islands of Manus and Los Negros. There was also the possibility of modifying the existing Japanese airports and build new ones. The strategic location of the islands allows them to create more significant part of the chain closing the encirclement of Japanese garrisons on New Britain and the Solomon Islands. Occupation of the Admiralty islands would seal the neutralization of Rabaul.
