The 1939 scouting force contained Pensacola, Northampton, Portland, and New Orleans-class heavy cruisers, supported by patrol aviation and tenders such as Sandpiper and Teal. Without fleet carriers, it was not the fleet's primary reconnaissance system in the modern sense. Seaplane units could operate from islands and inlets while tenders created temporary operating bases, extending surveillance beyond the cruisers' own aircraft. Its composition fits a distributed control force able to patrol sea areas, protect trade, and project independent cruiser power.
