At what Navy Command did Admiral Ben Moreell serve during the formation of the Seabees?

Admiral Ben Moreell served at the Bureau of Yards and Docks during the formation of the Seabees. This command played a crucial role in overseeing the construction and engineering facets of the Navy, particularly in World War II when the Seabees were established to provide combat support and crucial logistical support in various theaters of war. The Bureau of Yards and Docks was integral in the development of policies, training, and the organization necessary for the establishment of construction battalions.

In contrast, the Naval Construction Battalion, while an important part of the Seabees, came into existence as a direct result of the decisions and policies initiated by the Bureau of Yards and Docks. The other commands listed – Naval Sea Systems Command and Naval Facilities Engineering Command – did not exist in their current form during the time of the Seabees' formation, focusing instead on systems and engineering functions established later.
