Apart from the changes in the personnel of the Board itself and a slight rearrangement of their duties and those due to the establishment of an Air Ministry (which had been arranged by the Cabinet before December, 1917), there were but slight alterations in the organization shown in Table A [above], as will be seen by comparing it with Table C on p.

27 [below], which indicates graphically the organization given in the Admiralty communique.
TABLE C FIRST SEA LORD AND CHIEF OF NAVAL STAFF.
Deputy Chief of Naval Staff.
Director of Signals Division.
Director of Operations Division (Home).
Director of Plans Division.
Director of Air Division.
Deputy First Sea Lord.
Director of Operations Division (Foreign) and Administrative detail work.
Director of Intelligence Division.
Director of Training and Staff Duties.
Assistant Chief of Naval Staff.
Director of Trade Division.
Director of Mercantile Movements.
Director of Mine-sweeping.
Director of Anti-Submarine Division.
It will be seen that the alterations in Naval Staff organization were as follows: (a) The new Deputy First Sea Lord--Rear-Admiral Hope--who since the spring of 1917 had been Director of the Operations Division, was given the responsibility for operations in foreign waters, with a Director of Operations (foreign) under him, and was also definitely charged with the administrative detail involving technical matters.

The special gifts, experience and aptitude of this particular officer for such work enabled him, no doubt, to relieve the pressure on the First Sea Lord for administrative detail very materially.
(b) The Operations Division was separated into two parts (home and foreign), with a Director for each, instead of there being a Deputy Director for home and an Assistant Director for foreign work, both working under the Director.

This was a change in name only, as the same officer continued the foreign work under the new arrangement.
(c) The Director of the Intelligence Division and the Director of Training and Staff Duties were shown as working immediately under the First Sea Lord and Chief of the Naval Staff.
(d) A Director of the Air Division was introduced as a result of the Naval Air Service having been separated from the Admiralty and placed under the Air Ministry.

A larger Admiralty Staff organization for aerial matters thus became necessary, since the Staff could no longer refer to the Naval Air Service.
There were no other changes in the Staff organization.
