SCALES OF ATTACK.
 
              (a) NAVAL. Close escort, to protect convoys and subsequen'6i?;cover each laladinc, iiight consist of'- 6 Cruisers, ~2 Aircraft Carriers and possibly 2 Seaplane Carriers, 20 Destroyers.
 
             Y, ain Jaoanese Im~eet would be disoosed so as to intercept any large scale interference by iYl!ies.
 
(b) I;iILITARY. Some 1'2 Jaoanese Divisions
could be made ~avaiiafo!~ and t,_a~ s~ort
                                                     :~          for operations
against Australia and !{ew Zealand, and fo!lowiiag might be scales of attack in each phase'-
 
              (i) Darwin. Attac:- on Darwin likely to be ziade by one to two divisions transported in
                   ~t and s~ual! craft    initial l~ndznos
landing cra~,                                     .                   ~ x
carried out by Brigade groups.
 
            (ii) Australia. G or 7 divisions likely to make attack oia continent of Australia, landing up to 2 d~visions at 2 or niore .,~ points simultalleousl7. Initial landings '~;ould be carried out by Bi-igade groups in landing craft transported to asse~Joly positions in , landing craft carriers.
 
          (iii) Nevz Zealand. From 4 to 5 divisions would make attack similar to (ii) above.
 
                If attacks on Australia and :;Tew Zealand
      not simultaneous, scale of attaci~ against
      either could be increased acco~,zno!~. ~vail-
   ' ability of special landinzcraft would not be
z limiting factor for any of above operations.
      Large n,~b~ibers of small craft such as Pearling
      Luggers small Trading schooners available in
      Caroline islands which could be used for this
      purp o s e.
 
              (c) AIR. Following scales of attack based on as svn:lvt ion ~i~at no developments'n~d~ occ'arrea' on Russian front which ,rould justify Japanese reducing Air Force retained to meet potential tlmreats in that theater of war.
 
(i) To cover landing and obta n aero-
dromes from -~-'
               ~zch to develop operations on
shore, Japanese ~:light support landings with Some 5 or 6 aircraft carriers, and similar n'muber of seaplane carriers, capable of carrying some 250 aircraft, coriprising say 100 figliters and 150 dive and torpedo bo,-Ibors and up to 100 seaplanes.
 
(ii) As soon as port captured, Japanese
could bring, by ships and possibly overland fror, i
Darwin a~ea, if intermediate landing groum_ds _,~d
been established, additional !an~ based aircraft.
Ass ....~ ~
~,-~,o operations in I~.alaya and Phzlippines
successfully concluded, they might make available
some 400 of such aircraft and possibly in addition
some 30 long range flying boats.
