Operation Mo
Encyclopedia
Operation Mo or the Port Moresby Operation was the name of the Japanese
plan to take control of the Australian Territory of New Guinea
during World War II
as well as other locations in the South Pacific
with the goal of isolating Australia and New Zealand from their ally
the United States. The plan was developed by the Imperial Japanese Navy
and supported by Admiral Isoroku Yamamoto
, the commander-in-chief of the Combined Fleet. The operation failed.
(air strikes against Lae
and Salamaua
, disembarkation in Huon Gulf
, New Britain (Rabaul
), New Ireland (Kavieng
), Finch Harbor (also called Finschhafen), and the capture of Morobe
and Buna
), it envisioned those territories as support points to implement the capture of Port Moresby
. The implementation of these operations was assigned to the Japanese Naval task force led by Admiral
Chūichi Nagumo
, after completing the Java
campaign. Another important step was the occupation of Christmas Island
to the south of Java. The Japanese Navy General Staff had been considering Operation Mo since 1938, as a step in the consolidation of the Southern Seas areas in the Greater East Asia Co-Prosperity Sphere
(大東亜共栄圏 Dai-tō-a Kyōeiken).
In April 1942, the operation was organized into four large actions and was approved by the Army and Navy General Staffs:
.
Japanese naval intelligence also suspected the presence of the American aircraft carrier
in Coral Sea
waters during this period.
The Port Moresby occupation force was composed of the following units:
Supporting these operations and intercepting any Allied interference, Rear Admiral Aritomo Goto
commanded:
During the course of operation, Yamamoto
sent the following heavy support force from Truk, led by Rear Admiral Chuichi Hara
:
Supporting this force was the 25th Air Fleet, (Yokohama Air Corps) led by Rear Admiral Sadayoshi Yamada

"Pete" reconnaissance seaplanes. This unit bombed Port Moresby
on 5–6 May, ahead of the Japanese Army-Navy landing on 7 May.
set sail southward from Rabaul
for Port Moresby
. This same day US aircraft from Yorktown attacked the Tulagi assault force, inflicting heavy damage, but were unsuccessful in preventing the occupation of Tulagi, Gavutu, and Tanambogo islands. Three days later, as a naval engagement appeared to be brewing in the Coral Sea
, the Japanese Moresby transports immediately veered back to the north, in order to avoid combat. The resulting Battle of the Coral Sea
inflicted significant aircraft losses on the Fourth Fleet
, Shōhō was sunk, and Shōkaku was damaged.
The Japanese abandoned their plans to land the South Seas Detachment directly at Port Moresby from the sea. The Japanese Army was making new preparations for combat when, on 11 July, High Command ordered the suspension of the projected actions against New Caledonia
, Fiji
, and Samoa
, because the Combined Fleet
was defeated at Midway
.
These battles prevented the Japanese landings against Port Moresby. Instead the Japanese army commenced an ultimately unsuccessful campaign to take Port Moresby with an overland approach across the Owen Stanley Range
via the Kokoda Track
