THE JAPANESE FORCES 
By mid-1944, the Imperial Japanese Navy (IJN) 
was in dire trouble, dangerously short of
 aircraft 
and fuel. In contrast, by fall 1944 the US Navy 
had mushroomed. Aircraft carriers had emerged 
as queens of the board and air superiority had 
become essential, not only for victory but also 
for sheer survival. The best area that the 
Japanese fleet could hope to defend was one 
bounded by a line from Japan to the Ryukyus, 
thence to Formosa and the Philippines, as there 
would be limited air cover provided from land-
based aircrews. To counter an assault on various 
points of
 this
 periphery, the Japanese developed 
four so-called SHO plans, all relying on
 effective 
integration between naval forces and land-
based air power. 
Although reduced by nearly three years of 
war, the Japanese fleet remained formidable. 
It could still muster seven battleships, 11 
carriers, 13 heavy, and seven light cruisers. 
Destroyers, so essential to any operation, had 
been reduced from 151 to just 63, while only 49 
submarines remained. 
Superficial comparison with Halsey's 3rd 
Fleet might lead
 to
 an assumption that a "decisive 
battle" was not out of the question, for the 
American admiral's strength stood at seven 
battleships, eight attack, and eight light carriers, 
eight heavy, and nine light cruisers. Halsey, 
however, was concentrated where his opponents 
were not. Halsey's ships were all modern, all 
well-trained, and could, to an extent, be replaced. 
He also had Kinkaid's 7th Fleet as back-up. 
Japanese ships were of varying vintage and 
their radar and communications much inferior 
to those of the Americans (although, as events 
were to show, equipment is only as good as 
those using it). The crucial factor, however, 
was that between them, the 3rd Fleet's carriers 
could muster 800 or more aircraft. 
OPPOSING PLANS 
THE US PLAN 
The proposed landings in Leyte Gulf involved 
two beaches. Designated Northern and 
Southern, each was about three miles in 
length, and about 11 miles wide, with two 
attack forces assigned to each. 
The major purpose of the landings, as 
envisaged by the Joint Chiefs of Staff was 
effectively to separate Japanese forces based in 
the major islands of Luzon in the north and 
Mindanao in the south. This would permit the 
establishment of a springboard from which 
the strategically essential island of Luzon could 
be taken, while containing and by-passing the 
non-essential territory of Mindanao. 
MacArthur controlled not only the strike 
capacity of the 7th Fleet's considerable force of 
escort carriers but Army Air Forces Southwest 
Pacific. To complicate matters, there were two 
further army air commands in the theater - XIV 
and XX Army Air Forces - while there was also 
the British Pacific Fleet. The latter staged a 
major diversion in the Indian Ocean but the 
Japanese were not fooled. 
JAPANESE PLAN 
The IJN knew that it would have to await 
trained replacements before being able to 
engage the US Navy in the "decisive battle" 
that doctrine demanded. The pace of the 
Allied advance, however, meant that the 
desperately required breathing space would 
not be granted to them. All pointers indicated 
that the Philippines would be the next 
objective and that, of the four variations on 
the SHO-GO contingency plan, SHO-i would 
be the one most likely to be implemented. 
It would have to be pursued with what forces 
were to hand.
