The Independences
were completed in 1943. They
were an emergency measure, Cleveland-class
light cruiser
hulls converted to smaller fleet
aircraft carriers. The driving force behind their conversion was Roosevelt himself,
who
ignored the protests of his naval architects that the fine lines
of the
cruiser hulls would preclude a roomy hangar and large island and
make
it difficult to position the elevators or support the forward
flight
deck. A compromise design was developed that truncated the flight
deck,
included a very small island resembling those of escort carriers,
made do with
a rather small hangar, and bulged the hull to maintain stability.
This
required some modifications to the belt armor. Class A armor could
not
be easily welded to the blister frame, and class B armor could not
be
provided in time for the first two ships, which were completed
with no
belts to speed their
delivery to the fleet. The blisters were designed only for
stability
and the ships lacked any meaningful underwater protection.
The air group was typically 12 F6F Hellcat fighters, 9 TBM Avenger torpedo bombers, and 9
SBD Dauntless dive bombers, but in
practice
many more aircraft could be carried, if not efficiently operated.
As it turned out, they began entering
service at
almost exactly the same time as the Essexes,
which meant they never really played a crucial role in the war,
being
overshadowed by their larger and more capable sisters. They
had an
unusually hefty armor belt but
were
unable to operate large air groups
and
lacked the impressive 5"/38
batteries of the
larger carriers. By the end of the war they were being employed as
aircraft transports,
carrying up to 40 aircraft in their hangars and another 60 to 70
on
their flight decks.
Independence
herself completed with two 5"/38
DP
guns in place of the two quad 40mm guns.
