"Air Plane Carrier--Protected" ... January 31, 1923
Preliminary design plan for an aircraft carrier. This drawing
represents one of a series of alternative designs undertaken
to explore the capabilities possible in aircraft carriers ranging
from 10,000 to 29,250 tons in an attempt to select the best balance
between ship size and the number that could be built under the
Washington Treatys aggregate displacement limit. The calculations
supporting this 29,250 ton, "protected" design were
recorded in Preliminary Design Book V-3, which document probably
was discarded in the 1970s. An alternative 29,250 ton design
(Book V-2) had a two-level hangar.
This plan provides nine 8-inch guns, electric drive machinery,
and a speed of 27 knots in a ship 680 feet long on the waterline,
101 feet in beam on the waterline, and with a normal displacement
of 29,250 tons.
Note: The original document was ink on linen (black on
white).
The original plan is in the 1911-1925 "Spring Styles Book".
