My dear Mr. Secretary:
 
     It is importent that we know on Monday the number
of airplanes by types that can be exported from the 
United States each month beginning October 1 through 
July 1, 1942. I want this figure irrespective of the 
source of funds.
 
     As a rule of thumbw particularly as it concerns
the 4-engine heavy bomber, I suggest 50 percent of our 
output from January 1 to July 1, meeting the commitment 
until January 1 which General Marshall and General 
Arnold worked out with the British at my conference 
with Churchill.
 
     The planes which the British promised the Russians 
on a monthly basis will be fighter planes, probably 
Hurricanes.
 
                         Very sincerely yours,
                                   (Signed) FDR
The Honorable
          The Secretary of War.
