In 1938 the Air Corps bought a single DC-2 type aircraft. The plane, designated C-41, was very similar to the C-39 with only a few differences. The C-41 was powered by two Pratt & Whitney R-1830 radial engines with 1,200 hp each. The upgraded engines were more powerful than the 975-hp Wright radials of the C-39 and gave the C-41 a top speed of 225 mph -- 15 mph faster than the C-39. The cruising speed of the C-41 was nearly 50 mph faster than the C-39.

The other significant difference between the two types was the interior. The C-41 was bought as a senior staff transport, so the cabin was finished to allow in-flight staff work and meetings in addition to being more luxurious than the standard troop transport.

The C-41 was used by Gen. Henry H. "Hap" Arnold, Army Air Corps Chief of Staff, beginning in 1939.
