In the spring of 1933, the Army Air Corps tested the prototype Curtiss T-32 "Condor II" twin engine biplane transport. The plane was quickly designed and produced to fill a need for a larger capacity commercial airliner. The Curtiss-Wright company hoped to sell the type before more advanced types being designed entered service (i.e. the Douglas DC-2).

During the early 1930s, the Army General Staff still believed that a large biplane was more reliable than a monoplane aircraft, so two T-32 transports were purchased with the designation YC-30. The plane featured a retractable landing gear operated by electric motors making it among the first transports with retractable landing gear. The YC-30 also had many access panels designed for easy and speedy ground maintenance tasks. The basic structure of the YC-30 was a steel and aluminum alloy framework and fabric covering.

The first YC-30 (S/N 33-320) was received by the Air Corps on May 12, 1933. Both planes were initially used as VIP transports and then as regular staff transports until withdrawn from service in 1938.
