Curtiss T-32 Condor / BT-32 / CT-32 Condor / R4C

Not to be confused with the Curtiss B-2 or its 18-passenger Condor airliner development, the Condor was a 15-passenger commercial biplane airliner of the early 1930s, powered by two 529-536.5kW Cyclone radial engines. It was produced in two versions: for normal daytime flying and as a convertible day- and night-sleeper transport with six compartments, each accommodating two berths/seats.
In 1933 American Airlines began flying the 18 seat Curtis Condor, the first US sleeper plane.
One was used on the Byrd Antarctic Expedition and two were operated by the US Navy as R4C. An all-cargo version was produced as the CT-32.
As a military heavy bomber with troop-carrying and ambulance capability, the Condor was supplied to China. Armament comprised five 7.62mm machine-guns and up to 1,800kg of bombs.
