Wright R-1820-76A,B,C,D - 1,425 hp (1,063 kW) Cyclone 9 represented a further development of the Wright P-2 engine dating back to 1925. Featuring a greater displacement and a host of improvements, the R-1820 entered production in 1931. The engine remained in production well into the 1950s.

The Southern Cross is a C49J.  Delivered to the Army in 1942. Converted to a DC-3 in 1944 and used by the Department of Transportation up into the 1970s. During that time the engines were converted to 1820-76D making it one of the very few with 1475 hp on each wing.
