Oro Bay Airfield (also known as Cape Sudest Airfield) is a former World War II airfield in Oro Province, Papua New Guinea. The airfield was abandoned after the war and today is almost totally returned to its natural state.
Oro Bay Airfield was primarily an emergency landing field, although it was briefly used as a headquarters base for the 308th Bombardment Wing (1 February-2 July 1944) and as an operational airfield for the 417th Bombardment Group (28 January-4 February 1944) which flew A-20 Havocs. Operational squadrons assigned to the airfield were:
In addition, the 547th Night Fighter Squadron flew a night fighter variant of the P-38 Lightning and P-61 Black Widow from the airfield (5 September-6 October 1944).
