A twin-engined Attack Bomber was produced in 1939 and was available for export as the NA-40 series. A single prototype was built.
The NA-40-1 NX14221 was first flown in January 1939 by Paul Balfour, powered by two 1100hp P&W R-1830. It was re-powered on factory model NA-40-2 with 1350hp Wright GR-2600.
