North American won with its NA-300 design a competition for a light armed reconnaissance aircraft (LARA), destined for the US Air Force, Army and Navy. The OV-10 Bronco as it is called is quite an unsual design with its twin tail booms that both have a swept vertical stabiliser with a horizontal stabiliser in between, in T-tail configuration. At the front of the tail booms, just below and in front of the wings is a turboprop engine with air intake above the propeller spinner. The exhausts are at the side of the nacelles, underneath the wings. These wings have a relatively short span. The fuselage with tandem cockpit 'hangs' from the wings, in between the tail booms. The canopy is flush with the top of the fuselage and wings. Several pylons can be attached to the lower side of the fuselage and underneath it. The Bronco has an all single wheel retractable gear, of which the long main gears retract rearward in the tail booms.

The different versions of the OV-10 Bronco can externally be distinguished by amongst others

• the presence of an HF wire antenna between the rear fuselage and horizontal stabiliser
• whether the rear of the fuselage has a clear dome or not
• the presence of a jet engine on top of the fuselage
• the number of propeller blades
• the shape of the nose

More details will follow later.
