Design

It is of classic semi-monocoque, metal structure with a slightly tapered wing. The pilot is accommodated in an enclosed, heated and ventilated cockpit with adjustable seats. The cockpit canopy slides backwards to open. The landing gear is non-retractable with a tail wheel. Rubber dampers provide shock absorption, and hydraulic brakes are used for wheel braking. The power plant comprises one 340 hp Textron Lycoming GSO-480-B1J6 piston engine and Hartzell HC-B3Z20-1/10151C-5 three-blade metal variable-pitch propeller. The engine cooling airflow is intensified by means of two specially designed ejectors. 36 US Gal of fuel contained in two rubber tanks enables a flight range of 350 NM for the fully armed configuration of the aircraft. 28 V DC electric power is supplied from a 1,5 kW generator and a storage battery. De-fogging and de-icing of the windshield is done by blowing of hot air.

Armament

Permanent armament comprises two wing-mounted 7.7 mm Colt–Browning Mk II machine guns with 650 rounds each and a collimator sight in the cockpit. For combat missions there is a capacity for an external load of bombs and two 57 mm and two 128 mm (HVAR-5) air-to-ground rocket launchers. Adapters on the underwing pylons can be used to switch the armament configuration from free-fall bombs to multi-tube launchers with twelve 57 mm air-to-ground rockets. Cluster or cargo bombs, or 128 mm air-to-ground rockets can be fitted.

Operation

The aircraft was specially designed for low-altitude missions against day and night visible ground targets in a broad area. It was readily available to be loaded with weapons and supplied through a flexible system of auxiliary airfields that required no special preparations, especially in mountainous regions. Yugoslav military planners assumed that potential aggressor will first disable airfields. Therefore, J-20 Kraguj was designed to take-off from short unprepared runways, even ones covered in deep snow when fitted with skis. It was also called a "Partisan aircraft". The Kraguj P-2 was intended for close ground force support, and could be used for training of pilots in visual day/night flights, aiming, missile firing and bombing of ground targets.
