In the late 1980s, PZL started developing a new aircraft intended to combine high manoeuvrability, short take-off and landing (STOL) performance, and the ability to carry a 2,000 kg payload while remaining a low-cost platform to procure and to operate. Original designs for the aircraft revolved around a twin-turboprop engine. At one point, the Pratt & Whitney Canada PT6A-67A engine was selected to power the type. However, the proposal was radically changed following a decision to submit it to a requirement issued for Polish Air Force which sought a light strike and battlefield support aircraft; accordingly, the payload was doubled and the speed was raised dramatically. The revised design was instead powered by a pair of Pratt & Whitney Canada PW305 turbofan engines. Named the Skorpion, it featured a fuselage afterbody that was blended into the wing along with a set of small canards behind the cockpit.
According to aerospace publication Flight International, the origins of the Skorpion were within an earlier proposal for a twin-turboprop ground-attack aircraft. Reportedly, the Polish initiative had drawn some influence from a study performed by British Aerospace (BAE), known as the Small Agile Battlefield Aircraft, which was to be a relatively manoeuvrable, short take-off and landing (STOL) aircraft capable of carrying a 2,000 kg payload. Work commenced on the initiative at Warsaw-based aircraft manufacturer PZL Warszawa-Okecie during 1990. Early on, the company had several objectives for the aircraft, such as for it to be cheap and easy to construct, as well as to modify, the latter of which being accomplish via to its modular design. It also required an ability to take-off and land on a runway of about 250 m in length, travel at speeds of up to 640 km/h, be armed with a 25 mm cannon and be able to carry up to 2,000 kg of both Warsaw Pact and NATO munitions. Later versions were named 'D', and included a 'DT' training aircraft and a 'DB' combat variant.[]
Early on, the Pratt & Whitney Canada PT6A-67A turboprop engine was selected to power the type; these were to be mounted in a pusher configuration on either side of the rear fuselage. Reportedly, at this point in development, the majority of the proposed aircraft's technology was to be derived from PZL Okecie's earlier PZL-130 Orlik trainer aircraft. The company chose to submit its design to the Polish Air Force for a light strike and battlefield support aircraft..Ceiling
