The PZL-230F Skorpion was a compact aircraft – just 10 m long. It had a single pilot, twin jet engines,it was an advanced aircraft which was to use lightweight composite materials and fly-by-wire electronics. Yet at the same time the Skorpion was designed to be affordable, easy to build, well armoured for good survivability, and easy to adapt to a variety of roles.
It was also designed to be able to take-off and land on comparably short runways.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.
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.As of its 1994 redesign, performance estimates for the Skorpion included a maximum level speed of 540 kt (1,000 km/h), a 9,970 m (32,800 ft) service ceiling and a 300 km (160 nm) combat radius.In June 1994, the Polish Ministry of Defense announced that the Skorpion programme would receive no further funding from the government.
