Operational Context
PZL Świdnik SW-4 — light single-engine training helicopter
The SW-4 program was launched in the 1990s as Poland sought to develop a modern light helicopter for domestic and export use. The prototype first flew in 1996, and the type entered service in the early 2000s. It was designed for pilot training, liaison, and light transport missions.
Powered by a Rolls-Royce Allison 250-C20R turboshaft engine producing approximately 450 shaft horsepower, the SW-4 cruises at around 130 knots (240 km/h). Maximum takeoff weight is about 4,000 pounds (1,800 kg). The helicopter features a conventional main rotor and tail rotor configuration with a modern glass cockpit in later variants.
The SW-4 has been adopted by the Polish armed forces and civilian operators. An unmanned derivative has also been developed for experimental purposes. The aircraft marks an important step in Poland’s independent helicopter manufacturing capability.
