Operational Context

Sino Swearingen SJ30-2 — high-speed light business jet

The SJ30 originated in the 1980s under Ed Swearingen’s vision for a compact but fast business jet. After multiple ownership changes and delays, the SJ30-2 variant entered service in the 2000s. The design emphasizes aerodynamic efficiency and a relatively high cruise speed for a light jet.

Powered by two Williams FJ44 turbofan engines producing approximately 2,300 pounds of thrust (10 kN) each, the SJ30-2 cruises at around 450 knots (830 km/h). Maximum takeoff weight is roughly 13,950 pounds (6,330 kg). Range approaches 2,500 nautical miles (4,630 km) depending on configuration.

The aircraft’s high cruise speed and long range distinguish it within the light jet segment. Production volumes have remained modest compared with larger manufacturers. The SJ30-2 stands as a technically ambitious design within business aviation.
