Full Specifications

Do228 NXT: Versatile Twin-Turboprop STOL Aircraft

The Do228 NXT represents the next evolution of the proven Dornier 228 platform, a rugged twin-turboprop STOL (Short Takeoff and Landing) utility aircraft renowned for its reliability in demanding environments. With over 40 years of global operational heritage, the NXT variant incorporates modern avionics, optimized manufacturing, and enhanced capabilities while retaining the core design strengths that have made it a workhorse for military, government, and civilian operators. Its high-wing configuration, rectangular fuselage, and robust landing gear enable operations from short, unpaved runways, including grass and gravel strips, making it highly adaptable for remote and austere conditions.

Manufacturer

The Do228 NXT is manufactured by General Atomics AeroTec Systems (GA-ATS), a German subsidiary of the U.S.-based General Atomics, at its facility in Oberpfaffenhofen, Germany. GA-ATS acquired the program in 2021 from RUAG and has restarted series production with increased in-house manufacturing of key components like wings and control surfaces. The original design originated from Dornier GmbH in the early 1980s, with license production by Hindustan Aeronautics Limited (HAL) in India.

Speed and Range

Powered by two Honeywell TPE331-10 turboprop engines, the Do228 NXT achieves a maximum cruise speed of 240 KTAS (approximately 445 km/h) and offers outstanding range and endurance. Maximum range reaches about 1,340 NM (2,482 km) with zero payload, or around 1,323 NM with a typical 1,322 lb payload. Optional wet wing tanks extend endurance beyond 8–10 hours. It features excellent climb rates and service ceiling up to 25,000 ft, supporting efficient loiter and long-endurance missions.

Cost/Price

Exact pricing for the Do228 NXT varies by configuration and options (e.g., special mission equipment), but earlier NG variants were positioned around €5.2 million. The NXT benefits from low operating and maintenance costs, making it an economical choice compared to larger platforms for similar multi-role capabilities. Production is ramping up with plans for small-series output.

The aircraft excels in missions including maritime patrol, border surveillance, search and rescue, cargo/passenger transport (up to 19 seats), medevac, and paratrooper deployment. It supports flexible cabin configurations, four underwing hardpoints for sensors/pods, and modern glass cockpit features with electronic flight displays.
