The perfect platform for high altitude reconnaissance and surveillance
Developed and Certified in 1991, the GROB G 520 is one of the world’s largest fully composite manned and unmanned aircraft, providing an ideal system platform for OPV/UAV applications (Optionally Piloted Vehicle).
The flexible payload-bay concept of the G 520 can accommodate multiple mission systems for both civilian and military applications and operations with a minimum of integration and modification lead time.
Based on its proven airframe and systems reliability the G 520 mitigates development risks for future UAV and/or system developments. The G 520 is the cost efficient performance platform for the UAV and OPV requirements of the 21st century, both in the HALE and MALE performance/application sector.
Full reconnaissance and surveillance capabilities.
The G 520 NG features:
- Long endurance, high altitude performance
- Short runway capabilities
- Reconfigurable payload installation
- Full approval for all-weather IFR/Icing operations acc. to LBA/FAA Part 23 regulations
12 payload compartments for up to 1000 kg of mission equipment makes the G 520 an ideal multi-role platform for a wide range of missions. Depending on payload the G 520 has a range up to 5000 km (2700 NM) or up to 11 Hrs (UAV 32 Hrs) on stage time in all weather conditions.
