First Dirt Operation for Mojave STOL UAS

General Atomics Aeronautical Systems, Inc. (GA-ASI) has completed multiple successful take-offs and landings with its Mojave UAS on a dirt strip near El Mirage, California.

According to GA-ASI, the flight tests were the first-ever Short Takeoff and Landing (STOL) on a dirt surface for Mojave, with take-offs performed in as little as 586 feet; and short landings completed in as little as 335 feet.

The tests were primarily focused on gathering terrain feedback using Mojave, not achieving the shortest distances possible.

The ability to take off and land on unimproved surfaces demonstrates Mojave’s departure from traditional fixed-wing aircraft’s dependence on prepared runways. 

This new capability is said to provide greater versatility and allows the aircraft to operate in areas previously deemed unsuitable for UAS operations.

“Being able to execute missions in austere locations with runway independence opens the operational envelope for commanders across all services and geographic locations,” said GA-ASI President David R. Alexander. “Mojave can do this while retaining significant advantages in endurance and persistence over Vertical Takeoff and Landing (VTOL) and manned aircraft.”

Tracing its lineage from the MQ-1C Gray Eagle and MQ-9 Reaper, Mojave is a technical demonstrator with STOL capability, making it a versatile expeditionary UAS.

Adhering to Modular Open System Approach (MOSA) principles, Mojave leverages the modernized avionics, data links, sensor integration, and laptop ground control station of GA-ASI’s Gray Eagle 25M program. These features, along with Mojave’s enlarged wings with high-lift devices, combat-proven 450-HP turbine engine, and ruggedized landing gear, are thought to make it ideal for semi-improved surfaces with a small ground support footprint.  

Mojave provides options for forward-basing operations without the need for typical airport runways or infrastructure, so it can be rapidly deployed from and recovered to non-traditional discrete locations. To extend operational reach, Mojave can fit into a C-130 and be rapidly assembled and employed. These innovations make Mojave the perfect UAS to perform Reconnaissance, Surveillance, and Target Acquisition (RSTA), attack, and contested logistics support missions.
