ST-Flex Guardian Class
The world’s most advanced rapidly deployable autonomous aerostat
ST-Flex Guardian Class outperforms traditional aerostats and tethered drones
Rapid Deployment
The towable ST-Flex
System can be deployed
by a small team in
less than a day
Simplified Operations
Aerostat Autopilot eliminates the
need for an on-site crew. Multiple
sites can be monitored from a
single ops center
Increased Uptime
Advanced stability control and
updraft/downdraft protection
allow ST-Flex to fly through
high winds and rough weather

Deployment
All components of ST-Flex are housed on two
highway-towable trailers. Once on site, a small team can deploy the mooring station, inflate the aerostat, and complete commissioning steps to begin operations.
All set up operations are designed to be completed
with 4 people in less than a day.
Need to move your ST-Flex? Pack up can also be
completed in less than a day with a team of the same
size.
Payload
ST-Flex is built with a modular payload bay capable of accommodating a wide range of technologies including radar, EO/IR Sensors, comms relays, and more.
The quick connect rail system allows for fast
in-field equipment swaps.
The payload access work platform provides easy access
to rapidly install, maintain, and switch key equipment
without additional site infrastructure.
Operations
With Aerostat Autopilot, a single operator can simply
send a launch command to the ST-Flex and the
aerostat will autonomously take-off and fly.
Launching and landing can be done autonomously
without need for an on-site crew.
Local and remote control are both available for operators as their mission requires.
ST-Flex Guardian Class Aerostats Modernize Over a Century of Aerostat History
Aerostats are a proven battle-hardened aerial platform valued by militaries and governments
around the world for their safety, resiliency and flexibility with decades
of successful field operations in harsh conditions.
ST-Flex equipped with Aerostat Autopilot brings aerostats into the modern age with
cutting edge autonomy and unmatched mission availability
