American defense technology
Autonomous airpower,
built the right way.
Falx Systems builds precise, uncrewed aerial systems for the United States and its allies. Designed, tested, and manufactured under flight test discipline.
The aircraft
FX-1. Heavy lift,
and hard to deny.
A heavy lift tactical multirotor built for contested environments. It flies for two hours, carries twenty kilograms, navigates without GPS, maps as it flies, and stays connected anywhere on earth over satellite and 5G.

The map it keeps.
Every flight becomes a permanent, centimeter-scale 3D map. Height colored, building by building, tree by tree. The FX-1 surveys as it flies and never forgets where it has been.
Resilience
Built to be
hard to break.
Most small aircraft fail the moment a single link fails. The FX-1 is designed with no single point of failure: five independent command paths, two independent navigation systems, and an airframe that keeps flying in the rain.
DRILL 01 · GPS DENIED
It keeps navigating.
Dual V-SLAM holds position and keeps mapping without a single satellite fix. The aircraft knows where it is because it remembers where it has been.
DRILL 02 · LINK JAMMED
Four more paths remain.
LEO and GEO satellite, 5G LTE, and encrypted 400 and 900 MHz telemetry with a dedicated backup receiver. Cutting one link changes nothing. Cutting all five at once is the hard problem, and it belongs to the other side.
DRILL 03 · WEATHER TURNS
It flies anyway.
Rainproof by airframe design. The mission continues while fair-weather aircraft wait on the ground.
DRILL 04 · HEAVY TASKING
It carries the load.
Twenty kilograms of payload and two hours on station. One aircraft does the work that would take a fleet of consumer platforms.
Where the category stops, the FX-1 continues.

Mission
Keep operators out of reach.
Keep America ahead.
Small, precise, uncrewed systems are rewriting the cost of air power. Our mission is to put that advantage in American and allied hands, with aircraft that are affordable enough to risk and disciplined enough to trust.
Precision autonomy
Software defined flight behavior, developed like flight software should be: logged, repeated, and signed, with a human accountable for every release.
American supply chain
Designed from inception for NDAA Section 848 compliance, engineered to Green UAS supply-chain and cybersecurity standards, and ITAR-aware at every layer. Allied supply chain by policy, not exception.
Operator first
One person carries it, launches it, and trusts it. Priced for attrition, built for the day the GPS and the links are gone.
Interactive
Fly the pattern.
The FX-1 maps as it flies and does not forget. Fly the survey: the terrain lights up where the aircraft has scanned, the map in the corner fills in, and each beacon you reach tells part of the story.

NEW RECORD
The name
The Dacian falx reached over the Roman shield wall and split what the shields were protecting. It is the only weapon that ever forced Rome to redesign its armor. Today the reaching weapons are uncrewed.

Questions
Falx Systems and the FX-1,
in plain terms.
What is Falx Systems?
Falx Systems is an American defense-technology company that builds autonomous uncrewed aerial systems (UAS) for the United States and its allies. Its first aircraft is the FX-1, a heavy-lift tactical multirotor. The company is a Delaware C-Corporation founded in 2026 by Kerem Isiktasli.
What is the FX-1?
The FX-1 is Falx Systems’ heavy-lift tactical uncrewed aerial system (UAS). It carries up to 20 kilograms, flies for roughly two hours, navigates without GPS using dual V-SLAM, maps as it flies, and stays connected anywhere over satellite and 5G.
How does the FX-1 fly without GPS?
The FX-1 uses dual V-SLAM (visual simultaneous localization and mapping) to hold position and keep mapping when satellite navigation is denied or jammed. It knows where it is because it remembers where it has been.
Who founded Falx Systems?
Falx Systems was founded by Kerem Isiktasli. It is a Delaware C-Corporation established in 2026 and based in Dover, Delaware, United States.
What makes the FX-1 different from a typical drone?
Where a typical small drone loses its mission the moment GPS or the control link fails, the FX-1 keeps navigating without GPS, holds multiple independent command paths, flies in the rain, and carries up to 20 kilograms for about two hours.
What is a heavy-lift UAS?
A heavy-lift UAS is an uncrewed aerial system built to carry substantial payloads. The FX-1 lifts up to 20 kilograms with a 40 kilogram maximum takeoff weight, well beyond consumer and prosumer multirotors.
Where is Falx Systems based?
Falx Systems, Inc. is incorporated in Delaware, United States, with its registered office in Dover, Delaware.
What is V-SLAM navigation?
V-SLAM, or visual simultaneous localization and mapping, is how the FX-1 navigates without GPS. Onboard cameras and computing build and continuously update a map of the environment, letting the aircraft know its position from what it sees rather than from a satellite fix.
Can the FX-1 fly beyond line of sight (BLOS)?
Yes. The FX-1 holds a beyond-line-of-sight command link over LEO and GEO satellite, so it can be operated far past the radio horizon, effectively anywhere on earth, in addition to 5G LTE and encrypted radio at closer range.
Is the FX-1 a Green UAS?
The FX-1 is engineered to Green UAS standards: an American-built airframe with an NDAA Section 848 aligned supply chain and cybersecurity designed in from the start. Falx Systems intends to pursue formal AUVSI Green UAS certification as the program matures, and the same discipline positions the aircraft for the Blue UAS pathway over time. Certification has not yet been granted.
Is Falx Systems hiring?
Yes. Falx Systems is a small crew with open roles in structures, flight software, and test operations. Some roles may require U.S.-person status under 22 CFR 120.62.
