Accelerate Your Mission.

See how HEKA compresses the path from requirements to flight.

Field-Proven.
Flight-Ready.

HEKALink, HEKALegion, and VoltAI. One integrated stack.
Built to cut integration risk and compress time to flight.

The Status Quo.

Traditional aerospace missions run on disconnected tools, siloed teams, and manual processes. Cost and schedule risk compound at every phase.

Fragmented Digital Engineering

Critical lifecycle tools and teams are siloed, creating brittle hand-offs and lost time between CAD, simulation, controls, and software.

Slow, Costly Iteration

Validation and integration cycles stretch months or years. Schedule slip, cost growth, and repeated rework build from issues that could have been caught upstream.

Disconnected Path to Flight

Too many missions lose continuity from digital design to onboard software to deployed hardware, dropping critical context at every hand-off.

HEKA Closes That Gap.

Three integrated systems designed to work as one continuous platform.

HEKA HALO

The Whole Mission Stack.
One Source.

HEKA's family of modular, interoperable mission electronics — flight control, mission computing, navigation, RF, and vision engineered together.

Engineered Together.
Not Bolted Together.

Every Legion module runs HEKOS, HEKA's common safety-critical real-time OS, so updates, tooling, and behavior carry across the whole stack instead of requiring separate integrations for each box. Legion modules are natively integrated with HEKALink for design, simulation, and validation, and with VoltAI for power.

One Software Core

Every module runs HEKOS — updates and behavior carry across the whole stack instead of five separate integrations.

We Build It, Not Buy It

Every module originates from HEKA's own R&D. HEKA owns the roadmap rather than reselling third-party hardware.

Made in America

Designed and built domestically for an auditable, defensible supply chain with no foreign-sourcing surprises.

Modular & Scalable

Start with a single module and grow to the full stack without re-architecting the platform.

Aviation-Grade Safety

HEKOS targets DO-178C / DO-254, so certification evidence is built in from the start.

Simulates pitch, roll, yaw, and XYZ translation to validate control laws, GNC, and autonomy before hardware integration.

Virtual Wind Tunnel

Turns CAD models into lift, drag, and stability coefficients — no physical test article required.

Our Mission

Fly Sooner, Fly Faster

Most aerospace and defense missions still move through fragmented pipelines. CAD, simulation, controls, software, and hardware are separated by manual hand-offs, disconnected environments, and repeated rework. HEKA exists to fix that — with a reusable product and IP stack designed to compress development cycles from the start.

Our growth strategy is built on product sales, subscriptions, and licensing — not just engineering labor. Every engagement builds toward a faster, more reusable path for your next mission.
