Pre-Prototype · Systems in Design Phase

Lean UAV systems for an asymmetric era

Complete unmanned aircraft systems for government and institutional operators — designed in Türkiye.

We build the airframes, avionics, and ground systems behind each platform. Our combat systems are built to be expendable: low cost, fast to produce, modular by design. ISR variants, subsystem supply, and consulting work follow the same lean discipline without that constraint.

About

Why we're called Hendek

Hendek means "trench" in Turkish, and the name points to the Battle of the Trench — where an outnumbered defender held a stronger force at bay by digging a trench instead of meeting it head-on. Asymmetric, low-cost, and effective. That is the engineering approach behind this company.

We are a lean, Türkiye-based UAV manufacturer building complete systems for government and institutional operators. Because our combat systems are expendable, we design for low cost, fast production, and modularity — and we spend engineering effort only where a specific requirement justifies it. Over-engineering is treated as a defect, not a virtue.

That same discipline carries into rapid prototyping: we iterate designs with 3D printing before committing to tooling or composite layup, so a design earns its production method rather than defaulting to one.

Hendek is pre-prototype and seed-stage today. Every system on this site is shown with its current development status — we'd rather be precise about where we are than oversell where we're going.

Complete UAV Platforms

Two tiers, built around a shared design philosophy: every airframe earns its construction method, and every system states its real development stage.

Tactical Tier — Delta-Wing OWA & ISR

Design Stage

OWA (one-way attack) and ISR (intelligence, surveillance, reconnaissance) payloads share the same airframe here: a delta-wing pusher configuration with twin-piston engines driving a single pusher propeller through a common gearbox and shaft. Non-modular carbon/glass-fibre structure, sized for production speed and cost rather than maximum range.

ConfigurationDelta-wing, twin-piston pusher
Wingspan~2.5 m
Cruise Speed~150 km/h
MTOW60 kg
Payload15 kg, swappable OWA & ISR payload
Range250 km
StructureCarbon / glass fibre, non-modular
Launch

Our own launcher is the primary system offering. A vehicle-mounted (car-launched) thrower design is already complete and ready for the next stage; rocket-assisted, catapult, and rail options remain in development. The platform is also designed to be launcher-agnostic as a secondary capability.

Small Tier — Electric, Dual-Role

Two variants share a common backbone and differ only in airframe construction. Both accept either a strike payload (OWA) or an ISR sensor package in the same nose/payload bay, so one platform serves two missions.

Modular Construction

Modular Variant

Fast and inexpensive to manufacture, built for high-volume expendable use. A common fuselage accepts three interchangeable module sets — range, endurance, or speed — so one production line covers three mission profiles.

Efficiency Variant

Carbon and glass fibre construction for missions where range or endurance justifies a higher unit cost. Same backbone and dual-role payload bay as the modular variant, built to a higher performance ceiling.

Beyond Complete Systems

Two service lines that put our existing manufacturing and engineering capacity to work between government programmes.

B2B — Airframe Subsystems

Airframe & Structures Supply

We design and manufacture UAV airframes and structural components for third-party UAV companies that need reliable production capacity without building it in-house. At least one prospective client is already engaged.

  • Carbon & glass fibre airframes
  • Wing and tail assemblies
  • Custom structural components
  • 3D-printed structural parts
  • Small-batch & serial production
Engineering Consulting

Systems & Aeronautical Consulting

Clearly scoped systems-level and aeronautical engineering consulting with defined deliverables — not open-ended advisory work — so engagements stay focused and your IP stays protected.

  • Full aircraft / UAV design
  • UAV system architecture & requirements
  • Airframe structural analysis
  • Propulsion system selection & sizing
  • Composite manufacturing process design
  • Rapid prototyping strategy
Manufacturing

How We Build

Production methods are chosen per design, not assumed in advance.

CF / GF Composite

Carbon and glass fibre layup for platforms where performance, range, or structural loading justify the added cost — the Efficiency variant and the Tactical Tier.

Low-Cost Modular Construction

Fast, inexpensive airframe construction for the high-volume Modular variant, built to be produced and replaced at expendable-system cost.

3D-Printed Prototyping

A cross-cutting R&D capability, not a standalone product line — used to iterate every design quickly before it earns its production method.
