Cumulus
60 m hybrid heavy-lift airship — 10 t outsized cargo, 1,400 km range, vertical load and unload where no runway exists. Pacific Logistics Corridor.
Overview
We don't fly aircraft. We deploy airspace.
Segal Aeronautics designs and builds autonomous aerial platforms across four theaters of the air — logistics, intelligence, transportation, and the stratosphere. One airframe architecture, one autonomy stack, re-skinned to become a freighter, a sensor, or a seat.
Every airframe is surveyed, modeled, fabricated, launched, and operated as one continuous system. The spine is Vector, the autonomy stack: a Segal airframe resolves its own airspace, holds station without a cockpit crew, and reports its condition rib by rib.
Four programs carry the thesis — Segal Lift (heavy-lift airships, cargo VTOL), Segal Vigil (persistent ISR), Segal Transit (regional eVTOL), and Segal Apex (high-altitude platforms) — sharing one operations picture with the Segal naval fleet, seabed to stratosphere.

Capabilities
LIFT
Heavy-Lift Airships
Hybrid buoyant + vectored-electric envelopes lifting outsized cargo into austere fields — corridor-keeping, hover-discharge, no runway, no flight crew.
VTOL
Autonomous Cargo VTOL
Distributed-electric multirotor freight for mid-mile resupply — palletized modules, engine-out redundancy, charge-and-redispatch from a standard vertipad.
CONTROLLED
Persistent ISR / HALE
High-altitude long-endurance fixed-wing holding a surveillance box for 120h+ with EO/IR, SAR, and SIGINT-class masts. Controlled payloads gated by eligibility.
AEROSTAT
Tethered Aerostats
Rapid-deploy overwatch — a helium aerostat carrying a stabilized EO/IR ball, powered and datalinked up the tether, mast-up in under an hour.
eVTOL
Regional eVTOL
Quiet distributed-electric tilt-rotors moving passengers and priority cargo vertiport-to-vertiport — 250 km electric range at city and regional scale.
HAPS
High-Altitude Platforms
Solar-electric pseudo-satellites stationing at 20 km for weeks to months — comms backhaul, wide-area persistent sensing, the ground-to-orbit handoff.
LIVE
Vector Autonomy Stack
Detect-and-avoid, dynamic positioning, hover-and-discharge — certified to fly crewless on a standard sortie. Shared spine with the naval fleet's Helm.
BETA
Hangar Configurator
Spec and order an airframe from a live model — span, lift system, payload, module loadout — against a real-time constraint engine with a delivery window.
Case Studies
Porter
Autonomous cargo VTOL — 1.5 t palletized, 400 km corridor, hover-discharge. Eight lift rotors, engine-out redundant. Island Resupply Network.
Vantage
HALE ISR drone — 120h+ endurance at 19 km, modular EO/IR, SAR, and SIGINT mast, edge-fused protected downlink. Eligibility required.
Tether
Rapid-deploy tethered aerostat — persistent EO/IR overwatch from 1,500 m, 15-day standard station, power and fibre up the tether.
Meridian
4-seat regional eVTOL — 250 km electric, low acoustic signature, vertiport-native turnaround. Certification campaign underway.
Apex
Solar HAPS — 78 m wing holding the stratosphere at 20 km for 30 to 90 days. Comms relay, persistent sensing, the handoff to the Segal space arm.
