Ligh-T 4
ElistairThe Ligh-T 4 is a compact, man-portable tethered drone ground station manufactured by Elistair (Dardilly, France), designed to provide unlimited-endurance aerial surveillance by supplying continuous power via a 70-meter kevlar-reinforced micro-tether to compatible multirotor drones (DJI M300/M350/M30 and others). It delivers up to 1800 W peak power, weighs 20 kg, and can be deployed in under 5 minutes, making it suited for first responders, law enforcement, border surveillance, and event security. The system is a tether station only — it does not include a drone — and requires a human pilot to operate the attached drone; autonomy is limited to the drone platform chosen, not the tether station itself. With 1000+ units deployed across 60+ countries and 50,000+ hours of overwatch logged, it is a well-established product in the tethered UAS market. All available evidence is vendor/official/commerce-sourced; no independent teardown or third-party critical review was identified.

Evidence-graded claims from the Elistair deep report
Khronos DroneBox is a fully automated system: push-button operation, automatic takeoff and landing, airborne in under 2 minutes, 24-hour uninterrupted continuous flight, with full failsafe — operator only needs to monitor surveillance output.
All automation claims originate exclusively from Elistair's own product pages and press releases [3][13]; no independent teardown, third-party operational review, or customer report is present in the dossier to corroborate the claimed autonomy level.
from Elistair deep report →Elistair has deployed 2,000+ units to 600+ customers across 70+ countries, enabling 200,000+ hours of overwatch.
These deployment figures are repeated consistently across Elistair's own official and commerce pages [1][6][12], but no independent audit, third-party market report, or customer verification is present in the dossier to substantiate the specific numbers.
from Elistair deep report →The Orion 2 military persistent drone achieved a 50-hour continuous flight record, and Elistair holds a DGA (French Armament General Directorate) framework agreement for the Orion 2.
Both the 50-hour flight record and the DGA framework agreement are sourced from Elistair's own news releases [11][12]; no independent DGA confirmation, official procurement notice, or third-party reporting is present in the dossier.
from Elistair deep report →Elistair secured a €3M contract with an allied military force and supplied 13 drones to Terra Spatium (Greece), demonstrating real-world military deployment at scale beyond pilot programs.
Both contracts are cited in Elistair's own news releases [11][12]; the allied military customer is unnamed, and no independent procurement record, customer statement, or third-party reporting corroborates either deal.
from Elistair deep report →The Safe-T 2 tethering station delivers up to 2,500W peak power via a 110m micro-tether, is IEC 62368 certified, CE and NDAA compliant, and supports DJI M400/M350, FLIR SkyRaider, and other 6S/8S/12S drones.
All specifications and compliance claims are drawn from Elistair's official product pages [4][7]; IEC/CE/NDAA certifications are plausible and self-reported, but no independent certification body confirmation or third-party test data appears in the dossier.
from Elistair deep report →Elistair raised a €5M Series B from Omnes and Starquest Capital (announced 2021), representing the company's most recent disclosed funding round.
The €5M Series B is confirmed in Elistair's own news release [9][10]; no independent financial press coverage or investor confirmation appears in the dossier, and no subsequent funding rounds are documented, leaving the current financial position unverified.
from Elistair deep report →
Khronos can be deployed vehicle-mounted with a follow-me function, allowing operators to remain inside the vehicle during operation — enabling mobile persistent ISR without dismounting.
Vehicle-mounted and follow-me capabilities are claimed on Elistair's official product page [3], but no independent field demonstration, military exercise report, or third-party video/review in the dossier confirms this capability has been operationally validated — and the ORION 2026 exercise mention is also vendor-sourced only.
