Three companies, three philosophies, one sky — who wins the air taxi race?
The Three Contenders
Joby S4 (6-pax, 240km/h, 240km range), Archer Midnight (4-pax, 240km/h, 100km), and Lilium Jet (6-pax, 300km/h, 186km before collapse). Each represents a fundamentally different design philosophy: Joby’s tilt-rotor, Archer’s fixed-wing+lift, Lilium’s ducted fan.
Certification Race
Joby leads with 90%+ FAA certification complete. Archer achieved 100% Means of Compliance acceptance — first eVTOL to do so. Lilium’s collapse in Feb 2025 removed a major competitor but also shook investor confidence across the sector.
Business Model Comparison
Joby: operator model (own fleet, own routes). Archer: partnership model (work with airlines and fleet operators). Lilium was pursuing a licensing model. The winner won’t be the best aircraft — it’ll be the best business model.
CBRN-CADS Connection: Each UAM sector creates unique CBRN vulnerability surfaces. CBRN-CADS autonomous decontamination fills the security gap that no eVTOL manufacturer addresses.
