Developing Valo, an eight-EPU eVTOL progressing through a UK CAA-led certification program with EASA co-operation; Vertical now expects Type Certification in 2029 after re-baselining the prior 2028 target.
Propulsion Architecture
Eight electric propulsion units (EPUs), each with multiple electrically isolated power lanes; eight liquid-cooled underfloor battery packs; redesigned wing/propeller architecture succeeding the earlier VX4 tilt-rotor layout.
Primary Certification Context
EASA / UK CAA SC-VTOL
Strengths
Vertical has progressed three full-scale prototypes through a piloted flight-test campaign and is using that evidence to mature the Valo design toward Critical Design Review. The company’s certification strategy is UK CAA-led with EASA co-operation under the SC-VTOL framework.
Primary evidence: Vertical H1 2026 SEC-filed business update; Valo configuration release.
Weaknesses / Open Questions
Vertical’s August 2026 SEC-filed H1 materials re-baselined the earlier 2028 certification target to 2029. That remains company guidance rather than a regulator-committed date. Critical Design Review, certification-conforming aircraft, compliance demonstration, production approval and operating approvals remain ahead.
