Wessling, Germany – September 23, 2025 — Vaeridion GmbH and Deutsche Aircraft GmbH have signed a Memorandum of Understanding (MoU) to jointly explore technical and non-technical enablers in the field of R&T and development in furtherance of their leadership realizing sustainable regional aviation.

The collaboration brings together two companies with very different, yet best-in-class approaches in their respective field of operation and class.

VÆRIDION’s with its unique CS23 all-electric Microliner—a cost-effective, short-haul commuter aircraft for 9 passengers and Deutsche Aircraft, the D328 TC-holder and CS25 OEM, currently advancing the 40-seat D328eco®, a 100% SAF-ready regional aircraft.

Under the MoU, Deutsche Aircraft, the only Original Equipment Manufacturer (OEM) in Germany with full system integration capabilities, supports VÆRIDION in their pursuit of flight testing their advanced battery technology on the flying test bed UpLift D-CUPL from the German Aerospace Center (DLR).

Additionally, Deutsche Aircraft will contribute its expertise in structural design, industrialization and testing of new aircraft to the Microliner development.

This partnership aligns with both parties’ ongoing commitment to revitalizing local communities and underserved routes with the most innovative aviation solutions.

“This MoU marks a pivotal moment in our journey toward emission-free regional flights, ” said Markus Kochs-Kämper, CTO and Managing Director of VÆRIDION. “By uniting our technological expertise with Deutsche Aircraft’s long-standing engineering excellence and design quality, we aim to accelerate the Microliner programme and provide sustainable, cost-effective air travel solutions to underserved markets in Europe and beyond.”
