Orbitalum

Orbitalum is a German micro-launcher startup founded in 2021 and based in Bremen, Lower Saxony, developing small liquid-propellant launch vehicles targeting the dedicated small satellite launch market in Europe — addressing the supply gap left by Ariane 6's focus on larger payloads and the suspension of Vega-C following its December 2022 launch failure.

Bremen is Germany's traditional aerospace hub, hosting Airbus Defence and Space facilities, OHB System AG, ArianeGroup structural manufacturing operations, and the DLR Institute of Space Systems — providing Orbitalum access to a dense regional aerospace engineering talent pool, test infrastructure, and institutional relationships for vehicle development and qualification. The proximity to Bremen's existing space industry ecosystem is a deliberate strategic choice for early-stage launch vehicle development.

Orbitalum's development program targets the small satellite rideshare and dedicated launch market where customers need precise orbital insertion to specific inclinations and altitudes not served by large rideshare missions, at price points below what Ariane 6 or Vega-C can offer for sub-100-kg payloads. The company competes conceptually with RFA (Rocket Factory Augsburg, also Bremen-based), ISAR Aerospace (Munich, with Norwegian launch site), and HyImpulse Technologies (Neuenstadt am Kocher) for European government and commercial small satellite launch contracts. Europe's push for sovereign small launch access following Vega-C's grounding and dependence on US rideshare creates an addressable market for multiple domestic micro-launcher companies.
