Isar Aerospace is a German launch vehicle company founded in March 2018 as a spin-off from the Technical University of Munich by Daniel Metzler, Josef Fleischmann, and Markus Brandl, based in Ottobrunn near Munich, aiming to give European satellite operators independent, flexible access to orbit.

Its two-stage Spectrum rocket is built with 3D-printed engines and carbon-composite structures to launch small and medium satellites and constellations through dedicated, lead, and rideshare missions, serving commercial and institutional satellite operators, backed by more than 400 employees from nearly 50 countries, and having completed its second orbital flight attempt in September 2026.
