Deep Blue Aerospace

Deep Blue Aerospace (深蓝航天, Shenlanhangtiān), founded in 2016 and headquartered in Beijing, is a Chinese private launch company developing reusable liquid-propellant rockets for commercial small satellite and rideshare missions, most notable for becoming one of the first Chinese companies to demonstrate controlled vertical takeoff and landing (VTOL) rocket recovery — a key enabling technology for economically reusable boosters.

Deep Blue's Nebula-1 (星云一号) is a small-lift liquid-oxygen/kerosene rocket with approximately 500 kg payload to low Earth orbit. The company conducted a series of sub-orbital VTVL (vertical takeoff, vertical landing) hop tests with the Nebula-M test vehicle between 2021 and 2023, achieving kilometer-class altitude hops with successful propulsive landings — demonstrating the guidance, navigation, and control software needed for first-stage recovery. These tests placed Deep Blue alongside Space Pioneer (Tianlong) and Landspace (Zhuque-2) as frontrunners in China's commercial launch reusability race.

Deep Blue Aerospace's technical team includes engineers with backgrounds from CASC and CASIC, leveraging China's state aerospace industry expertise in a venture-backed commercial structure. The company has raised funding from prominent Chinese venture capital and industrial investors supporting the commercial space sector.

The Chinese commercial launch market has grown rapidly since the 2015 regulatory opening that permitted private companies to build orbital rockets. Deep Blue competes with iSpace (Hyperbola-1, first Chinese private orbital rocket 2019), Galactic Energy (Ceres-1 operational), Orienspace, and Spacety. Internationally, it positions against RocketLab and ISRO PSLV for Asian rideshare customers seeking sovereign Chinese launch alternatives.
