New Medium-Lift Rocket Unveiled as Industry Executives Warn of Looming Launch Capacity Crunch

A new aerospace startup has entered the medium-lift market with plans for a methane-fueled rocket, while industry executives and government officials confront mounting concerns over national security demand, launch supply limits, and evolving strategies across the commercial space sector.

Cowboy Space Unveils 'Big Iron'

Startup Cowboy Space revealed specifications for its proposed medium-lift launch vehicle, named Big Iron. Founded by billionaire Robinhood co-founder Baiju Bhatt, the company plans to target the emerging market for space-based artificial intelligence. According to details reported by Aviation Week & Space Technology, the rocket is designed to stand 282 feet tall and approximately 15 feet in diameter, utilizing nine methane-fueled Clydesdale engines on the first stage and a single engine on the upper stage.

The vehicle is projected to carry up to 18 metric tons to low-Earth orbit. Notably, the upper stage is designed to function as an orbital data center spacecraft featuring five GPU racks and inter-satellite laser links. Industry observers note that while the concept is ambitious, the company currently has limited hardware to show for the reveal and lags behind other providers nearing launch pad milestones.

Launch Market Pressures and Government Strategy

During the Silicon Valley Space Week conference, aerospace executives warned that the U.S. government may have overestimated the commercial launch market's current capacity to support growing military needs. Representatives from companies including Stoke Space and United Launch Alliance pointed to potential bottlenecks as national security demands rise and SpaceX transitions its focus toward next-generation vehicles and internal computing infrastructure.

Meanwhile, the Pentagon's Office of Strategic Capital issued a conditional $150 million loan commitment to Stoke Space to help construct a second launch pad at Cape Canaveral Space Force Station. The loan is subject to ongoing due diligence requirements and follows Stoke Space's recent Series E funding round.

Practical Implications and Verification

Readers tracking developments in commercial and government spaceflight should note the distinction between projected timelines and confirmed operational milestones. Aerospace schedules—such as Virgin Galactic's projected 2027 commercial flights for its new Delta-class vehicle, Apeiron, or the European Space Agency's weather-dependent winter schedule for its Themis reusable rocket testbed—frequently face adjustment.
