What are the specs of the Cowboy Space rocket and its Clydesdale engine?

Baiju Bhatt described a reusable two-stage stainless-steel rocket about 86 meters tall and 4.7 meters wide, sized to be road transportable and to lift about 15 metric tons to orbit. It burns liquid oxygen and liquid methane. The booster carries nine Clydesdale gas-generator engines and the upper stage one, each making about 300,000 pounds of thrust. Worn-out booster engines get a last flight on an upper stage.

• Bhatt said the gas generator was first tested at NASA Stennis after less than five months of work.
• Bhatt called the Clydesdale a reliable, fast-to-build engine rather than a racehorse.
