HELSINKI — Chinese launch startup Landspace has unveiled plans to develop a reusable stainless steel rocket.

The Zhuque-3 (Vermillion Bird 3) will use stainless propellant tanks and clusters of Tianque methane-liquid oxygen propellant rocket engines, according to a presentation by Landspace CEO Zhang Changwu at the Mingyue Lake Aerospace Information Industry International Ecosystem Event in Chongqing, China, Nov. 21.

The two-stage launcher will have a payload capacity of 20 metric tons to low Earth orbit (LEO) when expendable. Recovery of the first stage downrange will allow 16.5 tons to LEO, while a landing back at the launch site will offer a capacity of 11 tons to LEO.
