Tactically Responsive Space Launch assesses a country's space resilience during challenging situations, such as conflicts, and China excels in this aspect.
Researchers Corey Crowell and Sam Bresnik at the CSET used publicly available information about launch vehicles, space launch events, and the number of satellites placed in orbit to determine the advances made by the country over the past decade.
The researchers found that China had doubled its number of satellites in orbit in the last four years with 419 new ones being launched since 2019. In addition to absolute numbers, the country was also placing these satellites in diverse orbits such as the cislunar orbit for its Queqiao communications satellite and elliptical Molniya orbits to extend coverage of Earth's Northern Pole.
Despite these significant advancements, the country still lags behind the US in terms of technological superiority, with the exception of one area: tactically responsive space launch .TRSL is a measure of space resilience for countries in low-likelihood but high-consequence scenarios such as a conflict. Higher capabilities in the TRSL domain allow countries to quickly replace their space infrastructure.
Beijing has been building its TRSL resilience through smaller and mobile launches made possible with the use of solid-fuel vehicles. In contrast, the US uses liquid-fuel rockets which require extensive infrastructure.China's first successful demonstration of TRSL dates back a decade when it launched the Kuaizhou-1 in 2013.
The Kuaizhou-1A can be launched within seven days of arriving at its site and requires nothing more than an area the size of a basketball court for a launch that could potentially put it into orbit with a small constellation of satellites, the
