China develops space-launched Mach 20 missiles capable of 30-minute global strike

China may be edging closer to a breakthrough in hypersonic weapons. A recent study by researchers linked to the PLA Rocket Force outlines a concept for launching hypersonic glide vehicles (HGVs) from space-based platforms, such as satellites or orbital stations. These HGVs, reaching speeds of Mach 20 (21,000 km/h), could strike targets globally in under 30 minutes, drastically reducing enemy reaction time.
Unlike traditional ballistic missiles, these gliders would re-enter Earth’s atmosphere with unpredictable trajectories, complicating interception. However, the study acknowledges key challenges: high infrared visibility due to friction-generated heat, limited maneuverability (3–5 G max), and weak communication links during final approach.
This aligns with past U.S. intelligence reports suggesting China tested orbital hypersonic systems as early as 2021. Meanwhile, Western programs—like the UK’s Team Hypersonics—focus on air-breathing scramjets for ground-launched hypersonic cruise missiles, emphasizing propulsion flexibility over orbital launch.
U.S. officials have warned of the strategic threat. In an interview last November, Defense Secretary Pete Hegseth noted that Chinese hypersonics could “take out 10 aircraft carriers in the first 20 minutes,” underlining their potential to disrupt global military balances. Parade footage of systems like the DF-17 reinforces China’s continued investment in high-speed strike capabilities.
