China to convert ground-launched artillery into gliders to hit aerial targets, planes
Reports have emerged that China is actively converting its ground-launched rocket artillery into low-cost, air-targeting precision gliders. If successful, this could rewrite the history of how cheap munitions could be used against aerial threats. Led by Professor Zhang Shifeng at the National University of Defence Technology in Changsha, China, the research team has developed a prototype called Tianxing-1 ('Sky Star-1'). This consists of a modified rocket artillery round with lift-generating wings and adjustable tail fins. Rocket artillery, like America's Global Mobile Artillery Rocket System, launches rockets rather than conventional shells. Unlike traditional tube artillery, which relies on explosive charges to fire projectiles, rocket artillery uses self-propelled munitions that do not require a barrel. Typically mounted on mobile platforms, rocket artillery systems can deliver rapid, high-volume barrages over a wide area, making them ideal for saturating enemy positions. While generally less accurate than guided missiles, modern systems increasingly feature GPS or inertial guidance to improve precision. Rocket artillery is valued for its mobility, speed of deployment, and ability to overwhelm defenses with concentrated firepower. Interestingly, it is also one of the oldest forms of artillery, with specimens dating back to the early medieval period in China. Modern bona fide rocket artillery, on the other hand, first appeared during World War II, with the German Nebelwerfer family of rocket ordnance designs first used in battle. Other examples from the time include the Soviet Katyusha series and numerous other systems employed on a smaller scale by the Western Allies and Japan. According to a report by the South China Morning Post (SCMP), the new Chinese Tianxing-1 transitions into a glider, adjusting its course mid-air to hit stationary aerial targets using passive flight (it doesn't have an engine after the boost phase). The munition is particularly fast, traveling at subsonic speeds (~656 feet-per-second or 200 m/s). Moreover, it uses a new guidance algorithm that reduces targeting error from 50m to less than 1m. The new rocket is capable of multi-angle attacks, but is not yet suitable for engaging moving targets or fast aircraft. While it's too slow to chase jets or drones, the Tianxing-1 could be deployed in large numbers as a cheap area denial or aerial ambush system, particularly against slower or hovering targets like helicopters or loitering drones. Reports also suggest that the new system could, in theory, change how armies think about anti-air warfare, opting for a middle ground between expensive surface-to-air missiles and dumb artillery. As impressive as the development sounds, it is important to note that the Tianxing-1 is designed as more of a training or a tech demo tool rather than a deployable weapon. However, it successor, Tianxing-2, has reportedly completed successful tests with more advanced targeting systems in northwestern China as per SCMP. Details of the team's work were published in the April issue of the Chinese Journal of National University of Defence Technology. The study highlights the challenges of guiding unpowered, low-speed gliders to hit "targets in the air." If perfected and deployed in swarms, this could add a new layer to anti-air defences, especially in scenarios where cost, saturation, and surprise matter more than speed or raw firepower.

Chinese defence scientists seek to turn old rocket artillery into plane-killing glider
The Chinese military marked the world's first recorded use of rockets in combat nearly eight centuries ago, when they deployed fire arrows and possibly gunpowder-launched grenades against Mongol invaders in the Battle of Kaifung-fu in 1232, according to Nasa. Today, Chinese scientists and engineers are pursuing technological upgrades to transform the affordable, mass-producible traditional rocket artillery into a system capable of striking aerial targets. A research team led by professor Zhang Shifeng at the National University of Defence Technology's College of Aerospace Science and Engineering has developed a small rocket named Tianxing-1 or 'Sky Star-1'. Unlike conventional rocket artillery, this guided munition features lift-enhancing wings and adjustable tail fins for extended range and powerless-flight manoeuvrability. Launched at an angle from ground-based platforms, the rocket rises to a designated altitude before transitioning into a glide phase, where it autonomously adjusts its trajectory to engage targets. The Tianxing-1 operates on principles similar to hypersonic glide missiles, but travels at a far slower pace. Its maximum speed of 200 metres (656 feet) per second, or just over half the speed of sound, may see it struggle to chase high-speed aircraft or drones.
