Space Transportation and Lingkong Tianxing Technology introduced the Yukong Ji-1000 (YKJ-1000), a new hypersonic missile with speeds up to Mach 7 and a range of 500 to 1,300 kilometers, which is already in mass production and claimed to cost one-tenth of traditional missiles.Promotional footage by Lingkong Tianxing showed test launches and animated simulations targeting Japan, escalating tensions due to comments by Sanae Takaichi about potential Self-Defense Forces intervention and subsequent defensive measures announced by Japan.
