“The U.S. government said Wednesday that it has approved support for Japan to develop the country’s upgraded Hyper Velocity Gliding Projectiles (HVGPs).”
“Under the support program, Japan will pay $340 million to receive assistance for the missile’s development, including conducting tests in the United States.”
“HVGPs, which are launched from the ground, travel at supersonic speeds from high altitudes and fly in irregular trajectories, making them difficult to intercept. The Japanese government is developing the missiles as part of its standoff capabilities, to strike enemy units that land on remote islands from outside their range.”
