Abstract: The stealth technology of projectile is researched to develop a stealth projectile to counter hostile artillery locating and fire correction radar. The contour stealth design of projectile includes full-stealth and half-stealth structures. The full-stealth projectile structure is designed according to the full-stealthy design specifications. The full-stealth projectile is a subcaliber disc-type projectile. The full-stealth projectile has emarkable stealth performance, but it has the reduced power and hit accuracy. So a full-caliber stealth projectile structure is designed. The front bourrelet of projectile is not coated with radar absorbing materials and touches the bore directly to form a half-stealth projectile. The X and S band half-stealth projectiles were designed and manufactured. The half-stealth projectiles were searched and tracked by using an artillery locating and fire correction radar. Experimental results show that the half-stealth projectile has stealth performance. Key
