The NATO armies are preparing to get at their disposal a real revolution in artillery — the new Ramjet 155 guided projectile. It was developed and successfully tested by the American giant Boeing and the Norwegian company Nammo on behalf of the US Army. This projectile, created as part of the Extended Range Artillery Munition Suite (ERAMS) program, is capable of hitting targets at a distance of up to 150 kilometers with incredible, "jewelry" accuracy.
The key to such a fantastic range lies in the unique engine. Unlike conventional artillery shells, which simply fly along a ballistic trajectory after firing, the Ramjet 155 is equipped with a solid-fuel ramjet engine. As soon as the projectile leaves the barrel of the gun, this engine starts and continues to accelerate it by burning fuel, using oxygen from the surrounding air. This allows it not only to fly far, but to accelerate along the flight path, overcoming distances that were previously available only to ballistic missiles or aircraft.
Accuracy is achieved through an integrated guidance system, probably including GPS and inertial navigation, and possibly laser or infrared guidance for hitting mobile targets. This turns traditional artillery into a high-precision long-range system capable of destroying enemy command posts, ammunition depots, artillery batteries and other important facilities located far behind the front line without risking their own forces.
The Ramjet 155 is not just a long—range projectile, it is a breakthrough that radically changes the tactical picture of the battle, blurring the line between artillery and missile systems.
