Increasing the range of conventional bullets has become very important today. Previous technologies increased the range of bullets by a certain amount. These former technologies in artillery shells include the technology of creating a bullet at the base of the bullet and the use of rocket bullet technology. Today, large research companies are using new technology to increase cannonballs. According to these companies, new technologies can increase the range of 155 mm bullets to 155 km. The new technology is the use of solid fuel ramjet technology, which is now very popular. Ramjet motors have no moving parts and at first glance look like a hollow tube, which is mostly used at supersonic speeds. In such engines, in order for the engine to start, the air speed must first reach the required value. In such a case, the ramjet engine will start automatically. In this research, the technology of ram jet bullets and the progress made in it have been investigated. According to the investigations, one of the most important future technologies in artillery shells is the use of ramjet technology.
