👉 Demonstrator Missiles (DEMs) are a class of unmanned, short-range ballistic missiles developed by the United States primarily for testing and validation purposes. Unlike traditional ballistic missiles, DEMs are designed to be launched from the ground or sea, allowing for rapid deployment and testing of missile systems without the need for a dedicated launch platform. These missiles typically use a simple, robust design with a single stage and a short range, often used to evaluate the performance of guidance systems, propulsion technologies, and control mechanisms in a cost-effective manner. They are an essential tool for advancing missile technology and ensuring the reliability of future military systems.
