The system first used a missile in a box-like launcher canted at an angle, just like the MIM-104 Patriot. However the missile was very large because of China's limited experience with solid-fuel rockets in the 1990s. Due to Russian assistance and technology transfers, the missile and launcher are in their present form, a transporter erector launcher with missiles inside a cylindrical container.[3] The missile apparently has a limited anti ballistic missile capability.
