Following the September 3 military parade, the cutting-edge equipment showcased has remained a focal point of public interest. Among the highlights, the multiple LY-1 shipborne laser weapons have captured the imagination of netizens, who have affectionately dubbed them 'washing machines' due to their distinctive design. Yet, beyond the playful moniker, this self-developed Chinese technology has earned international acclaim as the 'world’s most powerful laser air defense system.' The parade featured not only the shipborne LY-1 system but also two compact laser weapon variants mounted on trucks. These variants are tailored for maritime air defense and offer mobile protection for ground troops, respectively. As a directed-energy weapon, laser weapons disable targets by emitting intense electromagnetic energy. They offer substantial benefits over traditional kinetic weapons, including cost-effectiveness and streamlined logistical requirements.
