Answer: China
Notes: Chinese scientists have revealed a groundbreaking High-Power Microwave (HPM) weapon using Stirling engines. Stirling engines, functioning on external combustion principles, convert thermal energy into mechanical energy. HPM weapons, a subtype of Directed Energy Weapons (DEWs), use electromagnetic systems to convert energy and focus it on targets, causing physical damage. Capable of generating electromagnetic beams across radio and microwave frequencies, these weapons can potentially disrupt or damage targeted electronic systems.
