<p>A directed-energy irradiating apparatus includes an FEL apparatus 20 and an HPM apparatus 30. The FEL apparatus 20 accelerates free electrons by using microwave supplied from a microwave source to irradiate an FEL beam and outputs remaining microwave. The HPM apparatus irradiates an HPM beam generated based on the remaining microwave outputted from the FEL apparatus. It is possible to destroy a target even in a situation that a destruction effect by the FEL beam cannot expected, while maintaining the destruction ability of the FEL beam.</p>
