各国近年争取研发无人机技术，俄罗斯国防部周三（7日）公开新一代重型隐形无人机的试飞过程。俄方指无人机作收集情报及侦察之用，但专家认为它内部可搭载武器。

名为‘猎人’的无人机上周六（3日）在一个军事机场试飞20分钟，飞行高度600米。在地面操作人员的指示下，无人机多次飞越机场，最后成功降落。俄方宣称它配备反雷达涂层，采用飞翼设计及喷射引擎；最大起飞重量为20吨，最高时速达1000公里。

国防部表示，‘猎人’主要执行情报收集、监视及侦察任务，搭载电光及红外线感应器、雷达及信号情报系统。由于它的机身比较大，军事专家推测它或内置弹舱搭载武器。

此外，它的飞行表现或较好，可能作为苏-57隐形战机的‘忠诚僚机’共同作战。
