LONDON — Future air defense for naval vessels and combat armor may include a defensive escort of uncrewed vehicles equipped with electronic warfare measures or drone-killing cannons, according to the technology director at BAE Systems, Europe’s largest defense company.The logic follows lessons learned from recent naval engagements that dance around the sweet spot of hitting targets from a safe distance, with sufficient reliability, while spending as little on interceptions as possible.Relatively inexpensive drone countermeasures already fielded, such as electronic warfare or cannon fire, tend to be shorter range or have lower success rates, Robert Merryweather, group technology director at BAE, noted at a briefing on layered drone and missile defense at the DSEI UK show here.The solution may be to push them out to be a first line of defense, with more expensive high-end systems as a backstop, he said.The cost asymmetry防御无人驾驶飞机一直是西方军舰保护红海的运输的问题，因为海军最初使用数百万美元的地表到空中导弹来摧毁胡塞无人机，然后更改教义以允许一些无人机接近船上大炮和范围的范围，但您的电子战争的每次镜头每镜头每次射击。 “目前，精美的事情最有效，因此您必须首先使用它，而在损耗的情况下，这是不可行的。”武装部队目前面临着“可怕的决定”，即它们是否允许它们是否允许在电子战争范围内接近无人机威胁，这是最低的成功范围，但与昂贵的Miless相比，它是最可持续的，是昂贵的MILDER。护卫舰以更远的距离识别威胁，使机组人员可以选择允许威胁
