五角大楼官员说：“给乌克兰送战斗机毫无意义。他们需要的是地对空导弹、携带式对空导弹、反坦克导弹和无人机，因为他们有效地使用了这些武器。这也是俺们工作的中心（It makes little sense to us that additional fixed-wing aircraft is going to have somehow solve all these problems. What they need are surface-to-air missile systems, they need MANPADS, they need anti-armor, and they need small arms and ammunition, and they need these drones, because that's what they're using with great effect. And so, that's what we're focused on）”

此外，俄国军机也不敢随便进入乌克兰领空，很多空对地导弹都是远程发射。乌克兰还有56架战机，每天飞行5-10小时。

双方都还有大约90%的战斗力（Russia still has roughly 90% of its invading combat power still viable, with Ukraine falling just under 90%, the official said）。
