Well they would have minimal profiles, be able to loiter for quite a while, and it's a lot cheaper to field, maintain, and replace a network of high altitude balloons than to field the dozens, if not hundreds of combat airships needed to maintain an effective observation fleet over a hostile continent.

Salem would probably take steps, but if you can keep the balloons coming, then you can keep tabs on her.
