This is actually a good application for them - ultra long loiter aircraft, which have all kinds of uses - imagine one of them that is used to bounce wifi signals off of to provide broadband. Terrain ceases to be a problem, and the drone can circle overhead high enough to reach huge areas.

I think balloons actually were used, at least as a research project, to bring cell service to parts of the... Dakotas maybe???

Tethered radar blimps were used for some time along the Mexican border as part of the drug interdiction effort.
Got to see the forms a (mutual) supplier used to lay up the giant secant squared antenna that went inside the envelope. A pattern makers dream.

Back in the 80's, The Navy was looking at dirigibles as a possible long term ASW, open ocean radar and search platform. It was planned to be used against drug smugglers in the Caribbean and along both coasts. A single dirigible with a 2 section crew could stay aloft for up to two weeks at a time. While feasable, it never really got past the panning stage.
They used them for that during World War 2

Boeing was working with a Canadian company to develop the Skyhook heavy lift helicopter dirigible hybrid. It looks like it's stalled for lack of development money.

See, I would think it would be better to shape gas envelope like a aerofoil, so that you could get some additional lift out of it.

The worst part about being airship pirates?

Yeah, I kind of like Abney Park. Haven't bought any yet, but expect I will, provided I am spared....

Actually, airborne early warning. YEZ-2A. I worked on the program. Massive beast - 2.5 million cubic feet, 425 feet long. Fly-by-light flight controls (for 1987, bleeding-edge technology). ~60 hour endurance unrefueled...but we planned to refuel from ships, stretch the missions to 30 days aloft. Wonderful, fascinating machine.
