Small ones anyway. W80 [1] W54 [2]. Most of them are over 500 lbs.
High altitude weather balloons on the other hand can carry up to 8000 lbs like the one from China the US let meander coast to coast over several military installations which could carry a B53 nuke after small modifications. Detonated at a high altitude could shut down the power grid coast to coast.
