Most of the current ones can carry about a ton and a half, but larger ones would be able to carry a lot more: the Hindenburg could carry 232 t, for instance. The largest blades nowadays are 12 t; the nacelle with the transformer is the expensive bit; those can be as much as 55 t. The tower is more (twice that), but it’s usually transported as rings of 10-20 t each. As long as you can make the envelope airtight (and rigid), airship performances improve with scale thanks to the cube-square law. The limiting factor is the factory: they aren’t hangars big enough to make bigger airships, so you’d need an industry with predictable demand for larger ships.
