They can all mount a load of some 16 or so Mk-82s between the engine nacelles. It's all unguided though so it's really old school in that regard.
No support for FFARs or any kind of LGB on the normal version, only iron bombs.
But to be fair, you can get quite a few on there and you can go very fast so you can almost use it like a mini B-58 if you get good at it.
