From what I know that is a bit dated, and not classified, they only have an older Soviet style missile capable of submarine launch but have no subs to launch them.

Well, they are building their own diesel eletrics now. We don't know if AIP equipped. But the Club-K can be fired from a torpedo tube as well as from containers. And there is a huge range of Iranian missiles, some of which may be able to be fired from a tube and carry a significant payload.

Russia Will Equip Iranian Subs with Missiles

Excerpt mentions Club-S at least. They are refurbishing the Iranian subs however.

Also, the new anti-ship missile complex Club-S with the target distance of 200 km will be installed on these subs. The refurbishing of each sub would be done under the contract which costs anywhere from $80 to $90 million.
