K-4's 3200-3500 with 500-700 KG warhead (IISS) estimates
Sejjil-II 2500-3200 KM with same warheads
Ghaem is a tristaged solid fueled TEL SLV, which with a Re-entry Vehicle can hit probably +10000 KM. Its similar to Russian Yars or Minutemen in terms of ISP of stages. A very powerful machine as a nuke deliverer at distance.
Qased is another tristaged TEL SLV which if deployed with Re-entry Vehicle instead of Sat bus can probably hit 7000-8000 KM considering its ISP is less than Ghaem.
Both are IRGC products, different from SLVs of Iranian Space Agency ISA.
