The Shahab-3B differs from the basic production variant. It has improvements to its guidance system and a warhead with a greater range, a few small changes on the missile body, and a new re-entry vehicle whose terminal guidance system and rocket-nozzle steering method are completely different from the Shahab-3A's spin-stabilized re-entry vehicle.<ref name=":1">{{Cite web |title=ODIN - OE Data Integration Network |url=https://odin.tradoc.army.mil/WEG/Asset/Shahab-3B%20Iranian%20Surface%20to%20Surface%20Medium%20Range%20Ballistic%20Missile |access-date=2024-04-14 |website=odin.tradoc.army.mil}}</ref>

The new re-entry vehicle uses a triconic aeroshell geometry, or "baby bottle" design, which improves the overall [[lift to drag ratio]] for the re-entry vehicle. This allows greater range maneuverability, which can result in better precision. The triconic design reduces the overall mass of the warhead from an estimated {{convert|1|metric ton|lb}} to {{convert|700|kg|lb|abbr=on}}.<ref name=":1" />
