Iran’s new “Baby Bottle” Shihab.

Written by The Middle East Missile Monitor

Monday August 23, 2004

On August 11th, Iran announced a test of a new version of the Shihab 3 missile, described by Iranian sources as “More accurate”. Iran also released a video showing a missile taking off from a towed launcher indistinguishable from the Shihab 3 launchers paraded last year during the “Martyr’s Day” celebrations. Somewhat confusingly, senior Iranian officials are quoted by Jane's Defense Weekly in its August 18th issue as insisting that the test did not include a live firing. Rather, it was a “Field exercise”. Another source, the Website newsletter “Middle East New Line” (MENL), elaborates on the JDW disclosure, describing the test as a “Dry” field exercise of the entire Iranian command, control and communication (C3) structure – from political leadership down to the Iranian Revolutionary Guards troops that responded to an alert in the military base in Dasht-E-Kabir near Esfahan, took the Shihab3 missile from its silo and loaded it on the launcher.
The most surprising piece of information in this welter of confusing and contradictory reports about the events of August 11 is without doubt the video footage of the missile launch released by Iran. The silhouette of the ascending missile was new. From the reentry vehicle (RV) base down to the fins, the missile was practically indistinguishable from the long familiar “Shihab 3” as seen in previous flight tests. The front section of the missile, however, was radically different. Instead of its usual ‘Dunce Cap” RV of all the shihab missiles displayed to date (Figure 1 below), the August 11 image shows a completely different RV, consisting of a conical front section, a cylindrical (or shallow angle) mid section, and a flared skirt at the rear section (Figure 2). This three-section geometry is remindful of the early single warhead RV’s of both Superpowers during the 1960’s – the “Baby Bottle” shape of the early Polaris and its Soviet equivalent, the SSN6 (R-27).
The poor quality of the images makes it difficult to decide whether this new silhouette is merely some visual effect – deliberate or otherwise – in the released footage, or a true photographic record of a new version of the Shihab 3 missile. Several colleagues verified to the present writer that they too observed the same anomaly in the shape of the missile. With all due reservations, than, we shall proceed with an assumption that the released images are truly representative.
Changing the aerodynamic shape of an RV is not trivial. It impacts on the controllability of the entire missile during its boost phase, and on the trajectory, accuracy, and viability of the RV during re entry. Hence, if the Iranians decided to take this step, they must have had compelling reasons to do so. The most compelling reason would be the installation of a weapon that must fit into the RV but whose geometrical shape and center of gravity (CG) do not support installation in a conical RV. It is reasonable to assume that the weapon’s CG is well to the rear, so that its installation in the previous RV of the Shihab would make it unstable during reentry. A sharp angled “Skirt” or ...

Iran unveils redesigned Shahab missile

Following analysis of footage of an 11 August Shahab test in Iran, Rubin claims the new Shahab design bears a significant resemblance to the Soviet-era SS-9 inter-continental ballistic missile (ICBM), now withdrawn from Russian service. According to Rubin, the Shahab re-entry vehicle of conical design has been replaced by a smaller vehicle shaped like a 'baby bottle' neck. Also, the cable raceway that ran along the propellant storage sections in ...
