II. Verifying Sham Freedom Missile Capabilities: Range, Quantity, Accuracy
Range
We start by plugging in the missile dimensions we had approximated in Part I of this blogpost into OpenRocket, a rocket flight simulation program:

To approximate weapon weight, I assume an all-steel body, and an 8 kg TNT warhead, as noted in forum posts on similar locally manufactured missiles, and about the same as the Qassam II.
For the missile motor, I select a Contrail Rockets O6300.
Although OpenRocket is designed to model civilian model rockets, the CR O6300 total impulse, or the aggregate of force impacted by the engine over its burn time, is within 30% of a 122 mm Grad.
To establish a performance ceiling of the Sham Freedom missile, we may therefore assume an efficient rocket motor in the vicinity of a military grade weapon, which OpenRocket handily models. This is the same conclusion arrived at by citizen journalists in the "Who Attacked Ghouta?" blogspot when estimating UMLACA rocket range during the Damascus gas attacks.

We assume average weather conditions, and the previously determined launch angle of 58.54. Our flight simulation yields a range of approximately 7 km, as reported by our missile source, thereby tentatively confirming the Sham Freedom missile claimed range.

Unfortunately, other claims regarding Sham Freedom Missile capabilities, i.e. a strike accuracy of “80%,” and a “500” unit stockpile, are more difficult to verify.
