missiles)

Despite the limitations imposed by the UN sanctions
and the international arms embargo, Iraq was able to produce and field
the domestically designed Al-Fat�h composite solid-propellant ballistic
missile. The goal of the program, which commenced in July 1999, was
to develop a missile that could deliver a 300-kg payload to a range
of 150 km.
The Al-Fat�h missile was a solid-propellant ballistic missile weighing
approximately 1,200 kg with an overall length of approximately 6.3 meters
and a diameter of 0.5 meter for the main body and 1.4 meters with the
aft fin assembly. The airframe was primarily constructed from 4 mm thick
30CrMoV9 sheet steel. Iraq lacked maraging steel sheets of sufficient
size and quantity to manufacture Al-Fat�h motor cases. Without maraging
steel, the Al- Fat�h motor case had to be constructed from 30CrMoV9
sheet steel. The aft fin assemblies and nose cones were constructed
of aluminum.
For propulsion, the Al-Fat'h utilized a motor that weighed between 770
kg and 856 kg (828 kg ?). Manufacturing the Al-Fat�h solid-propellant
motor presented several challenges. Specifically, Iraq lacked preferred
materials for the motor case and insufficient solid-propellant mixing
capacity.
The two planned Al-Fat'h missiles utilized different guidence systems.
The unguided Al-Fat�h used simple aft stabilization fins. The guided
version of the Al-Fat�h would have had a relatively complicated control
system, with canards, actuators, and a strapdown INS with an indigenously
developed computer and imported gyroscopes and accelerometers. |
