2. Fattah-2 missiles:
Fattah-2 missiles are the latest version of hypersonic missiles developed in Iran. This sort
of missile is made up of a combination of hypersonic glide vehicles (HGV) and hypersonic
cruise missiles (HCM), which has unique features. It seems that the Fattah-2 missile is
still in development and more versions will be manufactured in the future.
The Fattah-2 missile utilizes the configuration of hypersonic cruise missiles. The acronym
HCM, which stands for Hypersonic Cruise Missile, is written on its nose cone. The shape
and combination of the nose cone is similar to the X-51 hypersonic cruise missile.
However, the X-51 missile uses a ramjet engine that requires air intake, whereas in the
Fattah-2 missile, air intake and ramjet engines are removed, and instead, a liquid fuel
rocket engine is used. This will not affect the missile’s performance.
Specifications of Fattah-2 hypersonic missile:

Weight: 3500 to 4100 kg
Warhead: ~ 500 kg
Explosives weight: ~ 200 kg
Guidance: combination of INS and GPS
Design:
The Fattah-2 missile consists of two parts. The first part is the Fattah solid fuel
booster, which has not changed from the initial version. The second part is the
gliding warhead, which separates from the booster and has a liquid fuel rocket
engine.
The overall shape of the Fattah-2 gliding warhead is very similar to the Boeing X-51
missile, but with the difference that its air intake has been eliminated and a rocket engine
is used instead of a ramjet engine.

3. The explosive material is located at the beginning of the warhead, followed by an
inertial guidance and GPS system along with a computer that is responsible for
guiding the warhead to the final stage of impact. After the guidance system, there
is a detonator container (yellow piece), followed by a liquid fuel tank and an
oxidizer tank, and finally a rocket engine that appears to have the ability to change
the missile’s trajectory.
At the end of the warhead, there are four fins, two of which form a line with the
bottom of the warhead and are fixed, responsible for producing lift force. The other
two fins are designed to change direction and have the ability to rotate around an
axis connected to the body. Fattah can also modify its plane of movement in space.
It can perform lateral movement to the left and right, up and down, as well as rotate
or integrate within the upper atmosphere.
