ALCON,
Not sure if anyone noticed, but that missile in the video is NOT the "same old" Nasr AshM, it's something I at least least, have never seen before.
Here are the things I'm seeing:
- It has a small intake along the bottom, similar to that mounted on the C-802 but on a smaller missile. This means it's powered by a new, likely micro-jet engine.
- Booster motor is a totally new design. It's similar in concept to those used by China's C-602 and C-705 missiles.
- Given it's apparently dimensions and appearance, it definitely looks descended from the original C-704/Nasr design.
Essentially, we're seeing a turbojet-powered development of the C-704/Nasr. This also explains the need for a new booster design, since they couldn't simply mate the C-802/Noor booster design to the dimensionally smaller Nasr.
China did something similar when they designed the C-705. They started off with the C-704 and applied many of the technologies they developed for the large C-602 missile (planar wing design, new solid booster). Iranian engineers were apparently given the same task to perform.
The swap out of the original solid-fuel rocket motor to a small turbojet engine will likely mean a big increase in range, perhaps >100km (compared to the C-704/Nasr 35km).
Effectively, you get an AshM with similar range to the C-802 with a somewhat smaller warhead and in a more compact design.
