Defense Minister Ahmad Vahidi inauguration a production line of Nasr anti-shipping missiles on March 7th 2010. Pictures and video were also aired of it being tested during the latest round of "Unity" naval war-games.
The missile itself seems to be based off both the Chinese C-704 as well as the TL-6 and can be fired from a variety of platforms including land batteries and naval platforms such as the China Cat fast attack boat.
The Chinese have a long history of close cooperation with Iran when it comes to anti-ship missiles for obvious reasons, both are looking for a way to hamstring the worlds most powerful navy. In fact, i suspect that the relationship is not just a one-way street where China sells Iran their missiles, but the short timeliness involved almost necessitate involvement of Iran in the research and development phase.
One interesting feature about this is that there appears to be actually two missiles, one based off the TL-6, and the other based off the C-704. They are very similar missiles so it's not a readily apparent difference, but it exists in the shape of the fins, the TL-6 having static fins (as in the picture below showing it's launch from the C-14 China Cat) whole the C-704 has pop-out fins like on the Noor/C-802, like in the picture below of it on the rack in the factory.
Lastly, a curioisty during the exhibition showed the "Nasr-1" partially in the launch tubes but instead of having the flip-out fins, it didn't have any but the control surfaces instead. This is particularly puzzling as it showed the control fins attached where the glide fins are normally located (about midway on the missile) the missile displayed only had the warhead section on display, which isn't necessarily that odd, but the fin's position relative to it was. This is pictured last. The glide-fins were displayed alongside this missile(not pictured here), but had no where to be attached. This is a real mystery to say the least.
