I am not sure if the rudimentary type of RD-33 Iran possesses is effectively a turbofan, or somewhere between a turbofan or a turbojet with some kind of bypass. Up to few years ago, the early versions of RD-33 (1st series) was named turbojet even on Klimov website. Unfortunately, their website...

Investing on J-79 is nothing but wasting time and resources; while the advanced version of it i.e. AL-21F3 exists in Iran hands, and in fact more needed. Iran purchased around ~ 250 Phantoms with too many spare engines. Currently, only a quarter of the fleet have survived according to many...

Yes indeed they have purchased at least one unit: Iranian S-300 units are significantly more expensive than similar units other customers bought from Russia, and the reason is not clear.

It is not as easy as you said. All critical components have to be redesigned if more power is needed. Saving in fuel consumption is the only benefit which can be gained with minimum changes. Remember the compression ratios are also different.

It is very weird to hear that Iran has not received 48N6E2 for its S-300 batteries, or maybe he just wants to exaggerate about Bavar-373!

AL-21F-3 is the modified version of J-79 with superior performance in most aspects. Also, hard to find from other markets than Russia. So, may be a plan to work on it!

Great document, and I really appreciate for sharing it. Now we know the source of those S-300PT units. Yet, Tomb Stone Radar was not available with PT versions! Mystery continues and may continue for more years. So, we can now connect many of the dots: 1- Iran has possessed early versions of...

Some observations and ideas: 1- It is not clear why since the introduction of S-200VE system to Iran, the maximum engagement altitude (service ceiling) for all Iranian made AD systems has been limited to 27 km? Is it only a misleading information for media? Or 27 km is a threshold above which a...

I thought you already know that there is a secret island somewhere in Iran, where all these miracles take place. Also, all these modern Russian stuff such as Costa, Nebu, Rezonans, Gamma, S-300, Tor-M, Cornet, etc. you see have come from other planets, as according to Iranian forums and media...

No it is not! That one was fired from south of the country towards north (they said around Tehran state) to evaluate the performance of something, most likely Bavar 373. Definitely that Missile was not armed with a real warhead; otherwise it did not make any sense to put a huge population at...

It is not like what you stated at all. The interface module between these two units is an ‘option’ for the customers, and they need to pay for the interface cards/modules itself as well as programming, and commissioning. Spending only 2,300 man-hour can match with this kind of projects, though...

Time to time we need to read between the lines: during the show-off ceremony the reporter mentioned the retrofitted radar (Falagh) will help the S-300 system. So, maybe the story is that the Radar by self did not have any issue and was running fine, but Russians refused, or could not make the...

I that case how can they support their own radars, and other customers, if any? Iranian authorizes are well known for being dishonest with respect to claiming things have been done without the support of the original vendor. They expect the foreign and even domestic vendors such as MOD come and...

Finally, PeeD made one right comment in this forum (just joking, of course :D). One can see both features at a time in Meraaj-4:

Are you sure the second one is not Ghamar? The second one looks smaller considering the size of the towed trailer/transporter. I am just asking as I do not know how to differentiate these two, unless they are different versions of the same radar. Ghamar 3D Radar during the inauguration:

The first one you think is for Air-to-Air missions can be actually carrying a Chinese or maybe Iranian (as we do not know who first came up with the idea of using the Crotale’s platform for A2S missions; while both countries produce such platform) Air-to-surface Missile. I personally think the...

Do you know what “root cause” means? What you said is not the root cause, neither what aryobarzan said. What you mentioned is the consequence and what he mentioned is the effect. The question is what caused the engine to stop functioning? Was it the control system? Sabotage? Lack of training...

Beside rebuilding Damavand, could they finally figure out why Damavand-1 failed, and more importantly how to prevent it from happening again for Damavand-2? Did they buy any big crane this time? They can build 10 more Damavands there, but all of them will be still at the same risk of collapse as...
