Don't go into Dyspnea. Going by your logic, we would never be able to push our sell. BTW do you know that China do have a watch station in Myanmar to keep a tab on all our tests? US has already done that in past with our missile tests.I was trying to draw your attention to the Chinese getting access to the Akash system and its computers and deciphering the coding done by us.
Now as we all know the missile itself does not have a brain. It only follows the commands and instructions given by the software. There are various sensors like accelerometers, gyroscopes, altimeter, IR sensors etc. The job of the main system computer is to take in all the readings from the various sensors and then choose a course of action. In a manned aircraft the pilot takes the decisions on what the aircraft should do by using the control surfaces on the plane. Using the human brain.
But in an unmanned missile the laws of flight are written down by the designers. The missile will do exactly as programmed by the designers. If the Chinese know how the Akash SAM will behave in various flight situations /conditions then they may know how to fool the missile.
Now consider if the Russians or the Chinese get their hands on the best American Aam the 120D missile. The Americans would have written down thousands or even millions of lines of coding to make the Aim120D what it is. Will it be impossible for the Chinese or Russians to decipher the code and then use that knowledge to devise counter measures for the Aim120D.
Countries strongly protect the algorithms used in their weapons.
Anyway let's see if we actually export the Akash and the Brahmos.
So they already have the missile performance recorded long back. In future too they would get the performance envelope of our missiles.
Now while selling us missiles, do you think Russians don't know the risk of running it on American hands? While selling techs to Ukraine, don't you think Americans know about the risk of running it over Russians? Opening up a missile or the getting hand on its FCS system is not going to unravel the whole secret of the missile performance.
In lay man term, if you get access to the computer of a car, would you be able to decipher the whole performance envelope of the car? For example would you be able to decipher the minimum turning radius of the car? Would you be able to decipher the drift it would cause in case of an emergency braking? For that you would need to build an exact copy of the car. In case of a missile, you would need a a dozens of clone to unravel its performance envelope.
Even China has been unable to make exact copy of missiles it received from Russia. As far as Akash is concerned, as I already said, it is not some start of the art missile. China has already build missiles of its class and well aware of its performance. Its the RADAR performance which is of concern. But as I have said earlier again, the performance of RADAR would depend on the client. Just like what we did in S-400 deal. Russians while pitching in for S-400 can't go on and say that its degraded in performance then their one. So we too can't say or do the same. But yes, we could present an entirely different RADAR version based on the client request.
