That link does not answer these questions. :rolleyes:
Apparently Akash can not hit an Super Sonic aircraft and the chances of out running the Akash is HIGH!

Two main disadvantages are.


1) The speed of Akash is only Mach 2.5 and so an aircraft with full after burner can easily out run it at a distance.

2) The altitude reach of Akash is some what confusing, i have read it is only 20,000ft but there are other reports that seem to confuse the Radars visibility of 59,000ft with Missiles ability.
their are various configuration in which Akash system can be deployed in network centric environment.


as shown in the AKASH

yes it is true that Fighter can over run missile using after burners for few minutes, but in net centric environment when within the range of missile battery it will fire on it making it difficult for it to move out of its kill zone.

Akash can hit a supersonic target. You are talking about tail chase. But Akash does not do tail chase, only sometimes. Akash follows proportional navigation where the radar assumes the target will have a future position at a particular point and send the Akash to that point at the same time or before the target reaches that point and then intercepts it. Missile interception has a lot of guess work involved. That's why multiple salvos are fired to increase kill probability.

2) The altitude reach of Akash is some what confusing, i have read it is only 20,000ft but there are other reports that seem to confuse the Radars visibility of 59,000ft with Missiles ability.
Akash's altitude for interception is 500m-15Km and range is 20-25Km.

@saya again the altitude is a bit lagging?

The speed to, the patriot travels at mach 5 and akash at half the speed.

There've been a series of test firings of the army and air force versions of India's Akash SAM these last couple of weeks. Dug up some of this archival footage from tests a few years ago, which also show ripple firing and salvo tests similar to the ones happening currently.

GK things work differently, once a enemy aircraft is found by ATC, then he takes the decision to send in interceptor or use SAM at his disposal, that also depends on number of factor including the altitude at which enemy plane is flying.

Patriot is over kill for any plane, we can send in our AAD, but it is over kill.

God ! Even in a defence forum the ignorance about how SAMs work is as bad as it's in comments section of news papers. Let me point out some very basic pointers about a SAM, AAM.

1) No SAM, AAM is 100% sure to hit any target.
All they have is a kill probability ratio which may be anything between 10% to 90% depending upon conditions. No missile in the world has a 100% kill probability, not even 90%

2) Somewhat like we studied about probability in school, to increase the chances of a successful hit, more than one missile is launched at a single target. Even then kill probability never reaches 100%, because a lot depends upon aircraft being targeted too

3) There is indeed a no escape zone condition in which an aircraft is considered as good as dead, but it's dependent on kill probability ratio and can be achieved only after launch


Last thing, why the comparison and derision based upon it's similarity with SA6 ? Even if these missile look somewhat similar, propellant, egine, sensors, radars being used are very different. Same people will moan how China is copying everything and why doesn't India do the same. Strange

India should go for a Semi Active Radar Homing version for Akash, Line of Sight Command Guidance Air Defense systems are easy prey for Anti Radiation Missiles.

Yes. And NEZ decreases as the target maneuvers.

They said that about the F117. A simple SA-3 was sufficient to bust that myth.
If detected, the F-117 can be shot down.

Regardless of whether the SR-71 is detected or not, it cannot be shot down.

Case in point, the Mig-25 over Islamabad. An IAF Mig-25 flew over Islamabad for a recce mission. Went supersonic, the sonic boom broke a lot of windows in the capital. F-16s chased it and could do nothing. There are some things you cannot touch even if you can see it out the window.

meh, with the right weapons anything can be shot down. btw, the blackbird did not need to get shot down. 40% of the planes decided to crash without any enemy around.

SA-6 is not a bad system to reproduce in Israel-Egypt war it reportedly destroyed
64 Israeli planes.

Any links for the same ?

Also the SA6 was heavily re modified during the Iraq invasion 2004. The heat seekers of Igla missiles were added on to that.

actually i like the point that you bring up about the SR71, there is a reason why it was retired and its concept was not taken further! for example there is no bladder for fuel as there was almost no substance that could withstand the temperatures so as a result fuel just kept leaking from the plane even before it took of, until it reached a certain speed and and temperature causing the titanium fuselage to expand and make a seal fuel kept leaking....
