SAM system based on Nasr missile

[mufti]

Yes this is a good idea. The Russians are trying to become closer to us. It's time we take an initiative.

Lol the information will be shared with Indians about the technology and all. How can one be so stupid ?

 

[Icarus]

Though I think @Oscar would be able to answer this question with a lot more certainty than me.

 

[sparten]

The Nasr missile motor and fuselage could be used as the basis of a High Altitude long range SAM or ABM certainly

It would however not be as simple as replacing the warhead section with a guidance radar/seeker, writing a bit of code to link it to Radar and presto......... it would require several new pieces of equipment (a new nozzle for instance), with the attendant integration and testing, not to mention needing a special Radar,a seeker, equipment to reduce time needed for firing.....

5 years at least.

I have thought of that. I'm sure the Russians wouldn't do that. At a time when India is shifting towards the U.S.

 

[RAMPAGE]

Well for starters, the motor will have to be able to work past only a parabolic trajectory and instead be able to give chase to an aircraft at Mach 3-5 for anywhere from 30 to 50 seconds while constantly maneuvering to keep the aircraft on its 12. Its a massive ask of a platform that was meant to follow a predetermined trajectory to a stationary or slow moving (sub-100kmph) target.

Oh ok!

Maybe we can use the case and launchers with our future SAM. The launcher is very sexy.

Most of their defence equipment still comes from Russia.

NASSR is a Surface to Surface missile , meaning its fired from ground and falls flat on ground.
so its computation algorithms if any , are simpler , just need location / distance / and trajectory for a reasonable accuracy hit. Best odds are when the target is stationary. Ground object is moving at a turtle pace 20 km /hr or so


When you are working with SAM (Surface to Air) , you are dealing with a target in air which is moving has altitude that varies and it can turn suddenly. So it needs a much more complicated system which can track the movement of the object in air , and predict its movement so when the Missile is filed it can pre-judge the position of moving target and aim to hit the moving target. The moving target could be moving at Mac2.0 and then turning or looping or diving , any combination is possible

Now we are looking at 5-10 Million lines of code written for such systems more complexities and you also need to get new data from radar every mili second so the system knows where the object is. You also need great deal of math involved and not to mention high level of computing power available to make a system work.Also various technologies and knowledge branches need to work just right to make an operational SAM work.

So its not easy to convert a Surface to Surface missile into SAM.


Russia worked on their systems since WW2 , and have gradually made improvements and now they have used their past knowledge to build S300 System.

Pakistan if they start from scratch would need 10 years to make a reasonable SAM system
less time if they have already started like 8 years ago on such system

USA when they were constructing Patriot systems these systems only worked 50-60% of time and they would fail miserably on many ocassionsl however USA kept selling these outdated systems to others collected Billions and then continued to improve its efficiency. So over 8-10 years they continued to improve reliability of system



In Theory do we have resouerces for SAM made in Pakisan?

Yes

Missile units (Yes)
Radar construction (Yes) , we make radars locally for planes
Targeting technology (Yes) , we use this on planes / rpg for targeting objects and locking on
Mathematicians (Yes)
Physics exports (Yes)
Programmers (Yes)
Super computers (....grey area....), prototypes small enough to fit a truck
Tracking technology (...grey area but we are working with AWACS tracking technology..)
Custom Hardware (Money can get it)
Custom Software (Money can get it done)

Human Reources power is there just lacking official project designation and funding

 

[killerx]

converting NASR into SAM is not possible how ever Pakistan should build its own medium to high range SAM system plus should be potent against ballistic and cruse missile at some point, or some from china on installments

 

[AZADPAKISTAN2009]

For Pakistan:

A SAM purchase from China is best option which , opens Source of the technology to Pakistan to explore and understand and then reverse engineer that into a new system.

 

[MastanKhan]

I was thinking if it would be possible to develop Nasr into a SAM.

Will it need a new motor because it has to be more manueverable?

Hi,

It would be better with SD10B----but that would only be a medium range SA missile. We need to look into existing systems for LR SAM's.

There is too much investment needed for an SA missile system---it is better to get an existing system.

 

[maxpayne]

most illeterate idea. Nasr is very different platform and it is not possible to convert into SAM. If have funds and will, we can create new SAM from scratch

 

[war&peace]

Well for starters, the motor will have to be able to work past only a parabolic trajectory and instead be able to give chase to an aircraft at Mach 3-5 for anywhere from 30 to 50 seconds while constantly maneuvering to keep the aircraft on its 12.

'

Nasr reaches a Mach of 5.9 to 7.5 for the flight. The job of the motor is just to provide thrust and the motor in any of the SAM is nothing special.... as long as it can achieve a high specific impulse over short time.
The difference is in the navigation and guidance system. Unlike BMs inertial and satellite based navigation, SAMs use active radars, IR, UV and visual imagery to track the target and it is coupled with satellite (for long range SAM like S-400), ground radar and some other systems. Another difference is in warhead, SAMs normally use a smaller warhead than BMs and thus a smaller motor or a longer range can be achieved. NASR can provide a SAM with upto 40 km at an altitude of 20-25 km (65000-82000 ft) and F22 has the ceiling 65000 ft.

Nuclear tipped NASR SAM- indians gona sh!t their pants- lol

The rest of your comments are spot on, except for one, are you sure that it follows a "parabolic trajectory" ?

He is right if he meant to say that Surface-to-Surface Missiles follow a parabolic trajectory - parabolic in the sense that it goes up and comes down, and roughly forms a symmetrical inverse U shaped curve (of course, other factors could change this a little, but basically that's what it does)

@Icarus is correct, even though the proper term to use in this case would be 'ballistic trajectory' instead of 'parabolic' to avoid confusion, since a 'parabolic trajectory' means something entirely different in the context of spaceflight and orbits.
