Its your countrymen who have lost sleep over the intermediate range issue... intermediate range is not 1000-1500km.. but 2500-5500km which lies between short range and long range..
Intermediate-range ballistic missile - Wikipedia, the free encyclopedia
neither does this makes your Shaheen 1A fly more than 1000km.. In fact its range would still be around 700km.. If it carries the same amount of payload and not a reduced one.. there is no modification done on the missile body Its still the old shaheen.. without those small canards(unless the weight is reduced substantially by the use of composite casings but in this case the weight has rather increased according to source and links posted)... Its your Generals and officials who are claiming nonsense...increasing the range of missile is not a big issue here... I can explain how its done in solid fuel missile but that would go over your head.
Now on the accuracy part.. care to explain what was put inside the last stage to make it more accurate or what kind of guidance was used through which the small thrusters correct the course in space.. or what CEP has the missile been able to achieve on the basis of deflection in degree per hour.
What time the missile took to reach its target and what trajectory did it follow...(the height of apogee..etc..).. before reaching the conclusion that the missile is the improved version and not just another version... until you have the answers of the following for your ALLAH's sake stop concluding baseless conclusions like imaginary range figures and alien abilities(such as being invisible to radar).
