here are some old news about this capacity:
ISLAMABAD (August 13 2009): Pakistan is contemplating developing an Inter-Continental Ballistic Missile (ICBM) with a 7,000 km range to make the country's defence impregnable and strengthen the armed forces of the country against any offence. The plan was evolved after successful test fire of Agni IV, the Indian ICBM system with a target range of 6000 km, which caused an imbalance of power in South Asia, extremely well informed defence sources told Business Recorder here on Wednesday.
Sources maintained that preparations are underway for the development of this long range ballistic missile and very soon it would be test fired. It would have the capacity to carry conventional and nuclear war heads. This missile, if successfully test fired, will be a milestone in the history of the country and a major achievement of scientists and engineers of Pakistan.
The possession of this ICBM not only will make Pakistan's defence impregnable but will also help create a balance of power in the region, which defence analysts believe was disturbed by the Indian test firing of Agni IV missile with a range of 6000 kilometres.
This scribe contacted high officials of the Defence Ministry who claimed ignorance of this development and refused to comment on this matter. The Director General of the Inter-Services Public Relations (ISPR), when contacted by this scribe also said that he was not aware of the development of the ICBM with a range of 7000 kilometre. It is pertinent to note that India recently test fired the 6000-kilometer Agni IV Missile with a capacity to hit and destroy targets deep in China.
See the article proves that the Agni IV missile is operational and exists unlike the Pakistani ICBM which is still not developed
AGNI III which is tested has a range of 3500km
and India want to convert AGNI III to 5500km range(Standard ICBM)
which is not tested yet
and indian missile take decades to complete
The 7000km range missile will be successfully tested in between 2012 to 2014
**** and chineese are very fast in developing new things.
