    The Ghauri is a one stage ballistic missile missile with a throw weight of around 700kg and range of approx. 1,300 km.

    In addition to the Ghauri, Pakistan should develop a two stage Ballistic missile which would have a payload of around 2,500 kg and range of around 2,000 km. Such a missile would be logical extension to the Ghauri and in addition would allow Pakistan to deploy this new missile deep within Pakistan and still be able to hit every part of India with a thermonuclear warhead. (Hydrogen bomb)

    Secondly such a missile would increase Pakistan's ability to launch satellites. Satellites could either be launched on this new missile or this missile could be used to improve Pakistan's expertise to design a dedicated space launch vehicle.

    Pakistan launched a missile ranging 2000km long time ago. I think it was a year or something.

    Hatf 5/6 (Ghauri 1/2)

    The first launch of the Hatf 5 (Ghauri 1) ballistic missile in April 1998
    Type
    Intermediate-range, road mobile, liquid-propellant, single warhead ballistic missiles

    Development
    It is believed that the Hatf 5 or Ghauri 1 ballistic missile development programme started in Pakistan at the Khan Research Laboratories in 1993, but it was only publicly announced in 1997. An engine test was carried out in January 1998 and the first flight test was made in April 1998. Although Pakistan officials state that the Ghauri 1 is an indigenous design and development, it is generally viewed as having been based upon North Korean No-dong 1/2 technology. It is reported, though denied by North Korea, that 5 to 12 No-dong 1/2 missile assembly sets were sent to Pakistan between 1994 and 1997, for trials and to set-up a manufacturing capability. There have also been unconfirmed reports that Chinese guidance systems have been used, although these may have been passed through North Korea.
    Iran has developed the Shahab 3 missile, which appears to be similar to the Ghauri 1, and there are reports that Iran and Pakistan have co-operated together with North Korea and that the three programmes are closely related.
    A second ballistic missile, called Hatf 6 or Ghauri 2 (although the name Ghaznavi was used in 1998), was announced in 1998, with a range of 1,800 to 2,300 km, which uses a longer Ghauri 1 motor assembly. This missile might be similar to the Iranian Shahab 4 project. A Ghauri 2 missile was first flight tested in April 1999. Two other Pakistani missile development programmes were also named as Babri and Abdali and it is assumed that these might refer to follow-on systems with even greater ranges.
    A Ghauri 3 programme was reported to have been in development since 1994, with a range of 3,000 km, and first stage motor tests were made in July and September 1999. It is possible that one of these might form the basis for a satellite launch vehicle, probably based upon the North Korean Taep'o-dong 1 (SLV) design and using the Hatf 6 (Ghauri 2) missile as the first stage.

    Description
    Assuming that the Shahab 3 and Ghauri 1 missiles are similar it appears that the Ghauri 1 missile has a length of 16.0 m, a body diameter of 1.32 m and a launch weight of 16,250 kg. The missile shape is similar to that of the Russian 'Scud B' and appears to have been scaled up using the same length to diameter ratio. A payload of 1,200 kg and a separating warhead assembly could carry nuclear, chemical, HE or submunitions warheads. The warhead is thought to weigh around 800 kg and that the initial design was for a 15 to 35 kT nuclear warhead, similar to that tested by Pakistan in May 1998. The missile has a single-stage liquid-propellant system, probably using kerosene and IRFNA with a total propellant weight of 12,200 kg and a burn time of around 100 seconds. There is a single motor assembly, fed by a turbopump powered by compressed air. Guidance is believed to be inertial and reports from Pakistan suggest that Chinese assistance was given with the guidance, which seems likely to be true as an accuracy of 250 m CEP has been quoted (although this might have been 2,500 m). The minimum range is expected to be 400 km and the maximum range 1,300 to 1,500 km.
    Pakistan has several different types of mobile TEL in use with its ballistic missiles and is reported to have adapted the Russian MAZ 543 'Scud B' TEL vehicle with the addition of one or two more axles for use with the Ghauri 1 missile. There have been some converted commercial articulated vehicles used to carry the missiles for displays and also for the first launch in April 1998. A modified tank transporter vehicle was displayed as a TEL in March 2000, and it is believed that this vehicle can carry either Ghauri 1 or Ghauri 2 missiles.
    The Ghauri 2 missile is almost identical in shape to the Ghauri 1 and few details have been released. The missile is believed to be simply an improved and lengthened version of Ghauri 1, possibly using improved propellants with a new motor assembly. The length is believed to be 18.0 m, the body diameter 1.32 m and the launch weight 17,800 kg. The payload has been reduced to 1,000 kg and the nuclear warhead design may have been improved with a weight reduced to 750 kg. A lighter payload of 750 kg may be used when the maximum range is required. A maximum range of 1,800 km was reported after the launch, with the addition that this range could be increased to 2,300 km if the payload weight was reduced. It is possible that the real objective of the April 1999 flight was to test this missile as the first stage in a future satellite launch vehicle or two-stage IRBM.

    Operational status
    The first engine test on Ghauri 1 was reported in Pakistan in January 1998, although there were several motor tests made in North Korea in 1997 that might have been connected with the Ghauri 1 programme. The first flight test was in April 1998, over a distance of between 800 and 1,200 km, although the most probable distance seems to be 1,150 km. This flight lasted for about 10 minutes and was lofted to an apogee of 350 km. It is believed that Ghauri 1 entered operational service later in 1998 and that by mid-1999 there were some 5 to 10 missiles available for further tests or operational use. The operational missiles will be used by the Pakistan Army's 47th Artillery Brigade.
    Ghauri 2 is reported to be in development and the first flight test was made in April 1999. This flight travelled 1,165 km in around 12 minutes. It is not clear if this missile will be built for operational use, or for use as the first stage of a two-stage missile or SLV.
    Both the Ghauri 1 and 2 programmes appear to have been developed with considerable assistance from North Korea and to be based upon the No-dong 1/2 design and technologies. It appears that there has also been co-operation between Pakistan and Iran, as the Ghauri 1 and Shahab 3 missiles appear to be similar as well. The balance of evidence suggests that there has in fact been a co-ordinated programme between the three countries from around 1993.
    A Ghauri 3 missile has been reported to have been in development since 1994, with a range of 3,000 km, and two first-stage motor tests were made in July and September 1999.

    Yes, Shaheen II is pretty capable. It can act as a SLV. It has a range of 2500KM. The range can be increased by decreasing the payload.

    The only problem with the Shaheen 2 is that it has very low payload. To ever have a sattelite delivery vehicle, the missile must have a much higher payload in addition to its current range.

    yes indeed.

    you are correct.

    i think musharaf ment that multi stage shaheen program would be a platform on which they will build upon and create the SLV.

    and not in shaheen 2 as SLV in a more litral sence.

    But what about the sources which claim that there is a possible work of a ballistic missile which will have a range of 3500KM. If it will have that much range, i am sure that it will also have enough payload to be a platform that could be used for a SLV.

    Though indeed more information is needed regarding this issue.

    nop.

    you doent understand.


    the program not the missile.

    meaning they will use the scientists, data, designs etc from the shaheen program and make a SLV using the system... which will also be a ICBM. because thats what a ICBM is lol...if you can just put a warhead in orbit and make it land anywhere on earth...thats a ICBM for you.

    Yes Shaheen-II, atleast, is a two-stage missile using a solid-propellant. There have been news that another missile with 3000+ Km is in R & D at the moment so I guess we'll just have to wait and see what happens given the secretive nature in which Pakistan carries out its military R & D.

    Main issue is that we have gained and tested the ability to build multi-stage rockets.
    Once seperation process is fully develeopped and under controll, we can proceed to extend the range.
    Indeed, we're working on Tipu wich will have a 3000+ range. :)
