The Hatf 5 "Ghauri" (Urdu: غوری) is a medium-range ballistic missile (MRBM) developed by Khan Research Laboratories of Pakistan. The missile uses a single stage liquid fuel rocket motor to carry a payload of 700 kg to a range of 1,500 km. Two variants of the Ghauri were produced under the Pakistani missile research and development program and the development of a third was cancelled. The Ghauri-II uses increased motor assembly length and improved propellants for an increased range of 2,300 km (1,400 mi).
The Hatf 5 is believed to be based on North Korea's Rodong 1 (also known as Nodong 1) design. According to a Pakistani analyst the original design was flawed and the missile burned up on re-entry during its first test flight. The missile system eventually entered service after being heavily re-engineered by Pakistan's NESCOM and National Development Complex research and development organisations. According to the Federation of Atomic Scientists the Hatf 5 Ghauri is believed to inherit a warhead spin-up mechanism from the Nodong 1). It is stated that this feature could improve accuracy up to 190 m CEP, although this is still debatable. The mechanism involved using steering vanes to spin the missile after 100 seconds of flight time. After 110 seconds the rocket motor stops and the warhead separates from the rocket motor. The warhead then enters a more stable re-entry trajectory due to the spinning motion. Warhead accuracy would be further enhanced if the Ghauri's inertial navigation system is capable of being updated by GPS satellite signals.
Liquid fuel ballistic missiles are incapable of storing fuel for any long period of time. The Ghauri requires refuelling for several hours before launch and this makes it vulnerable to a first strike. It is believed that this is why Pakistan has not pursued liquid fuelled missiles other than the Ghauri and Ghauri 2. It also makes it less likely that the Hatf 5 missiles in Pakistani service would be armed with a nuclear warheads. Although it has been stated that it is capable of being loaded with "all types" of warheads.
Pakistan's latest solid-fuelled Shaheen 1A is believed to be an alternate missile system for the Hatf 5 Ghauri. However it has been stated that the Ghauri has advantages in lower cost than solid fuel missiles. This is advantageous when testing launch and control systems. It has been speculated that the Hatf 5 design may serve as a starting point for a Pakistani space launch vehicle.
The Ghauri was first test-fired on 6 April 1998 from the Tilla Test-firing Range near Malute, Jhelum, about 76 miles south of the capital Islamabad. It was fired from a mobile launcher and travelled 1,100 km (680 mi) in a flight lasting 9 minutes and 58 seconds.
At the time it was stated that the missile hit its designated target in the desert of Balochistan. It has since been revealed that this first test was not a success because the missile burned up during the re-entry phase of its flight.
The missile has since been tested in December 2010  and November 2012. The November 2012 launch was performed by a Strategic Missile Group of the Army Strategic Force Command. The test-flight was monitored by the new Strategic Command and Control Support System (SCCSS) and is believed to have been geared towards testing the SCCSS rather than the missile itself.
