Key takeaways

  • Ghauri (missile) belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Ghauri (missile) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Ghauri (missile) from memory before moving on to harder problems.

Reference excerpt

The Ghauri–I (Urdu: غوری-ا; military designation: Hatf–V, Trans.: Target-5) is a land-based medium-range ballistic missile, in current service with the strategic command of the Pakistan Army. Influenced from the propellent design of Nodong-1 of North Korea, its extensive modification, warhead design and assembly, and engineering of its control system took place in Khan Research Laboratories (KRL) in 1994–2001 with an objective of developing an electronic system that uses a single stage liquid fuel rocket motor to carry a payload of 700 kg to a range of 1,500 km. This range is applicable to address Pakistan's nuclear deterrence against India, if not all of India. Codenamed as Ghauri, the missile was developed in as part of the secretive Hatf program that started in 1987. The program later evolved into the development of now cancelled Ghauri-III and the Ghauri-II which uses increased motor assembly length and improved propellants for an increased range of 2,300 km (1,400 mi). The Ghauri is deployed in the ASFC with using the "Hatf-V" military designation which means "Target-5".

History

Codename

Upon its development, the missile was named after the 12th century Sultan Shahabuddin Ghauri, by a senior scientist who worked on the program with a keen interest in medieval history— this codename was approved by the Prime Minister Benazir Bhutto in 1994. Sultan Muhammad Ghauri, who successfully campaigned in the northwestern region of India between 1176 and 1182, but was defeated in his first battle in northern India by Indian King Prithviraj Chauhan; but Ghauri returned in June 1192 when he defeated Prithviraj. He captured Delhi in 1199, but established his kingdom formally in 1206. However, the JS HQ has officially codenamed the missile "Hatf–5 (Ghauri–I); the Hatf codename originates from the name of the sword or lance of Muhammad.

Development According to the American intelligence estimates in 1999, the Ghauri–I is influenced and its design development is based on the Nodong-1 (a copy of former Soviet Scud) missile of North Korea. Development of Ghauri was a source of contention and controversy between Pakistan and the United States with Clinton administration publicly leveling serious allegations on the Benazir Bhutto's federal ministry of transferring nuclear technology in 1996. Later, Japan intervened in this matter, pressured Sharif administration to cut ties with North Korea in 1999. There were many conflicting stories until 2012 when official documentation was published in a text about North Korea's contribution. Before 2012, many in Pakistan and the United States had alleged that the technology transfer took place in 1993 in return of the instructions on enrichment methods for uranium Not much has been publicized as controversy surrounds the claim that North Korean nuclear program was well advanced before the instructions on enrichment methods uranium were provided. It is now well documented by the Pakistani military admissions that the finance ministry under Benazir Bhutto's administration had paid stacks of cash through its State Bank to North Korea as President Kim Il Sung was only interested in monetary values rather than technological barter trade. After the transaction, the North Korean scientists and engineers were then sent to Pakistan to teach aerospace engineering at Pakistani universities in 1993.

Design and engineering Much of the engineering data for Ghauri comes from the former Soviet Scud technology, compiled by the American think tanks. The mechanism of North Korean's Nodong-1 is copied from the Soviet Scud specification to compare with Ghauri. The Khan Research Laboratories designed the warhead for the Ghauri and no official information is available due to Pakistani government classifying its data as Top Secret (TS confidentiality), aside from speculations from independent and outside sources. According to the official Pakistani military reports, the original design of the missile was flawed and the missile's frontal conic nose section material burned up due to generated shock waves and hypersonic effect on re-entry during its first test flight in 1998. High stress and high temperature shift caused the material to melt during the re-entry while its vintage electronic systems, engine system, and propellant had to be replaced. The first design of Ghauri was built under the watchful guidance of North Koreans based on their specification but the Koreans were immediately sent back by Sharif administration after the failure of the system was identified. Eventually, the conic nose section was redesigned by rounding the cone which allowed the missile to travel from subsonic flow to supersonic flow. The KRL, now forced to collaborate with NESCOM (NDC), engaged in heavy reengineering of much of its controls and electronics system. Due to lack of experience at KRL it took years of expensive trials and errors to make Ghauri nuclear weapons delivery capable, and it was not until 2003 when Ghauri was finally capable of military deployment.

Prospect of civilian space program The liquid fuel systems are incapable of storing fuel for any long period of time– the Ghauri–I requires fueling for several hours before launch, making it vulnerable to a first strike the standing enemy. Noting this constraint, the Pakistani war strategists have not pursued liquid fuel systems other than the Ghauri–I and Ghauri-II. The Ghauri-I is a nuclear weapon-delivery capable missile which has been stated by the Pakistani military that it is also capable of being loaded with "all types" of warheads. Contrast to the Shaheen program that went under the joint conjecture of Pakistan's Air Force and the Army, the Ghauri program was designed for the Pakistan Army which was setting to accuracy goal for a highly accurate missile designed to strike high-value targets. In 2004, there was a strong lobby within the engineering community to make Ghauri feasible as a launch vehicle for satellites.

Worked examples

Example 1 — a first encounter with Ghauri (missile)

Start with the simplest possible case. Write down what Ghauri (missile) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ghauri (missile) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ghauri (missile) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ghauri (missile)

In research
Ghauri (missile) appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Ghauri (missile) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Ghauri (missile) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1998 in spaceflight, 2003 in spaceflight, Medium-range ballistic missiles of Pakistan, so understanding it makes those chapters shorter.
In everyday life
Look for Ghauri (missile) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
