In later years, some funding for the continuation of the nuclear development programme came from the large British Pakistani population. In December 1972, Science Advisor to the President, Dr. Abdus Salam had called theoretical physicists from ICTP to report of Munir Ahmad Khan, Chairman of Pakistan Atomic Energy Commission. This marked the beginning of the "Theoretical Physics Group" (TPG). Later, Pakistani theoretical physicists at Institute of Physics of Quaid-e-Azam University also joined the TPG headed by Salam. The TPG, in PAEC, was assigned to took research in the development of nuclear weapon devices, and it had directly reported to Abdus Salam. Professor Salam also had done the groundbreaking work of the "Theoretical Physics Group", which was initially headed by Salam until in 1974 when he left the country in protest. On other side, Munir Ahmad Khan began to work on ingenious development of nuclear fuel cycle and the weapons programme. Munir Ahmad Khan, with his life long friend Abdus Salam, had done a groundbreaking work in the nuclear development, and after Salam's departure from Pakistan, scientists and engineers who were researching under Salam, began to report to directly to Munir Ahmad Khan. In 1974, Munir Ahmad Khan, days after Operation Smiling Buddha

, launched the extensive plutonium reprocessing and uranium enrichment programme, and the research facilities were expanded throughout the country.

In 1965, amidst skirmishes that led up to the Indo-Pakistan War of 1965 Zulfikar Ali Bhutto announced:

Through the late 1970s, Pakistan's program acquired sensitive uranium enrichment technology and expertise. The 1975 arrival of Dr. Abdul Qadeer Khan considerably advanced these efforts. Dr. Khan is a German-trained metallurgist who brought with him knowledge of gas centrifuge technologies that he had through his position at the classified URENCO uranium enrichment plant in the Netherlands. He was put in charge of building, equipping and operating Pakistan's Kahuta facility, which was established in 1976. Under Khan's direction, Pakistan employed an extensive clandestine network in order to obtain the necessary materials and technology for its developing uranium enrichment capabilities.

Modernisation and expansion

Pakistan is increasing its capacity to produce plutonium at its Khushab nuclear facility, a Washington-based science think tank has reported. Estimated Pakistani nuclear weapons is probably in the neighborhood of more than 200 by the end of 2009. “The sixth Pakistani nuclear test (May 30, 1998) at Kharan was a successful test of a sophisticated, compact, but powerful bomb designed to be carried by missiles. The Pakistanis are believed to be spiking their plutonium based nuclear weapons with tritium

Only a few grams of tritium can result in an increase of the explosive yield by 300% to 400%.” Citing new satellite images of the facility, the Institute for Science and International Security (ISIS) said the imagery suggests construction of the second Khushab reactor is “likely finished and that the roof beams are being placed on top of the third Khushab reactor hall”.

In late 2006, the Institute for Science and International Security released intelligence reports and imagery showing the construction of a new plutonium reactor at the Khushab nuclear site. The reactor is deemed to be large enough to produce enough plutonium to facilitate the creation of as many as "40 to 50 nuclear weapons a year."
The New York Times carried the story with the insight that this would be Pakistan's third plutonium reactor, signaling a shift to dual-stream development, with Plutonium-based devices supplementing the nation's existing HEU stream to atomic warheads.

 estimated a stockpile of approximately 50 weapons. By contrast, in 2000, U.S. military and intelligence sources estimated that Pakistan's nuclear arsenal may be as large as 100 warheads.

The actual size of Pakistan's nuclear stockpile is hard for experts to gauge owing to the extreme secrecy which surrounds the program in Pakistan. However, in 2007, retired Pakistan Army's Brigadier-General Feroz Khan, previously second in command at the Strategic Arms Division of Pakistans' Military told a Pakistani newspaper that Pakistan had "about 80 to 120 genuine warheads."

Pakistan tested plutonium capability in the sixth nuclear test, codename Chagai-II, on 30 May 1998 at Kharan Desert. In this test the most compact and sophisticated design, made to be carried by small delivery vehicles such as MIRV and cruise missile

s, was tested.

The critical mass of a bare mass sphere of 90% enriched uranium-235 is 52 kg. Correspondingly, the critical mass of a bare mass sphere of plutonium-239 is 8–10 kg. The bomb that destroyed Hiroshima used 60 kg of U-235 while the Nagasaki Pu bomb used only 6 kg of Pu-239. Since all Pakistani bomb designs are implosion-type weapons, they will typically use between 15–25 kg of U-235 for their cores. Reducing the amount of U-235 in cores from 60 kg in gun-type devices to 25 kg in implosion devices is only possible by using good neutron reflector/tamper material such as beryllium metal, which increases the weight of the bomb. And the uranium, like plutonium, is only usable in the core of a bomb in metallic form.

However, only 2–4 kg of plutonium is needed for the same device that would need 20–25 kg of U-235. Additionally, a few grams of tritium (a by-product of plutonium production reactors and thermonuclear fuel) can increase the overall yield of the bombs by a factor of three to four. “The sixth Pakistan nuclear test, codename Chagai-II, (May 30, 1998) at Kharan Desert was a successful test of a sophisticated, compact, but powerful bomb designed to be carried by missiles. The Pakistanis are believed to be spiking their plutonium based nuclear weapons with tritium. Only a few grams of tritium can result in an increase of the explosive yield by 300% to 400%.”

A whole range and variety of weapons using Pu-239 can be easily built, both for aircraft delivery and especially for missiles (in which U-235 cannot be used). So if Pakistan wants to be a nuclear power with an operational deterrent capability, both first and second strike, based on assured strike platforms like ballistic and cruise missiles (unlike aircraft), the only solution is with plutonium, which has been the first choice of every country that built a nuclear arsenal.

As for Pakistan's plutonium capability, it has always been there, from the early 1970s onwards. However, there were only two logistic problems faced by PAEC. One was that Pakistan did not want to be an irresponsible state and the PAEC did not divert spent fuel from the safeguarded KANUPP for reprocessing at the New Labs. This was enough to build a whole arsenal of nuclear weapons straight away. The PAEC built its own plutonium and tritium production reactor at Khushab, known as Khushab-I reactor, beginning in 1985. The second one was allocation of resources.

Ultra-centrifugation for obtaining U-235 cannot be done simply by putting natural uranium through the centrifuges. It requires the complete mastery over the front end of the nuclear fuel cycle, beginning at uranium mining and refining, production of uranium ore or yellow cake, conversion of ore into uranium dioxide UO2 (which is used to make nuclear fuel for natural uranium reactors like Khushab and KANUPP), conversion of UO2 into uranium tetrafluoride UF4 and then into the feedstock for enrichment (UF6).

The complete mastery of fluorine chemistry and production of highly toxic and corrosive hydrofluoric acid and other fluorine compounds is required. The UF6 is pumped into the centrifuges for enrichment. The process is then repeated in reverse until UF4 is produced, leading to the production of uranium metal, the form in which U-235 is used in a bomb.

It is estimated that there are approximately 10,000-20,000 centrifuges in Kahuta. This means that with P2 machines, they would be producing between 75–100 kg of HEU since 1986, when full production of weapons-grade HEU began. Also the production of HEU was voluntarily capped by Pakistan between 1991 and 1997, and the five nuclear tests of 28 May 1998 also consumed HEU. So it is safe to assume that between 1986 and 2005 (prior to the 2005 earthquake), KRL produced 1500 kg of HEU. Accounting for losses in the production of weapons, it can be assumed that each weapon would need 20 kg of HEU; sufficient for 75 bombs as in 2005.

Pakistan's first nuclear tests were made in May 1998, when six warheads were tested under codename Chagai-I

 and Chagai-II. It is reported that the yields from these tests were 12 kt, 30 to 36 kt and four low-yield (below 1 kt) tests. From these tests Pakistan can be estimated to have developed operational warheads of 20 to 25 kt and 150 kt in the shape of low weight compact designs and may have 300–500 kt large-size warheads. The low-yield weapons are probably in nuclear bombs carried on fighter-bomber

 capability. Pakistan has been dealing with efforts to develop new weapons and at the same time, have a strategy for surviving a nuclear war. Pakistan has built hard and deeply buried storage and launch facilities to retain a second strike capability in a nuclear war.

It was confirmed that Pakistan has built Soviet-style road-mobile missiles, state-of-the-art air defences around strategic sites, and other concealment measures. In 1998, Pakistan had 'at least six secret locations' and since then it is believed Pakistan may have many more such secret sites. In 2008, the United States admitted that it did not know where all of Pakistan’s nuclear sites are located. Pakistani defence officials have continued to rebuff and deflect American requests for more details about the location and security of the country’s nuclear sites.

MIRV capability

Pakistani engineers are also said to be in the advance stages of developing MIRV technology for its missiles. This would allow the military to fit several warheads on the same ballistic missile and then launch them at separate targets.
