In 1985, Pakistan crossed the threshold of weapons-grade uranium production, and by 1986 it is thought to have produced enough fissile material for a nuclear weapon. Pakistan continued advancing its uranium enrichment program, and according to Pakistani sources, the nation acquired the ability to carry out a nuclear explosion in 1987.
Nuclear Tests
28 May Pakistan Goes Nuclear/ Youm-e-Takbeer is celebrated to remember the time when Pakistan became nuclear state , On May 28, 1998 Pakistan announced that it had successfully conducted five nuclear tests. The Pakistani Atomic Energy Commission reported that the five nuclear tests conducted on May 28 generated a seismic signal of 5.0 on the Richter scale, with a total yield of up to 40 KT (equivalent TNT). Dr. A.Q. Khan claimed that one device was a boosted fission device and that the other four were sub-kiloton nuclear devices.On May 30, 1998 Pakistan tested one more nuclear warhead with a reported yield of 12 kilotons. The tests were conducted at Balochistan, bringing the total number of claimed tests to six. It has also been claimed by Pakistani sources that at least one additional device, initially planned for detonation on 30 May 1998, remained emplaced underground ready for detonation.
Pakistani claims concerning the number and yields of their underground tests cannot be independently confirmed by seismic means, and several sources, such as theSouthern Arizona Seismic Observatory have reported lower yields than those claimed by Pakistan. Indian sources have also suggested that as few as two weapons were actually detonated, each with yields considerably lower than claimed by Pakistan. However, seismic data showed at least two and possibly a third, much smaller, test in the initial round of tests at the Ras Koh range. The single test on 30 May provided a clear seismic signal.
DEVICE | DATE | YIELD [announced] | YIELD [estimated] |
[boosted device?] | 28 May 1998 | 25-36 kiloton | total 9-12 kiloton |
Fission device | 28 May 1998 | 12 kiloton | |
Low-yield device | 28 May 1998 | sub-kiloton | – |
Low-yield device | 28 May 1998 | sub-kiloton | – |
Low-yield device | 28 May 1998 | sub-kiloton | – |
Fission device | 30 May 1998 | 12 kiloton | 4-6 kiloton |
Fission device | not detonated | 12 kiloton | – |
This table lists the nuclear tests that Pakistan claims to have carried out in May 1998 as well as the announced yields. Other sources have reported lower yields than those claimed by Pakistan. The Southern Arizona Seismic Observatory reports that the total seismic yield for the May 28th tests was 9-12 kilotons and that the yield for the May 30th tests was 4-6 kilotons. |
According to a preliminary analysis conducted at Los Alamos National Laboratory, material released into the atmosphere during an underground nuclear test by Pakistan in May 1998 contained low levels of weapons-grade plutonium. The significance of the Los Alamos finding was that Pakistan had either imported or produced plutonium undetected by the US intelligence community. But Lawrence Livermore National Laboratory and other agencies later contested the accuracy of this finding.
These tests came slightly more than two weeks after India carried out five nuclear tests of its own on May 11 and 13 and after many warnings by Pakistani officials that they would respond to India.
Pakistan’s nuclear tests were followed by the February 1999 Lahore Agreements between Prime Ministers Vajpayee and Sharif. The agreements included confidence building measures such as advance notice of ballistic missile testing and a continuation of their unilateral moratoria on nuclear testing. But diplomatic advances made that year were undermined by Pakistan’s incursion into Kargil. Under US diplomatic pressure, Prime Minister Sharif withdrew his troops, but lost power in October 1999 due to a military coup in which Gen. Pervez Musharraf took over.
Nuclear Arsenal
The Natural Resources Defense Council (NRDC) estimates that Pakistan has built 24-48 HEU-based nuclear warheads, and Carnegie reports that they have produced 585-800 kg of HEU, enough for 30-55 weapons. Pakistan’s nuclear warheads are based on an implosion design that uses a solid core of highly enriched uranium and requires an estimated 15-20 kg of material per warhead. According to Carnegie, Pakistan has also produced a small but unknown quantity of weapons grade plutonium, which is sufficient for an estimated 3-5 nuclear weapons.Pakistani authorities claim that their nuclear weapons are not assembled. They maintain that the fissile cores are stored separately from the non-nuclear explosives packages, and that the warheads are stored separately from the delivery systems. In a 2001 report, the Defense Department contends that “Islamabad’s nuclear weapons are probably stored in component form” and that “Pakistan probably could assemble the weapons fairly quickly.” However, no one has been able to ascertain the validity of Pakistan’s assurances about their nuclear weapons security.
Pakistan’s reliance primarily on HEU makes its fissile materials particularly vulnerable to diversion. HEU can be used in a relatively simple gun-barrel-type design, which could be within the means of non-state actors that intend to assemble a crude nuclear weapon.
The terrorist attacks on September 11th raised concerns about the security of Pakistan’s nuclear arsenal. According to press reports, within two days of the attacks, Pakistan’s military began relocating nuclear weapons components to six new secret locations. Shortly thereafter, Gen. Pervez Musharraf fired his intelligence chief and other officers and detained several suspected retired nuclear weapons scientists, in an attempt to root out extremist elements that posed a potential threat to Pakistan’s nuclear arsenal.
Concerns have also been raised about Pakistan as a proliferant of nuclear materials and expertise. In November, 2002, shortly after North Korea admitted to pursuing a nuclear weapons program, the press reported allegations that Pakistan had provided assistance in the development of its uranium enrichment program in exchange for North Korean missile technologies.
