Biography

[edit]

Early life and education

[edit]

Samar Mubarakmand was born in Rawalpindi in the Punjab Province of British India (now in Punjab, Pakistan) on 17 September 1942, into a Muslim family from Hoshiarpur (now in Punjab, India).[5] He was educated in Lahore and matriculated from St. Anthony's High School in 1956.[5] After passing university entrance examinations, he enrolled at Government College University (GCU), where he studied physics under Tahir Hussain.[7] In 1960, he graduated with a Bachelor of Science (BSc) in physics, concentrating in experimental physics with a minor in mathematics.[8] During college, Mubarakmand was a swimmer and represented GCU at the National Games of Pakistan.[8]

He researched experimental physics under Hussain and built an experimental apparatus for his master's thesis.[8] His thesis included work on gamma‑ray spectrometry, and he conducted an experiment witnessed by nuclear physicist Denys Wilkinson as part of his master's programme.[8] Wilkinson invited Mubarakmand to visit the University of Oxford in the United Kingdom to pursue further study in experimental physics.[8]

In 1962, Mubarakmand received an MSc in physics after completing his thesis, Construction of a Gamma-Ray Spectrometer.[2] The same year, he joined the Pakistan Atomic Energy Commission (PAEC) and received a scholarship to study at Oxford, where he joined Wilkinson's group.[8] Mubarakmand helped prepare and commission a 22‑million‑volt particle accelerator. He also studied linear accelerators and, after returning to Pakistan, built one.[9] Besides his studies, he played cricket as a fast bowler for the Oxford University Cricket Club.[8] In 1966, he completed his doctoral thesis under Wilkinson and was awarded a Doctor of Philosophy (DPhil) in experimental nuclear physics.[10][11][12]

Pakistan Atomic Energy Commission (PAEC)

Upon his return to Pakistan, Mubarakmand joined the Pakistan Atomic Energy Commission (PAEC). Drawing on his experience with high‑energy accelerators, he converted a neutron generator available at PAEC to study nuclear structure and fast neutron scattering. In 1974, he completed research on fast neutron‑induced reactions and developed experimental techniques for neutron spectroscopy. This work resulted in several publications in the journals Nuclear Physics and Nuclear Instruments and Methods (North‑Holland).[13]

From 1974 to 1977, he served on temporary attachment as director of the Center for Advanced Studies in Physics (CASP) at Government College University, Lahore. During this period, he developed an interest in applications of solid‑state track detectors. In 1976 he presented this work at an international conference at the Max Planck Institute in Munich.[14][15]

From 1977 to 1980, Mubarakmand conducted research on the use of lasers and on isotope separation in sulfur hexafluoride. He also studied methods of transmitting signals through optical fibers to reduce electromagnetic interference. These studies formed part of the broader development of fiber‑optic technology in Pakistan during that period.[16]

1971 War and Atomic Bomb Project

[edit]

In the 1980s, PAEC was busy developing several designs of nuclear devices and decided that these designs would have to be ratified through cold tests. Mubarakmand was known for his expertise in fast neutron spectrometry.[citation needed]

During his doctoral studies on nuclear structure at the University of Oxford, Mubarakmand developed and refined a technique for the spectroscopy of fast neutrons released during the nuclear reactions under investigation. This technique has direct applications in conducting cold tests of nuclear devices.

Munir Khan, chairman of the PAEC, selected Mubarakmand as the first choice for head of the Diagnostic Group.[17]

My eyes were set on the mountain in which the test was to be conducted. I experienced a halt in my heartbeat on seeing nothing happening after 32 seconds. But all of a sudden it was a big jolt! We had triumphed....!

— Samar Mubarakmand's describing the blast yield in 1998., Cited source[18]

Several designs of nuclear devices were developed, and their performance was assured with high confidence through cold testing. Each test involved the detection and measurement of fast neutrons emitted in brief, intense bursts lasting less than a microsecond. All available nuclear devices that had been designed and developed were subsequently cold tested and qualified. In addition, the Diagnostic Group successfully carried out the important task of designing and manufacturing a neutron trigger source[19] based on fusion reactions. This neutron source would trigger a nuclear device in a hot test.

From 1991 to 1994, Mubarakmand was promoted to head of the Directorate of Technical Development (DTD) where he supervised and modernized work methods. Within three years, smaller nuclear devices with updated specifications were developed to meet the diverse requirements of Pakistan’s fighter aircraft and various upcoming delivery systems. All designs were validated through cold testing by his former diagnostic team.

After three years as Director DTD, Mubarakmand was promoted to Director General DTD in 1994. In 1995, he was given the responsibility of Member Technical PAEC, which he held till the year 2000. During the five-year tenure, Mubarakmand, apart from looking after the classified side of the Technical Program of PAEC, also became responsible for the optimal functioning of the centers of Nuclear Medicine, Agriculture, PINSTECH and New Labs. At New Labs, Mubarakmand and a team of PAEC’s Scientists and Engineers were able to establish and commission Pakistan’s first reprocessing plant for burnt reactor fuel. This led to the production of metallic plutonium at the facility in the year 2000.[20]

Several areas were visited and studied with the help of senior geologists of the PAEC. Chairman Ishfaq Ahmed eventually selected the Chaghai site for conducting Pakistan’s nuclear hot tests. Mubarakmand supervised the installation of diagnostic equipment and other nuclear testing safety infrastructure.

In 2005, Mubarakmand eulogized his memories in an interview with Hamid Mir's Capital Talk television show and said:

"I visited the first weapon-testing laboratories (WTL) at (Chagai District) for the first time in 1981.... When the science experiments were to be conducted, our science teams went there on 20th May, and again on 28th May, in the early morning, the WTL iron-steel tunnels were (electronically) plugged in and the preparation for the tests' experiments were complete, and on 28th May, around 15:15hrs, was the time selected for testings. So, at that time, at around 14:45hrs, some of our high profiled guests arrived to witness the (science) experiments that were soon to be tests, and Qadeer Khan was also one of them.... It was the first visit of his life to any of Chagai's Weapon-testing laboratories. (Abdul Qadeer) came at the invitation of the Chairman of the PAEC, Ishfaq Ahmad, and (Abdul Qadeer) arrived 15 minutes prior to the (science) experiments that were to be conducted..."

— Samar Mubarakmand, commenting on Abdul Qadeer Khan's role in atomic bomb project, [21][22]

Recalling Munir Ahmad Khan and the PAEC's role in relation to the atomic bomb project priority dispute, Mubarakmand later said that:

"As many as nineteen steps were involved in the making of a nuclear weapon ranging from exploration of uranium to the finished device and its trigger mechanism. The technological and manpower infrastructure for eighteen out of these nineteen steps were provided by PAEC under the leadership of Munir Ahmad Khan who led it for nearly two decades from 1972 to 1991. Today all the major key scientific organizations linked to the country's security like PAEC, the Kahuta Research Labs and the strategic production complex were run and operated by Pakistani professionals produced by the policies of PAEC both under him and Usmani of producing indigenous trained manpower. Pakistan's nuclear capability was confirmed the day in 1983 when PAEC carried out cold nuclear tests under the guidance and stewardship of Munir Ahmad Khan. The tests however, were not publicly announced because of the international environment of stiff sanctions against countries, which sought to acquire nuclear capability...."

Pakistan’s missile program

[edit]

In the 1990s, Mubarakmand worked to advance the space program and led a team of engineers that developed the Shaheen-I missile.[24] He was the founding director of the National Defence Complex (NDC), which initiated work on Shaheen‑I and garnered support for the program.[25] Funding for the program was secured by the military, and Mubarakmand oversaw the development of the solid-fuel rocket booster.[25]

Initiated in 1987 by the Pakistan Ministry of Defence—in response to India's Integrated Guided Missile Development Programme—Pakistan’s spin‑off missile program was further pursued in 1993 under Prime Minister Benazir Bhutto. The Shaheen‑I missile was test‑fired in 1999 by a team of engineers led by Mubarakmand.[25] Subsequently, Shaheen-II and Shaheen-III were test‑fired, with ranges of 2,000 km and 2,750 km, respectively.[26]

Other strategic systems, including Babur and Ghaznavi, were also developed by teams he led.[27] Development of the Babur cruise missile (range ~700 km)[28] proceeded in the same period; multiple boost‑phase and flight‑phase tests evaluated performance and potential roles in national defense strategy. Mubarakmand retired from the NESCOM in November 2007.

In 2008, he joined the Planning Commission of Pakistan, where he advocated for peaceful uses of the space program. In 2009, he announced work on Paksat-1R, the country's first geostationary satellite, which was launched in 2011.[29] The satellite was described as supporting monitoring of agriculture, mineral resources, and weather conditions; he also stated that there were sufficient funds for defence, nuclear, and space programs.[30] It was launched in 2011 from the Xichang Satellite Launch Centre in China.[31] His relations with Dr Abdul Qadeer Khan were often tense over scientific issues.

Thar Coal Project

[edit]
Main articles: Thar coalfield and Reko Diq

In 2013, Mubarakmand assisted the Provincial Government of Balochistan in mineral extraction.[32] He lobbied heavily for the implementation of the Thar coal project initiated by the Provincial Government of Sindh despite strong public criticism by Abdul Qadeer Khan. In 2015, a breakthrough in the Thar coal project was reported by the media.[6] According to Mubarakmand, the Thar coal reserves have been projected to supply power for several decades, subject to development and policy implementation. When speaking to a large crowd at Cadet College Fateh Jang, he said that he had developed a solution to the growing power outage and was now waiting for the government to put it into action. [1]

Reko Diq Copper Gold Project

[edit]
Main article: Reko Diq case

In December 2020, the Tethyan Cooper Company (TCC) approached the High Court of Justice in the British Virgin Islands for the enforcement of the $5.97 billion award against Pakistan by the International Centre for Settlement of Investment Disputes (ICSID) in the Reko Diq case.[33]

A senior official revealed that the "misstatement" of Mubarakmand before the Supreme Court tribunal, in which he in 2011 had claimed that the Reko Diq gold mines would fetch Pakistan around $2.5 billion annually, was one of the main reasons behind the Supreme Court's decision on 7 January 2013. On that date, a three-member bench of the apex court, headed by then Chief Justice Iftikhar Muhammad Chaudhry, declared the Chagai Hills Exploration Joint Venture Agreement (Chejva) "illegal, void" and non-binding, causing ICSID to slap a heavy penalty on Pakistan. Mubarakmand projected that Reko Diq and other reserves could generate up to $131 billion over the mine’s lifetime.[34] The tribunal relied on his statement.[35] [36] [37][33]

State honours

[edit]

Mubarakmand has been conferred with state honors for his services to the country by the Government of Pakistan. He is the recipient of the Sitara-e-Imtiaz (1992); Hilal-e-Imtiaz (1998); and the Nishan-e-Imtiaz (2003), which is the highest civil honor of Pakistan.[5][38] Additionally, he is a Fellow of the Pakistan Academy of Sciences (PAS), inducted by Ishfaq Ahmad in 2000.[5][39]

His contributions earned him prestigious national honors, including the Nishan-i-Imtiaz, and recognition as a fellow of the Pakistan Academy of Sciences, underscoring his role in bolstering 's strategic autonomy amid regional security pressures.

Early Life and Education

Formative Years and Academic Background

Samar Mubarakmand was born on 17 September 1942 in , Province of British India (present-day ), to a Punjabi Muslim family originally from in . Little is documented regarding specific family influences on his early interests, though he pursued education in following initial schooling there. He completed his elementary and intermediate education in before enrolling at Government College University (GCU), Lahore, where he studied physics under notable instructors such as . In 1962, Mubarakmand earned a degree in physics from GCU, affiliated with the , and received the Academic Roll of Honour for his performance. That same year, he secured a doctoral scholarship to the , where he conducted research in under Shaukat Hameed Khan, focusing on and the dynamical theory of . His doctoral thesis featured detailed experimental work on gamma ray spectrometry, including an demonstration observed by nuclear physicist Denys Wilkinson, leading to his PhD in the mid-1960s.

Scientific Career Beginnings

Initial Research and PAEC Involvement

Samar Mubarakmand joined the (PAEC) in 1966 after completing his PhD in at the . There, he initiated his professional research career, concentrating on nuclear instrumentation and experiments. Mubarakmand's early work emphasized charged particle accelerators and spectroscopy, fields informed by his doctoral studies on and the dynamical theory of gamma spectroscopy. Leveraging expertise from high-energy accelerator operations abroad, he adapted existing equipment, including generators, for investigations into nuclear structure and fast cross-section measurements at PAEC facilities. By 1978, Mubarakmand directed the assembly of a charged particle linear accelerator and a dedicated neutron generator at the Pakistan Institute of Nuclear Science and Technology (PINSTECH), a primary PAEC research laboratory in Rawalpindi. These instruments advanced PAEC's foundational capabilities in experimental nuclear physics, enabling precise studies of particle interactions and spectroscopic analyses without reliance on external infrastructure.

Role in Nuclear Weapons Development

Post-1971 War Initiatives

The 1971 Indo-Pakistani War culminated in Pakistan's surrender on December 16, 1971, leading to the dismemberment of the country with the secession of as and the capture of over 90,000 Pakistani prisoners of war by Indian forces. This outcome starkly revealed Pakistan's conventional military inferiority to , which fielded approximately 500,000 troops against Pakistan's 365,000, compounded by India's alliances and territorial advantages. The war's lessons—demonstrating repeated vulnerability to a neighbor with superior manpower, resources, and aggressive intent—drove a strategic imperative for nuclear deterrence as the only viable counter to existential threats, overriding earlier PAEC emphases on civilian applications like power generation. In the immediate aftermath, Prime Minister authorized PAEC on January 20, 1972, to initiate nuclear weapons development, marking a decisive shift toward weaponization feasibility studies under Munir Ahmad Khan's leadership. This pivot was grounded in the recognition that nuclear parity could causally prevent future invasions, given India's post-war nuclear pursuits and conventional edge, rather than deferring to global non-proliferation pressures from entities like the , which imposed sanctions but failed to address the asymmetry. PAEC teams began theoretical assessments of utilization and device physics, prioritizing self-reliant sovereignty amid regional instability. Samar Mubarakmand, having joined PAEC in the early , was reassigned in January 1972 to Ishfaq Ahmad's Division, where he focused on core physics computations critical to evaluating implosion dynamics and neutronics for potential devices. His contributions helped quantify the technical viability of a plutonium-based approach, drawing on empirical reactor data from facilities like PARR-1, operational since , to inform the program's deterrence rationale without reliance on unproven foreign aid. This early involvement underscored PAEC's internal capacity-building, as external sourcing risks were deemed incompatible with strategic autonomy post-1971.

Atomic Bomb Project Contributions

Mubarakmand directed the Fast Neutron Physics Group (FNPG), formed in 1974 under the (PAEC) on the advice of , to investigate fast neutron interactions essential for the physics of implosion-type nuclear devices. This group focused on high-energy simulations using modified neutron generators and accelerators at PINSTECH to model fission chain reactions and compression dynamics required for reliable weapon initiation. His technical contributions emphasized nuclear diagnostics and applications for precise measurement of implosion symmetry and timing in weapon assembly processes. Mubarakmand's team integrated fiber optics and -based diagnostics to validate configurations, ensuring uniform core compression through empirical data from subcritical experiments. From 1983 onward, he oversaw the first series of cold tests—non-nuclear hydrodynamic simulations of implosion mechanisms—to confirm device reliability and precursors to , such as reduced assembly times and enhanced tamper efficiency via first-principles hydrodynamic modeling. These PAEC-led efforts prioritized verifiable milestones, including achieving simulated criticality thresholds in plutonium surrogates, to engineer robust systems independent of external designs.

Supervision of 1998 Chagai Tests

Samar Mubarakmand served as the on-site director for Pakistan's nuclear test operations in May 1998, personally overseeing the final assembly of five implosion-type fission devices emplaced in horizontal tunnels at the Ras Koh Hills test site in Balochistan's . The assembly process involved integrating cores with high-explosive lenses and diagnostic instrumentation under stringent security, culminating in simultaneous detonation on May 28 at 15:15 PKT during the series. Seismic recordings from global monitoring stations registered a body-wave magnitude of approximately , yielding empirical estimates of 8-12 kilotons total explosive power after against known test data from regional . On May 30, Mubarakmand directed the follow-up test, involving the detonation of a single low-yield device in a vertical shaft within the adjacent , approximately 50 kilometers southeast of the site. This operation confirmed the functionality of a compact intended for tactical applications, with Mubarakmand reporting a yield of 15-18 kilotons based on on-site measurements. Seismic data indicated a lower multi-kiloton output consistent with the device's boosted fission configuration. The successful execution of these underground tests under Mubarakmand's supervision empirically validated the indigenous designs developed through iterative cold testing and sub-kiloton hot tests, achieving Pakistan's threshold for operational nuclear capability. By demonstrating reliable detonation yields, the series established , directly offsetting India's tests earlier that month and restoring strategic parity amid Pakistan's conventional force disadvantages.

Missile and Aerospace Programs

Establishment of SUPARCO Collaborations

In 1987, Samar Mubarakmand spearheaded the launch of Pakistan's Missile Integration Programme under the auspices of the , establishing foundational collaborations between the (PAEC) and the Space and Upper Atmosphere Research Commission (SUPARCO) to adapt nuclear-derived technologies for development. This initiative integrated PAEC's advancements in solid-fuel propulsion—stemming from experimental and accelerator research—with SUPARCO's expertise in rocketry and sounding rockets, enabling the pursuit of indigenous solid-fuel systems for delivery vehicles. The program emphasized dual-use applications of space technologies, recognizing their potential to address gaps in conventional deterrence without reliance on foreign imports. Mubarakmand's oversight within PAEC focused on short- and medium-range ballistic missiles, including early iterations of the Hatf series, where SUPARCO contributed launch facilities and guidance know-how alongside PAEC's propellant innovations. These efforts prioritized domestic manufacturing of components, such as solid rocket boosters, to build self-sufficiency in propulsion systems amid geopolitical pressures, including India's parallel advancements that heightened regional asymmetries in standoff capabilities. By coordinating inter-agency resources, the collaborations laid the groundwork for scalable architectures, underscoring the strategic imperative of from civilian endeavors to defense applications for credible .

Key Missile Developments

Mubarakmand played a pivotal role in 's ballistic missile development, particularly as head of the National Development Complex, where he oversaw the establishment of indigenous capabilities in response to international export controls on missile technology. His experience in nuclear diagnostics informed advancements in re-entry vehicle design and guidance systems, enabling reliable payload delivery over extended ranges. Under his coordination, the Ghauri program achieved its first successful on April 6, 1998, demonstrating a range of approximately 1,100 km with an apogee of 350 km, marking a key step toward medium-range deterrence. In the Shaheen series, Mubarakmand served as chief project coordinator starting in 1995 and director from 1996, founding the to drive solid-fuel technology integration. His team developed solid boosters and engines for , culminating in operational deployment by the early 2000s with ranges exceeding 750 km. Subsequent advancements under his guidance included the test on March 9, 2004, which validated a full range of 2,500 km—though fired to 2,000 km to respect maritime limits—incorporating improved inertial guidance for precision targeting. These milestones underscored Pakistan's self-reliant progress, with flight tests confirming structural integrity and propulsion efficiency despite sanctions limiting foreign inputs.

Energy and Resource Exploration Projects

Thar Coal Mining Initiative

Samar Mubarakmand was appointed Chairman of the Board of Governors for the Project in the Thar coalfields in 2009, tasked with developing local technology for extracting energy from the region's vast deposits. Under his leadership, the initiative focused on (UCG) as a method to convert in-situ into for power generation, aiming to mitigate Pakistan's chronic energy shortages amid reliance on imported fuels. This approach was selected for its potential to bypass traditional challenges in the arid , where high water tables and remote location complicated surface extraction. The , spanning over 9,000 square kilometers, holds an estimated 175 billion tons of reserves, as assessed by the Geological Survey of Pakistan, representing one of the world's largest untapped deposits sufficient to fuel national electricity needs for centuries at current consumption rates. Mubarakmand's team targeted Block V for a pilot UCG operation, initiating exploratory drilling and gasification trials to produce combustible , with projections that even 1% of the reserves could generate a significant portion of 's power for decades, offering economic viability through low-cost domestic fuel over expensive imports. He advocated for UCG's technical merits, emphasizing its ability to yield for direct use in generators, potentially supplying over 100 megawatts initially and scaling to address the projected to persist without indigenous alternatives. Pilot efforts under Mubarakmand achieved initial successes, including the production of syngas via horizontal directional drilling and ignition processes, enabling brief electricity generation from on-site generators as proof-of-concept for UCG feasibility in Thar’s geological conditions. However, progress faced delays from technical hurdles such as inconsistent gas flow due to seam variability and aquifer interference, alongside funding constraints that slowed scaling from pilot to commercial phases, despite approvals aiming for operational status by late 2013. These challenges underscored the economic rationale of UCG for resource-poor , prioritizing gasification's lower capital costs over mining infrastructure, though experts noted risks of groundwater contamination and variable yield in lignite seams.

Reko Diq Copper-Gold Project

Samar Mubarakmand advocated for Pakistan to independently develop the copper-gold deposit in Balochistan's , arguing that the nation could leverage indigenous expertise akin to its nuclear program to extract resources without heavy reliance on foreign firms. In 2011, he testified before Pakistan's challenging the mining agreement with Tethyan Copper Company (TCC), a of Barrick Gold and , asserting that domestic technical capabilities sufficed for feasibility studies, extraction, and processing of the site's estimated 5.9 billion tonnes of ore grading 0.41% and containing significant reserves. His position emphasized state-led initiatives to maximize economic benefits, projecting substantial revenue for and development from the minerals, valued in recent feasibility studies at over $60 billion in and at prevailing prices. Mubarakmand's technical input included claims of prior success in resource projects, positioning him as a proponent for adapting nuclear and geophysical expertise to operations, such as and site evaluation. However, his opposition contributed to the Supreme Court's 2013 annulment of the TCC agreement, triggering under ICSID that imposed potential liabilities exceeding $5 billion on before a 2022 settlement revived the project with Barrick Gold holding 50% stake alongside federal and provincial shares. This highlighted development hurdles, including legal disputes delaying extraction and underscoring dependencies on foreign investment for capital-intensive infrastructure like and concentrators, despite the site's potential to generate $74 billion in over 37 years. While state-led extraction could mitigate foreign control risks, environmental challenges persist, such as in arid and tailings management for large-scale operations, potentially impacting local ecosystems and communities. Mubarakmand's prioritized national over expedited foreign partnerships, though subsequent resolutions favored collaborative models to overcome technical and financial barriers inherent to the project's scale.

Scientific Publications and Research Output

Major Works in Nuclear Physics

Mubarakmand's research in emphasized experimental approaches to and nuclear instrumentation, areas detailed in his academic training and subsequent work at the . His 1962 master's thesis, titled "Construction of a Gamma-Ray Spectrometer," described the design and assembly of an instrument for high-resolution analysis of gamma emissions from nuclear reactions, enabling precise identification of energy levels in atomic nuclei. This work laid groundwork for empirical validation of nuclear decay processes through direct measurement rather than purely theoretical models. At the , Mubarakmand's doctoral studies from the late 1960s focused on nuclear structure, incorporating dynamical theory of and Compton scattering effects to probe photon-nucleus interactions. These investigations contributed to improved diagnostics for reactions, emphasizing observable data from experiments to refine models of nuclear excitation and de-excitation. His broader research portfolio, as recognized by the Pakistan Academy of Sciences, encompassed , neutron polarization studies, and laser-produced plasmas, with applications to high-energy nuclear diagnostics. These efforts prioritized instrumental innovations for real-world nuclear measurements, influencing empirical methodologies in Pakistan's physics community over the 1970s to 1990s, though specific peer-reviewed outputs were often channeled through classified or institutional channels rather than international journals.

Honors, Awards, and Recognition

National and International Accolades

Samar Mubarakmand was awarded the Sitara-e-Imtiaz in 1992 for advancements in nuclear instrumentation and physics research. In 1998, following his leadership in the Chagai nuclear tests, he received the Hilal-e-Imtiaz recognizing contributions to national defense through nuclear capabilities. The , Pakistan's highest civilian honor, was bestowed upon him in 2003 for directing the missile development program that enhanced strategic deterrence. Mubarakmand was elected a Fellow of the Pakistan Academy of Sciences in 2003, acknowledging his expertise in nuclear structure and diagnostics. This fellowship highlights institutional recognition of his foundational work in physics applied to security technologies.

Controversies and Criticisms

Disputes over Nuclear Program Credit

Samar Mubarakmand has asserted that the (PAEC), under his leadership, developed the implosion-type nuclear device design independently of the uranium enrichment efforts led by at the (KRL). He supervised the complete assembly of the five devices detonated during Operation Chagai-I on May 28, 1998, at the Ras Koh Hills site in , emphasizing PAEC's role in weaponization beyond mere production. Mubarakmand further claimed that PAEC pursued a plutonium production pathway via reactors at , enabling diversified warhead options, while crediting his team for conducting cold tests and final preparations for the 1998 detonations. In contrast, A.Q. Khan positioned himself as the "father" of Pakistan's atomic bomb, highlighting KRL's centrifuge-based highly (HEU) production as the program's cornerstone, with claims that PAEC efforts were secondary or obstructive to KRL's progress. Tensions peaked during the tests, where Khan sought to personally trigger the —a role Mubarakmand reportedly opposed, leading to intervention by overseers to maintain operational control under PAEC. Khan disputed PAEC's post-test attributions, arguing that KRL's HEU fueled the devices and that enrichment breakthroughs enabled the program's viability, while downplaying PAEC's independent design capabilities. Empirical data from the tests underscores the interdependence of both tracks: seismic estimates placed Chagai-I's total yield at approximately 9-12 kilotons from five devices, consistent with low-efficiency fission implosions using HEU rather than advanced boosted designs, though Pakistani officials, including Mubarakmand, asserted higher yields up to 40 kilotons via sophisticated diagnostics. The subsequent test on May 30, 1998, involved a single device with an estimated 4-6 kiloton yield, attributed to PAEC's assembly under Mubarakmand's direction. Narratives minimizing PAEC's weaponization contributions overlook the causal necessity of implosion for compact, deliverable warheads, distinct from enrichment; state policy has enforced ambiguity to preserve institutional unity, avoiding explicit apportionment of credit amid rival claims. This duality reflects 's parallel pursuit of plutonium reprocessing and paths since the 1970s, with neither sufficient alone for a functional .

Allegations in Resource Projects

In the Thar Coal Underground Gasification (UCG) project, which Samar Mubarakmand chaired from its inception around , allegations of mismanagement and fund misuse surfaced due to significant delays and failure to achieve operational goals despite substantial expenditures. The project, intended to produce for power generation, consumed approximately Rs4.69 billion by 2018 without yielding viable output, prompting claims of wasteful spending on unproven technology and overstated feasibility. Critics, including observations, highlighted Mubarakmand's initial promises of generating "free " within years, which did not materialize amid technical challenges and bureaucratic hurdles, leading to accusations of incompetence or deliberate over-optimism favoring political interests over practical assessment. In October 2018, the , during hearings on the project's viability, ordered a forensic and directed the (NAB) to investigate potential corruption, including delays attributed to procurement irregularities and fund allocation under Mubarakmand's oversight. By 2018, the court explicitly instructed NAB to probe Mubarakmand and associated officials for causing financial losses through the unsuccessful initiative, emphasizing accountability for public funds in state-led resource ventures. No convictions have resulted from these probes, underscoring persistent risks of inefficiency and lack of oversight in 's resource extraction efforts, though defenders have attributed setbacks to external rather than inherent flaws. Regarding the copper-gold project, Mubarakmand provided expert testimony on resource estimates, but his statements faced scrutiny for alleged misrepresentations that exacerbated disputes leading to losses for . In 2020 proceedings, a senior official noted inaccuracies in Mubarakmand's input on valuations, potentially linked to broader claims of corrupt practices in deal negotiations and evaluations during the Musharraf . These elements contributed to NAB inquiries into and favoritism in the project, though direct charges against Mubarakmand remain unfiled, highlighting systemic vulnerabilities in high-stakes concessions prone to political interference.

Mubarakmand served as the founding Chairman of the National Engineering and Scientific Commission (NESCOM) from 2001 to 2007, directing efforts to integrate defense technologies such as development and production for Pakistan's strategic arsenal. Under his leadership, NESCOM coordinated multidisciplinary projects to enhance capabilities through scientific and engineering advancements. In a 2024 address, Mubarakmand highlighted the institutional role of the Pakistan Atomic Energy Commission (PAEC) in the nuclear program, stating that of the 140 personnel involved in the 1998 nuclear tests, 90 were technicians and engineers, thereby underscoring collective institutional contributions over individual prominence. Mubarakmand's 2025 public statements revealed Pakistan's progress in developing miniaturized tactical nuclear warheads, focusing on technologies that enable deployment on short-range systems for credible battlefield deterrence against superior conventional forces, particularly from India. These disclosures emphasized successful warhead miniaturization to fit missile constraints while maintaining yield efficacy for tactical scenarios.
