The Pakistani Nuclear Story

Pakistan set out, in the space of twenty six years, to build a nuclear weapon. This is the record of how that work was done.

The story is drawn from declassified material, official statements, biographical sources and the standard scholarship. It gives weight to the Pakistan Atomic Energy Commission line of work alongside the more publicly visible Khan Research Laboratories, because the bomb was not the work of a single man. It was the work of a small community trained inside particular European and American schools of physics.

If India builds the bomb, we will eat grass or leaves, even go hungry, but we will get one of our own. We have no other choice.
Zulfikar Ali Bhutto to the Manchester Guardian, September 1965.

Story.

The entries below sit in seven eras. Choose one to read. The dates run continuously from the founding of PAEC in 1956 to American sanctions on the National Development Complex in December 2024.

Scientists.

Twenty two working biographies, placed in the order in which they joined the programme. Each entry identifies the specific university, supervisor and year. The names at the end of each entry point to the teachers in whose tradition they trained.

Mentors.

Twenty two teachers and the schools they came from. The line runs through the Cavendish under Rutherford, Imperial College under Thomson and Salam, Cambridge under Kemmer, Birmingham under Peierls and Moon, Oxford under Wilkinson, Copenhagen under Bohr, Princeton under Oppenheimer, Argonne under Zinn, and Oak Ridge under Weinberg. The names at the end of each entry point to the Pakistani scientists who studied in their tradition.

A single photograph captures the teaching lineage that runs through almost every Pakistani name in this record.

Sites.

Twelve facilities carry most of the operational weight. Some sit in public view, like the power reactors at Karachi and Chashma. Others are remote and closed, like the test tunnels in the Ras Koh range and the centrifuge cascades at Kahuta.

Operations.

The programme was watched, photographed, infiltrated, baited, sabotaged and surveilled. Pakistani intelligence in turn defended it with methods no less elaborate. The entries below are documented operations drawn from declassified materials and the standard scholarship.

Doctrine.

Pakistani nuclear doctrine has changed three times since 1998. The structure of command has been formalised, the inventory has grown, and the four red lines articulated by Lieutenant General Khalid Kidwai in January 2002 remain the most explicit statement of intent.
