Pakistan’s Nuclear Program
Historical Development
- 1955: Pakistan’s nuclear program began with research cooperation with the US (Atoms for Peace program)
- 1958: PAEC (Pakistan Atomic Energy Commission) established under Dr. I.H. Usmani
- 1970s: Zulfikar Ali Bhutto launched uranium enrichment program after India’s nuclear test (1974)
- 1998: Chagai-I (28 May 1998) — Pakistan conducted 5 underground nuclear tests in Balochistan; became a nuclear state
Nuclear Tests (1998)
Chagai-I (Balochistan, 28 May 1998):
- 5 device tests including one with a boosted fission device
- Mountains of the Chagai district served as test sites
- Tests were underground (deep shafts) — consistent with CTBT (Comprehensive Test Ban Treaty)
Chagai-II (same day, 28 May 1998):
- 1 additional test confirming multiple device types
| Test Site | Location | Devices Tested |
|---|---|---|
| Chagai-I | Chagai Hills, Balochistan | 5 devices (including boosted) |
| Chagai-II | Chagai Hills, Balochistan | 1 additional device |
Key scientists: Dr. Abdul Qadeer Khan ( uranium enrichment), Dr. Samar Mubarik Mand (weapons design), Dr. Zia-ul-Haq (test coordination)
Nuclear Doctrine
- Full-scope nuclear deterrence against India
- Second-strike capability acknowledged
- No-first-use policy stated
- Strategic Command: Strategic Plans Division (SPD) under the Army
Peaceful Nuclear Applications
PAEC operates nuclear power plants:
- KANUPP (Karachi Nuclear Power Plant) — first nuclear power plant, commissioned 1972
- CHASNUPP-1 and 2 (Chashma Nuclear Power Plant, Punjab) — Chinese technology
- PAEC has 6 operational nuclear power plants contributing ~5% of Pakistan’s electricity
SUPARCO — Pakistan’s Space Program
History
- 1961: Pakistan Space and Upper Atmosphere Research Commission (SUPARCO) established — one of the earliest space agencies in Asia
- 1963: Rehbar-1 (first Pakistani rocket) launched with US cooperation
- 1989: Badr-1 (first Pakistani satellite) launched aboard a Chinese rocket
Recent Satellite Program
- Paksat-1R (2011): communication satellite; geostationary
- PRSS-1 (Pakistan Remote Sensing Satellite) (2018): Earth observation
- PakSat-MM1 (2022): multibeam communication satellite for broadband
- ICUBE-Qamar (2024): launched aboard China’s Long March 2C — Pakistan’s first CubeSat mission
SUPARCO’s Role
- Satellite communications and Earth observation
- Disaster management: satellite-based monitoring of floods, earthquakes
- Agricultural monitoring: crop estimation, land use mapping
