With several new delivery systems in development, four plutonium production reactors, and expanding uranium enrichment infrastructure, Pakistan’s stockpile has potential to increase further, the Nuclear Notebook said
A report has said that Pakistan has continued to "expand its nuclear arsenal with more warheads" even as its citizens suffer through a cash-strapped economy.
The US Defense Intelligence Agency projected in 1999 that Pakistan would have 60 to 80 warheads by 2020, but several new weapon systems have been fielded and developed since then, which leads us to a higher estimate," the Nuclear Notebook column published in the Bulletin of the Atomic Scientists on September 11 said.
