In our latest FAS Nuclear Notebook we estimate that Pakistan now has 110-130 warheads in its nuclear arsenal. This is an increase of about 20 warheads from the 90-110-warhead level we estimated in our previous Pakistani Notebook in 2011.
The Notebook is published as Pakistan’s Prime Minister Nawaz Sharif is arriving in Washington D.C. for a state visit and foreign minister Aizaz Chaudhry acknowledged for the record what everybody already knew: that Pakistan has developed “low-yield, tactical” nuclear weapons.
The warhead increase is due to several developments in the past four years: Deployment (or near-deployment) of two new short-range ballistic missiles (including the one Chaudhry was probably thinking about: the NASR) and a new medium-range ballistic missile. Moreover, development is underway of two extended-range ballistic missiles and two cruise missiles that will require production of additional warheads.
If the current trend continues, we estimate that Pakistan a decade from now could potentially have a stockpile of 220-250 warheads, which would make Pakistan the world’s fifth largest nuclear power. We do not believe that Pakistan has the capacity to increase its stockpile to 350 warheads, as has been suggested by some.
Pakistan’s archenemy, India, is also modernizing and increasing its nuclear arsenal. For an overview of India’s nuclear arsenal, see here.
With both Pakistan and India engaged in rapid and broad buildup of their nuclear arsenals, it is essential that their governments, as well as other state leaders, increase efforts to limit the nuclear arms competition that is in full swing in South Asian.

The FAS Nuclear Notebook is one of the most widely sourced reference materials worldwide for reliable information about the status of nuclear weapons and has been published in the Bulletin of the Atomic Scientists since 1987. The Nuclear Notebook is researched and written by the staff of the Federation of American Scientists’ Nuclear Information Project: Director Hans […]
Charlotte Yeung’s latest work weaves Kurt Vonnegut’s stance on nuclear weapons with current issues we face today.
New U.S. Air Force budgetary documents strongly imply that the United States Air Force is in the process of re-establishing its nuclear weapons mission on UK soil.
Earlier this spring, the Department of Defense and Department of Energy twice rejected requests from the Federation of American Scientists to declassify the number of nuclear weapons in the US stockpile and the number of nuclear weapons awaiting dismantlement.
