As of 2024-2025, Pakistan is estimated to possess approximately 170 nuclear warheads. This estimate comes from multiple recent analyses, including the Bulletin of the Atomic Scientists and other defense intelligence sources. Pakistan's nuclear arsenal has been gradually expanding and modernizing, with projections suggesting it could grow to around 200 warheads by the late 2020s

. Pakistan began its nuclear weapons program in 1972 and conducted its first nuclear tests in 1998. The country does not adhere to a "no first use" policy and maintains a range of delivery systems including land-based missiles, aircraft, and potentially sea-based platforms

. In comparison to its neighbor India, Pakistan had maintained a slight numerical advantage in nuclear warheads for many years, but recent reports indicate that India has now slightly surpassed Pakistan's stockpile, with India estimated to have around 180 warheads as of early 2025

. Summary:

• Estimated current nuclear warheads: ~170 (2024-2025)
• Potential growth: Up to ~200 warheads by late 2020s
• First nuclear test: 1998
• Delivery systems: Land missiles, aircraft, and possibly sea-based
• No declared "no first use" policy

This information reflects the best available public estimates given Pakistan's high level of secrecy regarding its nuclear arsenal
