🇵🇰 Nuclear Arsenal of Pakistan
Evolution of Pakistan Nuclear Arsenal
Overview in 2026
In 2026, Pakistan has a total of 170 nuclear warheads. They made 2 tests between 1998 and 1998.
Pakistan's nuclear weapons enterprise has matured into a diversified force geared to deter India at every rung of conflict through the doctrine of "Full Spectrum Deterrence" (FSD). Yet 2025 was a watershed year that shook the foundations of that strategy: India's Operation Sindoor (May 2025) demonstrated that Pakistan's nuclear threats could not prevent deep conventional strikes, while two high-profile missile test failures and US sanctions on Pakistan's long-range missile programme exposed critical vulnerabilities. India has also overtaken Pakistan in warhead count for the first time in over two decades (180 vs 170).
Pakistan is assessed to possess ~170 assembled warheads, unchanged since 2023. All warheads remain in central storage, not mated with delivery systems, though Strategic Plans Division exercises have shown missile units achieving launch readiness within hours. Fissile material production from four Khushab heavy-water reactors (~40–45 kg weapons-grade plutonium/year) could support 14–27 new warheads annually, but actual growth averages 5–10/year. The stockpile could reach ~200 by the late 2020s.
Operation Sindoor and the deterrence crisis
The April 2025 Pahalgam terror attack (26 killed) triggered India's Operation Sindoor (May 7–10, 2025) — precision strikes on 9+ targets inside Pakistan and Azad Kashmir, India's most extensive military action since 1971. Pakistan retaliated with Operation Bunyan-un-Marsoos, including mortar shelling on Jammu/Poonch and Fatah rockets at Indian military targets. On May 9, Pakistan fired a Fatah-II ballistic missile toward Delhi — intercepted over Sirsa, Haryana. PM Sharif convened the National Command Authority (NCA), but Pakistan rapidly backtracked under US diplomatic pressure, with the Defence Minister stating "the nuclear option is not on the table."
The conflict exposed structural weaknesses in Pakistan's deterrence posture. India "called Pakistan's nuclear bluff," operating decisively below the nuclear threshold. Post-crisis analysis concluded that FSD failed to prevent deep-penetration conventional strikes, and the burden for strategic stability has shifted toward Islamabad.
Force structure and major vectors
Land-based (Army Strategic Forces Command)
- Medium/intermediate-range: Shaheen-II (1,500–2,000 km), Shaheen-III (2,750 km, in final user trials), liquid-fuel Ghauri (1,250 km).
- Ababeel (~2,200 km, MIRV-capable): intended to be Pakistan's first MIRVed missile, but suffered a test failure in July 2025 — the second after October 2023. Technical challenges with post-boost vehicle stability have prompted a pivot toward a dedicated ICBM platform.
- Shaheen-III also suffered a test failure in July 2025, with the missile crashing near Dera Bugti, Balochistan, close to a nuclear facility — raising safety concerns.
- Short-range/tactical: Ghaznavi (300 km), Nasr/Hatf-IX (60–70 km, low-yield ~12 kt, deployed in regimental batteries against Indian armour).
- Ground-launched cruise missiles: Babur-1A/2 (350–700 km); new Fatah-IV (750 km subsonic GLCM, first tested September 2025).
Air-delivered (Air Force Strategic Command)
- Mirage III/V (~36 aircraft) remain the primary nuclear delivery platform, carrying Ra'ad-I/II ALCMs (350–600 km) and gravity bombs. At least 3 Mirage squadrons will retire by 2027, creating urgency for transition.
- JF-17 Block II/III: photographed carrying Ra'ad-I in 2023, but FAS assesses "too many uncertainties" for a confirmed nuclear role. Likely to assume the Mirage's nuclear mission as the fleet grows to 188+ aircraft.
- Taimoor ALCM: new 600 km low-observable air-launched cruise missile, first tested from a Mirage III on 3 January 2026 — terrain-hugging at 150m altitude.
Sea-based (Naval Strategic Forces Command)
- Babur-3 SLCM (450 km): tested twice from "underwater mobile platform" (2017, 2018); intended for nuclear second-strike capability but not yet operational.
- 3 Agosta-90B submarines: retrofitted for Babur-3 integration.
- Hangor-class (Type 039B): 8 AIP submarines under Sino-Pakistani co-production. Four launched in China — PNS Hangor (April 2024), PNS Shushuk (early 2025), PNS Mangro (August 2025), PNS Ghazi (December 2025). First induction expected mid-2026; all eight by 2028. Four more being built at Karachi Shipyard under technology transfer. Will provide a quiet, dispersed nuclear patrol capability once Babur-3 is integrated.
Long-range missile programme and US sanctions
In December 2024, the US imposed first-ever sanctions on a Pakistani state-owned entity — the National Development Complex (NDC) — for pursuing "increasingly sophisticated missile technology" including missiles that could "strike targets well beyond South Asia, including the United States." US intelligence assesses Pakistan is several years to a decade from an operational ICBM capability, with suspected technical assistance from Belarus and China.
Post-Sindoor restructuring
In August 2025, Pakistan established the Army Rocket Force Command (ARFC) — a new three-star-led organisation modelled on China's PLARF, controlling all conventional rockets and missiles (Fatah series, future hypersonic systems), separate from SPD's nuclear forces. This was a direct organisational response to the conventional missile capability gaps exposed during Operation Sindoor.
Outlook
Pakistan faces a widening strategic gap with India: India's MIRVed Agni-V, expanding submarine fleet (6 boats by 2027), and growing warhead count all outpace Pakistan's capabilities. The Ababeel MIRV and Shaheen-III failures undermine confidence in Pakistan's qualitative modernisation, while US sanctions constrain the long-range programme. The Hangor-class submarine programme remains the most promising near-term development, but integrating a reliable sea-based nuclear capability will take years. Rapid arsenal growth amid economic stress and internal militancy increases security burdens — the proximity of nuclear sites to militant-affected areas remains a persistent concern. The fundamental challenge is that Operation Sindoor demonstrated the limits of nuclear deterrence against a risk-tolerant adversary, forcing Pakistan to rebuild conventional credibility while sustaining its nuclear posture.
