WarBrief Live | November 5, 2026 | Country Profile
Pakistan fields South Asia’s second-largest armed force and the Muslim world’s only nuclear arsenal, estimated at about 170 warheads, and in 2026 it sits at the center of a new Gulf security architecture built on two defense pacts with Saudi Arabia and Türkiye. The question now is whether those pacts make Pakistan a regional security guarantor, or overextend a military still defined by its rivalry with India.
Key Takeaways
- About 660,000 active personnel and an estimated 170 nuclear warheads, per IISS and SIPRI 2026 figures.
- Military spending rose 11 percent to $11.9 billion in 2025, driven by new Chinese aircraft and missile orders after the May 2025 conflict with India.
- The September 2025 Saudi-Pakistan defense pact and the August 2026 Makkah Pact with Türkiye commit the three states to treat an attack on one as an attack on all.
- Mediating between Iran and the United States while its airspace stays closed to Indian aircraft until November 24, 2026.
Overview
Pakistan is a nuclear-armed state of roughly 250 million people, bordered by India, Afghanistan, Iran and China, with an Arabian Sea coastline. Its military is built first for the eastern border: the rivalry with India has produced four wars and, in May 2025, the first missile and air exchange ever fought between two nuclear-armed states. That four-day conflict, triggered by the April 22, 2025 Pahalgam attack that killed 26 people, ended in a ceasefire within days. India attributes the attack to Pakistan-backed militants; Pakistan denies involvement, and the attribution remains contested. Two defense pacts signed in thirteen months have since tied Pakistan’s forces to Saudi Arabia’s security, and Islamabad now mediates between Iran and the United States. This profile examines Pakistan military capabilities in 2026, when the Makkah Pact made Islamabad a Gulf security guarantor as well as a South Asian nuclear power.
Military capabilities
About 660,000 active personnel, per International Institute for Strategic Studies (IISS) data cited by Reuters in July 2026: 560,000 in the army, 70,000 in the air force and 30,000 in the navy, including 3,200 marines, with roughly 550,000 more in reserve. The army fields more than 2,500 main battle tanks and over 4,600 artillery pieces.
The nuclear deterrent is the center of gravity. SIPRI Yearbook 2026 estimates about 170 warheads as of January 2026, a figure the Federation of American Scientists reached independently in September 2025; neither claims precision, since Islamabad has never published a count. The stockpile could reach about 200 by the late 2020s. Pakistan first tested in May 1998, describes its doctrine as full-spectrum deterrence, and rejects a no-first-use pledge. India holds an estimated 190 warheads on the same SIPRI count.
The air force flies more than 420 combat-capable aircraft, per IISS: American F-16s, Chinese J-10Cs and the JF-17 Thunder co-produced with China. The navy is the smallest service, its largest procurement an eight-boat Hangor-class submarine program with China. China supplied 81 percent of Pakistan’s arms imports in 2020-24, per SIPRI, and Pakistan was the world’s fifth-largest arms importer in 2021-25.

Alliances & posture
On September 17, 2025, Saudi Arabia and Pakistan signed a Strategic Mutual Defence Agreement in Riyadh whose published summary states that any aggression against either country shall be considered an aggression against both. Pakistan’s Foreign Office called it defensive and not directed against any third country. The public text contains no nuclear commitment, and Harvard’s Belfer Center notes nothing in it converts Pakistan’s India-focused doctrine into a Saudi umbrella — although Pakistan’s defense minister said in September 2025 that the country’s capabilities “will be made available” to the Kingdom, while also telling Reuters nuclear weapons were “not on the radar.”
The Makkah Joint Defence Agreement, signed by Saudi Arabia, Türkiye and Pakistan on August 7, 2026, goes further: its Article 2 treats an externally originating armed attack on any party as an attack on all. Türkiye’s parliament was scheduled to ratify it on November 5, 2026, according to Reuters, but ratification alone does not deploy Turkish forces — that needs a separate mandate. After Houthi strikes on the Kingdom, the three partners agreed on October 5 to activate collective deterrence measures, and regional reporting describes Pakistani troops, aircraft, drones and an air-defense system now deployed in Saudi Arabia. For readers of our country profiles, the pattern is clear: China remains Pakistan’s anchor arms supplier, while its alliance commitments now run through Riyadh and Ankara as well as Beijing.
Current developments
The airspace standoff with India continues: on October 17, 2026, the Pakistan Airports Authority extended its ban on Indian aircraft until 04:59 Pakistan time on November 24, 2026. The ban, first imposed on April 23, 2025, covers Indian-registered aircraft and aircraft owned, operated or leased by Indian airlines, including military flights. India maintains a reciprocal ban.
Pakistan is also mediating between Iran and the United States. Field Marshal Asim Munir visited Tehran twice in October, most recently on October 26 alongside the Saudi defense minister and the Turkish intelligence chief, in talks our Iran mediation report covers in detail. Pakistan’s military spokesman told Reuters on October 30 that Islamabad is “cautiously optimistic,” while warning of “powerful spoilers and detractors.” The October 26 visit — described in our report on the Mecca Pact’s Tehran talks — showed the pact’s three members acting as mediators toward Iran even as they confront Houthi attacks on Saudi Arabia. Whether the pact works as a shield for the Kingdom, a channel to Tehran, or both will determine how much of Pakistan’s military weight is now committed outside South Asia.
Frequently asked questions
How many nuclear weapons does Pakistan have?
About 170, according to independent estimates published by SIPRI Yearbook 2026 and the Federation of American Scientists in 2025. Pakistan has never published an official count, so the figure is an estimate based on fissile-material production and delivery systems.
What is the Makkah Pact?
A trilateral defense agreement signed by Saudi Arabia, Türkiye and Pakistan on August 7, 2026. Its Article 2 treats an externally originating armed attack on any member as an attack on all. Türkiye’s parliament was scheduled to ratify it on November 5, 2026; ratification alone does not authorize deploying Turkish forces.
Does the Saudi-Pakistan defense pact extend Pakistan’s nuclear deterrent to Riyadh?
No public clause does. The September 2025 agreement commits each side to treat an attack on the other as an attack on itself, but it mentions no nuclear sharing, and Pakistani officials have given conflicting signals. Analysts at Harvard’s Belfer Center conclude the pact does not create a Saudi nuclear umbrella.
