Three Muslim Nations Sign Mecca Joint Defense Pact: What Their Combined Military Power Looks Like

Leaders of Saudi Arabia, Turkey, and Pakistan signed the Joint Defense Agreement in Mecca last Friday (August 7, 2026), committing to enhanced collective deterrence against any act of aggression. Under the agreement, an armed attack on any one of the three nations will be considered an attack on all.

The deal was signed amid rising regional tensions, including concerns over Israel's expanding military capabilities and Iran's regional influence.

With Riyadh as a leading oil exporter, Ankara possessing NATO's second-largest military, and Islamabad being the only Muslim nation with nuclear weapons, the trio together forms a military bloc of considerable strength.

Combined Strength: Infantry, Air Force, and Navy

According to the 2026 Global Firepower Index (ranking the defense capabilities of 145 nations), the three countries collectively have nearly 1.4 million active-duty personnel, about 3,400 aircraft, over 6,000 tanks, and more than 340 naval vessels.

Personnel: Pakistan contributes the largest force with 660,000 troops, followed by Turkey with 481,000, and Saudi Arabia with 247,000. This is complemented by significant paramilitary and reserve forces.

Air Force: The three nations operate a combined total of 3,415 military aircraft, including fighters, helicopters, transports, and trainers. Pakistan has approximately 1,397 aircraft, followed by Turkey with 1,101 and Saudi Arabia with 917.

Army: The combined tank fleet numbers 6,046, supported by over 179,000 armored vehicles, thousands of artillery systems, and multiple launch rocket systems. Pakistan has the largest tank fleet with 2,677, Turkey has 2,284, and Saudi Arabia has 1,085.

Navy: The combined fleet includes 344 warships, including 33 frigates, 24 corvettes, and 22 submarines. Turkey leads with 192 vessels, followed by Pakistan (120) and Saudi Arabia (32).

Defense Spending: The combined annual defense budget of the three nations is approximately $124.4 billion. Saudi Arabia has the largest budget at $63.9 billion in 2026, while Turkey allocates $51.4 billion and Pakistan $9.1 billion.

Complementary Strengths

Analysts emphasize that the treaty's significance lies in the complementary strengths of the three nations. According to Andreas Krieg, a Middle East security analyst, Saudi Arabia contributes capital, geographic position, infrastructure, and political weight. Turkey brings its increasingly sophisticated defense industry, including drones, missiles, sensors, electronic warfare, naval systems, and NATO military experience. Pakistan offers manpower, a large professional military, combat experience, defense production capabilities, and its nuclear arsenal.

Implications for Each Nation

For Saudi Arabia, the pact diversifies its defense partnerships with the US, adding Turkey's advanced military capabilities and Pakistan's nuclear deterrence amid growing threats to vital sea lanes such as the Strait of Hormuz and Bab al-Mandeb.

Pakistan is one of nine nations possessing nuclear weapons, with its first test in 1998. It has a population of over 250 million and relies heavily on China for arms imports.

Turkey joined NATO in 1952, does not have its own nuclear weapons but hosts US nuclear warheads under NATO's nuclear sharing agreement.

David Des Roches, former director for Arabian Peninsula affairs at the US Department of Defense, suggests the agreement helps Saudi Arabia diversify its weapons suppliers. Turkey and Pakistan can provide items like 155mm artillery shells on a large scale, given the instability of Western exports. Conversely, the pact opens Saudi financial markets to the defense industries of Turkey and Pakistan, both of which have production capacity exceeding domestic needs.

The US role in this agreement is notable. According to Zaid M Belbagi, managing partner at Hardcastle Advisory, Pakistan is a US aid recipient, Saudi Arabia is the largest foreign military sales customer, and Turkey has NATO's second-largest military. However, Krieg argues that the old "hub-and-spoke" security model with the US at the center is shifting toward horizontal connections among regional powers.

Who Might Join Next?

Egypt is the only country publicly mentioned by a signatory as a potential addition. Turkish Foreign Minister Hakan Fidan called Egypt a "natural partner" and expressed hope that Cairo would join once technical issues are resolved.

Analysts say whether Egypt joins depends on whether the treaty's language protects its aid relationship with Washington, does not undermine existing peace agreements, and preserves its autonomy in military affairs.
