Pakistan’s three F-16A/B Block-15 squadrons are scheduled to retire by 2040, with no service life extension left to keep them flying past that point.
The F-16 as the Pakistan Air Force’s workhorse
The F-16 is described in the source material as the Pakistan Air Force’s (PAF) mainstay multi-role fighter, prized less for a single standout capability than for “reliability and consistently high availability.” The jets are embedded in daily force structure: they fly alongside JF-17 Thunder and J-10C formations and perform the wide range of missions air headquarters expects of a workhorse platform. Replacing three squadrons — roughly 50 to 55 airframes — is therefore more than a swap of designs on paper; it is a question of preserving an operational role and tempo across the force.
$686 million support deal and the 2040 retirement timeline
The 2040 retirement date is effectively reinforced by a $686 million support and upgrade deal Pakistan signed with the United States in December 2025, a contract aimed largely at keeping the F-16 fleet viable through the 2030s. That timeline sets the parameters for the PAF’s next major fighter decision: the procurement cycle is set to open in the late 2020s and is expected to materialize through the 2030s, meaning any replacement will define force structure for decades.
The J-35AE offer and stealth trade-offs
The Shenyang J-35AE, offered through the Aviation Industry Corporation of China (AVIC), is presented as the leading candidate largely because it is the only fifth-generation aircraft currently on offer to the PAF. The hosts of the Defence Uncut podcast, Bilal Khan and Arslan Khan, caution that a stealth fighter does not automatically substitute for the F-16’s workhorse role. Low-observable designs tend to carry smaller payloads and require more maintenance between sorties — limits that complicate assigning J-35AE the same daily operational duties the F-16 performs.
Eurofighter Typhoon, F-16 Block 72, and Chinese heavyweights
The episode lays out several alternative paths. The Eurofighter Typhoon is argued to be worth reconsidering: cost-per-flight-hour comparisons, the hosts say, make it less prohibitively expensive than commonly assumed when one factors a Typhoon’s ability to carry heavy payloads over long ranges — potentially substituting one heavy aircraft for several lighter ones. Political constraints remain, however: Germany places restrictions on integrating Pakistani munitions, though the hosts note interface solutions and Türkiye’s own new-build Typhoon order could influence that calculation.
There is also a strong case made for new-build F-16 Block 72s. Because the PAF already operates the Block 52, inducting the closely related Block 72 would carry “little transition difficulty,” and the F-16 production line is expected to support airframes into the 2070s. The hosts add that, if available, the PAF might prefer a Chinese heavyweight such as the J-16 — given that aircraft’s role as the People’s Liberation Army Air Force’s mainstay — but the J-16 option is not currently on the table. Older strike platforms such as the JH-7B are treated in the discussion as dead ends.
Azerbaijan’s JF-17 Block III and Pakistan Aeronautical Complex (PAC)
The episode opens with a related development: Azerbaijan has shown a newly inducted JF-17 Block III fleet. Nine aircraft were produced in 2024 and wear the same livery as the PAF’s own jets, appearing externally identical in configuration. The hosts unpack technical and procurement details: the twin-seat JF-17B question (those airframes were delivered in a Block II configuration despite being designed for Block III compatibility) and the prospect of Turkish weapons integration carried out through Pakistan Aeronautical Complex (PAC). An Azerbaijani-funded customization path, the hosts suggest, could create new options for the PAF’s JF-17 fleet and potential export avenues as Block III matures in a second operator’s service.
What this means for the PAF, PAC, and regional partners
- For the PAF: The service must identify an aircraft able to do the F-16’s wide-ranging missions across three squadrons and 50–55 airframes while weighing interoperability with NATO and partners such as Saudi Arabia and Türkiye.
- For Pakistan Aeronautical Complex (PAC): PAC is positioned as a potential integrator for foreign weapons (notably Turkish systems) and as a node for any Azerbaijani-funded customizations that might inform Pakistan’s own JF-17 development.
- For regional partners and suppliers: Germany’s munitions-integration restrictions, Türkiye’s Typhoon order, and AVIC’s J-35AE offer create competing political and industrial vectors that will shape which platforms are feasible beyond technical performance.
The PAF’s choice will be technical and political in equal measure. The December 2025 support deal buys time through the 2030s, but the procurement cycle beginning in the late 2020s will force a decision that could define the service’s fighter composition into the 2070s. Whether that decision favors a stealth J-35AE, a Eurofighter solution navigated around political limits, new-build F-16 Block 72s, or some hybrid pathway tied to JF-17 evolutions and PAC-led integrations remains the central question raised by the podcast hosts.
