When people talk about air power in South Asia, they usually get obsessed with raw numbers. It's a common trap. You look at a spreadsheet, see how many jets one side has versus the other, and think you've solved the puzzle. But the fighter aircraft of Pakistan Air Force (PAF) story isn't about having the biggest fleet. It’s about "swing-role" capability and some really aggressive indigenization that caught a lot of Western analysts off guard.
Basically, the PAF operates on a "high-low" mix, but with a twist. They aren't just buying off-the-shelf; they are building, tweaking, and sometimes completely overhauling the electronics inside these birds to make them talk to each other. If you’ve ever wondered why a relatively small air force stays so competitive, it’s not just the pilots. It’s the data links.
The JF-17 Thunder: More Than a Budget Jet
Let's talk about the backbone. If you look at the JF-17 Thunder, you’re looking at the most misunderstood plane in the region. Critics used to call it a "cheap Chinese copy," but that's honestly a lazy take. The JF-17 is a joint venture between Pakistan Aeronautical Complex (PAC) and Chengdu Aircraft Industry Group (CAIG).
It was born out of necessity.
Back in the 90s, sanctions hit hard. Pakistan couldn't get spare parts for its aging F-16s, and the Mirage III/V fleet was—let’s be real—getting ancient. They needed something they could build themselves. The JF-17 Block 1 was basic. The Block 2 added air-to-air refueling. But the Block 3? That’s where things get interesting. We’re talking about an Active Electronically Scanned Array (AESA) radar (the KLJ-7A), a sophisticated helmet-mounted display, and the ability to carry the PL-15—a long-range air-to-air missile that makes even top-tier fourth-gen pilots a bit nervous.
The beauty of the Thunder is its cost-to-kill ratio. You can fly three of these for the price of maintaining one heavy Western twin-engine jet. It’s the ultimate "workhorse" that actually has teeth.

The F-16 Fighting Falcon: The Elite Veteran
You can't discuss fighter aircraft of Pakistan Air Force without mentioning the Viper. The F-16 is the "gold standard" in the PAF, and for good reason. They’ve been flying them since the 1980s, and honestly, the PAF pilots might know the airframe better than almost anyone else in the world.
They have the Block 15s, which were upgraded under the Mid-Life Update (MLU) program, and the newer Block 52+ models. The Block 52s are the heavy hitters—equipped with conformal fuel tanks and the APG-68(V)9 radar. They provide the precision strike capability that the PAF relies on for high-value missions.
There’s a lot of political drama surrounding these jets, though. End-use monitoring and spare parts issues have made the F-16 a complicated asset. But in a dogfight? The PAF’s "No. 9 Griffins" or "No. 11 Arrows" squadrons are legendary for what they can do with this airframe. It’s the high-end part of the mix that keeps the neighbors looking over their shoulder.
The J-10C "Vigorous Dragon": Changing the Balance
In early 2022, something big happened. Pakistan inducted the Chengdu J-10C. This wasn't just another purchase; it was a strategic shift. For a long time, the PAF didn't have a direct counter to the Rafale.
The J-10C changed that.

It’s a 4.5-generation medium-weight fighter. It’s fast, incredibly agile with its delta-wing and canard configuration, and it’s packed with Chinese sensors that are, frankly, getting very close to Western standards. It uses the WS-10B engine, which means Pakistan is moving away from Russian engine dependencies. This jet represents the "High" in the high-low mix now, complementing the F-16 but without the political strings attached by Washington.
What about the old stuff?
It's kinda wild that the Mirage III and Mirage V are still flying. Most air forces retired these decades ago. But the PAF’s Project ROSE (Retrofit of Strike Element) breathed new life into them. They added Italian radars, new cockpits, and the ability to fire stand-off weapons. While they are being phased out by the JF-17, they still serve a purpose as dedicated strike platforms. They are old, sure, but in the hands of a pilot who knows the terrain, they are still dangerous.
Then there’s the F-7PG. It’s a specialized version of the Chinese MiG-21 clone. It’s basically a "point defense" interceptor. It doesn't have the range or the radar of a modern jet, but it's small, fast, and very hard to see in a visual range scrap. Think of it as the last line of defense.
The Stealth Future: Project Azm and the J-31
Nobody wants to fly a 4th-gen jet in a 5th-gen world forever. Pakistan knows this. For a while, everyone was talking about "Project Azm," the PAF’s ambitious plan to develop its own stealth fighter. Developing a Fifth-Generation Fighter Aircraft (FGFA) from scratch is incredibly expensive and technically exhausting.
So, they’ve pivoted.

Recent reports and official statements from PAF leadership suggest a move toward the Chinese Shenyang J-31 (also known as the FC-31 or Gyrfalcon). This is a twin-engine stealth fighter. If this deal goes through fully—and it looks like it is—it will make the fighter aircraft of Pakistan Air Force the first in the region to operate a dedicated stealth platform. That’s a massive leap. It changes the entry cost of any potential conflict.
How They All Work Together
This is the "secret sauce" people miss. The PAF uses something called the Link-17. It’s a domestic data link. It allows the JF-17 to talk to the F-16, which talks to the J-10C, which talks to the Saab 2000 Erieye (the AWACS or "eyes in the sky").
Imagine a JF-17 flying with its radar turned off so it doesn't give away its position. An Erieye AWACS, flying miles behind, sees an enemy target and "sends" that data to the JF-17. The JF-17 pilot sees the target on his screen as if his own radar found it, fires a missile, and turns away. The enemy never even saw the JF-17 on their radar. This is "network-centric warfare," and the PAF is surprisingly good at it.
Current Fleet Composition (Rough Estimates)
- JF-17 (Block 1, 2, 3): 150+ units (Growing)
- F-16 (A/B, C/D): 75-85 units
- J-10C: 25+ units (Growing toward 60+)
- Mirage III/V: ~80 units (Being retired)
- F-7PG: ~50 units (Being retired)
Actionable Insights for Aviation Enthusiasts
If you're tracking the development of the PAF, don't just look for new airframes. Look for the "force multipliers."
- Watch the AWACS: The number of Saab 2000 and ZDK-03 aircraft Pakistan operates is the real indicator of their combat effectiveness.
- Monitor the PL-15 Missile: The integration of this long-range missile onto the JF-17 Block 3 and J-10C is what actually shifts the tactical balance.
- Check for Engine Tech: Watch if Pakistan begins domestic overhauls of the WS-10B engines. It tells you how independent their supply chain is becoming.
- Follow PAC Kamra: This is where the JF-17s are built. Any news coming out of this facility usually signals the next "Block" or upgrade cycle.
The fighter aircraft of Pakistan Air Force are in a state of rapid transition. The era of Western dominance in their hangars is fading, replaced by a sophisticated blend of Chinese hardware and Pakistani systems integration. It’s a pragmatic, high-tech approach to a very old rivalry.
