You’ve probably seen the footage of the J-15 "Flying Shark" screaming off the deck of the Liaoning. It looks impressive. It’s big, it’s loud, and it represents a massive leap for the People’s Liberation Army Navy (PLAN). But if you dig into the actual engineering, the J-15 fighter jet is a fascinating study in "making it work" under pressure. It’s a plane born from a bit of a geopolitical drama involving a prototype from Ukraine, a lot of reverse-engineering, and the harsh reality that landing a massive jet on a moving ship is incredibly hard.
Most people call it a Russian copy. That’s partly true. In the early 2000s, China wanted the Su-33 from Russia, but the deal fell through because Russia (rightly) suspected China just wanted a few to take apart and copy. So, China went to Ukraine and bought the T-10K-3, an unfinished Su-33 prototype. They spent years figuring out how it worked. The result is a heavy, twin-engine beast that is both China's pride and its biggest headache.
What the J-15 fighter jet actually does well
It’s huge. Honestly, the scale of the J-15 fighter jet is the first thing that hits you. Because it's based on the Flanker airframe, it has a massive internal fuel capacity. We’re talking about a jet that can stay in the air for a long time without needing a tanker. That’s a luxury most carrier pilots would kill for.
The cockpit is actually quite modern. While the Russian Su-33 was stuck with old-school "steam gauges" and analog dials for way too long, the Chinese variant jumped straight into glass cockpits. You have multi-function displays (MFDs) and a wide-angle Head-Up Display (HUD). This isn't just for show; it’s about reducing the pilot's workload. If you’re trying to land on a pitching deck in the South China Sea at night, you don't want to be squinting at a tiny dial from the 1980s.
Range matters. In a conflict, the ability to loiter or strike from a distance is everything. The J-15's size allows it to carry a significant variety of weaponry. We’re talking about the PL-12 and PL-15 for air-to-air combat, and the YJ-83K for anti-ship missions. If it can get off the deck with a full load—and that’s a big if—it’s a formidable opponent.
The Ski-Jump Problem
Here is the thing about the J-15 that most "fanboy" blogs ignore: the Liaoning and the Shandong don’t have catapults. They use a "ski-jump" (STOBAR) system.

Physics is a jerk.
Because the plane has to launch under its own power up a ramp, it can’t take off at its maximum weight. This is the J-15 fighter jet’s Achilles' heel. If you load it up with heavy anti-ship missiles and a full tank of gas, it’s going to end up in the water, not the air. This forces pilots to make a choice. Do you carry lots of fuel but no weapons? Or do you carry a lethal payload but have to return to the ship in 45 minutes because you’re running on fumes?
Engineers at the Shenyang Aircraft Corporation have been sweating over this for years. They've tried to lighten the airframe using composites. It helped, but you can’t outrun the laws of aerodynamics. This is why the newer J-15B is such a big deal. It’s designed for the new Fujian carrier, which actually has electromagnetic catapults (EMALS). Once you can sling-shot the Shark into the air, the "weight penalty" basically disappears.
Reliability and the "Widowmaker" Rep
For a while, the J-15 had a scary reputation. Between 2012 and 2017, there were several high-profile crashes. Cao Xianjian and Zhang Chao are two names often cited; Zhang tragically lost his life trying to save his aircraft during a flight control system failure.
The issue was largely the flight control system (FCS).

The J-15 uses a fly-by-wire system, which basically means a computer interprets the pilot's stick movements and moves the flaps and rudders. If that software glitches while you're at low altitude, you're in trouble. China's state media was surprisingly open about these struggles, which is rare. They eventually had to ground the fleet for a period to fix the "instability" in the flight controls.
Today, those kinks seem mostly worked out. You don't see the same frequency of catastrophic failures. But the J-15 remains a handful to fly. It’s heavy. It’s powerful. It’s got a high landing speed. It’s a "pilot’s plane," which is a polite way of saying it will kill you if you stop paying attention for even a second.
Comparison with the F/A-18 Super Hornet
People love to compare the J-15 fighter jet to the US Navy’s Super Hornet. It’s not a great comparison, honestly.
- The Super Hornet is smaller and slower.
- The J-15 has a much higher top speed (around Mach 2.4).
- The Hornet has much more advanced sensor fusion and electronic warfare suites.
- The J-15 has better raw "kinematics" (it turns and climbs better in some envelopes).
Basically, the Hornet is a sniper with a great radio, while the J-15 is a heavy-weight boxer. In a long-range fight, the US jet likely sees the J-15 first. But if it gets into a visual range dogfight? The Flying Shark's thrust-to-weight ratio and those big wings make it a terrifying prospect.
The Future: J-15B and the Stealth Question
Is the J-15 obsolete? Not even close.

Even as China tests the J-35 (their stealth carrier jet), the J-15 fighter jet is going to remain the workhorse. Think of it like the US Navy’s mix of the F-35 and the F-18. You use the stealthy J-35 to kick down the door and take out radar, then you send in the heavy-hauling J-15s to do the actual dirty work.
The newest variant, the J-15B, is a total overhaul. It has:
- AESA radar (Active Electronically Scanned Array).
- New pylons for the latest PL-15 missiles.
- Reinforced landing gear for catapult launches.
- Improved stealth coatings (though it'll never be "invisible").
It’s basically a 4.5 generation fighter now. It’s roughly equivalent to the latest Block III Super Hornets.
Actionable Insights for Military Tech Enthusiasts
If you're tracking the development of naval aviation, keep your eyes on the deck of the Fujian. The moment we see a J-15 fighter jet launch via a catapult, the strategic math in the Pacific changes.
- Watch for the "B" variant: Look at the nose gear. If it has a "launch bar" (a thick metal arm on the front wheel), that’s the catapult-ready version.
- Engine Upgrades: Pay attention to the nozzles. China is moving away from Russian AL-31F engines to their own WS-10 engines. The WS-10 is a sign of true domestic independence in jet production.
- The "Buddy Tanker" Role: One of the most common uses for the J-15 right now is actually refueling other J-15s. Because the ship lacks dedicated tanker planes, the "Shark" has to do it itself.
The J-15 isn't a "failed" jet. It’s a bridge. It’s the plane that taught China how to operate at sea, and it’s likely to be around for another two decades. It might have started as a "borrowed" Ukrainian design, but it has evolved into something uniquely Chinese, flaws and all. The "Flying Shark" is still very much hunting.
