JF-17 vs J-10C: A Quick Comparison

To strengthen its combat prowess, Pakistan has stepped up its defense capabilities and has recently inducted Chinese acquired multi-purpose J-10C fighter jets into its Air Force. Though rumors about Pakistan buying the J-10 have been circulating for a long, its closest announcement was only made last December 29. However, finally, the induction of J-10C fighter jets happened on Friday, March 11, at Minhas Air Base.

In a simple ceremony attended by Prime Minister Imran Khan, the heads of the three services, the Chinese ambassador, and others, the Pakistan Air Force unveiled its latest addition – the next-generation Chinese fighter jet, the J-10C.

Although PAF is currently flying a fleet of jets, including JF-17, that has been effectively guarding the aerial boundaries of Pakistan since inducted by the PAF in February 2010. But after, the arrival of Chinese-made J-10C aircraft in the Pakistan Air Force – has sparked a debate in the region regarding how these aircraft differ from the previously owned JF-17.

Here is a brief comparison of the JF-17 vs J-10C.

JF-17 Fighter Overview

JF17 Thunder Aircraft

Joint Fighter-17 (JF-17) is an aircraft jointly developed by Pakistan’s Aeronautical Complex (PAC) and China’s Chengdu Aircraft Corporation (CAC)

The Pakistan Aeronautical Complex (PAC) possesses a 58% share in the co-production of the JF-17 airframe. In November 2009, PAC completed the final assembly and flight testing of PAC’s first production of the JF-17. 

Specifications and Features

This highly capable, air-to-air, and air-to-surface multi-role fighter is an advanced, lightweight, day/night, all-weather aircraft. JF-17’s advanced avionics, optimally integrated sub-systems, computerized flight controls, and ability to use the latest weapons give it a decisive edge over its counterparts. 

Aerodynamically, the JF-17 Thunder has a conventional layout. Its engine is a Klimov RD-93 turbofan with an afterburner, which is a derivative of the RD-33 found in the MiG-29.

With outstanding tactical manageability at low and medium altitudes, the aircraft has adequate firepower, agility, and combat survivability, making it a powerful platform for any air force.

Critical components of the JF-17

Among the critical components of the JF-17 avionics are the KLJ-7 Al radar and Weapon Mission Management Computer (WMMC), both of which have been problematic.

  • KLJ-7 radar displays degraded behavior, and its operation and maintenance are also problematic. Meanwhile, the WMMC has limited capacity, and several modules have shown high failure rates, including the Main Computer.
  • Due to WMMC malfunction, Launch Zones of air-to-air missiles beyond visual range have shrunk during combat exercises. And due to unreliability, PAC is now trying to manufacture WMMCs indigenously
  • The weapons load is not impressive also. The aircraft’s integral 23 mm gun has stopped firing in the air, and now, it has problems with 23 mm rounds bursting.

JF-17’s performance issues are attributed mainly to its single RD-93 engine, which is notoriously difficult to maintain. Besides, the JF-17 has other problems that include “Nose Landing Gear shimmies while taxing as well as nose wheel vibration”. Additionally, ventral trails have been found cracked, indicating poor metallurgy.

Variants of JF-17

  • JF-17A Block 1
  • JF-17A Block 2
  • JF-17B Block 2
  • JF-17 Block 3

Operators of JF-17

As of now, besides Pakistan and China, Myanmar and Nigeria are countries operating JF-17.

J-10C Overview

Jian 10 (J-10) is an indigenous Chinese multi-role fighter developed by Chengdu Aircraft Industry.

The aircraft carries the NATO designation ‘Firebird’ and is also called ‘Vigorous Dragon.’

Specifications and Features

The J-10 is a single-engine, multi-role fighter designed for air-to-air warfare and strike missions, and it is capable of operating in all weather conditions. Air-to-air and surface-to-surface missiles can be fired from the aircraft, which hit targets beyond the human eye’s reach with BVR (beyond the range of vision).

There is also a 23 mm machine gun on board, as well as L-15 missiles that can reach 200 km from the air, PL-8 missiles that reach close range, and J10C laser-guided bombs that can mass more than 500 kg to hit the ground in free fall.

J-10C, with its state-of-the-art radar, detects up to ten targets simultaneously and hits four at a time. A 4.5 generation jet fighter, the J10C comes with a Gold Quality Radar. It is capable of identifying the enemy in current war conditions and is able to withstand Jamir attacks. 

The J-10 has 11 external hardpoints that can carry a variety of weaponry. It is also capable of storing target acquisition systems, navigation pods, and supplementary fuel tanks. The aircraft can refuel while in flight.

The J-10C is said to be remarkably similar to the F-16s that form the backbone of Pakistan’s air force. Still, it is a more attractive alternative for Islamabad because the F-16 is tethered to several US requirements.

Variants of J-10C

  • J-10A
  • J-10AH
  • J-10S
  • J-10SH
  • J-10B
  • J-10B TVC Demonstrator
  • J-10C
  • J-10CE

Operators of J-10C

As of now, Pakistan is the other country besides China that will operate J-10C.

JF-17 vs J-10C: How do they differ?

Both the JF-17 and J-10 are lightweight fighter aircraft, but their weights differ considerably. The J-17s are considered “very light” fighters. Their engines are from mediumweight fighters instead of heavyweights, and they use a single configuration. In contrast, J-10 is also a lightweight jet. However, it borrows an engine from the heavyweight fighter class and instead uses a twin configuration. 

By being lighter and using a smaller engine, the JF-17 is not only significantly cheaper to manufacture but also easier and less expensive to operate than the J-10. A low maintenance requirement and high attack and availability rate make the JF-17 comparable to the Gripen. In comparison, the J-10 is significantly more expensive to operate and produce but is still quite affordable in comparison to jets of the same weight as the J-16 and has superior performance.

Though Pakistan has acquired a squadron of J-10C aircraft or may replace some of the older F-16 aircraft, the JF-17 Block 3 aircraft are expected to account for the vast majority of new acquisitions and may well be purchased in greater numbers than older JF-17 models.

Also, according to Shi Hong, chief executive editor of the Chinese magazine, J-10C will not replace the JF-17 in Pakistan but will form a combination with it, giving Pakistan enhanced combat capabilities.

Let’s look at the technical specification of JF-17 vs J-10C.
