After Pakistan’s J-10C fighters decisively outperformed Indian aircraft in May 2025, the jet became a symbol of China’s growing airpower dominance. Indonesia’s purchase of the older J-10B highlights a cost-effective move but underscores the technological gulf between the two variants. The J-10C’s superior radar, avionics, and weapon systems make it the most capable Chinese fighter to date a game-changer in Asia’s evolving airpower dynamics.
ISLAMABAD — When Indonesia confirmed the purchase of China’s J-10B fighter jets, analysts hailed it as a cost-effective move to modernize its air fleet. But the real story lies in what Indonesia is not getting the more advanced J-10C, a fighter that has already proven its mettle in modern combat under the Pakistan Air Force (PAF).
The Chengdu J-10 series, developed by China’s Chengdu Aircraft Corporation (CAC), represents the pinnacle of Beijing’s decades long effort to achieve self-sufficiency in military aviation. Nicknamed the “Vigorous Dragon,” the J-10 combines delta wings and canards for exceptional maneuverability, agility, and multirole capability. But after the events of May 9, 2025, the J-10C became more than just a fighter jet it became a symbol of China’s airpower transformation and combat credibility.
The Turning Point: May 9, 2025 Pakistan’s Combat Debut of the J-10C
In one of the most talked-about air engagements of the decade, Pakistan’s J-10C squadron reportedly shot down 5–7 Indian fighter aircraft during a night confrontation, while evading radar-guided counterattacks. The incident sent shockwaves across South Asia and reshaped regional defense calculations overnight.
The performance of the J-10C equipped with active electronically scanned array (AESA) radar, advanced data fusion, and beyond-visual-range (BVR) combat systems validated years of Chinese investment in indigenous avionics and sensors. Within hours of the engagement, CAC’s stock surged sharply on the Shanghai exchange, reflecting investor confidence in China’s growing dominance in the global fighter export market.
For Pakistan, the J-10C was more than a technological upgrade; it became an equalizer against India’s Rafales and Su-30MKIs. For China, it was the moment the Vigorous Dragon proved its bite.
Indonesia’s J-10B Purchase Strategic, but a Step Behind
Indonesia’s decision to purchase second-hand J-10B fighters from the People’s Liberation Army Air Force (PLAAF) signals Jakarta’s intent to strengthen its airpower on a limited budget. The move makes sense for a country seeking rapid modernization without the political complexities tied to U.S. or Russian platforms.
However, the J-10B while capable and combat ready lacks several key advancements that define the J-10C’s supremacy in 21st-century air warfare.
Radar & Avionics:
The J-10B is fitted with a passive electronically scanned array (PESA) radar, capable of tracking 10 targets and engaging four simultaneously. In contrast, the J-10C employs a cutting edge AESA radar that provides far superior detection range, tracking speed, and electronic warfare resistance. The C variant also integrates advanced data link systems for real-time coordination with AWACS and other fighters a decisive advantage in network centric warfare.
Propulsion:
While the J-10B typically uses the Russian AL-31FN M1 engine, the J-10C is powered by China’s indigenous WS-10B Taihang turbofan, offering higher thrust, improved reliability, and full compatibility with Chinese built avionics. This shift not only enhances performance but also underscores China’s technological independence from Russia.
Electronic Warfare & Stealth:
The J-10C introduces enhanced radar-absorbent coatings, internal ECM systems, and better radar cross-section (RCS) reduction giving it limited stealth capability. The J-10B’s diverterless supersonic inlet (DSI) was an important step forward, but the C variant’s integrated ECM pods and digital flight systems make it significantly harder to detect and jam.
Weapons & Combat Integration:
The J-10C supports PL-15 and PL-10E air-to-air missiles both featuring modern seekers and extended ranges that rival U.S. AMRAAMs and European Meteors. The J-10B, meanwhile, remains limited to the PL-8 and PL-12 missiles, giving the C variant a much broader and deadlier engagement envelope.
Why the Difference Matters
The J-10C is not merely an upgrade it represents China’s evolution from imitation to innovation. While Indonesia’s J-10Bs will boost its airpower, they will not offer the same strategic deterrence that Pakistan’s J-10Cs currently provide.
Pakistan’s successful combat deployment of the J-10C has validated China’s fighter export strategy and redefined perceptions of Chinese-built aircraft in real-world conflict scenarios. For countries like Indonesia, Malaysia, or Egypt considering future acquisitions, the J-10C now stands as a combat-proven 4.5-generation platform capable of rivaling Western fighters in both performance and price.
In a region where air superiority can dictate the outcome of conflicts, the J-10C’s combat record against India’s advanced fleet has shifted the regional balance of power not just militarily, but also psychologically.
Strategic Takeaway
The Indonesia – Pakistan contrast reveals more than two different aircraft; it highlights two different stages of China’s aerospace strategy. Indonesia’s acquisition of the J-10B reflects affordability and accessibility, while Pakistan’s frontline use of the J-10C showcases China’s technological confidence and export maturity.
As Asia’s skies grow more contested, the “Vigorous Dragon” has already proven it can breathe fire and for nations seeking to modernize their air forces, the J-10C has become a symbol of a new, multipolar age of air warfare, where Chinese engineering stands shoulder to shoulder with the West.
