J-10A Initial Production Timeline
Spoiler
- Maiden Flight & Production Start:
The J-10 prototype (01st airframe) completed its maiden flight on March 23, 1998, but full-scale production of the early variant (J-10A) began in 2002.- Limited Batch Delivery: Approximately 10 pre-production units were delivered to the Chinese Air Force’s Test and Training Base (Cangzhou) in 2003 for tactical evaluation.
- Mass Production: Stable mass production by Chengdu Aircraft Industry Group (CAC) commenced in 2004, with the first operational J-10A units officially entering service in 2005 (e.g., PLAAF’s 44th Division).
J-10A Mid-Life Upgrade (MLU) Timeline
Spoiler
- Background:
To counter advancing fourth-generation+ threats (e.g., F-16V, Su-30MKI), the PLAAF initiated the J-10A modernization program (codenamed J-10A+ or J-10AH for naval variants) in 2015. - Upgrade Phases:
- Start: 2016 – First upgraded prototype completed modifications and test flights.
- Peak Activity: 2017–2020 – Roughly 200 J-10A units underwent upgrades.
- Completion: By 2022, most active J-10A fleets were upgraded, excluding early-production airframes with limited service life.
- Key Upgrades:
- Radar: Replaced with a domestic Passive Electronically Scanned Array (PESA) radar (KLJ-3V), boosting detection range by 30%.
- Data Link: Integrated with the Tri-Service Common Data Link, enabling seamless coordination with AWACS (e.g., KJ-500) and newer fighters like the J-10C.
- Electronic Warfare (EW): Enhanced Radar Warning Receiver (RWR) and KG600 ECM pods for improved survivability.
Production Line Transition & Shutdown
Spoiler
- J-10A Production Halt: CAC terminated J-10A production in 2014 to prioritize manufacturing of advanced variants (J-10B/C).
- Total Output: Approximately 260 units (including naval J-10AH).
- Production Line Adjustments:
- Internal Overhaul: Post-2015, J-10A assembly lines were repurposed for J-10C production.
- Subcontracting: Components (e.g., wings, tail sections) were outsourced to Guizhou Aircraft Industry Corporation (GAIC) to free CAC capacity for J-20 stealth fighter production.
J-10A Mid-Life Upgrade Developments
While most mid-life upgrades for the J-10A fighter were completed by 2022, official reports from the military, state media, and a documentary released by the 607 Institute of Radar Technology indicate that several remaining batches received further enhancements in 2023. These later upgrades included the installation of the WS-10B “Taihang” turbofan engine, which provides a maximum thrust of up to 14 tons, significantly improving performance.
In addition, these upgraded aircraft were fitted with and tested the JKL-24 Active Electronically Scanned Array (AESA) radar. Although specific details about this radar remain classified, its appearance and development timeline suggest it may be either a technology demonstrator or a cost-effective variant of the KLJ-7A AESA radar, which is used on the J-10C and JF-17 Block 3.

2005 (early variants)
Visual Differences
2016 (later variants).
As a mid-life upgraded variant, the aircraft did not undergo structural modifications aside from improvements in avionics and engine performance. Therefore, its airframe-related specifications remain consistent with those of the early J-10A model as represented in the game.
