JF-17 Thunder

China and Pakistan's lightweight, low-cost multirole fighter — a 4/4.5-generation export workhorse with AESA in Block III, and the backbone of the Pakistan Air Force.

Overview

The JF-17 Thunder, designated FC-1 Xiaolong (“Fierce Dragon”) in China, is a single-engine lightweight multirole fighter co-developed by the Chengdu Aircraft Corporation (CAC) of China and the Pakistan Aeronautical Complex (PAC). Designed as an affordable, export-oriented platform, the JF-17 equips the Pakistan Air Force (PAF) as its most numerous combat type and has been sold to Myanmar, Nigeria, and Azerbaijan. Block III, entering service around 2023, elevates the type to a 4.5-generation capability through an air-cooled AESA radar and the long-range PL-15E beyond-visual-range missile.

Development

CAC and PAC began work on a low-cost fighter to replace Pakistan’s legacy Mirage and F-7 fleets in the late 1990s. The first prototype flew on 25 August 2003, and Pakistan formally inducted the initial Block I aircraft in 2007, according to Wikipedia. Block II followed with improved avionics and aerial-refuelling capability, while the two-seat JF-17B first flew in 2017. The definitive Block III, integrating a Chinese AESA radar and expanded weapons, was unveiled in 2019 and began PAF deliveries around 2023. Export interest remains high; in 2025 the type was touted as a candidate for Saudi Arabia’s fighter diversification, per The War Zone.
