ZBD-04A

China's primary modern tracked infantry fighting vehicle — a BMP-3-influenced design armed with a 100 mm gun-launcher and coaxial 30 mm autocannon, fielded by the PLA Army in its heavy and medium combined-arms brigades with no combat history to date.

Overview

The ZBD-04A, also designated Type 04A within the PLA and known industrially as part of the WZ-502 family, is the principal modern tracked infantry fighting vehicle of the People's Liberation Army Ground Force. Developed by NORINCO, it carries a crew of three and up to seven dismounted infantry, and mounts a distinctive dual-caliber armament package — a 100 mm rifled gun-launcher alongside a 30 mm coaxial autocannon — a philosophy inherited directly from the Russian BMP-3. The ZBD-04A is amphibious via rear water-jets, weighs approximately 24 tonnes, and has been produced in the low thousands across its family, though it has never been exported or tested in combat.

Development

The ZBD-04 lineage begins with the ZBD-97, which entered PLA service in 1999 as China's first modern tracked IFV. Building on that base, NORINCO developed the improved ZBD-04A variant — up-armored, heavier, and better protected — which was fielded through the 2010s and publicly showcased at the October 2019 National Day parade in Beijing. The design deliberately adopted the Soviet-Russian armament concept of pairing a 100 mm low-pressure gun capable of launching both high-explosive shells and tube-launched anti-tank guided missiles with a 30 mm autocannon, aiming to give a single vehicle robust direct-fire support and anti-armor capability without the need for a separate external ATGM mount. This choice reflects a broader PLA preference, visible across the Type 05 amphibious family and the airborne ZBD-03, for the BMP-3's integrated gun-launcher approach over the Western model of a dedicated autocannon plus a separate guided-missile pod.
