The Harbin H-5 is a Chinese-built derivative of the Soviet Ilyushin Il-28, produced by Harbin Aircraft Factory as a twin-jet tactical light bomber with a three-person crew and a 3,000 kg maximum bomb load. Chinese state-industry history describes the H-5 as heavily reworked for local production, with a redesigned wing, shared H-6 equipment, bomber-trainer, reconnaissance, electronic-warfare, torpedo, and nuclear-test variants, and Chinese service lasting until the early 2010s.
Khmer Rouge air forces received at least two and possibly three Chinese Harbin H-5 bombers in 1977; Aeroflight reports that an H-5 was claimed shot down during the Vietnamese invasion and that Vietnamese forces captured additional AFKLA aircraft as Phnom Penh fell.
The H-5 program began from Soviet Il-28 repair and manufacturing experience, but Chinese sources describe substantial adaptation rather than simple assembly. SASTIND says Chinese drawings accounted for about 40 percent of the aircraft, including a redesigned wing and domestic components; GlobalSecurity adds that the H-5 adopted H-6-related equipment, a different tail turret, improved radar and sighting equipment, and larger ammunition capacity.
Harbin Aircraft Factory moved from Il-28 repair and parts manufacture into H-5 prototype production after Soviet support ended.
The family included bomber, nuclear-carrier, torpedo, reconnaissance, trainer, electronic-warfare, and ejection-test adaptations.
The Cambodia row is supported as Khmer Rouge fielding, reported loss, and captured-equipment context; the cited sources do not confirm H-5 bombing sorties or target sets.
Chinese references treat the H-5 as more than a straight Il-28 copy: the baseline bomber led to nuclear-carrier, torpedo, reconnaissance, trainer, electronic-warfare, and test-aircraft adaptations.

China's Third Ministry of Machine Building approved the H-5 trial-production plan after Harbin's Il-28 repair experience and Soviet contract rupture pushed the program toward local redesign.
