The HD-5 (Hongzha Dianzi-5, or HongDian-5) is the electronic warfare (EW) variant of the Harbin Hong-5 light jet bomber, a Chinese licensed copy of the Soviet IL-28 (NATo codename; Beagle). The PLA Air Force (PLAAF) converted a small number of its H-5 bombers in the 1980s for electronic warfare and countermeasures (EW/ECM) roles. The aircraft is similar to the US Navy EA-6B Prowler in its missions and operation profile, though its technology is likely to be generations behind the latter. The aircraft has its original twin-23mm tail cannon turret removed to make room for the EW/ECM suite. The three-man crew includes a pilot, a navigator and an electronic equipment operator.

HD-5（轰炸 电子-5，或轰电-5）是哈尔滨轰-5轻型喷气轰炸机的电子战（EW）改型，一种经许可苏联IL-28（北约代号：“猎兔犬”）的中国仿造型。PLAAF在1980年为电子战和对策（EW/ECM）任务改装了少量它的H-5轰炸机。飞机在它的任务和操作描述上与美国海军EA-6B“徘徊者”类似，虽然它技术上可能比后者落后一代。飞机上原来的双23毫米尾炮塔移除去腾出空间给EW/ECM组件。三名组员包括一名飞行员、一名导航员和一名电子设备操作员。

The EW/ECM suite onboard the HD-5, which is reportedly based purely on analogue technology, can intercept, identify and jam hostile land-based or shipborne radar emitters. The HD-5 usually operates in group of three to cover all spectrum of frequency. Despite its ageing technology, the powerful jammer onboard the aircraft is said to be very effective. One example was interfering of civilian frequencies far beyond the exercise zone during an exercise in 1997. The obsolete HD-5 is being replaced by the more capable EW/ELINT aircraft based on the Y-8 airframe.

HD-5机载EW/ECM组件，据传闻纯粹地建立在模拟技术上，能拦截、识别并干扰敌方陆基或舰载的雷达射极。HD-5通常在三组频谱中操作去覆盖所有频谱。尽管它技术老化，机载强大的干扰发射机据说非常有效。一个例子是在1997年的一次演习期间距离演习区域很远的民用频率受到妨碍。过时的HD-5被基于Y-8机身更有能力的EW/ELINT飞机代替。
