China Aerospace Science and Technology Corporation (CASC) has developed improved versions of its CH-3, CH-4, and CH-5 Cai Hong (CH) or Rainbow series of medium-altitude long-endurance (MALE) unmanned aerial vehicles (UAVs), adding to the country's line-up of unmanned platforms that can be employed domestically and sold to foreign operators.

中国航天科技集团公司（CASC）已研发出改进版的CH-3、CH-4和CH-5彩虹（Cai Hong，CH）或彩虹（Rainbow）系列中空长航时（MALE）无人机，增加了该国可在国内使用并出售给外国运营商的无人驾驶平台阵容。

 

The Rainbow series of UAVs is expansive, spanning at least 10 primary fixed-wing models (those with a maximum take-off weight [MTOW] of at least 120 kg). The largest is the eight-tonne stealth CH-7, which is in development for the Chinese People's Liberation Army (PLA). However, CASC's decision to improve the CH-3/4/5 series is based on the type's operational versatility and its export credentials, having been collectively sold to at least eight countries.

彩虹系列无人机拥有庞大的机型阵容，至少包含10款主要固定翼型号（最大起飞重量[MTOW]不低于120公斤）。其中最大的当属八吨级隐形CH-7，该机型正在为中国人民解放军研发。不过，中国航天科工集团公司决定升级CH-3/4/5系列机型，主要基于其操作灵活性和出口资质——这些机型已成功出口到至少8个国家。

 

The CH-3/4/5 UAV series also shares a common and interoperable datalink, which allows the UAVs to operate alongside each other, facilitating their integration into military networks. The three UAV models can be directed via a fixed or mobile ground control station (GCS) equipped with an encrypted C-band (4–8 GHz) datalink offering jam-resistant and line-of-sight (LOS) operations.

CH-3/4/5无人机系列还共享一个通用且可互操作的数据链，使无人机能够相互协同作战，促进其融入军事网络。三种无人机型号可以通过配备加密C波段（4-8GHz）数据链路的固定或移动地面控制站（GCS）进行指挥，提供抗干扰和视线（LOS）操作。

 

CASC's enhancements to the CH-3/4/5 series, which include the development of the new CH-5C version (known as the CH-9), include better range, higher top speeds, and the ability to operate at higher altitudes, according to information Janes has obtained from China's state-owned defence exporter, Poly Technologies.

根据简氏从中国国有国防出口商保利科技公司获得的信息，中国航天科技集团公司（CASC）对CH-3/4/5系列的改进包括开发新的CH-5C版本（被称为CH-9），包括更好的航程、更高的最高时速和在更高海拔运行的能力。
