CASC Rainbow
series of Chinese-designed unmanned aircraft models
CASC Rainbow (Chinese: 彩虹; pinyin: cǎihóng, abbreviation CH) is a series of unmanned aerial vehicles (UAVs) marketed by China Aerospace Science and Technology Corporation (CASC). The series includes multi-role medium-altitude long-endurance UAVs and micro air vehicles (MAV). The UAVs are produced by CASC's China Academy of Aerospace Aerodynamics (CAAA).
Series
CH-1
The CH-1 is a small fixed-wing reconnaissance UAV. Development started in 2000.
CH-2
The CH-2 is a small fixed-wing reconnaissance UAV.
CH-3
The CH-3 is a fixed-wing unmanned combat aerial vehicle (UCAV). It first flew in 2007. The CH-3 has a 70 kg payload, and can carry the AR-1 air-to-ground missile and FT-9 guided bomb.
The Pakistani NESCOM Burraq may be based on the CH-3; the Burraq is armed with the Burq missile, which may be based on the AR-1.
CH-4
Externally, the CH-4 looks almost identical to the General Atomics MQ-9 Reaper, with the only distinct visual difference between the two UAVs being the ventral fin below the V-tail on MQ-9 which is absent on the CH-4. There are two versions, the CH-4A and CH-4B. The CH-4A is a reconnaissance drone (capable of a 3500–5000 km range and a 30- to 40-hour endurance life) while the CH-4B is a mixed attack and reconnaissance system with provisions for 6 weapons and a payload of up to 250 to 345 kg.
Begin with the source’s own compact description: “CASC Rainbow” is series of Chinese-designed unmanned aircraft models. The dossier treats that line as a proposition to test through CASC, Rainbow and series, not as a finished interpretation.
Why this record matters
The phrase “series of Chinese-designed unmanned aircraft models” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 2, 2026. The linked authority identifier is Q16924279. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2000 and 2007.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
