The China Cases

At least 9 defense scientists dead under unusual circumstances · 2018–2026
9 dead Military AI · Hypersonics · Drones · Space
While the FBI investigates 11+ American cases, at least nine Chinese scientists working in sensitive defense fields have also died under unusual circumstances since 2018. The fields overlap: military AI, hypersonic weapons, space defense, drone warfare, and nuclear-adjacent research. China’s Embassy says it is “not aware” of the situation. No official investigation has been announced.

The 9 Cases

ILLNESS
Yan Hong
Hypersonic aviation scientist · Professor & doctoral supervisor, Northwestern Polytechnical University (US-sanctioned) · Former Rutgers University & Wright State University, Ohio
Died Mar 24, 2026 · Age 56 · Jiangsu Provincial People’s Hospital
One of China’s leading researchers in supersonic/hypersonic flow control, plasma-based flow control, and computational fluid dynamics. Died reportedly following an illness. Previously held research positions at Rutgers University and Wright State University in Ohio — the same state as Wright-Patterson AFB where US case Matthew Sullivan worked. Returned to China to join Northwestern Polytechnical University, which the US sanctioned for ties to military research including fighter jets and hypersonic vehicles. NPU developed the Feitian 1 and Feitian 2 hypersonic aircraft.

MEDICAL EPISODE
Fang Daining
Chinese Academy of Sciences member · Chief Scientist, Institute of Advanced Structure Technology · Beijing Institute of Technology · Materials science & structural mechanics
Died Feb 27, 2026 · Age 68 · South Africa (business trip)
One of the most important scientists in China’s hypersonic weapons program. Specialist in super-strong materials for spacecraft and hypersonic vehicles. Founded BIT’s Institute of Advanced Structure Technology in 2015. Died suddenly while on a business trip to South Africa. CCP kept his death secret for weeks — no standard public announcement was issued despite his CAS membership. Social media posts about his death were rapidly deleted. Died the same day (Feb 27) that US Gen. McCasland disappeared from his home in Albuquerque.

Died Nov 16, 2025 · Age 49 · Guangzhou
Internationally renowned medicinal chemist and fellow of multiple international research societies. Broke through critical core technologies for visualizing target proteins in major diseases. Died of a sudden illness in Guangzhou at the height of his research career. China’s latest loss of a leading scientist at a productive age.

FELL FROM BUILDING
Zhang Daibing
Top drone expert · Deputy Director, NUDT Unmanned Systems Research Institute · Founded Yunzhihang Technology · Led 20+ national/military projects
Died Jan 3, 2025 · Age 47 · Changsha, Hunan
One of China’s foremost experts on drone warfare and swarming technology. Led 20+ national, military, and government projects. In 2021 his team developed high-voltage direct-drive technology allowing drones to carry 1,100+ lb payloads. Founded Yunzhihang Technology in 2017, which later faced severe financial difficulties. Fell from a building in the early hours of Jan 3. Official obituary gave no cause of death. Some reports suggest suicide due to financial strain; others speculate foul play. Third NUDT scientist to die unexpectedly.

CAR CRASH · BEIJING
Zhang Xiaoxin
Space physicist · National Satellite Meteorological Centre · Director, NSMC Space Weather Office · Co-chair, WMO International Space Weather Group · ICAO adviser
Died Dec 15, 2024 · Age 62 · Beijing
Leading space physicist who specialized in weather monitoring and early warning systems. Held international posts at the World Meteorological Organization and International Civil Aviation Organization. Won a top award from the Chinese military for science and tech progress. Second Chinese scientist with close military ties to die in a Beijing car crash — following Feng Yanghe 18 months earlier.

UNSPECIFIED ACCIDENT
Liu Donghao
Data scientist · Founder, Guizhou Big Data Protection Engineering Security Research
Died 2024 · Age 51
Prominent data scientist and founder of a big data protection and security research organization in Guizhou province. Died in an unspecified accident. Least documented case in the cluster — minimal public details available.

CAUSE UNSTATED
Zhou Guangyuan
Chinese Academy of Sciences member · Dalian Institute of Chemical Physics · Materials & polymers specialist
Died Dec 2023 · Age 51
Celebrated chemist specializing in advanced materials and polymers at one of China’s most prestigious research institutions. CAS member. No cause of death publicly stated. His materials research has potential dual-use applications in military aerospace.

CAR CRASH · 2:35 AM
Feng Yanghe
Colonel, PLA Strategic Support Force · Associate Professor, NUDT · Creator of “War Skull” AI platform · Harvard visiting scholar (2011–2013)
Died Jul 1, 2023 · Age 38 · Beijing
Born in Pingliang, Gansu. Entered NUDT in 2003, studied at Harvard’s Department of Statistics and High Performance Computing Lab (2011–2013), earned PhD from NUDT in 2014. After a 2014 military exercise, became determined to build AI command systems. Designed “War Skull” — China’s first AI system for military command and control. War Skull drafts operation plans, conducts risk assessments, and provides backup plans from incomplete tactical data. Used by 10+ PLA theater commands and defense industry departments by 2021. Modeled Taiwan invasion scenarios. Killed in a Beijing car crash at 2:35 AM after leaving a “major task.” Buried at Babaoshan (reserved for CCP elite). Obituary: “sacrificed while performing official duties” — language normally reserved for soldiers killed in action.

Critical Connections

The threads that link Chinese cases to each other — and to the American cluster
WeightWhoConnectionWhy it matters
STRONGESTFang Daining ↔ McCaslandChina’s top hypersonics scientist died the same day (Feb 27, 2026) that America’s most senior missing person — the man with legal visibility over all classified DoD programs — vanished from his home.Two rival superpowers’ most strategically sensitive figures gone on the same date. CCP censored Fang’s death for weeks.
STRONGESTNUDT × 3 deathsChen Shuming (2018, weapon chips), Feng Yanghe (2023, military AI), Zhang Daibing (2025, drones). Three scientists at the same military university, covering three pillars of China’s future warfare strategy.Mirrors LANL’s 3+ cases in the US cluster. NUDT is China’s most sensitive defense research university.
STRONGESTTwo Beijing car crashesFeng Yanghe (Jul 2023, 2:35 AM) and Zhang Xiaoxin (Dec 2024) — both military-connected scientists killed in Beijing car crashes 18 months apart.Beijing car crashes involving defense scientists is a statistically unusual pattern. Both had active military ties.
NOTABLEYan Hong ↔ Ohio / Wright-PattersonYan Hong worked at Wright State University in Ohio before returning to China. US case Matthew Sullivan was deputy director at NASIC, Wright-Patterson AFB — also in Ohio. Both involved in defense-adjacent work.Ohio is the geographic crossover point between the US and China clusters.
NOTABLETwo hypersonics deaths in 25 daysFang Daining died Feb 27. Yan Hong died Mar 24. Both were China’s top hypersonics researchers. 25 days apart.China lost its two leading hypersonics scientists within a single month. Both deaths had unusual circumstances (censorship, foreign illness).
NOTABLEFinancial pressure patternZhang Daibing faced severe financial difficulties before falling from a building. David Wilcock (US) also reportedly had “overwhelming financial debt” before his death.Financial pressure appears in both clusters as a pre-death circumstance. Could be genuine or could be a manufactured narrative.
NOTABLEHarvard / US academic tiesFeng Yanghe studied at Harvard (2011–2013). Yan Hong held posts at Rutgers and Wright State. Both later worked on China’s most sensitive military programs.US-trained scientists returning to work on PLA programs is exactly the pattern that triggered the DOJ China Initiative.
CONTEXTCCP information controlFang Daining’s death was censored for weeks. Zhang Daibing’s obituary gave no cause. Zhou Guangyuan’s cause was never stated. Social media posts deleted.Unlike the US cluster (congressional hearings, FBI probe, open press), China’s response is active suppression of information.
