US spy planes keep close eye on China amid live-fire military exercises
- American aircraft goes unusually near naval base on east coast, think tank says
- Patrols also carried out over disputed South China Sea, with aircraft going dark around Paracels, it says

A US spy plane buzzed the Chinese coast this week, one of several warplanes deployed close to Chinese territorial waters amid live-fire exercises by the PLA Navy, according to a think tank.
Last week, US spy planes patrolled along the southeast coast of Guangdong province before heading south to the disputed Paracel Islands, also in the South China Sea, according to open-source aviation radar responder records.
The think tank said the aircraft involved in the patrols last week and on Wednesday temporarily “disappeared” from public radar records when flying over the eastern to northern section of the Paracels, possibly “having turned off their responders”.
State broadcaster China Central Television said near-shore patrols enabled planes to detect electronic signals on land in their mission to collect intelligence on the PLA.
