China’s FAST telescope targets full domestic supply chain by 2028, plans 64-telescope array
China’s Five-hundred-meter Aperture Spherical Radio Telescope (FAST) aims to achieve a fully domestic supply chain for all core components by around 2028, replacing currently imported phased-array and 19-beam receivers. Chief Engineer Jiang Peng also announced plans to build 64 additional 40-meter radio telescopes around FAST, forming a unique comprehensive aperture array expected to improve resolution by 200 times and sensitivity by about two times.

China's FAST Telescope Aims for Fully Domestic Supply Chain by 2028
According to a report by CCTV Finance, cited by Tencent Stock, the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) project in China is expected to achieve a fully domestic supply chain by around 2028. Jiang Peng, Director and Chief Engineer of the FAST Operation and Development Center, stated that the team has spent years working on replacing key components with domestic alternatives, using a phased approach starting with terminal feeds and progressing to RF circuit amplifiers and chips. Currently, the phased array and 19-beam receivers still rely on imported equipment. Jiang expressed hope that by around 2028, all core components of FAST will be domestically produced. Additionally, plans are underway to build 64 radio telescopes with 40-meter apertures around FAST, forming a comprehensive aperture array system. This system, the only one of its kind globally, is projected to increase FAST's resolution by 200 times and its sensitivity by about two times. Since its inauguration in September 2016, FAST data has contributed to 13 papers in top journals like Science and Nature, with its achievements recognized multiple times by major scientific awards.

In an interview with CCTV, Jiang Peng, Director and Chief Engineer of the FAST Operation and Development Center, stated that the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) is working towards achieving a fully domestic supply chain for its components, including phased arrays and 19-beam receivers, by around 2028. He noted that these components are currently imported. Jiang also outlined a major expansion plan to build 64 radio telescopes, each 40 meters in diameter, around FAST to form a comprehensive aperture synthesis array. This array, the only one of its kind centered on a giant telescope, is expected to improve FAST's resolution by 200 times and its sensitivity by about 2 times. Jiang explained that this upgrade would allow scientists to study neutral hydrogen galaxies from the universe's most active period, around 10 billion years ago (redshift 2), an area where current human knowledge is lacking.

Jiang Peng, director and chief engineer of the FAST Operation and Development Center, stated that China has spent several years progressively developing domestic alternatives for components from terminal feeds to RF circuit amplifiers and chips. Currently, phased-array feeds and 19-beam receivers are still imported, with a target of full localization by around 2028. Jiang also announced a plan to build 64 radio telescopes, each 40 meters in diameter, around the FAST site. This would form a synthetic aperture array centered on the world's largest single-dish telescope, a configuration unique globally. Once completed, the array is expected to improve FAST's resolution by a factor of 200 and increase its sensitivity by approximately two times.

FAST Aims for Full Domestic Supply Chain by 2028, Chief Engineer Says
According to a report by CCTV Finance cited by 格隆汇 on September 26, Jiang Peng, Director and Chief Engineer of the FAST Operation and Development Center, stated that the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) is working toward full domestic production of its components. Jiang noted that efforts have been underway for several years, progressing from terminal feeds to RF circuit amplifiers and chips. Currently, the phased array and 19-beam receiver are still imported, but the goal is to achieve complete domestic supply by around 2028. Jiang also revealed plans to build 64 radio telescopes with 40-meter apertures around FAST, forming a comprehensive aperture array centered on the giant telescope. This array, unique globally, is expected to improve FAST's resolution by 200 times and increase its sensitivity by approximately two times once completed.
