Jiang Peng, director and chief engineer of the FAST Operation and Development Center, announced that the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) is working toward full domestic production of its components by around 2028. He stated that efforts have been underway for several years to replace imported parts, including terminal feeds, RF circuit amplifiers, and chips, with locally made alternatives. Currently, the phased array and 19-beam receiver are still imported. Jiang also revealed plans to build 64 radio telescopes, each 40 meters in diameter, around FAST to form a comprehensive aperture array centered on the giant telescope. This array, described as the only one of its kind globally, is expected to improve FAST's resolution by 200 times and increase its sensitivity by approximately two times once completed. The information was reported by CCTV Finance via Cailianshe on September 26.

September 26 (Cailianshe) — The Five-hundred-meter Aperture Spherical Radio Telescope (FAST) is expected to achieve full domestic production across its entire supply chain by around 2028, according to Jiang Peng, Director and Chief Engineer of the FAST Operation and Development Center.
Jiang noted that the team has spent several years progressively working backward through the technology chain—from terminal feeds and RF circuit amplifiers to chips. Currently, the phased array and 19-beam receivers are still imported. The goal is to achieve complete localization by approximately 2028.
Jiang also revealed plans to build 64 radio telescopes, each with a 40-meter aperture, around the FAST site. These will form a comprehensive aperture array centered on FAST—the only such array in the world built around a giant telescope with medium-aperture telescopes surrounding it.
Once completed, the array is expected to improve FAST's resolution by a factor of 200, while simultaneously increasing its sensitivity by approximately twofold.
