Chuo Engineering Contributes to the Successful Release of Satellites on H3 Rocket No. 6 via Space BD's Rideshare Launch Service

Chuo Engineering, Inc. (Headquarters: Chiyoda-ku, Tokyo; President and CEO: Yutaka Ishida; hereinafter referred to as "Chuo Engineering") announced that the "H3 Rocket No. 6 (30-type test vehicle)" equipped with the multi-satellite support interface plate, for which Chuo Engineering provided development support, was launched from Tanegashima Space Center on June 12, 2026, at 9:53:59 AM. The release of the four satellites carried as rideshare payloads was confirmed.

Chuo Engineering was commissioned by Space BD Co., Ltd. to handle the design, analysis, manufacturing, assembly, and various tests for the development of the "interface plate," which enables the release of multiple satellites from a single payload port.

This project was conducted as part of Space BD Co., Ltd.'s "H3 Rocket Rideshare Launch Service," and Chuo Engineering contributed to its realization through the development of the "interface plate."

This achievement confirmed that the "interface plate," which Chuo Engineering has consistently provided development support for, meets the specified performance requirements under launch environment conditions in actual operation.

Furthermore, in this development, engineers from different specialized fields such as structural design, analysis, and manufacturing collaborated to establish a development process that iteratively repeats design and analysis in a short period. This has enabled the realization of optimal designs in a short timeframe, addressing the stringent environmental conditions and high reliability requirements unique to spacecraft.

Leveraging the development expertise gained through this project, Chuo Engineering will continue to contribute to the advancement of Japan's space business and the enhancement of its international competitiveness by leveraging its advanced manufacturing capabilities in the spacecraft field and its one-stop solution service that provides everything from design and analysis to manufacturing and testing.
