RUAG Space to supply payload fairings for H3 rocket

(10 April 2019 - RUAG Space) RUAG Space and Mitsubishi Heavy Industries (MHI) have signed a contract for RUAG Space to develop a payload fairing and payload supporting structures for the H3 launch vehicle.

After development, RUAG Space will produce three sets of payload fairings and supporting structures, and provide engineering support for the launch campaigns.

“We are the leading payload fairing suppliers,” says Peter Guggenbach, RUAG Space CEO. “Now we are truly global, supplying to the launcher industry on three continents.”

Protecting an ISS resupply spacecraft

The H3 is the new Japanese flagship launch vehicle, which is being developed by the Japan Aerospace Exploration Agency (JAXA) and MHI to succeed the H-IIA and H-IIB rockets. It will be 63m high with a diameter of 5.2m. RUAG Space payload fairings and supporting structures are planned to be used on three resupply missions to the International Space Station, which will be done by the HTV-X cargo spacecraft. The HTV-X is a planned successor to the HTV Transport Vehicle, which has been used for resupplying the International Space Station since 2009. Its first flight is expected in the Japanese Fiscal Year 2021.

“We are delighted to receive support of RUAG, a highly experienced and trusted supplier of space products. We have enjoyed working with a Japanese partner for standard types of fairings and supporting structures for our families of launch vehicles for many years. We will build up trusted partnership with RUAG to help us transport critical cargos to the ISS,” said Masahiro Atsumi, Vice President & Senior General Manager for Space Systems at MHI.

Composite structures for launch vehicles

RUAG offers several sizes of payload fairings, from a diameter of 0.7m for small launch vehicles up to 5.4m fairings. Almost 300 launches have taken place since 1979 with RUAG fairings on board – with 100% mission success. RUAG Space also develops and produces interstage adapters and other payload supporting structures. All of these are built in composite technology based on aluminium honeycomb cores with plastic face sheets reinforced by carbon fiber. This ensures the necessary combination of high stiffness and low mass. RUAG Space has manufacturing facilities in Emmen, Switzerland and Decatur, Alabama, USA.
