Korean company Hanwha Aerospace will now produce engine turbine components for Rolls-Royce’s Trent engine family, as part of an expanded long-term partnership.

The 25-year contract, valued at $1 billion, will also see Hanwha build a second production facility in Vietnam, where it will produce components.

In total, Hanwha will produce 10 key parts for the Trent engines. These include combustion rear inlet cases, aircraft engine inter-cases, as well as other frames.

Hanwha says it plans to set up an exclusive production line for R-R at its Vietnam site, which began operations late last year. It discloses that it is building a second plant, also in Vietnam, which will be completed by the first half of next year.

The parts produced by the Korean firm will travel to R-R’s Derby plant, where it will then be assembled and tested.

R-R and Hanwha’s relationship date back to 1984, when the latter provided military MRO services for R-R engines. It later took on engine component manufacturing and is currently the only gas turbine engine manufacturer in Korea.

The Hanwha Group is looking to pump in $3.4 billion by 2022 to improve the competitiveness of its aerospace business. In the past five years, the company has signed long-term aircraft engine component supply contracts — worth about $19.8 billion — with R-R, GE, as well as Pratt & Whitney.
