The Rolls-Royce MT30 marine gas turbine has been selected for the Republic of Korea
Navy’s (RoKN) FFX Batch III frigate, known as the Ulsan-class frigate which will be built by
Hyundai Heavy Industries.

Rolls-Royce has already successfully worked with the RoKN to introduce a revolutionary,
modern and simple, hybrid propulsion system arrangement for all eight ships in the Daeguclass FFX Batch II Anti-Submarine Warfare frigate programme – each powered by a single MT30 gas turbine and electric propulsion motors powered by four Rolls-Royce MTU diesel generators per ship.

The use of the MT30 across the Batch II and Batch III frigates will deliver commonality
benefits to the customer, such as spare parts, support infrastructure and training.
For FFX Batch III, the Ulsan-class frigate programme, Rolls-Royce will also supply Engine
Health Management (EHM) capability with its MT30 marine gas turbine. Supporting leaner
naval forces, EHM technology delivers through-life benefits, such as reduced manpower and
maintenance costs, by enabling the collection of reliable engine data and analysis to
maximise asset availability and optimise on-board maintenance.

As part of Rolls-Royce’s on-going design collaboration with Hyundai Heavy Industries (HHI)
for the specialised integrated gas turbine enclosure for MT30, HHI-EMD will continue to be
responsible for the manufacture of this highly complex engineering enclosure and all
ancillaries in-country, as well as continuing to provide in-service support.

Jay Lee (Jongyel Lee), Vice President of Business Development & Future Programmes,
Defence – Naval, Korea said: “Today, Rolls-Royce remains at the forefront of naval
propulsion technology. MT30 is powering many of the world’s most advanced platforms in
all conceivable propulsion configurations. We are delighted that MT30 has once again
© 2020 Rolls-Royce has been selected to power the latest batch of FFX frigates and we look forward to continuing our relationship with the Republic of Korea Navy and HHI.
“MT30 first entered service with the Republic of Korea Navy’s Daegu-class in 2018. Its
selection for FFX Batch III is a testament to the confidence that our customer has in the
proven performance of this modern and superior engine.”

MT30 Marine Gas Turbine: Rolls Royce

“Selecting the right power and propulsion system is one of the most important decisions
our customers will face when designing their new platforms. We are committed to working
closely with the Republic of Korea Navy to provide them with the most adaptable
propulsion systems based on the most modern technology available today. This will
ensure our customers can retain their military advantage via future technology insertion
without having to endure costly upgrades to legacy power generation capability
throughout the life of their ships.”

Designed for the 21st century, MT30 is proven at sea, delivering long-term reliability,
unrivalled life-long performance with operating cost efficiencies. The MT30 gas turbine is
already in service with several navies around the globe including the U.S. Navy’s
Freedom-class Littoral Combat Ship and Zumwalt-class destroyers, the Republic of
Korea’s Daegu-class frigates, the Royal Navy’s Queen Elizabeth-class aircraft carriers
and the Italian Navy’s new Landing Helicopter Dock. More recently MT30 has been
selected to power the Japanese Maritime Defence Force’s advanced 30-FFM frigate and
in single gas turbine CODLOG (Combined Diesel Electric or Gas) configuration for the
Type 26 Global Combat Ship programmes for the Royal Navy, Royal Australian Navy and
Royal Canadian Navy.

Beyond the FFX programme, the power density of the proven naval MT30 gas turbine
genset is also one of the key enablers for Integrated Full Electric Propulsion (IFEP) for the
next – generation RoKN destroyer (KDDX). Rolls-Royce’s extensive experience in IFEP
powered warships such as the Royal Navy’s Type 45 destroyers and Queen Elizabeth class
aircraft carriers, and the U.S. Navy’s Zumwalt-class destroyers, will support the
RoKN’s technological ambitions and their SMART Navy Vision 2045, delivering game-changing military capability in next-generation destroyers.
