The Rolls-Royce MT30 marine gas turbine has been selected to power Australia’s new fleet of up to 11 general-purpose frigates, following Australia’s decision last year to procure Japan’s upgraded Mogami-class as a replacement for its existing general-purpose frigates, according to Rolls-Royce.
The Mogami-class is already powered by the MT30 in Japanese service, and the Royal Australian Navy has confirmed it will retain the same engine for its variant of the platform. The first three ships will be built in Japan by Mitsubishi Heavy Industries and exported to Australia, with the first scheduled for delivery in 2029 and operational service from 2030.
Alex Zino, Director of Business Development and Future Programmes, UK and International at Rolls-Royce Defence, said the company was “delighted to continue this long-standing partnership by powering their new general-purpose frigates with our MT30 engine” and added that Rolls-Royce was “pleased to support this collaboration between two nations that are combining capabilities to enhance the security across the region.”
In addition to the MT30 gas turbine, the upgraded Mogami-class frigates will be equipped with mtu Series 4000-based diesel generator sets from Rolls-Royce Power Systems, supplied through licensed partner Daihatsu InfinEarth, providing onboard power generation for a range of ship systems.
The MT30 is designed, assembled and tested at the Rolls-Royce site in Bristol and is in service with several navies globally, including the Royal Navy’s Queen Elizabeth-class aircraft carriers and Type 26 frigates, the US Navy’s Freedom-class Littoral Combat Ship and Zumwalt-class destroyers, and the Republic of Korea Navy’s Daegu and Chungnam-class frigates. The engine will also power Australia’s Hunter-class frigates, which are being built as part of a separate programme under the AUKUS framework, giving the Royal Australian Navy a degree of commonality across its major surface combatant fleet.
Rolls-Royce said the MT30 is the world’s most power-dense marine gas turbine currently in service, according to the company, offering power margin and platform design flexibility alongside efficiency and reliability through the life of the vessel.
There was no other gas turbine to select in the market.
Which is good for RR as they have carved a massive niche with a good product.
I’ve gained $17,240 only within four weeks by comfortably working part-time from home. Immediately when I had lost my last business, I was very troubled and thankfully I’ve located this project now in this way I’m in a position to receive thousand USD directly from home. Each individual certainly can do this easy work & make more greenbacks online by visiting

Indeed, the announcement is redundant from an engineering standpoint since the Mogami is built for and of the MT30. I suspect this is more to do with Australia confirming it will be ordering MT30s for the units built in country. May as well get your orders on the books etc.
Good work
Awesome
It’ll be interesting to see down the track a comparison between the T31 with CIP against the RAN Mogami in capability, performance and cost wise as both are GP frigates.
Easy win for the Japanese warship.
“Easy” ?
Going by the Jap version it seems easy win except less 2 40mm guns for a RAM
1×5″
32 MK41 VLS
8 SSM
RAM
planar AESA > 360º permanent coverage.
Towed array sonar.
A 5″, mk41, SSM, towed sonar can all be added and the radar can potentially be upgraded on the T31. Range and survivability too must be factors.
Good good. It’s nice to see RR is on the mend.
Does anyone ever hear about economies of scale on the MT30 passing down to the RN?
Rodders must be VERY happy with his shares at the moment.
