JMSDF selects Rolls-Royce’s MT30 gas turbine for FFM-class frigates

The Japan Maritime Self Defence Force (JMSDF) has selected Rolls-Royce for the delivery of MT30 gas turbines to power the fleet of 30 new FFM-class frigates.

The Japan Maritime Self Defence Force (JMSDF) has selected Rolls-Royce for the delivery of MT30 gas turbines to power the fleet of 30 new FFM-class frigates.

Japan is set to become the fifth country to use Rolls-Royce’s MT30 gas turbine for a major naval shipbuilding programme as a result of the selection.

Construction work on the first of the 30 planned frigates is slated to commence next year and the vessel is expected to enter service with the JMSDF around 2022.

“The power and performance of this modern gas turbine is providing shipbuilders and system designers with new options, choices and the ability to future-proof their latest naval platforms.”

Rolls-Royce senior vice-president Sam Cameron said: “The MT30 is the world’s most power-dense marine gas turbine in service today, a key feature for naval ships where high power in minimum space, whilst meeting the operational power demands of the future, is essential.

“The increased demand for power by the world’s navies is a clear trend and for Japan we will deliver a power rating in excess of 40MW, the highest so far for this gas turbine unrestricted by global climate conditions.

“The power and performance of this modern gas turbine is providing shipbuilders and system designers with new options, choices and the ability to future-proof their latest naval platforms, combined with the additional benefits of through-life power retention with ultra-low on-board maintenance requirements.”

Rolls-Royce has designed the MT30 gas turbine to feature nearly 50% fewer parts than other aero-derived gas turbines of the same class in an effort to minimise maintenance costs.

The equipment features a twin-spool, high-pressure-ratio gas generator with a free power turbine.

It is also able to maintain operating efficiency down to power levels of 25MW.

In addition, MT30 is capable of being configured in either mechanical, electrical or hybrid drive configurations.

The gas turbine first entered service in 2008 on-board the US Navy’s first-of-class littoral combat ship (LCS), USS Freedom.

The MT30 turbine was also recently installed to power the British Royal Navy’s newest Queen Elizabeth-class aircraft carrier, HMS Queen Elizabeth.
