FFX Batch III frigates to use MT30 engine
The Rolls-Royce MT30 marine gas turbine will power the Ulsan-class Batch III frigates being built by Hyundai Heavy Industries for the Republic of Korea Navy (RoKN).
According to Shephard Defence Insight, the new Ulsan class will consist of six new improved frigates to replace aging escort and patrol ships currently in RoKN service. The frigates will displace 3,500t and measure 129m in length with a beam of 15m. They will be capable of operating at a maximum speed of 30kt.
Rolls-Royce previously worked with the RoKN to introduce a hybrid propulsion system for all eight Daegu-class FFX Batch II ASW frigates. Each of these vessels is 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,’ Rolls-Royce announced in a 2 December statement.
