The LM2500 + G4 is the latest born in the LM family of aero derivate turbines, produced for  marine and industrial applications. Produced models have accumulated to date more than 40 million hours of service, with an average reliability of 99.6%.
The LM2500 gas turbine has benefited over the years for continued improvement. Today, the LM2500 + G4 offers an installed capacity amounting to 32 MW.

Avio's share in this programme is 9%. Avio covers the role of supplier for the FREMM program (Italy-France) for the construction of 27 Frigates, on each Frigate is installed a propulsion system equipped with an LM2500 + G4.

A new design and development of the turbine module with important advantages:

• Significant reduction of weight
• Noise Reduction
• Development of new Turbine Control System
