Abstract: Marine gas turbines dominate the power of large and medium-sized surface warships， which is an important symbol of naval modernization. This paper reviewed the development history of marine gas turbines in the world， and introduced the development of marine gas turbines from Aero-Derivative and independent development. The technical characteristics and performance of typical marine gas turbines LM2500 series， MT30 and UGT25000 were analyzed. Then， the development direction of marine gas turbines in terms of improving power and thermal efficiency， improving reliability and maintainability， developing product serialization and pedigree， etc. are prospected. And， the key technologies that need to be developed in the aspects of materials and manufacturing processes， metal additive manufacturing， aerodynamic design， low emissions， cooling and thermal barrier coatings， dual-fuel， intelligent and hybrid power， etc. are put forward.
