US military aircraft engine advanced technology programs were overviewed and analyzed from light weight gas generator (LWGG) program initiated in 1960s through integrated high performance turbine engine technology (IHPTET) program started in 1980s

then to versatile affordable advanced turbine engine (VAATE) program. Some features and trends were summarized and concluded by literature statistics method

such as teams based on closely corporation among government

industries and academics

goals oriented with national defence strategies and weapon system development requirements

engineering manufacture and development including all relative disciplines and areas

verification measured by technology readiness level

the application extending to military aircraft engine

civilian engine

gas turbine and space vehicle

etc. The experience and lessons obtained can provide reference and guide for technology research and engineering manufacture and development of military aircraft engines in the world.
