Aeroderivative gas turbine family for marine propulsion and industrial applications.
by GE Aerospace
Initial operation aboard GTS Adm. Callaghan
Manufacturer history dates initial operation to 1969 without a month or day.
U.S. Navy awards Spruance-class engine contract
GE received a contract for LM2500 propulsion on Spruance-class destroyers. The manufacturer’s history specifies the month.
1,000th LM2500 turbine delivered
GE’s retrospective chronology dates the thousandth turbine delivery to 1990; it is a fleet delivery total rather than a first delivery.
LM2500+ development and testing begin
Development and testing began for the higher-output LM2500+ variant. It remains part of the LM2500 family timeline in this dataset.
LM2500+ enters industrial service in the Netherlands
The first application of the LM2500+ variant was a cogeneration plant in Dordrecht. This dates variant service, not the original LM2500 introduction.
LM2500+ receives U.S. Navy certification
The U.S. Navy certified the LM2500+ variant for mechanical-drive applications rated at 35,000 brake horsepower.
LM2500+G4 variant introduced
GE’s chronology dates introduction of the fourth-generation LM2500+G4 to 2005. The variant remains within the family record.
Composite module completes shock testing
An LM2500 with a new composite enclosure and updated components underwent shock testing at the HI-TEST facility in Virginia.
Navy qualification of composite module announced
GE announced U.S. Navy qualification of the modernized module. The release gives an announcement date, not the precise certification date.
Orders announced for two further Flight III destroyers
GE reported orders for eight LM2500 engines for the future USS Intrepid and USS Robert Kerrey. The release does not identify the contract execution date or establish delivery.
