GE has delivered the first GE38 engine for the US Marine Corps (USMC) CH-53K ground test vehicle after undergoing two years of testing and demonstrations.

The new turboshaft / turboprop engine is expected to provide the CH-53K aircraft, being developed by Sikorsky, with increased mission capability required for USMC missions.

The GE38 features a rugged compressor design for increased durability and is resistant to sand erosion and salt water corrosion.

The engine is said to be best suited for USMC’s tough operating environment and provides mission flexibility and enhanced hot / high aircraft performance.
