What model type engine is used in the EA-18G?

• A. F135-PW-1000 high bypass.
• B. JT9D.
• C. CFM56-5.
• D. F414-GE-400 low bypass, axial flow, dual-spool turbofan engine of modular construction and afterburner.

Answer: (D)

The Growler uses a twin-engine F414-GE-400 turbofan. This engine is a low-bypass, axial-flow, dual-spool design with an afterburner, and it’s the same family used on the F/A-18E/F Super Hornet. That combination—low bypass for high thrust, dual-spool architecture for efficient operation across speed ranges, modular construction for maintenance, and afterburner for added power when needed—fits the EA-18G’s fighter/attack role and performance profile. The other options describe engines not used on this aircraft: the F135-PW-1000 powers the F-35; the JT9D is an older engine from widebody jets; the CFM56-5 is a high-bypass engine used on many commercial aircraft, not a fighter.
