What type of engine powers the EA-18G Growler?

• A. Turboprop engine.
• B. Pratt & Whitney PW4000.
• C. GE F404-GE-400 high flow turbojet.
• D. F414-GE-400 low flow by-pass axial flow turbo fan engine of modular construction with afterburner.

Answer: (D)

This question tests propulsion type for the Growler. The EA-18G is powered by two GE F414-GE-400 engines, a low-bypass axial-flow turbofan with an afterburner. This arrangement gives the aircraft the jet-like speed and high thrust needed for carrier ops and high-performance flight, while the afterburner provides extra thrust for short bursts such as takeoff or combat maneuvers. The engine family on the Growler is the same as that used on the F/A-18E/F, replacing the older F404 used on earlier Hornets.

Turboprops are out because this aircraft relies on jet propulsion, not propellers. The Pratt & Whitney PW4000 is a different family used on some larger airliners and not the Growler’s engine. The F404-GE-400 is the earlier engine for the Hornet family, not the engine installed on the Growler. The F414-GE-400 with afterburner matches the Growler’s performance and maintenance design, making it the correct choice.
