“The modifications are focused on updating the jets’ structural and mission systems architecture, enabling future capability growth for the US Navy’s 160 Growler aircraft,” Boeing said, adding, “The programme schedule forecasts that all US Navy Growlers will be modified in five years. Full rate modification is expected to start in June 2021.”
Previously known as the Advanced Growler, the Growler Block 2 enhancement is based on the F/A-18E/F Super Hornet Block 3 upgrade that is now in its early stages. Features common to both aircraft comprise 10 × 19 inch large-area display (LAD) cockpits (front and back) and conformal fuel tanks (CFTs), while the Growler will also receive enhancements to the mission systems including the Next-Generation Jammer (NGJ) and EA sensors improvements related to the Electronic Attack Unit (EAU) Surrogate Processor (ESP), AN/ALQ-218(V)4 RF receiver system, and AN/ALQ-227(V)2 communication countermeasures. There will also be networking and crew-interface improvements.
