Was the EF-10 Skyknight the US Navy's first electronic-warfare carrier aircraft?
Short answerIt is treated here as the first purpose-built US Navy carrier electronic-warfare aircraft, followed by the EA-6B Prowler and then the EA-18G Growler.
NotesThe exchange clarifies that electronic support did not begin with the Growler. The EF-10B Skyknight established an early purpose-built carrier role, the EA-6B Prowler became its successor, and the EA-18G Growler continued the mission on a newer airframe. This lineage helps explain electronic attack as an enduring air-group function rather than a recent accessory. It also separates a purpose-built electronic-warfare aircraft from earlier platforms that may have carried jamming equipment only as an adaptation.
