Boeing recently delivered the first production EA-18G Growler to the Navy, “ahead of schedule and within budget,” according to a Boeing release. The Navy plans to have the Growler replace the EA-6B Prowler, which it has contracted Northrop Grumman to upgrade to prolong its usefulness through 2018. Even with the extended Prowlers and the new Growlers, Pentagon officials acknowledge an electronic attack coverage gap.
The rate of building B-21 bombers would speed up if the fiscal 2026 defense budget passes. But it remains unclear how much capacity would be added, and whether the Air Force would simply build the bombers faster, or buy more.
