The Department of the Air Force issued a Notice of Intent on February 11, 2026, to prepare an EIS for basing one squadron of up to 21 F-16 Block 40 aircraft at the Idaho Air National Guard Base at Gowen Field in Boise, Idaho. The action replaces 21 A-10C Thunderbolt II aircraft, which are being divested Air Force-wide by FY2029. The EIS will evaluate environmental consequences of the beddown, operations, and supporting facility construction, alongside a No Action Alternative. The Federal Aviation Administration is a cooperating agency. Potential significant impacts include aircraft noise, air quality, and land use. A 30-day scoping period opened with the notice.12
