The first E-3 Sentry with upgraded DRAGON flight deck modifications arrived at Tinker AFB, Okla., earlier this month. The AWACS aircraft, which was delivered to the 552nd Air Control Wing, is the first of 24 that will be upgraded over the next eight years, according to a press release. The upgrade enables the Sentry to remain in compliance with changing domestic and international air traffic control requirements. It also replaces older analog flight management systems with commercial-level digital ones, and fully automates the navigation system. As such, the standard crew size will be reduced from four to three on the modified aircraft. The AWACS modernization program was first announced in October 2014 as a joint effort with NATO. NATO completed a first round of testing on the new Sentry in January of 2015.
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.
