This retro livery with its bright orange surfaces closely resembles the famous NB-52A and NB-52B test aircraft, serving as a reminder of the B-52’s rich history and continuing evolution. Starting back in 1957, the NB-52 aircraft were selected as launch pads for experimental aircraft such as the legendary X-15 hypersonic aircraft, or tested new equipment in support of the NASA space shuttle program. The last of these special Test BUFFs (Big Ugly Fat Fellows) were retired in 2004. By adopting the heritage orange livery, the 49th Test an Evaluation Squadron not only honors these past experimental aircraft but also symbolizes the ongoing modernization of the Stratofortress strategic bomber. Despite entering service in 1961, the B-52H remains a cornerstone of U.S. air power, with upgrades ensuring its viability until at least 2050.
