The Messerschmitt Bf-109a fighter prototype makes its first flight at Augsburg, Germany. More than 32,000 Bf-109s will be built (including post-war versions in Spain and Czechoslovakia) in a multitude of versions, making it the second most produced aircraft of all time. (Most produced: Ilyushin II-2; see entry for Dec. 30, 1939.)
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.
