The prototype for the Mitsubishi A6M1 Reisen, or “Zero Fighter” (Allied code name “Zeke”) makes its first flight at Kagamigahara, Japan. The Zero would serve with distinction from Pearl Harbor until the end of the war and is probably Japan’s most famous World War II aircraft. Almost 10,500 were built.
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.
