the star of World War II, of French Naval Aviation was the first Allied bomber to raid Berlin: on the night of 7 June 1940 aircraft of this variant dropped eight bombs of 250 kg and 80 of 10 kg weight on the German capital. This operation, which was of a primarily psychological-warfare nature, was repeated three days later. The first NC 223.3 bombers were delivered in May 1940 and participated in night bombing attacks on Germany before being transferred to North Africa in June 1940. The bombers were subsequently relegated to transport roles, seeing service with both the Vichy regime and the Free French. The F.224 was a dedicated civil variant able to seat 40 passengers. Six machines were produced for Air France, but were ultimately rejected because the 224 could not maintain altitude on three engines. The aircraft went on to serve in the Armée de l'Air instead with a reduced payload.
