was involved in a propaganda flight to Berlin in August 1938 to convince the Germans that the French employed modern bombers. Though 130 machines were ordered by the French government that year, production delays and modifications ensured that by September 1939 none had been delivered. 830 of this very modern aircraft were eventually ordered but only 80 machines were received by the Air Ministry. The main variant was the twin-tailed 351; due to delays, the single-tailed 354 was accepted into service as an interim type. The Amiot 351 was intended to carry a

Operational history

In May 1940, the Amiot 351/354 was in the process of equipping just two bomber ''groupes'': GB 1/21 and GB II/21 based at Avignon. Though 200 were in the final stages of construction, only 35 were ready for flight. This situation was exacerbated by the Amiot 351/354 being built in three factories, two of which were later bombed by the Germans. On 16 May 1940, the Amiot 351/354s carried out armed reconnaissance sorties over

in the Netherlands - the first operation conducted by planes of this type. By June, the Amiot 351/354 was also delivered for GB I/34 and GB II/34, neither flying them in combat. At that time, all Amiot 351/354s were based on the northern front. Three had been lost in combat and ten in training accidents. All aircraft were ordered to evacuate to Africa on 17 June, 37 surviving the trip. As their numbers were too few to engage the
