Glenn L. Martin doubled the size of the Baltimore factory, and built all 115 aircraft in six months, but they were then prevented from delivering them by a US government arms embargo. Despite this the French placed an order for an additional 100 aircraft. The embargo was lifted in October 1939, and the 115 aircraft from the first order were delivered by late November 1939. Deliveries then slowed, and only 25 of the second batch reached France before the Armistice of 22 June 1940.
