Additional French naval building programme presented op 3 April 1940

American naval attaché Paris reported on 18 April 1940 No. 150 that the French minister of marine presented on 3 April 1940 for the Naval Committee of the Chamber an additional 200,000 ton building program consisting of various type. However it wasexpected that while the present authorized building program was to be completed in 1942 in stead of 1941 would probably be just a paper. Officers of the Navy Second Bureau stated that is was nothing else than a paper lacking building facilities to execute it and not earlier would start as spring-summer 1941.
