ALG A-9 D history:

During the development of Operation Overlord, the Allies plan to create ALG A-9 to become an airfield dedicated to transport operations (coded “Cargo”) insofar as it is built on the border between the American and the British front.

But with the evolution of the fighting, supply needs are very pressing: the ALG A-9 is mainly used as a center of exploitation of aerial photographs (with the 17th Signal Operation Battalion) and as a depot for maintenance equipment at benefit of Allied aviation (with the 16th Air Depot Group belonging to the 2nd Advanced Air Depot Area). Instead of carrying the letter “C” of Cargo as expected, the airfield then bears the letter “D” for “Depot”. However, it retains a mission of transport authorities due to its proximity to Montgomery’s headquarters, located east of Blay.

Huge prefabricated Butler-type hangars and semi-Romney-type hangars were set up in the technical area of ​​the aerodrome for the storage of the means of supply and the accommodation of the personnel.
