French Aircraft Assembly Depot in Africa?

[Carl Schwamberger]

I ran across a remark that in June 1940 there existed a aircraft assembly/fitting depot in French NW Africa. The remark implied it was set up to assemble US built aircraft & maintain aircraft of all types. Does anyone know if this was infact true, & of any sources where I might confirm it & find details?

I had know the French navy had a considerable maintinace capability in its African bases but had seen nothing thus far on what the FAF might have had circa 1939-40

Thanks for any information or leads
