Historical
Squadron E-12 was to be equipped
with Latécoère 521 "Lieutenant de Vaisseau Paris"
and Latécoère 522 "Ville de Saint-Pierre".
But these two aircraft will eventually be assigned to Squadron E-6
who lost by accident, one of his 3 Latécoère 523.
It is therefore decided to
equip the Lioré & Olivier LéO H426 Escadrille
E-12, but only one aircraft, the No. 4, will be delivered before
the Armistice. It is not yet operational when the flight ban occurs.
