After completion, single catapults were installed on the quarter-decks of each ship, initially with two Gourdou-Leseurre GL-812 HY flying-boats, later the GL-832.
Even well into the 1930s, specialised aerobatic versions were produced as the B6 and B7 for Jérôme Cavalli and Fernand Malinvaud respectively, with a second B7 built for Adrienne Bolland.
A number of these were sold to the government of the Second Spanish Republic and to the Basque Nationalist Party.
