The GL.30 was the basis of a new fighter, the GL.31, which had a greater span, almost double the wing area, a fixed undercarriage, and a Gnome-Rhône 9A engine.

31 was not flown until 1926 and then abandoned, overtaken by the GL.32, the company's entry in a 1923 Aéronautique Militaire competition to select a new fighter.

In French service, development turned from fighters to adapting the aircraft as a carrier-borne dive bomber.

Another aircraft was supplied to the Basques in 1937, modified as a dive bomber along the lines of the previous French experiments.

Designated the GL.633, this aircraft was used by Miguel Zambudio to attack the Nationalist battleship España, scoring decisive hits that contributed substantially to her subsequent sinking.
