[1][2] A revised, Standard competition class version, the WA 21 Javelot II made its first flight on 25 March 1958.

This has a modified wing with a span of 15 m (49 ft 3 in) and 4° of dihedral on the outer parts though none on the constant chord centre section.

The Javelot II also introduced separated pairs of differential ailerons as well as altering the wing to fuselage connection.

[2] The final production variant, though one that continued to be improved, was the WA 22 Super Javelot, which first flew in June 1961.

It had a Super Javelot fuselage fitted with a new, 18 m (59 ft 1 in) span wing, an aspect ratio of 22 and a new airfoil profile specially designed by Maurice Collard.
