The Wassmer WA 26 Squale (English: Shark) is a single seat, 15 m (49 ft 3 in) span competition glider, designed and produced in France in the late 1960s.

The Wassmer WA 28 Espadon (English: Swordfish) is an aerodynamically very similar development with a glass fibre wing.

Like the Javelots, it had a wooden wing but one with a Wortmann profile; its fuselage was a more aerodynamically refined and wholly GRP structure.

The straight edged, swept fin and rudder, the latter horn balanced, are GRP structures, integral with the fuselage.

[4] Recognition that wooden-winged gliders were becoming outdated resulted in a redesigned wing, aerodynamically the same as the WA 26 Squale but built of GRP and fitted with Schempp-Hirth rather than trailing edge airbrakes.
