Role	Open-class sailplane
National origin	Germany
Manufacturer	Schleicher
Designed by	Gerhard Waibel
First flight	8 July 1981
Number built	87

The ASW 22 is an Open Class glider built of modern fibre reinforced composites including carbon-fibre and Kevlar. The manufacturer of the ASW 22 is Alexander Schleicher GmbH & Co. The 'W' indicates that this is a product of the German designer Gerhard Waibel.

The ASW 22 Open Class successor to the ASW 17. It first flew in 8 July 1981 as a 22 metre glider. The span was increased to 25 metre for the ASW 22B with a modified inner wing section and flaperons similar to the ASW-20. It uses a Horstmann and Quast wing profile on the inner section with underwing tubes to collect high-pressure air which is then expelled through turbulator holes in the bottom wing skin ahead of the flap and aileron hinge line to prevent the separation of the laminar flow. The ASW-22 has a two-wheel retractable udercarriage, and the only sailplane in the world to have this.

An ASW 22 broke the world 750 km speed triangle record in 1985 and other ASW 22s have won first place in six World Gliding Championships.

The two-seat Schleicher ASH25 uses the same wing with a two-seat fuselage.
