ASW 25 Glider

The ASH 25 is a two-seater high performance Open Class glider manufactured by Alexander Schleicher until September 2008, originally with a 25 meter wingspan. Designer Martin Heide (the 'H' in the type designation) combined the wing of the World Championship winning single-seater Schleicher ASW 22 with fuselage derived from the Akaflieg Stuttgart FS-31 which had particularly low drag. The prototype was designated 'AS 22-2'. The span was increased in later versions to 25.6 or 26 metres with winglets.
