The ASW 27 is a 15 metre Class glider built of modern fibre reinforced composites, which first flew in 1995 and was certified in 1997.

The ASW 27 has plain flaps, winglets, a retractable undercarriage and a water ballast system.

The structure is a complex composite of carbon, aramid and polyethylene fibre reinforced plastic.

This was a design decision to pursue an uncompromised 15 metre racer, as "future engine retrofits or later wingspan increases were specifically ruled out".

The introduction of the ASG 29 gave the ASW 27 a stablemate that can compete in the same class, although the 29 is intended to fly primarily with an 18-metre span and can be motorised.
