Grob is a company well known for sailplanes and powered gliders. It produced the G 110 in the early 1980s, and the G 112 in prototype form only; from these developed the G 115, whose prototype first flew in November 1985.

The prototype entered production as the G 115, constructed of glass fibre reinforced plastics. A second prototype with relocated tailplane and a taller fin and rudder became the G 115A. they remained in production until 1990.

Production recommenced in 1992 with improved models designated G 115 B to D, with further sub-variants. These were powered by engines up to 180 hp (135 kW), with other changes such as fuel in the wings, or variations to cabin glazing. A G 115TA Acro was also produced, with a 260 hp (195 kW) engine.
