The Grob G 115 is a general aviation fixed-wing aircraft, primarily used for flight training. It is built in Germany by Grob Aircraft (Grob Aerospace before January 2009). The E variant with a 3-blade variable pitch propeller is in Royal Navy, Army Air Corps and Royal Air Force service as an elementary flying trainer.

The aircraft is constructed of carbon composite materials. The main fuselage and each wing spar is a single piece. It has a fixed (sprung steel) tricycle undercarriage with spatted wheels, a short nose bearing the 180 hp engine and a 3-bladed variable-pitch propeller. The aircraft was re-certified in 2013 with a new MT Propeller following issues with the previous design. The inverted oil system was also redesigned to improve lubrication during aerobatics. The cockpit features a broad canopy arch and spine. Forward visibility is good. The side-by-side seats are fixed and pilot seating is adjusted with cushions as well as a rudder bar adjuster. The wings are tapered with square tips and the empennage consists of a large fin and rudder with an oblong tailplane with square tips mid-set to the fuselage.

The initial Grob G 115 and G 115A models had an upright fin and rudder and were mainly sold to civilian aeroplane clubs in Germany, the United Kingdom and several other countries.

The aircraft is capable of basic aerobatic manoeuvres (limited to +6G and -3G).

The Grob Heron was first bought by the Royal Navy. After its use five were bought by Tayside Aviation. There are only six recorded Herons in existence; two (to be sold) operated by Tayside Aviation, three privately owned and one in Germany. One was reported as written off after an accident.
