 at the former site of the Martin Aircraft Company. They built civilian biplanes, float planes, as well as biplane torpedo bombers under contract to the US Navy. The model that most people think of today when someone says, "Great Lakes aircraft," is the enduring 2T biplane; also known as the Great Lakes Sport Trainer. It was designed and sold as a two-place, open cockpit biplane. The first engines were an 85 hp (63 kW) American Cirrus

 came it was lowered to $3,985. The first four Sport Trainers built were of a rare straight-wing design, one of which was modified into a special racer. Because of problems recovering from flat spins, the top wing was swept back and that is what most people recognize first when looking at a Sport Trainer. At its peak, Great Lakes had as many as 650 deposits for new aircraft. With the onset of the great depression, the Great Lakes Aircraft Company went out of business closing their doors in 1936. The company built just 264 of the Sport Trainers ordered.

Re-establishment of the company

. There have been a great number homebuilt Great Lakes Sport Trainers built over the years, which kept interest in this old biplane alive.

In the later 1970s, the Great Lakes 2T-1A was built in Eastman, Georgia. After a run of three or four years, the factory was closed.

In 1973 Doug Champlin brought the Great Lakes back into production in Oklahoma. The general design was not changed much. The fuselage was strengthened by using thicker walled tubing, and the engines used were 150 or 180 hp Lycomings. The wings utilized Douglas Fir in place of Sitka Spruce

. The factory rights were sold to various people until 1985, when production ceased. Doug Champlin also built one Turbine powered Great Lakes 2T. With 420 hp (310 kW), it was quite a show stopper.
