JS Potchefstroom

WHO ARE WE?

Jonker Sailplanes Pty Ltd. (JS) is a privately owned, South African company that designs, manufactures, and maintains sailplanes from their main facility based at the Potchefstroom Airfield. It was originally a small team of three engineers and three technicians who combined their knowledge to produce a sailplane that would win competitions and fly beautifully. These six were the beginning of the original JS1 success story. Ten years later there are 16 qualified engineers and more than 110 employees working in the Jonker Sailplanes factory in South Africa. With M&D Flugzeugbau in Germany now further strengthening the team, the company has become a force to be reckoned with!
