The Potez 75 was developed by the reformed Potez Company which had originally been formed by Henry Potez in 1919. The type was designed to meet the requirement for a launching platform for wire-guided anti-tank missiles Nord SS.10. It was of all-metal construction, with a pusher engine. The twin fins and tailplane were carried on two booms extending from the lower rear fuselage and it was fitted with a fixed tricycle undercarriage. The missile operator sat in the nose, behind which was a small upper cabin accommodating the pilot Initially the operator's cabin had windows and the pilot's position was open, but later modifications enclosed the latter and provided the operator with better visibility by full glazing.
