Designed to meet a requirement for a three-seat fighter with an endurance of three hours at 90% max speed, the Potez 670 was configurationally similar to the Potez 630 and 631. Flown for the first time on 30 March 1939, the Potez 670 had meanwhile been modified as a two-seat long-range escort fighter and bomber destroyer. Initially powered by two 700hp Gnome- Rhone 14M radials, it was re-engined after initial flight trials with two 800hp Hispano-Suiza 14AB 12/13 radials, with which it resumed flight tests in July 1939 as the Potez 671. Several production variants were proposed, but flight trials were incomplete at the time of the French collapse and the sole prototype was destroyed during the German onslaught. At the time, work had begun on an initial batch of 40 Potez 671 C2 fighters.
