Designed before the war as a military patrol flying boat, the Type 731 Bellatrix was test flown at the Berre naval air base in unoccupied France in 1942, the prototype Type 730 having been flown just before World War 2.
The Type 731 differed from the pre-war Type 730 in having re-designed crew accommodation, modified floats, and a strengthened hull. The Type 731 escaped destruction and, after the war, it was re-engined with four 1480 hp Gnome-Rhone 14R radials and was used by the French Naval Air Service.
Only one Type 731 Bellatrix was completed.
