The Potez 633 was the light bomber variant of the Potez 63 family of aircraft. It had a two man configuration, with a pilot and rear gunner. The aircraft proved to be relatively ineffective as a bomber in the Battle of France, suffering heavy losses due to enemy air superiority and the mediocre speed of the Potez 633, a problem shared with its interceptor counterparts, the Potez 630 and 631. While other nations such as China, Romania, and Greece also used the Potez, not all of them were delivered due to a French embargo on army equipment and other military assets in June 1939. The aircraft also served with Vichy France, although relegated to second line service.

Introduced in Update 1.73 "Vive la France", the Potez 633 lacks the 20 mm cannons and additional 7.5 mm MGs for offensive armament compared to the Potez 630 and 631, instead having a single 7.5 mm MG mounted in the nose. The aircraft has adequate ordnance for a light bomber of its BR, being capable of carrying a total of 400 kg of bombs in the form of eight 50 kg or two 200 kg bombs. The 200 kg bombs are the most adequate for dealing with ground targets, and can be used with good results in ground battles against light tanks. It should be noted that the Potez is particularly weak against SPAA due to its low speed and large size when compared to biplanes or ground attackers.
