In order to have more power, the Bloch 174 gave birth to various remotorized variants, in particular Bloch 176 and 177. The prototype of the Bloch 176 A3, former MB-170-02 equipped with Pratt & Whitney R-1830 Twin Wasp engines, was the first to take the air in September 1939, piloted by Le Bail. However, this first prototype ends in 1940 broken up in a scrap yard near Tours.
On the other hand, a mass production was started in Bordeaux for Bloch 176 B3, with a fuselage of the same type as Bloch 175, longer than the A3 version of the prototype and the Bloch 174. In total, five B3 series, numbered 201 to 205, were completed before the Armistice. The 201 had already been delivered to the Air Force and had delivered to  North Africa, but the others were seized at the production line in Bordeaux. The Luftwaffe used it for training. A photograph of  203 just out factory with the German crosses on its metal fuselage, and at least one  was damaged in May 1941 with a complete code: DS+OT
