The Bloch MB.210.01 prototype flew for the first time in November 1934as a bomber developed from the MB.200 with cleaner lines, a new tail, smooth metal fuselage skinning, the wing dropped from the shoulder to the low-set position, and retractable landing gear in place of the original strut-braced and spatted fixed gear
A second prototype was designated Bloch 211 N°1 Verdun. Following tests, the production version was ordered as the Bloch 210. A cantilever low-wing monoplane which retained the angular lines of the high-wing Bloch 200, the Bloch 210 was powered by two 678kW Gnome-Rhone 14N engines and had a retractable landing gear, the main units of which retracted into the engine nacelles. Armament comprised single 7.5mm MAC machine-guns in a nose turret and semi-retractable dorsal and ventral positions. Maximum bomb load was 1,730kg.
The first production machine flew on 10 December 1935.
As part of its opposition to the Nationalist cause in the Spanish Civil War, France supplied 35 MB.210s to the Republicans. In March 1937 the arrival of these aircraft allowed many of the obsolescent Breguet Bre.19s to be phased out of service with Grupo num 22, which received a mixed complement of Potez Po.540s and MB.210s. Though useful by the standards of the civil war, there was little that these bombers could achieve against the Nationalists’ steadily growing air superiority, and none survived to fall into Nationalist hands at the end of the war.

A total of 283 were eventually built for the Armee de l’Air, with which they served in the BN5 (five-crew night bomber) category. Final deliveries to the air force were made in February 1939, by which time the aircraft was obsolete.
By September 1939 238 Bloch 210s served with French bomber Groupes, employed on limited night operations including leaflet raids. However all were withdrawn from first-line service by June 1940. Twenty-four Bloch 210s had also been exported to Romania in 1938. Ex-Vichy aircraft were supplied by the Germans to Bulgaria in 1942.

When, in 1932, the French air ministry circulated its specification for a five-seat night bomber, there were eight proposals from five companies. Both Bloch and Farman were successful on this occasion, although the resulting production aircraft were completed in differing bomber categories.
The MB.200 was finalised as a four-seat bomber, with a cantilever high-wing monoplane of all-metal construction, and non-retractable tail-wheel type landing gear. The prototype Bloch M.B.200.01 had two 567kW Gnome-Rhone 14Krsd radial engines, and was first flown in July 1933. Subsequent flight testing resulted in an initial order for 25 aircraft, placed on 1 January 1934, despite the maximum speed of the prototype 18 per cent below estimate.
When the production M.B.200 began to enter service towards the end of the year, it was found to be both reliable and viceless, and though production aircraft had more powerful Gnome-Rhone engines, still slow. 208 were eventually supplied to the Armee de I’Air, built by Bloch (4), Breguet (19), Hanriot (45), Loire (19), Potez (111) and SNCASO(10).
At the beginning of World War II seven front-line bomber groupes were still equipped with these obsolete aircraft, but at the time of the German offensive all had been relegated to a training role. The type had also been built under licence in Czechoslovakia by Aero and Avia, and these were seized by the Germans, serving as crew trainers and for general duties, as were those which had been captured in France. Many were passed on to German satellites.

Aero built 44 Bloch 200 heavy bombers as the MB.200, and Avia licence built 70 machines powered by two 700 Walter K-14 engines.

The Bloch MB.130 and its derivatives were a series of French monoplane reconnaissance bombers developed during the 1930s. The MB.130 was developed in response to the August 1933 French Aviation Ministry request for a reconnaissance and tactical bomber.

The low-wing Bloch 130 was a smaller version of the Bloch 210, but with a fixed and trousered undercarriage. The Bloch 130.01 Guynemer prototype first flew on 29 June 1934. Despite very ordinary performance, soon entered production, 40 machines being ordered in October 1935. An improved version, the MB.131 was first flown on 16 August 1936, but still needed more work to overcome its deficiencies. The radically revised second prototype which flew on 5 May 1937 eventually formed the basis for series production, with aircraft being manufactured by SNCASO, the nationalised company that had absorbed Bloch and Blériot.

As with the Potez 540, given the role that the aircraft was expected to fill, the evaluation was cursory and simply confirmed that the aircraft was completely unsuited to the intended role and should not be considered further.

A total redesign led to the Bloch 131, with a glazed nose and tall single fin and rudder, and powered by two 708kW Gnome-Rhone 14N radial engines. A retractable undercarriage was fitted. Armament comprised 7.5mm machine-guns in nose, dorsal turret and ventral positions.

The single Bloch 133, with a new twin fin and rudder tailplane, was later converted to a standard Bloch 131.

One hundred and thirty-nine production Bloch 131 were built for the Armee de l’Air in the RB4 category as four-crew machines intended for bombing and reconnaissance. The first six aircraft were delivered by June 1938, the rest by September 1939. Entering service in June 1938, the MB.131 went on to equip seven reconnaissance Groupes, six in metropolitan France and one in North Africa. Upon the outbreak of the war, the metropolitan Groupes suffered heavy losses in attempts at daylight reconnaissance of Germany’s western borders. From October 1939 they were restricted to flying night missions, though they still suffered heavy losses even then, and for training. The max bomb load in various combinations was 800kg. By May 1940, all metropolitan units had been converted to Potez 63.11 aircraft, with only the African groupe retaining them for front-line duty.

Following France’s capitulation, the Vichy regime used surviving Bloch 131s for target-towing. 21 planes were reported captured by the Luftwaffe in inoperable condition, but photographic evidence suggests at least a few flew for the Nazis.
