Bloch MB.150 (1937)[1]

The Bloch MB.150 was the first in a series of fighter types developed in France during the late 1930s.



A contender for the 1934 fighter programme, the Bloch MB.150 was a single seat all metal monoplane designed by Maurice Roussel, and powered by a Ghome Rhone 14 Kfs 14 cylinder radial rated at 930 hp at 14,270 ft (4,250 m).[2] Following a number of unsuccessful attempts to get the aircraft to leave the ground[N 1] the prototype received a larger wing, longer stroke undercarriage and, eventually, an direct drive GR 14N-07 engine delivering 970 hp at 14,928 ft (4,550 m).[4] However, the difficulties in making the detailed design required a complete structural redesign to permit large scale production and the addition of several aerodynamic refinements,[5] leading to development of the MB-151.[3]


Initially fitted with a 920 hp (686 Kw) Gnome Rhone 14N-11 radial engine, the MB.151 first flew on 18 August 1938 as the MB.151.01. A total of 144 MB.151C-1 aircraft were eventually constructed. These were mainly used for pilot conversion and fighter training, following the introduction of the improved MB.152.[6]
