| In 1934, the Service Technique issued an outline specification
for a new single-seat fighter, all the contenders
but one having all-metal stressed-skin monocoque
structures with enclosed cockpits and retractable
undercarriages. The structural exception was the MS
405. The Loire 250 was powered by a 1000hp Hispano-
Suiza 14Ha-79 two-row radial and was first flown on 27
September 1935 temporarily with a fixed-pitch two-bladed
wooden propeller. Intended armament comprised
two synchronised 20mm cannon and two
7.5mm machine guns, but trials with the Loire 250
proved disappointing from the outset, the prototype
suffering serious drag problems. Various palliatives
were applied to reduce drag, the vertical tail was redesigned
to rectify a stability problem and a three-bladed
variable-pitch propeller was fitted. Nonetheless the
fighter proved incapable of attaining the max speed of
"at least 485km/h" called for by the specification,
and thus the Loire 250 was eliminated from the
contest at an early stage.
