As first flown, the D 37 bore little resemblance to the D 371

Transferred by the SAF-Avions Dewoitine to the Liore-et- Olivier (LeO) concern owing to the workload imposed on the parent company by the D 50bis (future D 500), the D 37 (later D 370) was a private venture contender in the 1930 C1 programme. The prototype, flown on 1 October 1931, was powered by a 700hp Gnome- Rhone 14Kbrs Mistral Major 14-cylinder two-row radial. It was subsequently subjected to an extensive series of modifications: a G-R 14Kbs engine gave place, in turn, to a G-R 14Kds affording 800hp for take-off and 740hp at 4500m; the engine cowling was changed; the undercarriage was redesigned, and the wing introduced dihedral and reduced chord. Yet more redesign was embodied by a second prototype, the D 371, which appeared late February 1934. Twenty-eight D 371s were ordered for the Armee de l'Air with the G-R 14Kf s engine of 930hp for take-off and 880hp at 3250m, and an armament of four underwing 7.5mm MAC 34 machine guns. Fourteen were ordered by Lithuania, and these, having two synchronised 7.7mm Browning guns in the fuselage and two Darne guns of similar calibre in the wings, were designated D 372s. Twenty were ordered for the Aeronautique Navale as D 373s, these having flotation gear, an 30cm reduction in wing span and an armament of four Darne guns within the wing. A further 25 ordered for this service with aft-folding wings were designated as D 376s. The last D 371 left the factory at the end of December 1935, the Armee de l'Air fighters following the Navy's D 373s. The Lithuanian government meanwhile relinquished its D 372s in favour of D 501s, the former being sold to the Spanish Republican government and ferried to Spain during August 1936, where they were later joined by 10 of the 28 Armee de l'Air D 371s. The remaining D 371s equipped an escadrille at Bizerte, Tunis, until 1939, but were little flown owing to constant problems with their engines. The D 373s and D 376s of the Aeronautique Navale suffered similarly, and by September 1939, only 13 D 373s and nine D 376s were on strength, all being withdrawn before the year's end.
