EVOLUTION: Developed from the Amiot 370, holder of several world’s speed-with-load records, the Amiot 340 bomber has been ordered in large numbers for the French Air Force. The prototype 370 had liquid-cooled Hispano 127 engines giving a maximum speed of 305 m.p.h. at 16,400ft. The 340 bomber has more powerful two-row Gnome-Rhone radials. On the record machine the pilot looked forward through the transparent nose portion, the fuselage form being uninterrupted, but in the production bomber a projecting cockpit enclosure is fitted. The span is 75ft. 6in.

FAST AND FAR: The French Amiot 370 (two special Hispano Suiza 12Y engines) in which M. Rosse, on an unsuccessful attempt to break the world’s speed record for 10,000 km. and the record for distance in a closed circuit (now held by Japan), averaged more than 186 m.p.h. for 3,728 miles. The Japanese record is 115.5 m.p.h. for about 6,876 miles. The Amiot took off at a weight of 22,217. It is generally similar to a type of bomber now in production for l’Armee de l’Air.

With two Hispano-Suiza Series Y engines of 860 h.p. each, the Amiot 370, which has lately made its first flights, is estimated to be capable of 295 m.p.h.

RECORD HOLDER: Used by Rossi to set up three new international records, this Amiot 370, with liquid-cooled, 900 h.p. Hispano-Suiza 12 Y 21 engines, closely resembles a new production Amiot bomber. The maximum speed of the machine is probably as high as 290 m.p.h. A Gnome-Rhone radial-engined version has also been produced.

The main fuel load of the Amiot is carried in the fuselage, as shown, although additional tankage is provided in the wings.
