"The idea to design a deck dive crafter itself originated in the early 1930s. Based on all the advantages and disadvantages of the existing schemes, Nieuport engineers came to the conclusion that a modern aircraft should be a monoplane with a closed cockpit of pilots and, if possible, with a retractable landing gear. This approach provided the best aerodynamic qualities and allowed maximum use of the engine's power characteristics to ensure a higher speed. With the first two points the problem did not arise. Moreover, they decided to abandon the retractable landing gear. This was done for several reasons - saving weight, reducing the load on the pilot, and if you break the wing in the form of a "reverse gull", then in the place of the break, you can very compactly install the fairings and place a bomb load or brake shields in them. They decided to make small arms as powerful as possible. The engine was equipped with a 20 mm motor cannon and additionally supplied one 7.5 mm machine gun. While making out the external appearance of the aircraft it became clear that the Ni 140 would strongly resemble the Ju-87A. The Germans quite rightly accused the French of stealing drawings, although most likely we are talking about adopting the ideas of German specialists. Indeed, by the time of its appearance, the Ni 140 struck the eye with the huge fairings of the chassis racks and the typical water-cooling motor that gave the Nieuport airplane the closest resemblance to the Junkers. However, there were differences. The French dive bomber originally had a single-keystone vertical tail, and the brake flaps were installed in the rear of the fairings, when installing radiators in the front. However, all this will be later. "
