On June 6th last the French military aviators with their armoured and armed aëroplanes were reviewed at Villacoublay by General Joffre and General Bernard, the director of military aëronautics. Amongst the types of aëroplanes present was the Dorand biplane, having two Gnome motors driving separate screws, armoured in its vital parts, and armed with a Hotchkiss mitrailleuse. This was mounted on a pivot, and could be fired in almost every direction. There were, too, the Morane-Saulnier, Blériot-Gouin, Nieuport, and Breguet-Bristol types. M. Raymond, in his speech before the Senate in February last, said that Germany was in possession of armoured aëroplanes, but that France had none. The June review at Villacoublay showed what vast strides in military aëroplane construction the French had made in a few months. The French military aëroplanes consist of Farman types, and many other leading French forms. In 1913 there were about 500 French military aëroplanes and a few naval hydroplanes. France manufactures a great number of aëroplanes, of late years about 1,000 per year. These include Government machines, those of private owners and export machines. There are at least twenty-nine French flying grounds, many of them flying schools and trial grounds of the leading French airship and aëroplane makers. In 1913 Italy appears to have had about a hundred military aëroplanes, including those on order, Blériots, Bristol (monoplanes), Farmans, Nieuports, and others. She had six or eight naval aëroplanes. She is well provided with military flying schools and other flying grounds, nearly all fitted with hangars. There are military airship hangars at Rome, Milan, Verona, Venice, and Bracciano. Belgium has a military school of aviation near Antwerp, and in 1913 she had as many as twenty-four military aëroplanes--H. Farman, 80 h.p. Gnome. There are in Belgium about half a dozen flying grounds, and as many aërial societies or clubs. As already stated, Germany, in the first instance, looked to Austria-Hungary for her aëroplanes, and the Etrich was an Austrian machine. In late years, however, Austria’s aëroplanes were mainly Lohners; the Government favoured this make and discouraged others, consequently enterprise and invention languished. After the accident to the Aspern the Lohner was condemned as of too feeble a resistance, and meanwhile discouragement had effaced all the other systems. Aëroplanes are used both in the Russian army and navy. Those of the navy are hydro-aëroplanes, or capable of being so arranged. In number, the Russian navy has about a dozen. Of military aëroplanes Russia has probably from 250 to about 300, many of them of modern type, and built in Russia, the principal types being Rumpler, Albatross, Aviatik, Nieuport, Farman, Bristol and Deperdussin. Bulgaria has a number of aëroplanes, mainly Blériots and Bristols. SYKORSKY’S GIANT AËROPLANE.
