The top Allied ace of WWI flew a SPAD with a 37 mm cannon firing through the propeller hub
René Fonck ended WWI as the top Allied ace with 75 confirmed victories, second only to the Red Baron. I got curious about the machines behind that number, so here they are in order.
- Caudron (1915-1917). He spent almost two years flying recon, first in the G.III, then in the twin-engine G.4. He had a Lewis gun fitted over the top wing. In July 1916 flak knocked out one engine and he made it home on the other. His first confirmed victory came in a Caudron: in August 1916 he herded a German Rumpler down until it landed behind French lines and the crew surrendered.
- SPAD VII (1917). His first real fighter after joining Escadrille 103 of the "Storks" group. 150 hp Hispano-Suiza, one Vickers gun.
- SPAD XII. The odd one. A 37 mm cannon sat between the cylinder banks and fired through the hollow propeller shaft. Single shot, reloaded by hand in flight. Very few pilots could use it well, and Fonck is credited with around 11 victories on it.
- SPAD XIII (1918). His main machine: 235 hp, two Vickers guns, about 222 km/h, 8,472 built. With it he twice shot down six aircraft in one day, on 9 May and 26 September 1918. On the second day, three of the six were Fokker D.VIIs.
His method was simple: stalk a two-seater, get close, one short burst. By his own account, only one enemy bullet ever hit his plane.
Fun fact: after the war his personal plane was registered F-ONCK.
SPAD XIII or Fokker D.VII, which one would you rather fly in late 1918?
