SPAD S.XIII 
First flight 4 April 1917

The SPAD S.XIII was a single-engine biplane fighter aircraft. In terms of its construction, it shared a similar configuration and layout to the earlier S.VII,featuring a mainly wooden structure complete with a fabric covering; however, it was generally larger and heavier than its predecessor. Other changes included the tapered chord of its ailerons, the rounded tips of the tailplanes, bulkier cowling accommodating the gear-drive Hispano-Suiza 8B engine choice, and enlarged fin and rudder. The S.XIII was armed with a pair of forward-mounted Vickers machine guns with 400 rounds per gun, which took the place of the single gun that had been used on the earlier aircraft..
