The high rate of attrition of allied fighter aircraft resulted most of the SPAD S.VII being produced equipping French squadrons and as an interim solution 100 aircraft were produced under licence in Russia at the Duks factory in Moscow, a further 220 aircraft were licence built by "Mann Egerton" and "Blériot & SPAD" in the UK. The licence built aircraft suffered reliability and performance problems as a result of low material and construction standards, the British built aircraft were retained as trainers and the RFC used the French built aircraft it could obtain as operational fighters, when in 1917, America entered WW1 they brought 189 SPAD VII's for the States Army Air Service where most were used as trainers in preparation for the much improved SPAD XIII fighter aircraft.
