General Characteristics
The SPAD S.XVI was a French two-seat reconnaissance and light bomber biplane of World War I, introduced in early 1918. It was a derivative of the earlier SPAD S.XI, but was re-engined to address reliability issues found in its predecessor’s engine. Though it offered only marginal performance improvements and retained poor handling, approximately 1,000 units were built and it served with 32 French escadrilles by the time of the Armistice.
