Early Sopwith Triplanes were powered by a nine-cylinder, 100 hp Clerget
9Z rotary engine, but most were fitted
with a 130 hp Clerget 9B rotary
engine. Several companies built a total of 150 Triplanes. They saw
service
beginning in June 1916.
Sopwith Triplane
This home-built replica of a Sopwith Triplane was built by Akron pilot Bill Woodall from original Sopwith plans. It is powered by a Le Rhone rotary engine.
