Three Belgian squadrons also flew French-built Sopwiths, and surplus French Sopwiths were used by several countries postwar. During the war, several Strutters that were interned after landing in the Netherlands were purchased for the Dutch Luchvaart Afdeeling. Over 100 Strutters were also built in Russia by Duks and Lebedev, supplemented by large numbers delivered directly from Britain and France. The Strutter remained in large scale use by both the Soviet forces and White Russians during the Russian civil war and Polish-Soviet war. Three were captured during this war and used by the Poles in 1919–1920. Other captured ones were used by Baltic states. The American Expeditionary Force purchased 384 two-seat Strutter observation aircraft and 130 single-seat bombers from France in 1917–18. While mainly used for training, they were used operationally by the 90th Aero Squadron as an interim measure, due to a shortage of later types. The U.S.Navy used a number of the two-seat Sopwiths, along with Nieuport 28s and Hanriot HD.1s and 2s as ships' aircraft in the early postwar years, testing the use of aircraft from platforms mounted on the turrets of battleships. The Strutter also served with the Imperial Japanese Army Air Force – some examples serving in the Japanese expeditionary force in Siberia during 1918. Around 1,500 Strutters were built for the Royal Flying Corps and the Royal Naval Air Service and between 4,200 and 4,500 were built in France. A single aircraft acquired from Russia in 1918. Two aircraft registered in 1928. R-105 (later LV-BAA) and R-106 (later LV-CAA). One of these two preserved in Florida. 55 aircraft on French civil register in 1922. At least seven aircraft registered. Possibly one aircraft from Switzerland in 1926. Two aircraft, CH-53 registered 9 April 1921, cancelled 9 October 1923. CH-67 registered 5 December 1923, cancelled December 1926 as sold to Sweden. One civil registered aircraft, G-EAVB. Original Sopwith Strutter aircraft are preserved at the following locations.
