The Shcherbakov Shche-2 (), also known as the TS-1 and nicknamed "Pike", was a twin-engined utility aircraft manufactured in the Soviet Union, designed by Alexei Shcherbakov for construction by OKB-47, to meet an urgent requirement for a light transport and liaison aircraft for operation by the Soviet Air Force during the Second World War. Proving to be successful, it remained in service for a number of years post-war in both civilian and military roles in the Soviet Union, and with the air forces of several allied nations.
