It was a single-seat monoplane with a composite structure and wooden wings.The Yak-1 was extremely manoeuvrable, fast and well armed, and, just as importantly, it was easy to maintain and reliable. It formed an excellent basis for subsequent developments from the Yakovlev bureau."@en . . . "1940Z"^^ . . "1944Z"^^ .
