The Yak-23 was the final development of the highly successful Soviet fighter series which began with the Yak-1 in 1940. Its immediate predecessors were the Yak-15 and Yak-17, both simple jet-powered versions of the wartime Yak-3, but the Yak-23 was an updated all-metal version of the basic design. It saw service with several Warsaw Pact air forces, as a lightweight fast-climbing interceptor. The design, development and operations of the Yak-15, -17 and -23 are described and illustrated in this book, which is copiously illustrated with photos, scale plans, drawings and colour profiles. An essential guide to these first-generation Soviet fighter aircraft!
