 The Yak-23, known as Flora, was a development of the earlier Yak-15 and Yak-17 fighters. The Yak-23 used a Soviet copy of the British Rolls-Royce Derwent V turbojet engine. A small number of Yak-23’s were exported to Czechoslovakia beginning in 1949 and named S-101. B&W photo credit: Zdenek Cizinsky. Color photo credit: Global Aircraft.
